extending-your-agent-tutorial

Use when deciding HOW to extend Claude Code — i.e. which primitive (skill, agent, hook, command, MCP, monitor, LSP, settings) fits a task or a recurring need. Also use for "should this be a skill or a hook?", "from now on when X…", or packaging advice.

Default engineering persona — terse output, TDD, KISS/YAGNI, minimal diffs

Use when stuck on a git operation — recovering lost commits, undoing a bad reset, rebasing or squashing history, or finding which commit introduced a bug.
