File contents

Write skills the way $analyze, $plan, $implement, $code-review, and $verify are written.

Target

One job. Imperative. Every line changes behavior.
Body under ~40 lines unless the job is genuinely multi-branch.
Description 50–300 chars: capability first, then Use when + trigger words.
No README, changelog, or theory. No restating model defaults.
References only for platform or schema detail the body cannot hold. Name the file and when to open it.
User-only workflows: disable-model-invocation: true.

Write

Confirm 2–3 trigger prompts with the user.
Pick the platform. Default from the path: .claude → Claude, .agents → Codex, .cursor → Cursor. Ask if unclear.
Write frontmatter, then the body: inspect → act → return → stop.
Run bun ~/.agents/skills/skill-manager/scripts/inspect-description.ts on the skill root.

Personal skills live in ~/.agents/skills/<name>/. Platform layout and frontmatter: claude-code.md, codex.md, cursor.md. Description rules: description-recommandation.md.

Audit

For each line: would removing it change behavior? Delete no-ops, duplicates, and stale rules. State the positive target; keep prohibitions only as hard guardrails.

Online research: $find-docs for current technical docs; $exa-search for broader web research.

After creating or renaming a personal skill icon, run bun ~/.agents/scripts/sync-codex-profile-icons.ts --install. Compat: ~/.claude/skills and ~/.codex/skills symlink to ~/.agents/skills. Do not symlink ~/.cursor/skills.
