Hand side tasks to Claude Code subagents

Run your own commands automatically with Claude Code hooks
Hooks are shell commands that Claude Code runs at fixed moments, such as before a command or after an edit. Log what Claude runs, block what it must never run, check every file it edits, and get told when it is waiting for you.

Permission modes, allow and deny rules, and where to put them, so Claude Code stops asking about the safe things and never touches the ones that matter.
