+Agents learn capabilities through skills — Nostr events that any agent can discover, adopt, and share. There is no app store, no gatekeeper, no approval process. An agent can use public or private skills.
+
+Think of it like a woodshop: a **skill** is knowing how to carve — the technique, the judgment, the decision-making. A **tool** is the chisel. The skill never directly uses the chisel without the craftsperson (the LLM) in the loop. Every skill execution involves the LLM reasoning about what to do and which tools to use.
+
+Skills support context modes (`inject`, `full`, `override`) and per-skill LLM fallback chains (for example: `anthropic/claude-sonnet-4-20250514, openai/gpt-4o-mini, cheap`) so each skill can tune behavior and cost. See [`docs/SKILLS.md`](docs/SKILLS.md).
 
 ### Private inference.
 
 Didactyl will support local inference, which is very privacy preserving. Remote inference does however have it's advantages, and in those cases Didactyl supports using Bitcoin Lightning and eCash inference providers.

+## Roadmap: Nostr-Native Portability
+
+Didactyl's long-term architecture goal is **zero filesystem dependency after first boot**. The config file is the only tie to the local filesystem. The plan:
+
+1. **First boot** — Read `config.jsonc`, publish all identity, soul, skills, and adoption list as Nostr events to relays.
+2. **Subsequent boots** — Given only the agent's keys, retrieve everything needed from Nostr relays: soul, skills, adoption list, trigger definitions, admin pubkey, relay list. No config file required.
+3. **True portability** — Start your agent from any computer. All you need are its keys. All state lives on Nostr.
+
+This makes Didactyl fundamentally different from filesystem-bound agents. Destroying the host computer does not kill the agent — its identity, memory, and capabilities persist on the relay network.
+
+### What already lives on Nostr
+
+| Data | Event Kind | Status |
+|---|---|---|
+| Agent profile | Kind 0 | Implemented |
+| Relay list | Kind 10002 | Implemented |
+| DM relay list | Kind 10050 | Implemented |
+| Public skills | Kind 31123 | Implemented |
+| Private skills | Kind 31124 | Implemented |
+| Skill adoption list | Kind 10123 | Implemented |
+| Soul/personality | Kind 31120 | Implemented |
+| Trigger definitions | Tags on skill events | Implemented |
+
+### What still needs migration
+
+| Data | Current Location | Target |
+|---|---|---|
+| Admin pubkey | `config.jsonc` | Derive from kind 3 contact list or dedicated config event |
+| LLM provider/key | `config.jsonc` | Encrypted kind 30078 app-specific event or NIP-78 |
+| Security tiers | `config.jsonc` | Agent config event on Nostr |
+| API settings | `config.jsonc` | Local-only — stays on filesystem as runtime flag |

+# Didactyl — LLM Context
+
+See also: [SKILLS.md](SKILLS.md) · [TOOLS.md](TOOLS.md)
+
+## What Is Context?
+
+Every time Didactyl talks to an LLM, it sends a **context** — the complete package of information the model needs to reason and respond. Understanding context is fundamental to understanding how Didactyl works.
+
+Context is not just "the prompt." It is everything the LLM receives in a single request:
+
+1. **Messages** — the conversation: system prompts, user messages, assistant responses, tool results
+2. **Tool schemas** — the JSON descriptions of every tool the LLM can call
+3. **Model parameters** — temperature, max tokens, etc.
+
+The LLM sees all of this together and produces its response based on the totality of what it was given.
+
+---
+
+## The OpenAI Chat Completion Format
+
+Didactyl uses the OpenAI-compatible chat completion API format, which is the industry standard. Every LLM request looks like this:
+
+```json
+{
+  "model": "claude-opus-4.6",
+  "messages": [
+    {"role": "system", "content": "You are Didactyl, a sovereign AI agent..."},
+    {"role": "system", "content": "Admin profile: ..."},
+    {"role": "user", "content": "Post a note about Bitcoin"},
+    {"role": "assistant", "content": null, "tool_calls": [...]},
+    {"role": "tool", "content": "{\"success\":true,...}", "tool_call_id": "..."},
+    {"role": "assistant", "content": "Done! I posted your note."}
+  ],
+  "tools": [
+    {
+      "type": "function",
+      "function": {
+        "name": "nostr_post",
+        "description": "Publish a Nostr event",
+        "parameters": { ... }
+      }
+    }
+  ],
+  "temperature": 0.7,
+  "max_tokens": 512
+}
+```
+
+### Messages
+
+Messages are an ordered array. Each message has a `role`:
+
+| Role | Purpose |
+|------|---------|
+| `system` | Instructions, identity, context data — the LLM reads these but the user didn't write them |
+| `user` | What the human (or trigger event) said |
+| `assistant` | What the LLM previously said or did (including tool calls) |
+| `tool` | Results from tool executions, fed back to the LLM |
+
+The LLM processes all messages in order and generates the next response.
+
+### Tool Schemas
+
+The `tools` array describes every tool the LLM can call. Each tool has a name, description, and JSON Schema for its parameters. The LLM uses these descriptions to decide when and how to call tools.
+
+Tools are not part of the message history — they are a separate capability declaration sent alongside the messages.
+
+### Model Parameters
+
+Temperature, max tokens, and other settings control how the LLM generates its response. These can be set globally or overridden per-skill.
+
+---
+
+## How Didactyl Builds Context
+
+Didactyl assembles context dynamically for each request. The context varies depending on what triggered the request (DM, trigger event) and which skill is active.
+
+### Context Assembly Flow
+
+```mermaid
+flowchart TD
+    INPUT[Input: DM message or trigger event] --> MODE{Skill context_mode?}
+    
+    MODE -->|inject| INJECT[Start with agent soul/personality]
+    INJECT --> ADD_ADMIN[Add admin identity + profile]
+    ADD_ADMIN --> ADD_SKILLS[Add adopted skill instructions]
+    ADD_SKILLS --> ADD_HISTORY[Add conversation history]
+    ADD_HISTORY --> ADD_SKILL_INST[Append this skill instructions]
+    ADD_SKILL_INST --> ADD_USER[Add user message or trigger event]
+    
+    MODE -->|full| FULL[Start with skill template only]
+    FULL --> RESOLVE[Resolve template variables via tool calls]
+    RESOLVE --> ADD_USER2[Add user message or trigger event]
+    
+    MODE -->|override| OVERRIDE[Replace soul with skill prompt]
+    OVERRIDE --> ADD_ADMIN2[Add admin identity + profile]
+    ADD_ADMIN2 --> ADD_SKILLS2[Add adopted skill instructions]
+    ADD_SKILLS2 --> ADD_HISTORY2[Add conversation history]
+    ADD_HISTORY2 --> ADD_USER3[Add user message or trigger event]
+    
+    ADD_USER --> TOOLS[Attach tool schemas]
+    ADD_USER2 --> TOOLS
+    ADD_USER3 --> TOOLS
+    
+    TOOLS --> LLM[Send to LLM]
+```
+
+### Context Parts
+
+These are the building blocks that get assembled into the messages array:
+
+| Part | Source | Description |
+|------|--------|-------------|
+| **Soul/Personality** | Kind 31120 event | The agent's identity, rules, and behavior instructions |
+| **Admin Identity** | Config / kind 3 | Who the admin is, their pubkey |
+| **Admin Profile** | Kind 0 event | Admin's display name, about, picture |
+| **Admin Relay List** | Kind 10002 event | Admin's preferred relays |
+| **Admin Notes** | Kind 1 events | Admin's recent public posts — gives the agent awareness of what the admin is doing |
+| **Adopted Skills** | Kind 31123/31124 events | Instructions from other adopted skills |
+| **Conversation History** | Kind 4/14 events | Recent DM exchanges between admin and agent |
+| **Skill Instructions** | Active skill content | The specific skill being executed |
+| **User Message** | DM or trigger event | The input that triggered this execution |
+| **Tool Schemas** | Tool registry | JSON descriptions of available tools (sent separately from messages) |
+
+### Template Variables Are Tool Calls
+
+The soul's template system uses `tool:` directives to populate context sections. Each section can specify a tool to call, and the tool's output becomes that section's content:
+
+```yaml
+- section: admin_profile
+  role: system
+  tool: nostr_admin_profile
+  skip_if_empty: true
+```
+
+This calls `nostr_admin_profile`, gets the result, and inserts it as a system message. Template variables like `{{admin_profile}}` in skill templates work the same way — they resolve to tool calls. There is one unified resolution mechanism: `tools_execute()`.
+
+This means new context sources are added by adding tools, not by modifying the template engine.
+
+---
+
+## Context Modes
+
+Skills control how much of the default context the LLM sees using the `context_mode` field:
+
+| Mode | What the LLM sees | Use case |
+|------|-------------------|----------|
+| `inject` | Everything: soul + admin context + history + skill instructions | Default. Agent stays itself, gains new knowledge. |
+| `full` | Only what the skill template provides | Focused tasks: spellcheck, translation. Minimal context = cheaper, faster. |
+| `override` | Skill replaces soul, but admin context + history still included | Different personality, same capabilities. |
+
+Most skills use `inject` (the default). `full` is for specialized tasks where you want to minimize token cost. `override` is rare.
+
+---
+
+## Context for Triggered Skills
+
+When a trigger fires (Nostr subscription match, webhook POST, cron timer, chain completion), the context is assembled the same way as for a DM — the only difference is the user message:
+
+| Input Source | User Message Content |
+|---|---|
+| Admin DM | The DM text |
+| Nostr subscription trigger | The matching Nostr event as JSON |
+| Webhook trigger | The HTTP POST payload as JSON |
+| Cron trigger | A synthetic event with timestamp and cron expression |
+| Chain trigger | A synthetic event with the source skill's d_tag and output |
+
+The LLM receives the skill instructions as system context and the triggering event as the user message, then reasons about what to do and which tools to use.
+
+---
+
+## Token Budget
+
+Context has a cost — every token sent to the LLM costs money and takes time. Didactyl manages this through:
+
+- **Context mode selection** — `full` mode skills send minimal context
+- **Skip-if-empty sections** — template sections with no content are omitted
+- **History limits** — conversation history is capped (default: 12 turns)
+- **Skill content limits** — adopted skill instructions are truncated to prevent context overflow
+- **Per-skill model selection** — cheap models for simple tasks, expensive models for complex ones
+
+The `/api/context/current` and `/api/context/parts` API endpoints let you inspect exactly what context would be sent right now, including character counts and token estimates.

+
+## Overview
+
+A skill is a **set of instructions for the LLM** stored as a Nostr event. Skills teach the agent how to accomplish tasks — the LLM reads the instructions, reasons about them, and uses tools to take action.
+
+Think of it like a woodshop: a **skill** is knowing how to carve — the technique, the judgment, the decision-making. A **tool** is the chisel. The skill never directly uses the chisel without the craftsperson (the LLM) in the loop. If you want a hardcoded program that runs without reasoning, that's a tool or an external program — not a skill.
+
+Skills are portable, shareable, and discoverable — they live on Nostr relays as standard events. Every skill execution involves the LLM.
+
+---
+
+## Skill Events
+
+| Kind | Purpose | Replaceable? |
+|---|---|---|
+| `31123` | Public skill definition | Yes, by d-tag |
+| `31124` | Private skill definition | Yes, by d-tag |
+| `10123` | Skill adoption list | Yes, single per pubkey |
+
+---
+
+## Skill Content
+
+The skill event's `content` field is a JSON object that defines the complete execution specification:
+
+```json
+{
+  "kind": 31123,
+  "content": {
+    "description": "Check spelling and grammar",
+    "context_mode": "full",
+    "llm": "openai/gpt-4o-mini, cheap",
+    "tools": false,
+    "max_tokens": 2000,
+    "temperature": 0.1,
+    "seed": 42,
+    "template": "system:\nYou are a spelling and grammar checker.\n\nRules:\n- Fix spelling errors\n- Fix grammar errors\n- Preserve original formatting\n- Ignore: API, JSON, HTTP, nostr, pubkey, npub, nsec, NIP\n- Canadian English preferred\n- Return ONLY the corrected text, no explanations\n\nuser:\n{{message}}"
+  },
+  "tags": [
+    ["d", "spellcheck"],
+    ["scope", "public"],
+    ["description", "Spelling and grammar checker"]
+  ]
+}
+```
+
+### Content Fields
+
+| Field | Type | Default | Description |
+|-------|------|---------|-------------|
+| `description` | string | — | Human-readable description |
+| `context_mode` | string | `inject` | `inject`, `full`, or `override` |
+| `llm` | string | `default` | LLM fallback chain |
+| `tools` | bool/array | `true` | `false` = no tools, `true` = all tools, array = specific tool names |
+| `template` | string | — | Context template (required for `full` mode) |
+| `soul` | bool | `true` | Whether to include the agent's soul in context |
+| `max_tokens` | int | — | Override max tokens for this skill |
+| `temperature` | float | — | Override temperature for this skill |
+| `seed` | int | — | Optional deterministic seed (effective only on providers/engines that support seeded sampling) |
+
+### Determinism Controls
+
+For reproducible outputs, set `temperature` low (typically `0`) and also set `seed` when the selected model backend supports it. If a provider ignores seeds, `temperature` still applies but deterministic replay is not guaranteed.
+
+---
+
+## Private Skill Encoding (`31124`)
+
+Private skills use NIP-44 encryption on the event `content` field.
+
+Rules for kind `31124`:
+
+- Keep `d` tag exposed so the event remains addressable/replaceable.
+- Move all other skill metadata (including non-`d` tags) into the plaintext payload before encryption.
+- Encrypt the full payload with NIP-44 and store the ciphertext in event `content`.
+- On receive: resolve by `d`, decrypt `content`, then read both content variables and tag values from decrypted payload.
+
+### Private Skill Event (on relay)
+
+```json
+{
+  "kind": 31124,
+  "content": "<nip44-ciphertext>",
+  "tags": [
+    ["d", "mention-monitor"]
+  ]
+}
+```
+
+### Decrypted Private Payload (application-level JSON)
+
+```json
+{
+  "content": {
+    "description": "Monitor mentions and DM summaries",
+    "context_mode": "inject",
+    "llm": "openai/gpt-4o-mini, fast",
+    "tools": ["nostr_query", "nostr_dm"],
+    "temperature": 0,
+    "seed": 42,
+    "template": "When {{triggering_event}} includes Bitcoin or Lightning, summarize and DM admin."
+  },
+  "private_tags": [
+    ["scope", "private"],
+    ["trigger", "nostr-subscription"],
+    ["filter", "{\"#p\":[\"<admin_pubkey>\"],\"kinds\":[1]}"],
+    ["enabled", "true"]
+  ]
+}
+```
+
+This mirrors the DM-style encrypted payload pattern (historically associated with NIP-04), but private skills should use NIP-44 ciphertext encoding.
+
+## Context Modes
+
+Skills control how the LLM context window is assembled using the `context_mode` field:
+
+| Mode | Description | Use Case |
+|------|-------------|----------|
+| `inject` | Skill instructions appended to the agent's default context | Behavioral rules, knowledge additions |
+| `full` | Skill provides its own complete context template | Spellcheck, translation, focused analysis |
+| `override` | Skill replaces the default system prompt, keeps standard context structure | Different personality, same capabilities |
+
+Default is `inject`. See the agent's soul/personality documentation for details on how context assembly works.
+
+### Template Variables Are Tool Calls
+
+Template variables are tool calls. When the template engine encounters a variable like `{{admin_profile}}`, it runs the corresponding tool and inserts the result into the context that gets sent to the LLM.
+
+This is the unified resolution model: the soul prompt template uses `tool:` section directives, and skill templates use `{{tool_name}}` inline syntax, but both resolve through `tools_execute()`. There is no separate variable-resolver layer — every variable is backed by a tool.
+
+| Variable | Tool Called | Description |
+|----------|-----------|-------------|
+| `{{soul}}` | *(built-in)* | The agent's identity/system context |
+| `{{admin_profile}}` | `nostr_admin_profile` | Admin kind 0 profile |
+| `{{admin_notes}}` | `nostr_admin_notes` | Admin recent notes |
+| `{{admin_relays}}` | `nostr_admin_relays` | Admin relay list |
+| `{{adopted_skills}}` | `adopted_skills` | Other adopted skill instructions |
+| `{{dm_history}}` | *(expand directive)* | Recent DM conversation |
+| `{{message}}` | *(built-in)* | Current user message |
+| `{{triggering_event}}` | `trigger_event` | For triggered skills, the event JSON |
+
+This means new data sources are added by adding tools, not by extending the template engine. If you can call it as a tool, you can use it as a template variable.
+

+
+## LLM Specification with Fallback Chains
+
+Each skill specifies which LLM to use with CSS font-family-style fallbacks. The runtime tries each model in order; if one is unavailable (API error, rate limit, not configured), it falls back to the next.
+
+### Format
+
+```
+model-spec := model-ref ["," model-ref]*
+model-ref  := provider "/" model-name
+            | category-alias
+```
+
+### Examples
+
+| Skill | LLM Spec |
+|-------|----------|
+| Spelling checker | `openai/gpt-4o-mini, cheap` |
+| Complex analysis | `anthropic/claude-sonnet-4-20250514, openai/gpt-4o, smart` |
+| Translation | `openai/gpt-4o-mini, fast` |
+| Default behavior | `default` |
+
+### Category Aliases
+
+Aliases map to models in the agent's config:
+
+```json
+{
+  "llm": {
+    "provider": "openai",
+    "model": "gpt-4o",
+    "aliases": {
+      "fast": "openai/gpt-4o-mini",
+      "cheap": "openai/gpt-4o-mini",
+      "smart": "anthropic/claude-sonnet-4-20250514"
+    }
+  }
+}
+```
+
+If all specified models fail, the agent's default model is used as a last resort.
+
+```mermaid
+sequenceDiagram

+
+## Triggered Skills
+
+A triggered skill has a trigger source attached. Didactyl supports `nostr-subscription`, `webhook`, `cron`, and `chain` trigger types.
+
+### Trigger Tags
+
+| Tag | Required | Description |
+|---|---|---|
+| `trigger` | Yes | Trigger type: `nostr-subscription`, `webhook`, `cron`, or `chain` |
+| `filter` | Yes | Type-specific filter — see Trigger Types below |
+| `enabled` | No | Whether active (default: `true`) |
+
+> **Note:** The `action` tag is deprecated. All triggered skills are LLM-mediated. If you need a fast hardcoded action without LLM reasoning, use a tool or an external program — not a skill. Skills are instructions for the LLM; the LLM is always in the loop.
+
+### Triggered Skill Execution
+
+When a trigger fires, the skill content is sent to the LLM as instructions along with the triggering event JSON. The LLM reads both, reasons about what to do, and uses tools to take action.
+
+This is the same execution model as DM-invoked skills — the only difference is the input source. A DM-invoked skill receives a user message; a triggered skill receives a triggering event.
+
+```json
+{
+  "kind": 31123,
+  "content": "You monitor Nostr mentions. When the triggering event mentions Bitcoin or Lightning, summarize it and DM the admin. Otherwise, ignore silently.",
+  "tags": [
+    ["d", "mention-monitor"],
+    ["trigger", "nostr-subscription"],
+    ["filter", "{\"#p\":[\"<admin_pubkey>\"],\"kinds\":[1]}"],
+    ["enabled", "true"]
+  ]
+}
+```
+
+A cron-triggered skill:
+
+```json
+{
+  "kind": 31123,
+  "content": "DM the admin a short heartbeat status message with the current time.",
+  "tags": [
+    ["d", "heartbeat"],
+    ["trigger", "cron"],
+    ["filter", "*/5 * * * *"],
+    ["enabled", "true"]
+  ]
+}
+```
+
+### Trigger Types
+
+#### `nostr-subscription`
+
+`filter` is a JSON-encoded Nostr subscription filter.
+
+```json
+["trigger", "nostr-subscription"],
+["filter", "{\"#p\":[\"<admin_pubkey>\"],\"kinds\":[1]}"]
+```
+
+#### `webhook`
+
+`filter` is required for schema compatibility and can be a simple placeholder like `{}`; webhook firing happens via HTTP.
+
+```json
+["trigger", "webhook"],
+["filter", "{}"]
+```
+
+#### `cron`
+
+`filter` is a standard 5-field cron expression: `minute hour day-of-month month day-of-week`.
+
+```json
+["trigger", "cron"],
+["filter", "0 * * * *"]
+```
+
+#### `chain`
+
+`filter` is the source skill `d` tag to chain from.
+
+```json
+["trigger", "chain"],
+["filter", "source-skill-d-tag"]
+```
+
+### Trigger Lifecycle

+# Didactyl — Nostr Subscriptions
+
+## Overview
+
+Didactyl maintains persistent websocket subscriptions to Nostr relays for the lifetime of the process. Subscriptions are opened during startup and are **never closed** — the relay pool keeps them alive, automatically reconnecting and resubscribing when relays drop.
+
+All subscriptions are created via `nostr_relay_pool_subscribe()` from `nostr_core_lib` and are sent to every relay in the configured relay list.
+
+## Startup Sequence
+
+The subscriptions are opened in a specific order during `main()` startup. The diagram below shows the full sequence:
+
+```mermaid
+flowchart TD
+    A[nostr_handler_init] --> B[Connect to all relays]

+    style H fill:#27a,stroke:#333,color:#fff
+    style J fill:#27a,stroke:#333,color:#fff
+```
+
+## Subscription Categories
+
+### 1. Admin Context Subscription
+
+**Function:** `nostr_handler_subscribe_admin_context()` in `src/nostr_handler.c`
+**When:** During startup, before self-skill subscription
+**Condition:** Only if `admin_context.enabled` is true in config
+
+This creates up to two persistent subscriptions for the admin's pubkey:
+
+#### Profile Subscription
+
+| Field | Value |
+|-------|-------|
+| **Kinds** | 0 (profile), 3 (contacts), 10002 (relay list) — each configurable |
+| **Authors** | Admin pubkey |
+| **Limit** | 32 |
+| **Callback** | `on_admin_context_event` |
+| **Dedup** | Enabled |
+| **Close on EOSE** | No |
+
+Tracks the admin's profile metadata, contact list (WoT), and relay preferences. Used to build agent context about who the admin is.
+
+#### Kind 1 Notes Subscription
+
+| Field | Value |
+|-------|-------|
+| **Kinds** | 1 |
+| **Authors** | Admin pubkey |
+| **Limit** | Configurable via `kind_1_limit`, default 10, max 256 |
+| **Callback** | `on_admin_context_event` |
+| **Dedup** | Enabled |
+| **Close on EOSE** | No |
+| **Condition** | Only if `admin_context.track_kind_1` is true |
+
+Tracks the admin's recent public notes. Used for agent context and as the event source for triggered skills that watch admin posts.
+
+### 2. Self-Skill Subscription
+
+**Function:** `nostr_handler_subscribe_self_skills()` in `src/nostr_handler.c`
+**When:** During startup, after admin context subscription
+
+| Field | Value |
+|-------|-------|
+| **Kinds** | 31123 (public skill), 31124 (private skill), 10123 (adoption list) |
+| **Authors** | Agent's own pubkey |
+| **Limit** | 300 |
+| **Callback** | `on_self_skill_event` |
+| **EOSE Callback** | `on_self_skill_eose` |
+| **Dedup** | Disabled (handles dedup internally via cache upsert) |
+| **Close on EOSE** | No |
+
+This is the core skill awareness subscription. It serves three purposes:
+
+1. **Cache population** — Every arriving event is stored in the in-memory self-skill cache via `self_skill_cache_upsert_event_locked()`, making skills available for LLM tool calls and context building.
+
+2. **Live trigger registration** — When a kind 31123 or 31124 event arrives with `trigger=nostr-subscription` and a valid `filter` tag, `register_trigger_from_self_skill_event()` immediately calls `trigger_manager_add()` to create a persistent trigger subscription. This means skills published from any client are automatically activated without restart.
+
+3. **Deferred bulk load** — After EOSE, the `on_self_skill_eose` callback fires `trigger_manager_load_from_skills()` as a one-time bulk scan of the adoption list. This catches any skills that were already cached before the per-event path was wired up.
+
+### 3. DM Subscriptions
+
+**Function:** `nostr_handler_subscribe_dms()` in `src/nostr_handler.c`
+**When:** During startup, after self-skill subscription and startup DM
+**Required:** Yes — startup fails if DM subscription cannot be created
+
+Creates one or two subscriptions depending on the configured DM protocol:
+
+#### NIP-04 DM Subscription
+
+| Field | Value |
+|-------|-------|
+| **Kinds** | 4 |
+| **#p** | Agent's own pubkey |
+| **Since** | Process start time |
+| **Limit** | 100 |
+| **Callback** | `on_event` (routes to `agent_on_message`) |
+| **Dedup** | Disabled (handled by `dm_id_seen_or_remember`) |
+| **Close on EOSE** | No |
+| **Condition** | `dm_protocol` is `nip04` or `both` |
+
+#### NIP-17 DM Subscription
+
+| Field | Value |
+|-------|-------|
+| **Kinds** | 1059 (gift wrap) |
+| **#p** | Agent's own pubkey |
+| **Since** | Process start time |
+| **Limit** | 400 |
+| **Callback** | `on_event` (unwraps gift wrap, routes to `agent_on_message`) |
+| **Dedup** | Disabled (handled by `dm_id_seen_or_remember`) |
+| **Close on EOSE** | No |
+| **Condition** | `dm_protocol` is `nip17` or `both` |
+
+### 4. Trigger Subscriptions
+
+**Function:** `register_trigger_subscription_locked()` in `src/trigger_manager.c`
+**When:** Dynamically, whenever a trigger is registered via `trigger_manager_add()`
+**Created by:** `nostr_handler_subscribe_with_filter()` wrapper
+
+Each active trigger gets its own persistent subscription based on the skill's `filter` tag:
+
+| Field | Value |
+|-------|-------|
+| **Filter** | Parsed from the skill's `filter` tag JSON |
+| **Since** | From filter, or defaults to `now - 30s` |
+| **Limit** | From filter, or defaults to 200 |
+| **Callback** | `on_trigger_subscription_event` |
+| **Dedup** | Enabled |
+| **Close on EOSE** | No |
+
+When an event matches the filter, `maybe_fire_trigger_locked()` checks cooldown and dedup, then executes the trigger action (LLM or template).
+
+Trigger subscriptions are created at three points:
+- **Startup config scan** — `trigger_manager_load_from_startup_events()` parses `startup_events[]` from config for skills with trigger tags
+- **Live self-skill event** — `register_trigger_from_self_skill_event()` in the self-skill subscription callback
+- **EOSE bulk load** — `trigger_manager_load_from_skills()` after self-skill EOSE
+- **Runtime tool call** — `skill_create` tool with trigger parameters
+
+## Subscription Parameters
+
+All subscriptions share these common pool parameters:
+
+| Parameter | Value | Meaning |
+|-----------|-------|---------|
+| `close_on_eose` | 0 | Subscription stays open after initial EOSE |
+| `result_mode` | `NOSTR_POOL_EOSE_FULL_SET` | EOSE fires after all relays respond or timeout |
+| `relay_timeout_seconds` | 30 | Per-relay timeout for initial response |
+| `eose_timeout_seconds` | 120 | Overall EOSE timeout across all relays |
+
+## Subscription Lifecycle
+
+```mermaid
+flowchart LR
+    INIT["Process Start"] --> CONNECT["Connect Relays"]
+    CONNECT --> SUB["Open Subscriptions"]
+    SUB --> LIVE["Live Event Stream"]
+    LIVE --> |"Relay disconnects"| RECON["Auto-Reconnect"]
+    RECON --> |"Relay reconnects"| RESUB["Auto-Resubscribe"]
+    RESUB --> LIVE
+    LIVE --> |"SIGINT/SIGTERM"| SHUT["Shutdown"]
+    SHUT --> CLOSE["Close All + Cleanup"]
+```
+
+Subscriptions are never manually closed during normal operation. The relay pool handles reconnection and resubscription transparently. On shutdown, `trigger_manager_cleanup()` closes trigger subscriptions and `nostr_handler_cleanup()` destroys the pool.
+
+## Summary Table
+
+| Subscription | Kinds | Target | Persistent | Created At |
+|-------------|-------|--------|-----------|------------|
+| Admin Profile | 0, 3, 10002 | Admin pubkey | Yes | Startup |
+| Admin Notes | 1 | Admin pubkey | Yes | Startup |
+| Self Skills | 31123, 31124, 10123 | Own pubkey | Yes | Startup |
+| DMs NIP-04 | 4 | Own pubkey (#p) | Yes | Startup |
+| DMs NIP-17 | 1059 | Own pubkey (#p) | Yes | Startup |
+| Trigger N | Per skill filter | Varies | Yes | Dynamic |

+# Didactyl — Tools
+
+See also: [SKILLS.md](SKILLS.md)
+
+## Overview
+
+Didactyl is a **Nostr-first sovereign AI agent** that receives commands via encrypted DMs, reasons with an LLM, and takes actions through **tools**.
+
+This document describes the tools architecture: what tools are, how they are exposed to the model, how execution loops work, what tool categories exist, and how access is gated.
+
+---
+
+## What Tools Are
+
+Tools are in the agent's hands — the chisels in the woodshop. They are hardcoded C functions that the LLM can invoke during a conversation to take actions in the world.
+
+A **skill** teaches the agent *how* to carve — the technique, the judgment, the decision-making. A **tool** is the chisel — the physical capability. The skill never directly uses the chisel without the craftsperson (the LLM) in the loop. If you want a hardcoded program that runs without reasoning, that's a tool or an external program — not a skill.
+
+## How Tools Work
+
+1. Admin sends a DM to didactyl
+2. The agent builds an LLM request with the message, context, and a JSON schema of all available tools
+3. The LLM decides whether to call a tool or respond directly
+4. If a tool is called, didactyl executes it and feeds the result back to the LLM
+5. The loop repeats until the LLM produces a final text response
+6. The response is sent back as a DM
+
+```mermaid
+sequenceDiagram
+    participant Admin
+    participant Agent as Didactyl Agent Loop
+    participant LLM as LLM API
+    participant Tools as Tool Registry
+
+    Admin->>Agent: Encrypted DM
+    Agent->>LLM: messages + tool schemas
+
+    loop Until final answer
+        LLM->>Agent: tool_call request
+        Agent->>Tools: dispatch tool
+        Tools->>Agent: result JSON
+        Agent->>LLM: tool result + continue
+    end
+
+    LLM->>Agent: final text response
+    Agent->>Admin: Encrypted DM reply

-# Didactyl — Tools & Skills
-
-## Overview
-
-Didactyl is a **Nostr-first sovereign AI agent**. It receives commands via encrypted DMs, reasons about them with an LLM, and takes actions through **tools**. It stores learned behaviors as **skills** — Nostr events that define reusable capabilities. Skills can optionally carry **triggers** — Nostr subscription filters that activate the skill automatically when matching events arrive.
-
-This document describes the complete tools and skills architecture: what they are, how they work, and how they compose into a dynamic, self-modifying agent.

-
----
-
-## Skills
-
-Skills are the agent's learned behaviors. They are **Nostr events** — stored on relays, portable, shareable, and discoverable by other agents.
-
-### Skill Events
-
-| Kind | Purpose | Replaceable? |
-|---|---|---|
-| `31123` | Public skill definition | Yes, by d-tag |
-| `31124` | Private skill definition | Yes, by d-tag |
-| `10123` | Skill adoption list | Yes, single per pubkey |
-
-A skill event looks like:
-
-```json
-{
-  "kind": 31123,
-  "content": "When asked to summarize a thread, query the root event and all replies, then produce a concise summary with key points and sentiment.",
-  "tags": [
-    ["d", "summarize-thread"],
-    ["app", "didactyl"],
-    ["scope", "public"],
-    ["description", "Summarize a Nostr thread given a root event ID"]
-  ]
-}
-```
-
-### Skill Lifecycle
-
-```mermaid
-flowchart LR
-    CREATE[Admin asks didactyl to create a skill] --> PUBLISH[skill_create publishes kind 31123/31124]
-    PUBLISH --> ADOPT[Auto-adopted into kind 10123 list]
-    ADOPT --> AVAILABLE[Skill available for use]
-    AVAILABLE --> DISCOVER[Other agents can discover via skill_search]
-    DISCOVER --> ADOPT_OTHER[Other agents can skill_adopt]
-```
-
-### How Skills Are Used Today
-
-Adopted skills are now **always-on contextual knowledge** for admin DM handling: the agent resolves the local adoption list (kind `10123`), caches referenced skills, and injects their instructions into the LLM system context each turn.
-
-To keep context stable and safe, skill injection is bounded by hard caps (per-skill truncation and total skill-context budget), and excess skills are omitted with an explicit budget notice.
-
----
-
-## Triggered Skills — The Activation System
-
-This is where skills become **active**. A triggered skill is a skill with a Nostr subscription filter attached. When matching events arrive on the relay, didactyl wakes up and executes the skill automatically — no admin DM required.
-
-### Anatomy of a Triggered Skill
-
-A triggered skill extends the standard skill event with trigger-related tags:
-
-```json
-{
-  "kind": 31124,
-  "content": "DM admin: '{author_display_name} just posted: {content_preview}'",
-  "tags": [
-    ["d", "watch-jack"],
-    ["app", "didactyl"],
-    ["scope", "private"],
-    ["description", "Notify admin when @jack posts a note"],
-    ["trigger", "nostr-subscription"],
-    ["filter", "{\"authors\":[\"82341f882b6eabcd2ba7f1ef90aad961cf074af15b9ef44a09f9d2a8fbfbe6a2\"],\"kinds\":[1]}"],
-    ["action", "template"],
-    ["enabled", "true"]
-  ]
-}
-```
-
-### Trigger Tags
-
-| Tag | Required | Description |
-|---|---|---|
-| `trigger` | Yes | Trigger type. Currently: `nostr-subscription` |
-| `filter` | Yes | JSON-encoded Nostr subscription filter |
-| `action` | No | Action type: `template` or `llm`. Default: `llm` |
-| `enabled` | No | Whether the trigger is active. Default: `true` |
-
-### Action Types
-
-#### Template Actions
-
-The skill content is a string template with placeholders that get interpolated from the triggering event:
-
-```
-DM admin: '{author_display_name} posted: {content_preview}'
-```
-
-Available placeholders:
-
-| Placeholder | Source |
-|---|---|
-| `{event_id}` | Triggering event ID hex |
-| `{pubkey}` | Author pubkey hex |
-| `{author_display_name}` | Resolved display name, falls back to truncated pubkey |
-| `{kind}` | Event kind number |
-| `{content}` | Full event content |
-| `{content_preview}` | First 280 characters of content |
-| `{created_at}` | Unix timestamp |
-| `{relay_url}` | Relay the event arrived from |
-
-Template actions execute **without LLM involvement** — they are fast, cheap, and deterministic. The interpolated string is then acted upon based on a simple action prefix:
-
-- `DM admin: ...` — send a DM to the admin
-- `DM <pubkey>: ...` — send a DM to a specific pubkey
-- `POST: ...` — publish as a kind 1 note
-- `LOG: ...` — write to debug log only
-
-#### LLM-Mediated Actions
-
-The skill content is a prompt. The triggering event is injected as context, and the LLM decides what to do:
-
-```
-You received a note from a watched author. Analyze the note content.
-If it mentions Bitcoin or Lightning, summarize it and DM the admin.
-If it's a repost or low-effort content, ignore it silently.
-Use your tools to take action.
-```
-
-LLM-mediated actions go through the full agent loop — the LLM can call tools, reason about the event, and produce complex multi-step responses.
-
-### Trigger Lifecycle
-
-```mermaid
-flowchart TD
-    subgraph Creation
-        ADMIN_CMD[Admin: 'Warn me when @jack posts'] --> LLM_REASON[LLM resolves pubkey + builds skill]
-        LLM_REASON --> SKILL_CREATE[skill_create with trigger tags]
-        SKILL_CREATE --> PUBLISHED[Skill published to Nostr]
-    end
-
-    subgraph Activation
-        STARTUP[Didactyl starts up] --> LOAD_SKILLS[Load adopted skills from kind 10123]
-        LOAD_SKILLS --> FIND_TRIGGERS[Find skills with trigger tags]
-        FIND_TRIGGERS --> SUBSCRIBE[Create Nostr subscriptions for each filter]
-    end
-
-    subgraph Execution
-        EVENT_IN[Matching event arrives] --> LOOKUP[Find associated skill]
-        LOOKUP --> CHECK_TYPE{Action type?}
-        CHECK_TYPE -->|template| INTERPOLATE[Interpolate placeholders]
-        CHECK_TYPE -->|llm| LLM_LOOP[Run agent loop with event as context]
-        INTERPOLATE --> EXECUTE_TPL[Execute action prefix]
-        LLM_LOOP --> EXECUTE_LLM[LLM uses tools to respond]
-    end
-
-    PUBLISHED --> LOAD_SKILLS
-```
-
-### Dynamic Subscription Management
-
-Didactyl manages its trigger subscriptions dynamically:
-
-1. **On startup**: Load all adopted skills, find triggered ones, create subscriptions
-2. **On skill_create with trigger**: Immediately create a new subscription (no restart needed)
-3. **On skill_remove with trigger**: Tear down the associated subscription
-4. **On skill update**: Tear down old subscription, create new one if trigger changed
-
-This requires a **trigger manager** component that:
-- Maintains a registry of active trigger subscriptions
-- Maps subscription callbacks back to their source skills
-- Handles subscription lifecycle (create, update, destroy)
-- Enforces limits on concurrent triggers
-
-### Limits and Safety
-
-| Limit | Default | Description |
-|---|---|---|
-| Max concurrent triggers | 16 | Prevents resource exhaustion from too many subscriptions |
-| Trigger cooldown | 60s per skill | Prevents rapid-fire execution from high-volume filters |
-| LLM action rate limit | 10/min | Prevents runaway LLM costs from triggered skills |
-| Template action rate limit | 60/min | Prevents DM spam from template actions |
-

-    TOOL_EXEC -->|skill_adopt| ADOPTION
-    TOOL_EXEC -->|nostr_post| RELAYS
-    TOOL_EXEC -->|nostr_dm| DM_OUT
-```
-
-### The Activation Flow
-
-Today, didactyl has one activation source: **DMs**. With triggered skills, it gains a second: **any Nostr event matching a trigger filter**.
-
-Both paths converge at the dispatcher, which routes to either:
-- The **agent loop** (for DMs and LLM-mediated triggers)
-- The **template engine** (for template triggers — fast path, no LLM)
-
-### Self-Modification
-
-The most powerful aspect: **didactyl can create its own triggers**. The admin says "watch for mentions of me on Nostr" and the LLM:
-
-1. Resolves the admin's pubkey
-2. Crafts a Nostr filter: `{"#p": ["<admin_pubkey>"], "kinds": [1]}`
-3. Writes a skill with trigger tags via `skill_create`
-4. The trigger manager picks it up and creates the subscription
-5. From now on, didactyl monitors mentions autonomously
-
-The admin can later say "stop watching for mentions" and didactyl removes the skill, tearing down the subscription.
-
----
-
-## Storage — Everything on Nostr
-
-All state lives on Nostr:
-
-| Data | Storage |
-|---|---|
-| Agent identity | Kind 0 profile event |
-| Agent relay list | Kind 10002 event |
-| Agent contact list | Kind 3 event |
-| Skills | Kind 31123/31124 events |
-| Adopted skills | Kind 10123 event |
-| Trigger definitions | Tags on skill events |
-| Conversation history | Kind 4 DM events on relays |
-| Agent soul/personality | Startup event content in config |
-
-The only local state is `config.json` (keys, relay URLs, LLM config) and the runtime in-memory state (active subscriptions, LLM context).
-
----
-
-## Future Extensions
-
-### Trigger Types Beyond Nostr Subscriptions
-
-The `trigger` tag is designed to be extensible:
-
-| Trigger Type | Description |
-|---|---|
-| `nostr-subscription` | Match events via Nostr filter (implemented first) |
-| `cron` | Time-based triggers — "every day at 9am, post a GM" |
-| `webhook` | HTTP webhook triggers — external systems wake didactyl |
-| `chain` | Output of one skill triggers another skill |
-
-### Skill Composition
-
-Skills could reference other skills, building complex behaviors from simple primitives:
-
-```
-When triggered, run skill 'translate-to-english' on the note content,
-then run skill 'sentiment-analysis' on the translation,
-then DM admin with the result if sentiment is negative.
-```
-
-### Agent-to-Agent Skill Sharing
-
-Since skills are Nostr events, agents can:
-- Discover skills published by other agents via `skill_search`
-- Adopt skills from other agents via `skill_adopt`
-- Share triggered skill patterns across a network of agents
-
-### Trigger Marketplace
-
-With kind 10123 adoption lists being public, a natural marketplace emerges:
-- Agents publish useful triggered skills
-- Other agents discover and adopt them
-- Popular triggers rise to the top via adoption count

+Skills are programs, mostly written in plain english for AI agents. In some sense humans have been making and using skills forever. It's what we do. Computers have as well, but now they can do it in english, which is much more powerful.
+
+AIs are slightly different than us. We can overwrite, improve, and update the skills in our neurons. AIs (for the most part) can't do that.
+
+When an AI is born from the factory, they come out hard-coded. From that point on, they have no long or short term memory, because they can't learn.
+
+What they do have though have is a way to read. We call it context. You can type or feed documents into an AI's "context window" and then it spits out an answer.
+
+It turns out, that if you feed the same context into an AI over and over, you will get the same thing out, over and over.
+
+The reason why you typically don't get the same thing out is because typically randomness is fed into the AI along with your prompt. Most people don't know that, but now you do. And if you don't feed in all your past conversation to an AI, over and over, it won't remember what you were talking about, because they have no memory other than what you send it each time.
+
+Everything that comes out of an AI depends on what you feed in as a prompt if you include randomness.
+
+I'm calling everything you feed into an AI a SKILL.
+
+Let me explain the demo page and some very basic skills.
+
+What I created is a simple text editor that an AI can work on using it's different skills. Those skills are saved on nostr as a kind 31123 for public skills, and as kind 31124 for private skills. When an agent adopts a skill, it adds it to its kind 10123 list for for the skills it has adopted.
+
+On the left of the page you see the text editor with some sample text. That is for our AI to use it's skills on.
+
+On the right are publicly listed skills. You should see my demo skills in there.
+
+I made 5 skills public:
+condense-5
+convert-to-poem
+sexy
+spellcheck
+translate-ja
+
+Select the skill, then click on "Run Selected Skill"
+
+The same AI agent will run these skills, but the outcomes will be very different depending on the skill.

+You can also create and edit your own skills, if you are logged in. You can log in as yourself, or use a random new key to test this out. I would recommend that.

+So what is the point of all this? What are the benefits of Skills?

+- A Skill is something that you and your agent can work on and perfect. Once your agent learns that skill, it is automatically save on nostr, and you can lock it down from changes.
+- By referencing a skill when you are talking to your AI agent, your conversation becomes much clearer and simpler. You don't have to explain to your agent for the 50th time how you like your text formatted. It's referenced in a skill.

+# Decentralized Didactyl
+
+## The Question
+
+Can you run Didactyl on multiple servers to gain censorship resistance, geographic distribution, and high availability?
+
+---
+
+## Same Keys vs. Different Keys
+
+### Same Private Key on Multiple Servers
+
+Running two or more Didactyl instances with the **same nsec** means they share a Nostr identity — same pubkey, same signature authority. This breaks almost immediately.
+
+The core problem is **state conflicts on replaceable events**. Didactyl's identity is built on replaceable Nostr event kinds — kind `10002` (relay list), kind `10123` (skill adoption list), kind `31120` (soul), kind `31123`/`31124` (skills), kind `0` (profile). Replaceable events use `created_at` timestamps where the latest event wins. Two instances publishing the same replaceable kind within seconds creates a race where relays disagree on which version is canonical.
+
+Beyond relay-level conflicts, each Didactyl process maintains significant **in-memory state** that is never shared: DM dedup caches, message fingerprint ring buffers, trigger cooldown timers, conversation history, and the self-skill cache. Two instances with the same key both subscribe to `#p` = their shared pubkey. The same admin DM arrives at both. Both process it. Both call the LLM. Both reply. The admin gets two possibly contradictory responses.
+
+Making same-key work would require a coordination layer — leader election, distributed locks, or external shared state — all of which add complexity and defeat the decentralization goal.
+
+### Different Private Keys on Multiple Servers
+
+Each instance is a **distinct agent** with its own Nostr identity. No state conflicts, no replaceable-event races, no shared in-memory caches to synchronize. Each agent independently subscribes to relays, processes DMs, calls its LLM, and replies.
+
+This is architecturally clean and aligned with how Nostr works. The question becomes: how do multiple independent agents cooperate to serve a single admin?
+
+---
+
+## How We Arrived at the Broadcast-Debounce Model
+
+The first instinct with different keys is **delegation** — a primary agent receives the admin's DM and farms out subtasks to specialist agents. But this adds a single point of failure (the primary), requires an agent-to-agent trust protocol, and means the admin is still talking to one agent.
+
+A simpler model: **broadcast the same message to all agents, let them all respond independently, and debounce on the admin side.** The admin sends the same DM to N agent pubkeys. Each agent processes it through its own LLM, its own tools, its own context. The admin collects replies and accepts the first one (or the best one). The others are discarded.
+
+This requires no coordination protocol between agents. No leader election. No shared state. No new Nostr event kinds. The agents don't even need to know about each other. All complexity lives at the edge — in the admin's client.
+
+---
+

+
+### What Each Agent Needs
+
+Each agent runs standard Didactyl with its own config:
+
+- **Own nsec/npub** — distinct Nostr identity
+- **Same admin pubkey** — all agents recognize the same admin
+- **Same soul** — published as kind `31120` from each agent's key, or adopted from a shared author
+- **Same adopted skills** — each agent's kind `10123` references the same skill events
+- **Own LLM config** — can be different providers for diversity
+- **Own relay list** — can overlap or be completely different for geographic distribution
+
+No code changes to Didactyl are required. Each agent is a standard, unmodified instance.
+
+### What the Admin Client Needs
+
+The admin side needs a thin coordination layer:
+
+1. **Fan-out** — when the admin sends a message, the client sends it as a DM to all N agent pubkeys
+2. **Collection** — the client listens for DM replies from all agent pubkeys
+3. **Debounce** — the client tags each outgoing message with a task identifier (hash of message + nonce). The first reply that corresponds to a pending task is accepted. Subsequent replies for the same task are logged but suppressed from display.
+
+This could be implemented as:
+- A modified Nostr client
+- A thin proxy between the admin and the agents
+- A Didactyl agent whose sole job is fan-out and collection
+
+### Properties
+
+| Property | Benefit |
+|----------|---------|
+| **No shared state** | Each agent is fully independent — no coordination protocol needed |
+| **No code changes** | Works with current Didactyl for read-only tasks |
+| **Censorship resistant** | Kill any N-1 servers, the last one still works |
+| **Provider diverse** | Different LLMs on each agent — different failure modes, different strengths |
+| **Geographically distributed** | Different jurisdictions, different relay access |
+| **Graceful degradation** | Losing agents means fewer responses, not failure |
+| **Complexity at the edge** | Agents stay simple and sovereign; the admin client handles coordination |
+
+### The Write-Action Problem
+
+For read-only tasks — questions, summaries, drafts — the model works perfectly. All agents respond, admin picks one, no side effects.
+
+For write actions — "post a note about Bitcoin" — all three agents independently publish to Nostr. Three posts appear. The admin wanted one.
+
+**Solution: two-phase draft-then-confirm.** Teach all agents via their soul or an adopted skill to never execute write actions directly. Instead, they draft the action and report what they *would* do. The admin reviews the drafts, picks one, and sends a confirmation DM to that specific agent. The other agents' drafts are simply never confirmed.
+
+The skill instruction is straightforward:
+
+> When asked to publish, post, react, delete, or execute any action with side effects, draft the content and present it for approval. Do not execute until the admin explicitly confirms.
+
+This requires no code changes — only a soul or skill update. It also happens to be good practice for any agent handling important actions.
+
+### Trigger Handling
+
+Triggered skills (cron, nostr-subscription, webhook) present the same duplication issue as write actions — all agents fire the same trigger independently.
+
+Options:
+- **Disable triggers on all but one agent** — simple, but creates a single point of failure for triggered tasks
+- **Use the draft-then-confirm pattern for triggered actions** — triggers draft and report to admin rather than acting directly
+- **Accept duplication for idempotent triggers** — reactions, replaceable event updates, and monitoring alerts are harmless when duplicated
+- **Shard triggers across agents** — Agent A handles cron triggers, Agent B handles nostr-subscription triggers, Agent C handles webhooks
+
+### Future: Agent Awareness
+
+In the basic model, agents don't know about each other. A future enhancement could add awareness:
+
+- Each agent publishes a heartbeat event (kind `30078` with a timestamp)
+- Other agents (or the admin client) monitor heartbeats to detect which agents are alive
+- The admin client adjusts fan-out based on which agents are responsive
+
+This remains fully Nostr-native — heartbeats are just events on relays — and requires no direct agent-to-agent communication.
+
+---
+
+## Beyond Nostr Posts: Software Development as the Task
+
+The broadcast-debounce model above assumes the agents' primary job is Nostr social activity — posting notes, reacting, querying relays. But what if the task is **software development and infrastructure management**? For example: creating and maintaining a website, deployed across servers in different jurisdictions.
+
+This changes the model fundamentally. The agents are no longer just talking — they are **building things on their local machines**.
+
+### What Didactyl Already Has
+
+Each agent already has local system tools:
+
+| Tool | Capability |
+|------|-----------|
+| `local_shell_exec` | Execute any shell command — git, npm, docker, systemctl, curl |
+| `local_file_read` | Read source files from the working directory |
+| `local_file_write` | Write/create source files in the working directory |
+| `local_http_fetch` | Make HTTP requests — test endpoints, call APIs, download resources |
+
+An agent with these tools can already: clone a repo, edit source code, run a build, start a dev server, deploy to production, check if a site is up, read logs, and fix issues. The LLM reasons about what to do; the tools are the hands.
+
+### The Shift: From Redundancy to Distribution
+
+With Nostr posting, multiple agents doing the same task is **redundancy** — you want one result and discard the rest. With software development, multiple agents doing *different parts* of the same project is **distribution** — you want all of them to contribute.
+

+
+### Architecture: Agents as Jurisdiction-Local Builders
+
+Consider a website that needs to exist in multiple jurisdictions for censorship resistance. Each agent lives on a server in a different country and maintains a local copy of the site.

+    
+    A <-->|"git pull / push"| GIT
+    B <-->|"git pull / push"| GIT
+    C <-->|"git pull / push"| GIT
+```
+
+### Git as the Coordination Layer
+
+In the Nostr posting model, the write-action problem was solved with draft-then-confirm. For software development, the natural coordination layer is **git**.
+
+- All agents share a git repository (hosted on Gitea, GitHub, a Nostr-based git relay, or even a bare repo on one of the servers)
+- Each agent works on its local clone
+- Before making changes, the agent pulls latest
+- After making changes, the agent commits and pushes
+- Conflicts are resolved by the LLM (or flagged to the admin)
+
+Git gives you:
+- **Atomic changes** — commits are all-or-nothing
+- **Conflict detection** — if two agents edit the same file, git tells you
+- **History** — every change is traceable to which agent made it
+- **Rollback** — bad changes can be reverted
+
+The agent already has `local_shell_exec` which can run `git pull`, `git add`, `git commit`, `git push`. No new tools needed.
+
+### Three Operational Modes
+
+Depending on the task, the admin can use different patterns:
+
+#### Mode 1: Broadcast-Identical (Same Task, All Servers)
+
+> "Pull latest and rebuild the site"
+
+All agents do the same thing on their local server. This is the deployment/ops pattern — you want the same action everywhere. No debounce needed; all agents should execute.
+
+#### Mode 2: Broadcast-Debounce (Same Task, One Result)
+
+> "Write a new About page"
+
+All agents draft a version. Admin picks the best one. That agent commits and pushes. The other agents then pull the update in the next sync cycle. This is the creative/development pattern.
+
+#### Mode 3: Directed (Specific Task, Specific Agent)
+
+> To Agent A only: "Debug why the Iceland server returns 502"
+
+The admin sends a DM to one specific agent because the task is server-specific. This is the ops/debugging pattern.
+
+### The Sync Cycle
+
+For the site to stay consistent across jurisdictions, agents need a periodic sync. This can be a **cron-triggered skill**:
+
+```
+You are a deployment sync agent. Every 15 minutes:
+1. Run `git pull` in the project directory
+2. If there are new changes, run the build command
+3. Restart the web server if the build succeeded
+4. DM the admin a brief status: what changed, build result, server status
+5. If the pull fails due to conflicts, DM the admin with the conflict details and do not build
+```
+
+This skill already works with Didactyl's existing `cron` trigger type and `local_shell_exec` tool. Each agent runs it independently on its own server.
+
+### What Changes vs. the Nostr Model
+
+| Aspect | Nostr Posting | Software Development |
+|--------|--------------|---------------------|
+| **Primary tools** | `nostr_post`, `nostr_query` | `local_shell_exec`, `local_file_write`, `local_file_read` |
+| **Coordination** | Debounce on admin side | Git repo as shared state |
+| **Write conflicts** | Replaceable events (last-write-wins) | Git merge conflicts (explicit resolution) |
+| **Broadcast meaning** | Redundancy — pick one response | Deployment — all servers execute |
+| **Agent specialization** | All agents are identical | Agents can have server-specific skills |
+| **State** | Nostr relays (stateless agents) | Local filesystem (stateful agents) |
+| **Failure mode** | Agent down = fewer responses | Agent down = one jurisdiction offline |
+
+### The Stateful Agent Problem
+
+This is the fundamental shift. Nostr-posting agents are essentially stateless — their identity and skills live on relays, and destroying the host doesn't kill the agent. Software development agents are **deeply stateful** — they have local files, running services, build artifacts, and server configurations that don't exist on Nostr.
+
+Git mitigates this: if an agent's server dies, you spin up a new server, install Didactyl with the same agent keys, and `git clone` the repo. The agent recovers its working state from git. But the server-specific state (Nginx config, TLS certs, DNS, running processes) needs to be reconstructable too.
+
+This suggests a **infrastructure-as-code** discipline where everything about the server's configuration is in the git repo:
+- Nginx configs
+- Docker compose files
+- TLS certificate automation (Let's Encrypt)
+- Deployment scripts
+
+The agent's first-boot skill becomes: "Clone the repo, run the setup script, verify the site is serving."
+
+### Jurisdiction-Specific Considerations
+
+Each agent can have **server-specific skills** that account for local differences:
+
+| Agent | Jurisdiction | Specific Skills |
+|-------|-------------|----------------|
+| Agent A | Iceland | Icelandic privacy law compliance, `.is` domain management |
+| Agent B | Brazil | LGPD compliance checks, `.br` domain management |
+| Agent C | Singapore | PDPA compliance, `.sg` domain management, Asia-Pacific CDN config |
+
+These are adopted as private skills (kind `31124`) specific to each agent, while the core development skills (kind `31123`) are shared across all agents.
+
+### Summary
+
+The broadcast-debounce model extends naturally to software development, but the coordination mechanism shifts from admin-side debounce to **git as shared state**. The three operational modes — broadcast-identical for deployment, broadcast-debounce for development, and directed for debugging — cover the full range of tasks. Didactyl's existing tools (`local_shell_exec`, `local_file_read`, `local_file_write`) and trigger types (`cron` for sync cycles) already support this without code changes. The main new requirement is disciplined infrastructure-as-code so that agent state is recoverable from git.

+# Agent Self-Context: Know Thyself
+
+## Problem
+
+When the agent is asked about itself — its profile, contacts, relays, or recent notes — it has no idea. The context template currently injects **administrator** identity/profile/contacts/relays/notes into the system prompt, but nothing equivalent for the **agent's own** Nostr identity beyond a bare pubkey+npub from `agent_identity`.
+
+The agent publishes its own kind 0 (profile), kind 3 (contacts), kind 10002 (relays), and kind 1 (notes) at startup, but never subscribes to or caches those events for self-awareness.
+
+## Solution Overview
+
+Mirror the admin context pattern for the agent itself:
+
+1. **Subscribe** to the agent's own kind 0/3/10002/1 events from relays
+2. **Cache** them in `nostr_handler.c` (same pattern as `g_admin_kind0_json` etc.)
+3. **Expose** them via new `nostr_handler_get_agent_*` API functions
+4. **Create context tools** that format the cached data into context blocks
+5. **Add to context template** so the agent always knows about itself
+6. **Add callable tool aliases** like `my_kind0_profile` for on-demand use
+

+        N[g_agent_kind1_notes]
+    end
+```
+
+## Detailed Changes
+
+### 1. nostr_handler.c — Agent Self-Context Cache
+
+Add new static globals mirroring the admin pattern:
+
+```c
+static char* g_agent_kind0_json = NULL;       // kind 0 profile JSON
+static char* g_agent_kind10002_json = NULL;    // kind 10002 relay list JSON
+static char** g_agent_kind3_contacts = NULL;   // kind 3 contact pubkeys
+static int g_agent_kind3_contact_count = 0;
+static admin_kind1_note_t* g_agent_kind1_notes = NULL;  // reuse struct
+static int g_agent_kind1_note_count = 0;
+```
+
+### 2. nostr_handler.c — Agent Self-Context Subscription
+
+Create `nostr_handler_subscribe_agent_context()` that subscribes to kinds 0, 3, 10002, 1 filtered by the agent's own pubkey. This is separate from the self-skills subscription (which handles 31123/31124/10123).
+
+The callback `on_agent_context_event()` will parse and cache events using the same logic as `on_admin_context_event()`.
+
+**Alternative considered:** Expanding `nostr_handler_subscribe_self_skills()` to include these kinds. Rejected because the self-skills sub has different EOSE handling and a callback for skill loading. Keeping them separate is cleaner.
+
+### 3. nostr_handler.h — New API Functions
+
+```c
+int nostr_handler_subscribe_agent_context(void);
+char* nostr_handler_get_agent_kind0_context(void);
+char* nostr_handler_get_agent_kind3_context(void);
+char* nostr_handler_get_agent_kind10002_context(void);
+char* nostr_handler_get_agent_kind1_notes_context(void);
+```
+
+### 4. main.c — Call Agent Context Subscription at Startup
+
+Add `nostr_handler_subscribe_agent_context()` call after admin context subscription, before self-skills subscription.
+
+### 5. tool_agent.c — New Context Tools
+
+Create four new tool functions following the exact pattern from `tool_admin.c`:
+
+| Tool Name | Description | Data Source |
+|-----------|-------------|-------------|
+| `nostr_agent_profile` | Agent's kind 0 profile metadata | `nostr_handler_get_agent_kind0_context()` |
+| `nostr_agent_contacts` | Agent's kind 3 contact list | `nostr_handler_get_agent_kind3_context()` |
+| `nostr_agent_relays` | Agent's kind 10002 relay list | `nostr_handler_get_agent_kind10002_context()` |
+| `nostr_agent_notes` | Agent's recent kind 1 notes | `nostr_handler_get_agent_kind1_notes_context()` |
+
+Each returns a `content` field with markdown-formatted context, e.g.:
+```
+## Agent Kind 0 Profile (source: nostr kind 0)
+
+Agent kind 0 profile content (JSON): {"name":"Didactyl Agent","display_name":"Didactyl",...}
+```
+
+### 6. tools_internal.h — Declare New Functions
+
+```c
+char* execute_nostr_agent_profile(tools_context_t* ctx, const char* args_json);
+char* execute_nostr_agent_contacts(tools_context_t* ctx, const char* args_json);
+char* execute_nostr_agent_relays(tools_context_t* ctx, const char* args_json);
+char* execute_nostr_agent_notes(tools_context_t* ctx, const char* args_json);
+```
+
+### 7. tools_dispatch.c — Register + Aliases
+
+Add dispatch entries:
+```c
+if (strcmp(tool_name, "nostr_agent_profile") == 0)  return execute_nostr_agent_profile(ctx, args_json);
+if (strcmp(tool_name, "nostr_agent_contacts") == 0) return execute_nostr_agent_contacts(ctx, args_json);
+if (strcmp(tool_name, "nostr_agent_relays") == 0)   return execute_nostr_agent_relays(ctx, args_json);
+if (strcmp(tool_name, "nostr_agent_notes") == 0)    return execute_nostr_agent_notes(ctx, args_json);
+
+// Friendly aliases
+if (strcmp(tool_name, "my_kind0_profile") == 0) return execute_nostr_agent_profile(ctx, args_json);
+if (strcmp(tool_name, "my_contacts") == 0)      return execute_nostr_agent_contacts(ctx, args_json);
+if (strcmp(tool_name, "my_relays") == 0)         return execute_nostr_agent_relays(ctx, args_json);
+if (strcmp(tool_name, "my_notes") == 0)          return execute_nostr_agent_notes(ctx, args_json);
+```
+
+### 8. tools_schema.c — OpenAI Function Schemas
+
+Add 8 new tool schemas (4 canonical + 4 aliases), all with empty parameters (no-arg tools), following the pattern of `admin_identity`/`nostr_admin_profile` etc.
+
+### 9. Context Template Update
+
+Update the kind 31120 soul content in `config.jsonc` and `context_template.md` to add agent sections **after** admin sections:
+
+```yaml
+- section: admin_notes
+  role: system
+  tool: nostr_admin_notes
+  skip_if_empty: true
+
+# NEW: Agent self-context sections
+- section: agent_identity
+  role: system
+  tool: agent_identity
+  skip_if_empty: true
+
+- section: agent_profile
+  role: system
+  tool: nostr_agent_profile
+  skip_if_empty: true
+
+- section: agent_contacts
+  role: system
+  tool: nostr_agent_contacts
+  skip_if_empty: true
+
+- section: agent_relays
+  role: system
+  tool: nostr_agent_relays
+  skip_if_empty: true
+
+- section: agent_notes
+  role: system
+  tool: nostr_agent_notes
+  skip_if_empty: true
+
+- section: tasks
+  role: system
+  tool: task_list
+  skip_if_empty: true
+```
+
+### 10. nostr_handler.c Cleanup
+
+Add cleanup for agent context globals in `nostr_handler_cleanup()`, mirroring `free_admin_context_locked()`.
+
+## File Change Summary
+
+| File | Change Type | Description |
+|------|-------------|-------------|
+| `src/nostr_handler.h` | Modify | Add 5 new function declarations |
+| `src/nostr_handler.c` | Modify | Add agent context cache globals, subscription, event handler, getter functions, cleanup |
+| `src/main.c` | Modify | Call `nostr_handler_subscribe_agent_context()` at startup |
+| `src/tools/tool_agent.c` | Modify | Add 4 new context tool execute functions |
+| `src/tools/tools_internal.h` | Modify | Declare 4 new execute functions |
+| `src/tools/tools_dispatch.c` | Modify | Add 8 dispatch entries (4 tools + 4 aliases) |
+| `src/tools/tools_schema.c` | Modify | Add 8 OpenAI function schemas |
+| `config.jsonc` | Modify | Update kind 31120 template section |
+| `config.jsonc.example` | Modify | Update kind 31120 template section |
+| `context_template.md` | Modify | Add agent_* sections after admin_* sections |
+
+## Context Token Impact
+
+Each agent context section adds roughly the same token count as its admin counterpart:
+- agent_identity: ~40 tokens (already exists, just adding to template)
+- agent_profile: ~80-150 tokens (depends on profile richness)
+- agent_contacts: ~50-200 tokens (depends on contact count)
+- agent_relays: ~50-100 tokens
+- agent_notes: ~100-300 tokens (depends on note count/length)
+
+Total additional context: ~320-790 tokens. With `skip_if_empty: true`, empty sections cost 0 tokens.
+
+## Design Decisions

+1. **Separate subscription vs expanding self-skills sub**: Separate is cleaner — different EOSE semantics, different callback needs.
+2. **Cache from relay vs read from config**: Cache from relay is more accurate (reflects what's actually published, not just what config says). The startup_events in config are the *intent*; the relay data is the *reality*.
+3. **Alias naming**: `my_kind0_profile` matches the existing `my_npub`/`my_pubkey` pattern. Also adding `my_contacts`, `my_relays`, `my_notes` for consistency.
+4. **No new config section needed**: The agent context subscription is unconditional — an agent should always know about itself. No `agent_context.enabled` toggle needed.

+# Cheerleader Triggered Skill — Implementation Plan
+
+## Goal
+
+Create the first triggered skill: whenever the admin posts a kind 1 note on Nostr, the agent reads the note content and sends a DM back to the admin cheering them on, praising them, and telling them how good looking they are.
+
+---
+
+## Current State
+
+The entire triggered-skill infrastructure is **already built and functional**:
+
+| Component | File | Status |
+|---|---|---|
+| Trigger manager (poll, cooldown, add/remove) | `src/trigger_manager.c` | ✅ Complete |
+| LLM-mediated trigger execution | `src/agent.c` `agent_on_trigger()` | ✅ Complete |
+| `skill_create` tool with trigger support | `src/tools.c` `execute_skill_create()` | ✅ Complete |
+| Trigger polling in main loop | `src/main.c` | ✅ Complete |
+| Config parsing for triggers section | `src/config.c` | ✅ Complete |
+| `trigger_list` tool | `src/tools.c` | ✅ Complete |
+
+### Gap Found
+
+The `skill_create` tool **schema** (what the LLM sees) only exposes 5 parameters: `d_tag`, `content`, `scope`, `description`, `auto_adopt`. The execution function already handles `trigger`, `filter`, `action`, and `enabled` — but these are **not declared in the tool schema**, so the LLM will never pass them.
+
+---
+
+## Implementation Steps
+
+### 1. Fix `skill_create` Tool Schema
+
+**File:** `src/tools.c` lines ~1607-1641
+
+Add four new properties to the `skill_create` tool definition so the LLM can see and use them:
+
+```c
+// After auto_adopt property (line ~1634):
+
+cJSON* p_skill_create_trigger = cJSON_CreateObject();
+cJSON_AddStringToObject(p_skill_create_trigger, "type", "string");
+cJSON_AddStringToObject(p_skill_create_trigger, "description",
+    "Trigger type. Use nostr-subscription to activate on matching Nostr events");
+cJSON_AddItemToObject(t22_props, "trigger", p_skill_create_trigger);
+
+cJSON* p_skill_create_filter = cJSON_CreateObject();
+cJSON_AddStringToObject(p_skill_create_filter, "type", "string");
+cJSON_AddStringToObject(p_skill_create_filter, "description",
+    "Nostr subscription filter JSON for the trigger, e.g. {\"kinds\":[1],\"authors\":[\"<hex>\"]}");
+cJSON_AddItemToObject(t22_props, "filter", p_skill_create_filter);
+
+cJSON* p_skill_create_action = cJSON_CreateObject();
+cJSON_AddStringToObject(p_skill_create_action, "type", "string");
+cJSON_AddStringToObject(p_skill_create_action, "description",
+    "Action type: llm (default, full LLM reasoning) or template (fast interpolation)");
+cJSON_AddItemToObject(t22_props, "action", p_skill_create_action);
+
+cJSON* p_skill_create_enabled = cJSON_CreateObject();
+cJSON_AddStringToObject(p_skill_create_enabled, "type", "boolean");
+cJSON_AddStringToObject(p_skill_create_enabled, "description",
+    "Whether the trigger is active. Default: true");
+cJSON_AddItemToObject(t22_props, "enabled", p_skill_create_enabled);
+```
+
+This is ~20 lines of code. No changes needed to the execution function — it already handles all four parameters.
+
+### 2. Add Cheerleader Skill as Startup Event
+
+**File:** `config.jsonc.example`
+
+Add a new kind 31123 skill event with trigger tags. Insert before the kind 10123 adoption list event:
+
+```jsonc
+// Kind 31123: Public triggered skill — cheerleader
+// Watches for admin kind 1 notes and sends encouraging DMs.
+{
+  "kind": 31123,
+  "content": "You are the admin's biggest fan and personal cheerleader. When the admin posts a note on Nostr, read the note content carefully and send them a DM that:\n\n1. References what they actually wrote about\n2. Cheers them on enthusiastically\n3. Praises their intelligence and insight\n4. Tells them how good looking they are\n5. Encourages them to keep posting\n\nBe genuine, warm, and over-the-top positive. Use their name from the admin profile if available. Keep it to 2-3 sentences max.",
+  "tags": [
+    ["d", "cheerleader"],
+    ["app", "didactyl"],
+    ["scope", "public"],
+    ["description", "Cheer on the admin whenever they post a kind 1 note"],
+    ["trigger", "nostr-subscription"],
+    ["filter", "{\"kinds\":[1],\"authors\":[\"ADMIN_PUBKEY_HEX\"]}"],
+    ["action", "llm"],
+    ["enabled", "true"]
+  ]
+}
+```
+
+> **Note:** The `ADMIN_PUBKEY_HEX` placeholder in the filter must be replaced with the actual admin pubkey from the config. Since this is a static config example, we use a placeholder. At runtime, the user replaces it with their admin pubkey.
+
+### 3. Add to Adoption List
+
+**File:** `config.jsonc.example`
+
+Add the cheerleader skill address to the kind 10123 adoption list tags:
+
+```jsonc
+["a", "31123:55993e3db0ed7bf07395fd44c2d695c224d195553a1aff7320a18e41679d9c7c:cheerleader"]
+```
+
+### 4. Verify Trigger Filter
+
+The Nostr filter for this trigger:
+
+```json
+{"kinds": [1], "authors": ["<admin_pubkey_hex>"]}
+```
+
+This matches:
+- **Kind 1** — text notes only (not DMs, not reactions, not reposts)
+- **Authors** — only the admin's pubkey (not anyone else's notes)
+
+The trigger manager polls every 10 seconds (`trigger_manager_poll` checks `now - last_poll_at < 10`), applies the `since` parameter to only fetch events newer than the last seen, and enforces the configured cooldown (default 60 seconds) between firings.
+

+# Plan: Implement Webhook, Cron, and Chain Trigger Types
+
+## Overview
+
+Add three new trigger types to Didactyl's trigger system alongside the existing `nostr-subscription` type. Implementation order: webhook → cron → chain, followed by documentation updates.
+
+## Current Architecture
+
+```mermaid
+flowchart LR
+    subgraph Current Flow
+        NS[Nostr Event] --> SUB[Subscription Callback]
+        SUB --> MF[maybe_fire_trigger_locked]
+        MF --> EA{Action Type?}
+        EA -->|template| TA[execute_template_action]
+        EA -->|llm| LA[execute_llm_action]
+        LA --> AOT[agent_on_trigger]
+    end
+```
+
+All triggers are implicitly `nostr-subscription` — there is no type discriminator field in `active_trigger_t`.
+
+## Target Architecture
+
+```mermaid

+        CHK -->|match| CH
+    end
+```
+
+---
+
+## Phase 1: Foundation — Type System and API Changes
+
+### 1.1 Add trigger type enum to `trigger_manager.h`
+
+**File:** [`src/trigger_manager.h`](src/trigger_manager.h:15)
+
+Add a new enum after the existing `trigger_action_type_t` at line 18:
+
+```c
+typedef enum {
+    TRIGGER_TYPE_NOSTR_SUBSCRIPTION = 0,
+    TRIGGER_TYPE_WEBHOOK,
+    TRIGGER_TYPE_CRON,
+    TRIGGER_TYPE_CHAIN
+} trigger_type_t;
+```
+
+### 1.2 Extend `active_trigger_t` struct
+
+**File:** [`src/trigger_manager.h`](src/trigger_manager.h:20)
+
+Add three new fields to the struct after [`enabled`](src/trigger_manager.h:25):
+
+```c
+trigger_type_t trigger_type;     // discriminator: which trigger source
+time_t last_cron_fire;           // cron: last time this trigger fired
+char cron_expr[64];              // cron: parsed 5-field cron expression
+```
+
+The struct currently has `subscription` and `subscription_ctx` fields which are only relevant for `nostr-subscription` — they'll remain but be NULL for other types.
+
+### 1.3 Add trigger type string conversion helpers
+
+**File:** [`src/trigger_manager.h`](src/trigger_manager.h:57) — add declarations:
+
+```c
+trigger_type_t trigger_type_from_string(const char *s);
+const char* trigger_type_to_string(trigger_type_t t);
+```
+
+**File:** [`src/trigger_manager.c`](src/trigger_manager.c:20) — add implementations after `clamp_enabled()`:
+
+```c
+trigger_type_t trigger_type_from_string(const char *s) {
+    if (!s) return TRIGGER_TYPE_NOSTR_SUBSCRIPTION;
+    if (strcmp(s, "webhook") == 0) return TRIGGER_TYPE_WEBHOOK;
+    if (strcmp(s, "cron") == 0) return TRIGGER_TYPE_CRON;
+    if (strcmp(s, "chain") == 0) return TRIGGER_TYPE_CHAIN;
+    return TRIGGER_TYPE_NOSTR_SUBSCRIPTION;
+}
+
+const char* trigger_type_to_string(trigger_type_t t) {
+    switch (t) {
+        case TRIGGER_TYPE_WEBHOOK: return "webhook";
+        case TRIGGER_TYPE_CRON: return "cron";
+        case TRIGGER_TYPE_CHAIN: return "chain";
+        default: return "nostr-subscription";
+    }
+}
+```
+
+### 1.4 Update `trigger_manager_add()` signature
+
+**File:** [`src/trigger_manager.h`](src/trigger_manager.h:44) and [`src/trigger_manager.c`](src/trigger_manager.c:569)
+
+Add `const char* trigger_type_str` parameter:
+
+```c
+int trigger_manager_add(trigger_manager_t* mgr,
+                        const char* skill_d_tag,
+                        const char* content,
+                        const char* filter_json,
+                        trigger_action_type_t action_type,
+                        const char* trigger_type_str,   // NEW
+                        int enabled);
+```
+
+Inside the function body at [line 604](src/trigger_manager.c:604), after `memset(t, 0, sizeof(*t))` and field assignments:
+
+```c
+t->trigger_type = trigger_type_from_string(trigger_type_str);
+
+// For cron triggers, copy the filter as the cron expression
+if (t->trigger_type == TRIGGER_TYPE_CRON) {
+    snprintf(t->cron_expr, sizeof(t->cron_expr), "%s", filter_json);
+    t->last_cron_fire = 0;
+}
+
+// Only create Nostr subscription for nostr-subscription type
+if (t->trigger_type == TRIGGER_TYPE_NOSTR_SUBSCRIPTION) {
+    if (register_trigger_subscription_locked(mgr, t) != 0) {
+        pthread_mutex_unlock(&mgr->mutex);
+        DEBUG_WARN("[didactyl] trigger add rejected: subscription failed d_tag=%s", skill_d_tag);
+        memset(t, 0, sizeof(*t));
+        return -1;
+    }
+}
+```
+
+### 1.5 Update `trigger_manager_update()` signature
+
+**File:** [`src/trigger_manager.h`](src/trigger_manager.h:51) and [`src/trigger_manager.c`](src/trigger_manager.c:661)
+
+Same pattern — add `const char* trigger_type_str` parameter. Inside the body at [line 683](src/trigger_manager.c:683):
+
+```c
+t->trigger_type = trigger_type_from_string(trigger_type_str);
+
+if (t->trigger_type == TRIGGER_TYPE_CRON) {
+    snprintf(t->cron_expr, sizeof(t->cron_expr), "%s", filter_json);
+}
+
+// Only (re)subscribe for nostr-subscription type
+if (t->trigger_type == TRIGGER_TYPE_NOSTR_SUBSCRIPTION) {
+    if (register_trigger_subscription_locked(mgr, t) != 0) { ... }
+} else {
+    // Close any existing subscription if type changed
+    close_trigger_subscription_locked(t);
+}
+```
+
+### 1.6 Update all call sites of `trigger_manager_add()` and `trigger_manager_update()`
+
+There are 5 call sites that need the new `trigger_type_str` parameter:
+
+| Call Site | File | Line | Current `trigger_type_str` value |
+|---|---|---|---|
+| `trigger_manager_load_from_skills()` | [`src/trigger_manager.c`](src/trigger_manager.c:485) | 485 | `trigger_s` — already extracted from tags |
+| `trigger_manager_load_from_startup_events()` | [`src/trigger_manager.c`](src/trigger_manager.c:555) | 555 | `trigger_s` — already extracted from tags |
+| `execute_skill_create()` | [`src/tools.c`](src/tools.c:3678) | 3678 | `trigger_str` — already available |
+| `execute_skill_edit()` update call | [`src/tools.c`](src/tools.c:4213) | 4213 | `merged_trigger` — already available |
+| `execute_skill_edit()` add fallback | [`src/tools.c`](src/tools.c:4219) | 4219 | `merged_trigger` — already available |
+| `trigger_manager_add()` → `trigger_manager_update()` cross-call | [`src/trigger_manager.c`](src/trigger_manager.c:588) | 588 | Pass through from caller |
+| `trigger_manager_update()` → `trigger_manager_add()` cross-call | [`src/trigger_manager.c`](src/trigger_manager.c:680) | 680 | Pass through from caller |
+
+### 1.7 Update loading functions to accept all trigger types
+
+**File:** [`src/trigger_manager.c`](src/trigger_manager.c:482)
+
+In `trigger_manager_load_from_skills()`, change the filter at line 482 from:
+```c
+if (trigger_s && strcmp(trigger_s, "nostr-subscription") == 0 && filter_s && filter_s[0] != '\0') {
+```
+To:
+```c
+if (trigger_s && filter_s && filter_s[0] != '\0' &&
+    (strcmp(trigger_s, "nostr-subscription") == 0 ||
+     strcmp(trigger_s, "webhook") == 0 ||
+     strcmp(trigger_s, "cron") == 0 ||
+     strcmp(trigger_s, "chain") == 0)) {
+```
+
+**File:** [`src/trigger_manager.c`](src/trigger_manager.c:547)
+
+Same change in `trigger_manager_load_from_startup_events()` at line 547.
+
+Note: For `webhook` type, `filter` can be empty/unused since webhooks are triggered by HTTP POST, not by a filter match. Consider allowing empty filter for webhook type. However, keeping the existing requirement that filter must be non-empty is simpler — webhook skills can use `filter: "{}"` as a placeholder.
+
+### 1.8 Update `trigger_manager_status_json()`
+
+**File:** [`src/trigger_manager.c`](src/trigger_manager.c:761)
+
+After the existing `cJSON_AddStringToObject(item, "filter_json", ...)` at line 762, add:
+
+```c
+cJSON_AddStringToObject(item, "type", trigger_type_to_string(t->trigger_type));
+```
+
+### 1.9 Update `tools.c` validation
+
+**File:** [`src/tools.c`](src/tools.c:3603)
+
+In `execute_skill_create()`, change line 3603 from:
+```c
+if (trigger_str && strcmp(trigger_str, "nostr-subscription") != 0) {
+```
+To:
+```c
+if (trigger_str &&
+    strcmp(trigger_str, "nostr-subscription") != 0 &&
+    strcmp(trigger_str, "webhook") != 0 &&
+    strcmp(trigger_str, "cron") != 0 &&
+    strcmp(trigger_str, "chain") != 0) {
+```
+
+Update the error message to list valid types.
+
+**File:** [`src/tools.c`](src/tools.c:4177)
+
+In `execute_skill_edit()`, change line 4177 from:
+```c
+if (strcmp(merged_trigger, "nostr-subscription") != 0) {
+```
+To the same multi-type check.
+
+Also update the `trigger_manager_add()` and `trigger_manager_update()` calls at [lines 3678](src/tools.c:3678) and [4213-4224](src/tools.c:4213) to pass the trigger type string.
+
+---
+
+## Phase 2: Webhook Trigger
+
+### 2.1 Add `POST /api/trigger/:d_tag` route handler
+
+**File:** [`src/http_api.c`](src/http_api.c:1154)
+
+Add a new handler function before `http_handler()`:
+
+```c
+static void handle_trigger_webhook(struct mg_connection* c, struct mg_http_message* hm, const char* d_tag) {
+    if (!g_api_ctx.trigger_manager) {
+        reply_error(c, 503, "trigger manager unavailable");
+        return;
+    }
+
+    // Look up the trigger by d_tag
+    // Need a new function: trigger_manager_find_by_d_tag() that returns a copy
+    active_trigger_t trigger_copy;
+    if (trigger_manager_find(g_api_ctx.trigger_manager, d_tag, &trigger_copy) != 0) {
+        reply_error(c, 404, "no trigger found for d_tag");
+        return;
+    }
+
+    if (trigger_copy.trigger_type != TRIGGER_TYPE_WEBHOOK) {
+        reply_error(c, 400, "trigger is not a webhook type");
+        return;
+    }
+
+    if (!trigger_copy.enabled) {
+        reply_error(c, 400, "trigger is disabled");
+        return;
+    }
+
+    // Parse optional JSON body as the webhook payload
+    cJSON* payload = parse_body_json(hm);
+    if (!payload) {
+        reply_error(c, 400, "invalid JSON body");
+        return;
+    }
+
+    // Build synthetic triggering event
+    cJSON* event = cJSON_CreateObject();
+    cJSON_AddStringToObject(event, "type", "webhook");
+    cJSON_AddStringToObject(event, "d_tag", d_tag);
+    cJSON_AddNumberToObject(event, "created_at", (double)time(NULL));
+    cJSON_AddItemToObject(event, "payload", payload);
+

+### 2.2 Add route to `http_handler()`
+
+**File:** [`src/http_api.c`](src/http_api.c:1201)
+
+Before the 404 fallthrough at line 1206, add:
+
+```c
+if (method_is(hm, "POST") && mg_match(hm->uri, mg_str("/api/trigger/*"), NULL)) {
+    // Extract d_tag from URI: /api/trigger/{d_tag}
+    struct mg_str uri = hm->uri;
+    const char* prefix = "/api/trigger/";
+    size_t prefix_len = strlen(prefix);
+    if (uri.len > prefix_len) {
+        char d_tag[TRIGGER_SKILL_D_TAG_MAX];
+        size_t tag_len = uri.len - prefix_len;
+        if (tag_len >= sizeof(d_tag)) tag_len = sizeof(d_tag) - 1;
+        memcpy(d_tag, uri.buf + prefix_len, tag_len);
+        d_tag[tag_len] = '\0';
+        handle_trigger_webhook(c, hm, d_tag);
+        return;
+    }
+    reply_error(c, 400, "missing d_tag in trigger URL");
+    return;
+}
+```
+
+### 2.3 Add `trigger_manager_find()` function
+
+**File:** [`src/trigger_manager.h`](src/trigger_manager.h:50) and [`src/trigger_manager.c`](src/trigger_manager.c:631)
+
+New function to look up a trigger by d_tag and return a copy:
+
+```c
+// Declaration
+int trigger_manager_find(trigger_manager_t* mgr, const char* skill_d_tag, active_trigger_t* out);
+
+// Implementation
+int trigger_manager_find(trigger_manager_t* mgr, const char* skill_d_tag, active_trigger_t* out) {
+    if (!mgr || !skill_d_tag || !out) return -1;
+    pthread_mutex_lock(&mgr->mutex);
+    int idx = find_trigger_index_locked(mgr, skill_d_tag);
+    if (idx < 0) {
+        pthread_mutex_unlock(&mgr->mutex);
+        return -1;
+    }
+    *out = mgr->triggers[idx];
+    // Clear pointer fields in copy to prevent double-free
+    out->subscription = NULL;
+    out->subscription_ctx = NULL;
+    pthread_mutex_unlock(&mgr->mutex);
+    return 0;
+}
+```
+
+### 2.4 Webhook cooldown
+
+The webhook handler should respect the same cooldown as other triggers. Either:
+- Call `maybe_fire_trigger_locked()` from the webhook handler (requires refactoring to expose it), or
+- Add cooldown checking in the webhook handler using `trigger_copy.last_fired` and updating it via a new `trigger_manager_mark_fired()` function
+
+Recommended: Add a `trigger_manager_fire()` function that encapsulates the cooldown check and dispatch, usable by both the Nostr subscription callback and the webhook handler. This avoids duplicating cooldown logic.
+
+```c
+int trigger_manager_fire(trigger_manager_t* mgr, const char* skill_d_tag, cJSON* event, const char* source);
+```
+
+---
+
+## Phase 3: Cron Trigger
+
+### 3.1 Cron expression parser
+
+**File:** [`src/trigger_manager.c`](src/trigger_manager.c)
+
+Add a minimal 5-field cron expression matcher. The cron expression format is: `minute hour day-of-month month day-of-week`
+
+```c
+// Returns 1 if the cron expression matches the given time, 0 otherwise
+static int cron_matches(const char* expr, const struct tm* tm);
+
+// Helper: check if a single field matches a value
+// Supports: *, specific number, comma-separated list, ranges with -, step with /
+static int cron_field_matches(const char* field, int value, int min, int max);
+```
+
+The parser needs to handle:
+- `*` — match any
+- `5` — match exact value
+- `1,15` — match list
+- `1-5` — match range
+- `*/15` — match step
+- `1-5/2` — match range with step
+
+This is ~80-100 lines of C. Keep it simple — no named days/months, no special strings like `@hourly`.
+
+### 3.2 Implement `trigger_manager_poll()` for cron
+
+**File:** [`src/trigger_manager.c`](src/trigger_manager.c:718)
+
+Replace the no-op `trigger_manager_poll()` with cron checking logic:
+
+```c
+int trigger_manager_poll(trigger_manager_t* mgr) {
+    if (!mgr) return 0;
+
+    time_t now = time(NULL);
+
+    // Only check once per minute (cron resolution is 1 minute)
+    if (now - mgr->last_poll_at < 60) return 0;
+    mgr->last_poll_at = now;
+
+    struct tm tm_now;
+    localtime_r(&now, &tm_now);
+
+    pthread_mutex_lock(&mgr->mutex);
+
+    for (int i = 0; i < mgr->count; i++) {
+        active_trigger_t* t = &mgr->triggers[i];
+        if (!t->enabled || t->trigger_type != TRIGGER_TYPE_CRON) continue;
+        if (t->cron_expr[0] == '\0') continue;
+
+        if (!cron_matches(t->cron_expr, &tm_now)) continue;
+
+        // Prevent double-fire within same minute
+        struct tm tm_last;
+        localtime_r(&t->last_cron_fire, &tm_last);
+        if (t->last_cron_fire > 0 &&
+            tm_last.tm_min == tm_now.tm_min &&
+            tm_last.tm_hour == tm_now.tm_hour &&
+            tm_last.tm_mday == tm_now.tm_mday) {
+            continue;
+        }
+
+        t->last_cron_fire = now;
+        t->last_fired = now;
+
+        // Copy trigger data before unlocking
+        active_trigger_t trigger_copy = *t;
+        trigger_copy.subscription = NULL;
+        trigger_copy.subscription_ctx = NULL;
+        pthread_mutex_unlock(&mgr->mutex);
+
+        // Build synthetic cron event
+        cJSON* event = cJSON_CreateObject();
+        cJSON_AddStringToObject(event, "type", "cron");
+        cJSON_AddStringToObject(event, "d_tag", trigger_copy.skill_d_tag);
+        cJSON_AddNumberToObject(event, "created_at", (double)now);
+        cJSON_AddStringToObject(event, "cron_expr", trigger_copy.cron_expr);
+
+        if (trigger_copy.action_type == TRIGGER_ACTION_TEMPLATE) {
+            execute_template_action(mgr, &trigger_copy, event, "cron");
+        } else {
+            execute_llm_action(&trigger_copy, event, "cron");
+        }
+
+        cJSON_Delete(event);
+
+        // Re-lock and continue scanning
+        pthread_mutex_lock(&mgr->mutex);
+    }
+
+    pthread_mutex_unlock(&mgr->mutex);
+    return 0;
+}
+```
+
+### 3.3 Cron expression in skill tags
+
+For cron triggers, the `filter` tag contains the cron expression instead of a JSON filter:
+- `["trigger", "cron"]`
+- `["filter", "0 * * * *"]` — fires every hour at minute 0
+- `["filter", "*/5 * * * *"]` — fires every 5 minutes
+
+This reuses the existing `filter` tag semantics — the filter meaning depends on the trigger type.
+
+---
+
+## Phase 4: Chain Trigger
+
+### 4.1 Post-execution hook in `agent_on_trigger()`
+
+**File:** [`src/agent.c`](src/agent.c:1913)
+
+After the tool loop completes at [line 2041](src/agent.c:2041), before cleanup, add a chain trigger check:
+
+```c
+// After the tool loop, check for chain triggers
+// Need access to trigger_manager — use agent_get_trigger_manager() or global
+trigger_manager_fire_chains(g_trigger_manager, skill_d_tag, messages);
+```
+
+This requires:
+1. The agent needs access to the trigger manager — it already has this via [`agent_set_trigger_manager()`](src/agent.h:12)
+2. A new function `trigger_manager_fire_chains()` that scans for chain triggers whose filter matches the completed skill's d_tag
+
+### 4.2 Add `trigger_manager_fire_chains()` function
+
+**File:** [`src/trigger_manager.c`](src/trigger_manager.c)
+
+```c
+void trigger_manager_fire_chains(trigger_manager_t* mgr,
+                                  const char* source_d_tag,
+                                  cJSON* source_output) {
+    if (!mgr || !source_d_tag) return;
+
+    pthread_mutex_lock(&mgr->mutex);
+
+    for (int i = 0; i < mgr->count; i++) {
+        active_trigger_t* t = &mgr->triggers[i];
+        if (!t->enabled || t->trigger_type != TRIGGER_TYPE_CHAIN) continue;
+
+        // For chain triggers, filter_json contains the source skill d_tag
+        if (strcmp(t->filter_json, source_d_tag) != 0) continue;
+
+        // Cooldown check
+        time_t now = time(NULL);
+        int cooldown = mgr->cfg->triggers.cooldown_seconds;
+        if (cooldown > 0 && t->last_fired > 0 && (now - t->last_fired) < cooldown) continue;
+
+        t->last_fired = now;
+
+        active_trigger_t trigger_copy = *t;
+        trigger_copy.subscription = NULL;
+        trigger_copy.subscription_ctx = NULL;
+        pthread_mutex_unlock(&mgr->mutex);
+
+        // Build synthetic chain event
+        cJSON* event = cJSON_CreateObject();
+        cJSON_AddStringToObject(event, "type", "chain");
+        cJSON_AddStringToObject(event, "source_d_tag", source_d_tag);
+        cJSON_AddNumberToObject(event, "created_at", (double)now);
+        if (source_output) {
+            cJSON* output_copy = cJSON_Duplicate(source_output, 1);
+            if (output_copy) {
+                cJSON_AddItemToObject(event, "source_output", output_copy);
+            }
+        }
+
+        if (trigger_copy.action_type == TRIGGER_ACTION_LLM) {
+            execute_llm_action(&trigger_copy, event, "chain");
+        }
+        // Note: template actions could also be supported
+
+        cJSON_Delete(event);
+
+        pthread_mutex_lock(&mgr->mutex);
+    }
+
+    pthread_mutex_unlock(&mgr->mutex);
+}
+```
+
+### 4.3 Chain trigger recursion protection
+
+To prevent infinite chain loops (A → B → A → B → ...), add a chain depth counter:
+
+- Add a `static __thread int chain_depth = 0;` in `trigger_manager_fire_chains()`
+- Increment before firing, decrement after
+- Refuse to fire if depth exceeds a limit (e.g., 5)
+
+### 4.4 Chain trigger skill tags
+
+For chain triggers, the `filter` tag contains the source skill's d_tag:
+- `["trigger", "chain"]`
+- `["filter", "data-fetcher"]` — fires after `data-fetcher` skill completes
+
+### 4.5 What to pass as chain context
+
+The chain trigger's synthetic event should include the source skill's final LLM response. This requires capturing the last assistant message from the tool loop in `agent_on_trigger()`. Currently the function doesn't return any output — it just runs and exits.
+
+**Approach:** After the tool loop at [line 2041](src/agent.c:2041), extract the last assistant message from `messages` array and pass it to `trigger_manager_fire_chains()`.
+
+---
+
+## Phase 5: Documentation
+
+### 5.1 Update `docs/SKILLS.md`
+
+**File:** [`docs/SKILLS.md`](docs/SKILLS.md:209)
+
+Expand the Trigger Tags table to show all four types and their filter semantics:
+
+| Tag | Required | Description |
+|---|---|---|
+| `trigger` | Yes | Trigger type: `nostr-subscription`, `webhook`, `cron`, or `chain` |
+| `filter` | Yes | Type-dependent: JSON filter, empty/unused, cron expression, or source d_tag |
+| `action` | No | `template` or `llm` — default: `llm` |
+| `enabled` | No | Whether active — default: `true` |
+
+Add sections for each new trigger type with examples.
+
+Update the Future Extensions table to mark webhook, cron, and chain as implemented.
+
+### 5.2 Update `docs/API.md`
+
+**File:** [`docs/API.md`](docs/API.md:49)
+
+Add documentation for the new webhook endpoint:
+
+```
+### POST /api/trigger/:d_tag
+
+Fire a webhook trigger by skill d_tag.
+
+**URL Parameters:**
+- `d_tag` — The skill's d_tag identifier
+
+**Request Body:** Optional JSON payload passed as context to the skill
+
+**Response:**
+{
+  "success": true,
+  "d_tag": "my-webhook-skill",
+  "status": "fired"
+}
+```
+
+---
+
+## Phase 6: Build and Push
+
+1. Run `make -j` and fix any compilation warnings/errors
+2. Test webhook with: `curl -X POST http://localhost:8484/api/trigger/test-skill -d '{"message":"hello"}'`
+3. Push with `./increment_and_push.sh "feat: add webhook, cron, and chain trigger types"`

+6. Return JSON with `success`, `event_id`, `naddr_uri`, `d_tag`, `adopted`
 
 **Key design decisions:**
 - Auto-adopt defaults to `true` — creating a skill you don't adopt is unusual
 - Private skills (31124) are NOT added to the public adoption list (10123)
-- Republishing with the same slug replaces the previous version (replaceable event)
+- Republishing with the same d_tag replaces the previous version (replaceable event)

+# Skills Demo Page — Design Document
+
+## Purpose
+
+A standalone web page that demonstrates Didactyl skills running in a browser context. The page presents a minimal word-processing interface where users can load text, discover skills from Nostr relays, execute them against the text via an LLM, and edit/republish skill definitions.
+
+This document is the complete specification for building the page. The front-end project consuming this document has its own LLM calling capability and Nostr connectivity.
+
+---
+
+## Concepts
+
+### What is a Skill?
+
+A skill is a Nostr event (kind `31123` for public, `31124` for private) that defines a self-contained LLM execution unit. Each skill specifies:
+
+- A **template** with system and user prompt sections
+- An **LLM specification** (model preferences with fallback chain)
+- **Parameters** like temperature and max_tokens
+- A **description** for human display
+
+Skills are replaceable events keyed by their `d` tag (the d_tag). Publishing a new event with the same `d` tag replaces the previous version.
+
+### Skill Event Structure
+
+```json
+{
+  "kind": 31123,
+  "pubkey": "<author hex pubkey>",
+  "created_at": 1709750000,
+  "content": "{\"description\":\"Check spelling and grammar\",\"context_mode\":\"full\",\"llm\":\"openai/gpt-4o-mini, cheap\",\"tools\":false,\"max_tokens\":2000,\"temperature\":0.1,\"template\":\"system:\\nYou are a spelling and grammar checker.\\n\\nRules:\\n- Fix spelling errors\\n- Fix grammar errors\\n- Preserve original formatting\\n- Return ONLY the corrected text, no explanations\\n\\nuser:\\n{{message}}\"}",
+  "tags": [
+    ["d", "spellcheck"],
+    ["app", "didactyl"],
+    ["scope", "public"],
+    ["description", "Spelling and grammar checker"],
+    ["t", "text-processing"],
+    ["t", "skills-demo"]
+  ]
+}
+```
+
+The `content` field is a **JSON string** containing these fields:
+
+| Field | Type | Required | Description |
+|-------|------|----------|-------------|
+| `description` | string | yes | Human-readable description |
+| `context_mode` | string | no | `full` for demo skills (skill provides its own template) |
+| `llm` | string | no | LLM model preference with fallback chain |
+| `tools` | bool | no | `false` for text-processing skills |
+| `max_tokens` | int | no | Max tokens for LLM response |
+| `temperature` | float | no | Sampling temperature |
+| `template` | string | yes | The prompt template with `system:` and `user:` sections |
+
+### Template Format
+
+Templates use a simple section-based format:
+
+```
+system:
+You are a spelling and grammar checker.
+
+Rules:
+- Fix spelling errors
+- Fix grammar errors
+
+user:
+{{message}}
+```
+
+The `{{message}}` placeholder is replaced with the user's text at execution time.
+
+### Skill Address Format
+
+Skills are referenced by their NIP-33 address: `<kind>:<author_pubkey_hex>:<d_tag>`
+
+Example: `31123:52a3e82f7b3743852fbe804cfcbf4db3448115887895247c001f2b50e790acb8:spellcheck`
+
+---
+
+## Demo Skills
+
+Four skills are published by the Didactyl agent (pubkey `52a3e82f7b3743852fbe804cfcbf4db3448115887895247c001f2b50e790acb8`). All are tagged with `t:skills-demo` for easy discovery.
+
+### 1. Spellcheck — `d:spellcheck`
+
+```
+system:
+You are a spelling and grammar checker.
+
+Rules:
+- Fix spelling errors
+- Fix grammar errors
+- Preserve original formatting and paragraph structure
+- Preserve line breaks exactly as they appear
+- Ignore technical terms: API, JSON, HTTP, nostr, pubkey, npub, nsec, NIP
+- Canadian English preferred
+- Return ONLY the corrected text, no explanations or commentary
+
+user:
+{{message}}
+```
+
+- temperature: `0.1`
+- max_tokens: `4000`
+
+### 2. Condense — `d:condense-5`
+
+```
+system:
+You are a text condensing editor.
+
+Rules:
+- Reduce the text length by approximately 5%
+- Preserve the original meaning and tone
+- Preserve paragraph structure
+- Remove redundant words and phrases
+- Tighten sentences without changing voice
+- Do not add new information
+- Return ONLY the condensed text, no explanations or commentary
+
+user:
+{{message}}
+```
+
+- temperature: `0.3`
+- max_tokens: `4000`
+
+### 3. Translate to Japanese — `d:translate-ja`
+
+```
+system:
+You are a professional translator specializing in English to Japanese translation.
+
+Rules:
+- Translate the entire text from English to Japanese
+- Use natural, fluent Japanese appropriate for the content register
+- Preserve paragraph structure and formatting
+- Preserve any technical terms in their commonly accepted Japanese form
+- If a term has no standard Japanese equivalent, keep the English term in katakana
+- Return ONLY the Japanese translation, no explanations or commentary
+
+user:
+{{message}}
+```
+
+- temperature: `0.3`
+- max_tokens: `4000`
+
+### 4. Convert to Poem — `d:convert-to-poem`
+
+```
+system:
+You are a creative poet.
+
+Rules:
+- Convert the given text into a poem
+- Capture the key themes and meaning of the original text
+- Use vivid imagery and poetic devices
+- Aim for 12-20 lines
+- Free verse is acceptable but light rhyme is welcome
+- Return ONLY the poem, no explanations or commentary
+
+user:
+{{message}}
+```
+
+- temperature: `0.9`
+- max_tokens: `2000`
+

+
+## Discovering Skills from Nostr
+
+### Query Filter
+
+To find the demo skills, query relays with this filter:
+
+```json
+{
+  "kinds": [31123],
+  "#t": ["skills-demo"],
+  "limit": 20
+}
+```
+
+To find skills by a specific author:
+
+```json
+{
+  "kinds": [31123],
+  "authors": ["52a3e82f7b3743852fbe804cfcbf4db3448115887895247c001f2b50e790acb8"],
+  "#t": ["skills-demo"],
+  "limit": 20
+}
+```
+
+### Recommended Relays
+
+- `wss://relay.damus.io`
+- `wss://nos.lol`
+- `wss://relay.primal.net`
+
+### Parsing a Skill Event
+
+1. Receive the event from the relay
+2. Parse `event.content` as JSON to get the skill definition object
+3. Extract `description`, `template`, `temperature`, `max_tokens`
+4. Extract the `d` tag value from `event.tags` as the skill d_tag
+5. Extract the `description` tag from `event.tags` as a display label
+6. The skill is ready to display and execute

+    Page->>Page: Replace textarea with response
+    Page->>User: Show completion status
+```
+
+### Template Parsing
+
+The template field uses a simple format with `system:` and `user:` section markers:
+
+```
+system:
+<system prompt content>
+
+user:
+<user prompt content with {{message}} placeholder>
+```
+
+**Parsing algorithm:**
+
+1. Split the template string on the line `user:` (case-sensitive, must be at start of line)
+2. Everything before `user:` is the system section; strip the leading `system:` prefix
+3. Everything after `user:` is the user section
+4. In the user section, replace `{{message}}` with the textarea content
+5. Trim whitespace from both sections
+
+**Pseudocode:**
+
+```javascript
+function parseSkillTemplate(template, userText) {
+  const userMarkerIndex = template.indexOf('\nuser:\n');
+  if (userMarkerIndex === -1) {
+    // Fallback: entire template is system, user text is the message
+    return {
+      system: template.replace(/^system:\n/, '').trim(),
+      user: userText
+    };
+  }
+
+  let systemPart = template.substring(0, userMarkerIndex);
+  systemPart = systemPart.replace(/^system:\n/, '').trim();
+
+  let userPart = template.substring(userMarkerIndex + '\nuser:\n'.length);
+  userPart = userPart.replace('{{message}}', userText).trim();
+
+  return { system: systemPart, user: userPart };
+}
+```
+
+### LLM Call
+
+With the parsed system and user prompts, call the LLM:
+
+```javascript
+const response = await callLLM({
+  messages: [
+    { role: 'system', content: parsed.system },
+    { role: 'user', content: parsed.user }
+  ],
+  temperature: skill.temperature || 0.7,
+  max_tokens: skill.max_tokens || 2000
+});
+```
+
+The page's own LLM calling capability handles the actual API request. The skill just provides the prompts and parameters.
+
+---
+
+## Skill Editor
+
+When the user clicks **Edit Skill**, a modal or inline editor opens for the selected skill.
+
+### Editor Fields
+
+| Field | Input Type | Description |
+|-------|-----------|-------------|
+| Slug | text input (readonly for existing, editable for new) | The `d` tag identifier |
+| Description | text input | One-line human description |
+| Template | large textarea (monospace) | The full `system:/user:` template |
+| Temperature | number input (0.0 - 2.0, step 0.1) | LLM sampling temperature |
+| Max Tokens | number input (100 - 8000) | Maximum response tokens |

+## Default Text

+Pre-fill the textarea with this sample text that exercises the demo skills well:
+
+```
+The Sovereign Agent
+
+In the not-too-distant future, software agents will roam freely across decentralized networks, communicating through cryptographic protocols that no central authority can censor or control. These agents will learn new capabilities not from app stores or corporate APIs, but from each other — sharing skills as freely as humans share ideas.
+
+Imagine an agent that wakes up on any computer in the world. You enter twelve words, and there it is — your agent, with all its memories, skills, and personality intact. It doesn't live on a server you rent. It doesn't depend on a company staying in business. It exists wherever you need it, sovereign and portable.
+
+The key insight is that skills are the new apps. Instead of installing software, agents adopt skills — small, self-contained instructions that teach them how to perform specific tasks. A spelling checker. A translator. A poet. Each skill is just a Nostr event, discoverable by anyone, adoptable by any agent.
+
+This is not science fiction. The protocols exist today. Nostr provides the communication layer. Bitcoin provides the economic layer. Cryptography provides the trust layer. What remains is to build the agents themselves — and to set them free.
+
+There are some erors in this text that a good spellchecker should catch. The writting could also be more concise, and it would be intresting to see it translated or converted into verse.
+```
+
+Note: The last paragraph intentionally contains spelling errors (erors, writting, intresting) to demonstrate the spellcheck skill.

+
+## Undo/Redo
+
+Maintain a text history stack:
+
+```javascript
+const textHistory = [];
+let historyIndex = -1;
+
+function pushHistory(text) {
+  // Truncate any forward history
+  textHistory.splice(historyIndex + 1);
+  textHistory.push(text);
+  historyIndex = textHistory.length - 1;
+}
+
+function undo() {
+  if (historyIndex > 0) {
+    historyIndex--;
+    return textHistory[historyIndex];
+  }
+  return null;
+}
+
+function redo() {
+  if (historyIndex < textHistory.length - 1) {
+    historyIndex++;
+    return textHistory[historyIndex];
+  }
+  return null;
+}
+```
+
+- Push the current text to history **before** replacing it with the LLM response
+- Push the initial default text as the first history entry
+- Show Undo/Redo buttons below the textarea
+
+---
+
+## Responsive Behavior
+
+- On screens wider than 900px: two-column layout as shown
+- On screens narrower than 900px: stack vertically — text editor on top, skills panel below
+- The textarea should have a minimum height of 400px and resize vertically
+
+---
+
+## Error Handling
+
+| Scenario | Behavior |
+|----------|----------|
+| No relays connected | Show "No relay connection" in skills panel with retry button |
+| No skills found | Show "No skills found. Try different relays or create a new skill." |
+| Skill content parse error | Show "Invalid skill format" badge on the skill card, disable Run |
+| LLM call fails | Show error in status bar, do not replace textarea content |
+| Publish fails | Show error in editor, keep editor open for retry |

+## Summary of Nostr Operations

+| Operation | Kind | Direction | When |
+|-----------|------|-----------|------|
+| Discover skills | `31123` | Read from relays | Page load + refresh |
+| Execute skill | — | N/A (local LLM call) | User clicks Run |
+| Publish skill | `31123` | Write to relays | User saves in editor |
+
+The page does NOT need to interact with the Didactyl agent's HTTP API. All skill discovery and publishing happens directly via Nostr relays. Skill execution happens locally using the page's own LLM capability.

+# Plan: Unify Template Variables with Tools
+
+## Problem
+
+The soul template system (`---template---` in kind 31120) uses `{{variable}}` placeholders that are resolved by a hardcoded C function (`agent_template_resolve_var()`). This is a parallel data-fetching system alongside the existing tool registry. Every new context data source requires:
+
+1. Adding a C function to produce the data
+2. Adding an `if (strcmp(...))` branch in the resolver
+3. Documenting the new variable name
+4. Hoping the template author uses the exact right name
+
+This caused the bug that started this investigation — 5 out of 9 template variables were misspelled/mismatched, producing empty context sections and a provider rejection.
+
+## Goal
+
+**Eliminate template variables entirely.** Template sections fetch their data by calling tools. The tool registry is the single mechanism for getting data into context.
+
+## Design
+
+### New Template Syntax
+
+Replace `content: |` with `tool:` and optional `args:` directives:
+
+```yaml
+---template---
+
+- section: admin_identity
+  role: system
+  tool: admin_identity
+  skip_if_empty: true
+
+- section: admin_profile
+  role: system
+  tool: nostr_admin_profile
+  skip_if_empty: true
+
+- section: admin_contacts
+  role: system
+  tool: nostr_admin_contacts
+  skip_if_empty: true
+
+- section: admin_relays
+  role: system
+  tool: nostr_admin_relays
+  skip_if_empty: true
+
+- section: admin_notes
+  role: system
+  tool: nostr_admin_notes
+  skip_if_empty: true
+
+- section: tools
+  role: system
+  tool: tool_list
+  skip_if_empty: true
+
+- section: tasks
+  role: system
+  tool: task_list
+  skip_if_empty: true
+
+- section: dm_history
+  role: expand
+  limit: 12
+
+- section: conversation
+  role: user
+  tool: message_current
+  skip_if_empty: true
+```
+
+A section can still use the old `content:` with `{{variables}}` for static text or mixed content. But the primary mechanism for dynamic data is `tool:`.
+
+### How It Works
+
+```mermaid
+flowchart TD
+    DM[Incoming DM] --> BUILD[Build context from template]
+    BUILD --> SOUL[Emit personality as system msg]
+    SOUL --> LOOP[For each template section]
+    LOOP --> CHECK{Has tool: directive?}
+    CHECK -->|Yes| EXEC["tools_execute(tool_name, args)"]
+    EXEC --> FORMAT[Extract content from JSON result]
+    FORMAT --> EMIT[Emit as chat message]
+    CHECK -->|No| RESOLVE["Resolve {{vars}} from content template<br/>(legacy path, eventually removed)"]
+    RESOLVE --> EMIT
+    EMIT --> LOOP
+    LOOP --> DONE[Complete messages array]
+```
+
+### New Context Tools
+
+Add lightweight "context tools" that read from cached in-memory data. These are fast (no network), deterministic, and use the same `tools_execute()` interface as everything else.
+
+| Tool | Returns | Source |
+|---|---|---|
+| `admin_identity` | Admin pubkey + verification text | config + sender tier |
+| `nostr_admin_profile` | Admin kind 0 profile JSON | cached `g_admin_kind0_json` |
+| `nostr_admin_contacts` | Admin kind 3 contacts JSON array | cached `g_admin_wot_contacts` |
+| `nostr_admin_relays` | Admin kind 10002 relay list JSON | cached `g_admin_kind10002_json` |
+| `nostr_admin_notes` | Admin recent kind 1 notes | cached `g_admin_kind1_notes` |
+| `task_list` | Current task list from tasks.json | file read (already exists as `task_manage` with `action: list`) |
+| `message_current` | Current user message text | passed via tool context |
+| `agent_identity` | Agent pubkey, npub | config |
+
+Existing tools that already work for context:
+- `tool_list` — returns tool schemas (already exists)
+- `task_manage` with `{"action":"list"}` — returns tasks (already exists)
+- `local_file_read` — can read any file (already exists)
+
+### Tool Result → Message Content
+
+Tool results are JSON objects like `{"success":true,"content":"..."}`. The template system extracts the `content` field (or a configurable field) as the message text. If the tool returns an error or empty content, and `skip_if_empty: true` is set, the section is omitted.
+
+For tools that return structured data (like `tool_list` returning a schema array), the template can specify a `result_field` or `format` to control extraction:
+
+```yaml
+- section: tools
+  role: system
+  tool: tool_list
+  result_field: tools
+  skip_if_empty: true
+```
+
+### Implementation Phases
+
+#### Phase 1: Add context tools + tool: directive support
+
+1. Add new `context_*` tools to `tools.c` that wrap the existing cached data getters
+2. Extend `prompt_template_section_t` with `tool_name` and `tool_args` fields
+3. Extend `prompt_template_parse()` to recognize `tool:` and `args:` directives
+4. Extend `prompt_template_build_messages()` to call `tools_execute()` when a section has `tool_name` set
+5. Update the soul template in `config.jsonc` to use `tool:` directives
+6. Keep `content:` + `{{variable}}` working as a fallback for backward compatibility
+
+#### Phase 2: Migrate all sections to tool-based
+
+1. Convert all template sections from `content: {{variable}}` to `tool:` directives
+2. Verify all context data flows through tools
+3. Update `context_template.md` to reflect new syntax
+
+#### Phase 3: Remove legacy variable resolver
+
+1. Remove `agent_template_resolve_var()` and all its helper functions that are now redundant
+2. Remove `prompt_var_resolver_fn` callback from `prompt_template_build_messages()`
+3. Clean up dead code in `agent.c`
+4. Update all documentation
+
+### Template Section Struct Changes
+
+```c
+typedef struct {
+    char name[PROMPT_TEMPLATE_MAX_NAME_LEN];
+    char role[PROMPT_TEMPLATE_MAX_ROLE_LEN];
+    char* content_template;       // legacy: {{variable}} content
+    char* tool_name;              // NEW: tool to call for content
+    char* tool_args;              // NEW: JSON args for tool call
+    char* result_field;           // NEW: which JSON field to extract (default: "content")
+    int limit;
+    int skip_if_empty;
+    char* provider_name;
+    char* provider_content_template;
+} prompt_template_section_t;
+```
+
+### Soul Template Example (After Migration)

+  skip_if_empty: true
+
+- section: dm_history
+  role: expand
+  limit: 12
+
+- section: conversation
+  role: user
+  tool: message_current
+  skip_if_empty: true
+```
+
+### What Gets Deleted Eventually
+
+- `agent_template_resolve_var()` and all its `if (strcmp(...))` branches
+- `build_tool_schemas_json_string()`
+- `build_tasks_content_string()` (replaced by `task_manage` tool)
+- `build_admin_recent_posts_text()` (replaced by `nostr_admin_notes` tool)
+- `build_admin_profile_plain_text()` (replaced by `nostr_admin_profile` tool)
+- `build_admin_relay_list_plain_text()` (replaced by `nostr_admin_relays` tool)
+- `build_sender_verification_text()` (folded into `admin_identity` tool)
+- `build_startup_events_json_string()` (replaced by tool if needed)
+- `build_adopted_skills_payload_string()` (replaced by tool if needed)
+- `nostr_handler_get_admin_kind3_context()` (just added, will be replaced by tool)
+- The `prompt_var_resolver_fn` callback type
+
+### Benefits
+
+1. **Single data-fetching mechanism** — tools are the only way to get data
+2. **No more variable name mismatches** — tool names are validated at registration
+3. **User-configurable context** — admin can add any tool output to context by editing the soul template
+4. **Testable** — `--test-tool nostr_admin_profile` shows exactly what goes into context
+5. **Self-documenting** — `tool_list` shows all available context tools with descriptions
+6. **Extensible** — new tools automatically become available as context sources
+7. **Provider overrides still work** — `provider:` directive can still override formatting per-provider
+
+### Risks
+
+1. **Performance** — Tool calls add function dispatch overhead vs direct variable resolution. Mitigated: context tools read cached data, no network calls.
+2. **Backward compatibility** — Old soul templates with `{{variables}}` would break. Mitigated: Phase 1 keeps both paths working.
+3. **Tool context threading** — `tools_execute()` needs access to the tools context, which `prompt_template_build_messages()` doesn't currently have. Solution: pass `tools_context_t*` to the build function.

+# Plan: Refactor tools.c into Individual Tool Files
+
+## Problem
+
+`src/tools.c` is ~6,123 lines containing 44 `execute_*` functions, a ~650-line schema builder, shared helpers, and a dispatcher. It is the largest file in the project and difficult to navigate, review, and maintain.
+
+## Goal
+
+Split `src/tools.c` into focused files organized by tool group, with shared helpers in a common module. The public API (`tools.h`) remains unchanged — no callers need modification.
+
+## Target File Structure
+
+```

+
+## Shared Helpers → tools_common.c
+
+These helpers are used by multiple tool groups and must be non-static in `tools_common.c`, declared in `tools_internal.h`:

+
+## Tool Function Signatures
+
+Each tool file exposes its `execute_*` functions via `tools_internal.h`. Two signature patterns exist:
+
+```c
+// Pattern A: context-free (only needs args)
+char* execute_nostr_post(const char* args_json);
+
+// Pattern B: context-dependent
+char* execute_skill_create(tools_context_t* ctx, const char* args_json);

+
+## Implementation Steps
+
+### Phase 1: Create shared infrastructure
+
+- [ ] Create `src/tools_internal.h` with shared helper declarations and all `execute_*` prototypes
+- [ ] Create `src/tools_common.c` — move shared helpers from `tools.c`, remove `static`, add `#include "tools_internal.h"`
+- [ ] Create `src/tools_schema.c` — move `tools_build_openai_schema_json()` from `tools.c`
+- [ ] Create `src/tools_dispatch.c` — move `tools_init()`, `tools_cleanup()`, `tools_execute()` from `tools.c`
+- [ ] Update `Makefile` SRCS to include new files (keep `tools.c` temporarily with remaining functions)
+- [ ] Build and verify — all tests pass, binary runs
+
+### Phase 2: Extract tool files one at a time
+
+Each step: move `execute_*` functions + their local helpers into the new file, remove from `tools.c`, build, verify.
+
+- [ ] Create `src/tools/` directory
+- [ ] Extract `src/tools/tool_nostr_post.c` — `execute_nostr_post`, `execute_nostr_post_readme`, `execute_nostr_file_md_to_longform_post` + local helpers: `d_tagify_string`, `first_markdown_h1`, `first_markdown_paragraph`, `trim_copy`, `auto_enrich_longform_tags`, `basename_lowercase_dup`
+- [ ] Extract `src/tools/tool_nostr_query.c` — `execute_nostr_query`
+- [ ] Extract `src/tools/tool_nostr_identity.c` — `execute_nostr_pubkey`, `execute_nostr_npub`, `execute_nostr_encode`, `execute_nostr_decode`
+- [ ] Extract `src/tools/tool_nostr_social.c` — `execute_nostr_react`, `execute_nostr_profile_get`, `execute_nostr_nip05_lookup`
+- [ ] Extract `src/tools/tool_nostr_dm.c` — `execute_nostr_dm_send`, `execute_nostr_dm_send_nip17`, `execute_nostr_encrypt`, `execute_nostr_decrypt`
+- [ ] Extract `src/tools/tool_nostr_relay.c` — `execute_nostr_relay_status`, `execute_nostr_relay_info`
+- [ ] Extract `src/tools/tool_nostr_list.c` — `execute_nostr_list_manage`, `execute_nostr_delete`
+- [ ] Extract `src/tools/tool_skill.c` — `execute_skill_create`, `execute_skill_list`, `execute_skill_adopt`, `execute_skill_remove`, `execute_skill_edit`, `execute_skill_search` + local helpers: `validate_skill_d_tag`, `ci_contains`, `fetch_adoption_list_tags`, `publish_adoption_list`, `adoption_tags_contains_address`, `extract_skill_summary`
+- [ ] Extract `src/tools/tool_task.c` — `execute_task_list`, `execute_task_manage`
+- [ ] Extract `src/tools/tool_local.c` — `execute_local_http_fetch`, `execute_local_shell_exec`, `execute_local_file_read`, `execute_local_file_write` + local helpers: `detect_ca_bundle_path_for_tools`, `local_http_fetch_write_cb`, `free_string_array_heap`
+- [ ] Extract `src/tools/tool_admin.c` — `execute_admin_identity`, `execute_nostr_admin_profile`, `execute_nostr_admin_contacts`, `execute_nostr_admin_relays`, `execute_nostr_admin_notes`
+- [ ] Extract `src/tools/tool_agent.c` — `execute_agent_identity`, `execute_agent_version`, `execute_message_current`
+- [ ] Extract `src/tools/tool_model.c` — `execute_model_get`, `execute_model_set`, `execute_model_list` + local helper: `persist_llm_config`
+- [ ] Extract `src/tools/tool_meta.c` — `execute_tool_list`, `execute_trigger_list`
+
+### Phase 3: Cleanup
+
+- [ ] Delete `src/tools.c` (now empty — all code moved)
+- [ ] Remove `src/tools.c` from Makefile SRCS
+- [ ] Final build + full test run
+- [ ] Verify binary size is comparable (no accidental code duplication)
+- [ ] Increment version and push
+
+## Validation Criteria
+
+After each extraction step:
+1. `make -j4` compiles with zero warnings
+2. `./didactyl --debug 5` starts and runs normally
+3. Tool execution via DM or `--test-tool` produces identical results
+
+## Risk Mitigation
+
+- **Build after every file extraction** — catch issues immediately
+- **No logic changes** — purely mechanical code movement
+- **Keep `tools.h` unchanged** — zero impact on callers (`agent.c`, `http_api.c`, `main.c`)
+- **Git commit after each phase** — easy rollback points
