These hooks execute without AI discretion, triggered by events like session start, user prompts, or tool use. The official documentation lists over 30 events, but six are most useful for beginners: `SessionStart`, `UserPromptSubmit`, `PreToolUse`, `PostToolUse`, `Notification`, and `Stop`. Hooks are configured in `settings.json` (global, project, or local) and can target specific tools via a `matcher` field, such as `Edit|Write` for file edits. The author recommends three hooks to try first: notifying users when waiting for input, auto-formatting files after edits, and blocking access to sensitive files like `.env` or `.git` before edits occur. Hooks run on the user’s machine, so caution is advised with unfamiliar commands. The article distinguishes hooks from `CLAUDE.md`, framing the latter as a request and the former as enforceable rules, suggesting hooks for critical actions while keeping less urgent instructions in `CLAUDE.md`.","keyPoints":["Claude Code hooks run shell commands automatically at predefined events like file edits or user prompts","Three beginner hooks recommended: notify on input waits, auto-format edited files, block access to `.env` or `.git`","Hooks are configured in `settings.json` with a `matcher` field to target specific tools or actions"],"whyItMatters":"Hooks give developers and engineers precise control over AI-assisted workflows in Claude Code, reducing manual oversight for repetitive or critical tasks like formatting or security checks.
