The user wants to save what was done in this session as a reusable Claude Code skill.
Review the session: Look at what was accomplished — the tools used, files modified, commands run, and the overall workflow.
Identify the reusable pattern: What was the core workflow or technique? Strip away project-specific details and extract the generalizable process.
Ask the user:
Create the skill: Write the SKILL.md file with:
disable-model-invocation: true if user-only$ARGUMENTS for any variable parts (file names, branch names, etc.)Verify: Show the user the created skill and explain how to invoke it with /skill-name.
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
