What this skill does
Customize your own agent — add capabilities, install packages, add MCP servers, edit code or CLAUDE.md. Use when the user asks you to add a feature, install a tool, or modify how you work. For non-trivial code changes, delegate to a builder agent via create_agent. You can modify your own environment. Different kinds of changes have different workflows.
When it triggers
- Use when the user asks you to add a feature, install a tool, or modify how you work.
