# 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: `slug`, `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.

## File Changes Summary
|
||||
|
||||
| File | Change | Lines |
|
||||
|---|---|---|
|
||||
| `src/tools.c` | Add trigger/filter/action/enabled to skill_create schema | ~20 lines added |
|
||||
| `config.jsonc.example` | Add cheerleader skill startup event | ~20 lines added |
|
||||
| `config.jsonc.example` | Add cheerleader to adoption list | 1 line added |

|
||||
|
||||
## Testing
|
||||
|
||||
1. Build with `make`
|
||||
2. Start the agent
|
||||
3. Verify trigger loads on startup via `trigger_list` tool or HTTP API `/status`
|
||||
4. Post a kind 1 note from the admin account
|
||||
5. Wait up to ~10 seconds for the poll cycle
|
||||
6. Receive a cheerful DM from the agent
|
||||
7. Verify cooldown works — posting again within 60s should not trigger a second DM
