Skill Creator
Create AI agent skills that work across Claude Code, Codex, and Cursor.
Workflow
- Claude is canonical - Always create/edit in
.claude/skills/<name>/first - Replicate with CLI - Copy to
.codex/skills/and.cursor/skills/usingcp -r - Format differences - Use
sedonly if agent-specific tweaks are needed (rare)

name: Lowercase with hyphens, must match directory namedescription: Explains what the skill does and when to use it. Include keywords users would say to help the agent auto-select this skill.
Optional Fields (Claude-specific, ignored by other agents)
allowed-tools: Tools the agent can use without asking permissionmodel: Override the model for this skillcontext: fork: Run in isolated subagent context
Creating a New Skill
- Ask the user what the skill should do
- Choose a descriptive name (lowercase, hyphens)
- Create the Claude skill:
mkdir -p .claude/skills/<name> - Write
.claude/skills/<name>/SKILL.mdwith proper frontmatter - Replicate to other agents:
cp -r .claude/skills/<name> .codex/skills/ cp -r .claude/skills/<name> .cursor/skills/
Modifying an Existing Skill
- Edit
.claude/skills/<name>/SKILL.md(canonical source) - Replicate changes:
cp .claude/skills/<name>/SKILL.md .codex/skills/<name>/ cp .claude/skills/<name>/SKILL.md .cursor/skills/<name>/
Best Practices
- Keep skills focused on a single capability
- Write clear descriptions with keywords for auto-discovery
- Use
references/for lengthy documentation to keep SKILL.md concise - Test the skill by asking the agent to perform the task
