Save Skill

The user wants to save what was done in this session as a reusable Claude Code skill.

Steps

1. Review the session: Look at what was accomplished — the tools used, files modified, commands run, and the overall workflow.

2. Identify the reusable pattern: What was the core workflow or technique? Strip away project-specific details and extract the generalizable process.

3. Ask the user:

   • "What should this skill be called?" (suggest a name based on what was done)
   • "Should this be a project skill (.claude/skills/) or a personal skill (~/.claude/skills/)?"
   • "Should only you be able to invoke it, or should Claude use it automatically when relevant?"

4. Create the skill: Write the SKILL.md file with:

   • YAML frontmatter: name, description, and disable-model-invocation: true if user-only
   • Clear step-by-step instructions based on what was done
   • Use $ARGUMENTS for any variable parts (file names, branch names, etc.)
   • Keep it under 500 lines — move detailed reference to supporting files if needed

5. Verify: Show the user the created skill and explain how to invoke it with /skill-name.

Example output

If the session involved setting up a new API endpoint:

.claude/skills/new-endpoint/SKILL.md

---
name: new-endpoint
description: Scaffold a new REST API endpoint with tests and documentation
disable-model-invocation: true
---

Create a new API endpoint for $ARGUMENTS:

1. Create the route handler in src/routes/
2. Add request/response validation schemas
3. Write integration tests
4. Update the API documentation
5. Run tests to verify

Important

• Don't include project-specific file paths — use patterns like "src/routes/" not "/Users/alice/myproject/src/routes/"
• Include any commands that should be run (test, lint, build)
• If the workflow has multiple variants, use $ARGUMENTS to parameterize
