Skills

Reusable instruction sets the agent can pull in on demand — the agentskills.io format.

What a skill is

A folder containing a SKILL.md file with YAML frontmatter (name + description) and markdown instructions. Optional subdirectories hold scripts/, references/, and assets/. Discovery follows progressive disclosure:

1. Catalog (startup) — name + description only.
2. Instructions (activation) — the full SKILL.md body.
3. Resources (on demand) — scripts, references, and assets loaded individually. The agent can open a skill's companion files with view_skill.

Where skills come from

AI Labs scans, in order:

Scope	Locations
Workspace	.cptr/skills, .agents/skills, .claude/skills, .codex/skills
Global (user)	~/.cptr/skills, ~/.agents/skills

The cross-agent convention paths mean skills you already keep for Claude Code or Codex are picked up automatically. Managed skills that AI Labs creates live in .cptr/skills.

Using skills

• Type $ in the chat input to mention a skill and attach its instructions to the message.
• Create a skill from chat — turn a working approach into a SKILL.md with the manage_skill tool.
• Skills are kept tidy automatically by a background review (see below).

Administration

Admins manage the global skill set and shared-skill discovery in Admin → Skills, and can choose the model used for background skill review (or let it follow the current chat model).
