## About

# Skill Creator

Skills are directories with a `SKILL.md` frontmatter, discovered from
named roots. The built-in skills are embedded in the binary and
read-only.

## Choose the scope

- **repo** — `/.agents/skills//`: inside the workspace,
  create/edit directly with write_file / apply_patch / exec.
- **user** — `~/.agents/skills//`: outside the workspace; writing
  it requires the session to be in YOLO mode (the user switches with
  `/permissions` and confirms). Ask the user to switch if the session is
  not already in YOLO mode.

## Structure

Create `//SKILL.md` with frontmatter:

```markdown
---
name: 
description: one or two sentences on when to use this skill
---

```

Add supporting files as needed:
- `references/*.md` — details loaded on demand
- `scripts/*` — executable helpers; set the executable bit, e.g. via
  exec_command `chmod +x scripts/tool.py`
- `assets/*` — non-markdown resources

## Rules

- name: kebab-case, unique across skill roots, no spaces.
- description: say when the user would want this skill so ranking finds it.
- Keep the body actionable; prefer references for background material.
- Never write into the built-in skill area (it is embedded and read-only).

## After creating

- The registry is scanned at process start: a newly created skill is
  discoverable via skill_search and the per-turn skills section after the
  next restart (skill_install is the only tool that reloads immediately,
  and it installs from git).
- Verify by reading back SKILL.md and checking the frontmatter
  (name + description).
