PicoBot

Skills (initial implementation)

Agent profile injection

PicoBot maintains a persistent agent profile file at ~/.picobot/agent/AGENT.md.

Behavior:
- The directory ~/.picobot/agent is created automatically when needed.
- If AGENT.md does not exist yet, PicoBot creates it with a default profile.
- When the active conversation is empty or has just been reset, AGENT.md is loaded as the first system message in the active history.
- After every configured number of user turns, PicoBot injects the latest AGENT.md content again before the next user message is appended.

Config:
- Set gateway.agent_prompt_reinject_every in ~/.picobot/config.json.
- Default value is 100.
- Set it to 0 to disable periodic reinjection.

This profile is persisted in session history, while the skills index system prompt is still injected dynamically by AgentLoop.

PicoBot now supports filesystem skills.

Skill discovery locations:
- Project skills: .picobot/skills/*/SKILL.md
- User skills: ~/.picobot/skills/*/SKILL.md

Minimal required SKILL.md format:

---
description: Summarize code architecture for Rust projects
---
Optional detailed instructions go here.

Notes:
- The only required frontmatter field is description.
- If name is missing, the folder name is used as the skill name.
- Invalid skill files are skipped with warning logs.

How it is injected:
- AgentLoop adds a system message containing the available skills list (name + description).
- The model can call tool skill_activate with {"name":"<skill-name>"}.
- PicoBot returns the skill body as tool output so the model can follow detailed instructions.

Skill management tool

PicoBot exposes a built-in tool named skill_manage for runtime skill administration.
PicoBot also exposes a read-only tool named skill_list for listing discovered skills without mutation.

Supported actions:
- list: List discovered skills
- get: Read one skill by name
- create: Create a skill under project or user scope
- update: Update description and/or body for an existing skill
- delete: Delete a skill directory
- reload: Re-scan skill directories and refresh the in-memory catalog

Defaults:
- scope defaults to project
- reload defaults to true for create, update, and delete

Example payloads:

skill_list takes no parameters.

{"action":"list"}
{"action":"create","scope":"project","name":"demo-skill","description":"Use when summarizing a Rust crate","body":"Step 1..."}
{"action":"update","scope":"project","name":"demo-skill","description":"Use when reviewing a Rust crate"}
{"action":"delete","scope":"project","name":"demo-skill"}
{"action":"reload"}

Config (optional)

Add skills in config.json:

{
	"skills": {
		"enabled": true,
		"sources": ["project", "user"],
		"max_index_chars": 4000,
		"max_listed_skills": 32
	}
}
