SKILL.md

Skill Editor

Edit existing AI agent skills while keeping Claude, Codex, and Cursor in sync.

Workflow

  1. Always edit Claude first - .claude/skills/<name>/SKILL.md is the canonical source
  2. Replicate with CLI - Copy changes to .codex/skills/ and .cursor/skills/
  3. Never edit Codex/Cursor directly - They are copies of Claude's version

Finding Existing Skills

List all skills:

bash
ls -la .claude/skills/

Read a skill:

bash
cat .claude/skills/<name>/SKILL.md

Editing a Skill

  1. Read the current skill content from .claude/skills/<name>/SKILL.md
  2. Make the requested changes
  3. Replicate to other agents:
    bash
    cp .claude/skills/<name>/SKILL.md .codex/skills/<name>/
cp .claude/skills/<name>/SKILL.md .cursor/skills/<name>/

Verification

Always verify sync after editing:

bash
diff .claude/skills/<name>/SKILL.md .codex/skills/<name>/SKILL.md
diff .claude/skills/<name>/SKILL.md .cursor/skills/<name>/SKILL.md

No output means files are identical.
