- Claude Code hooks are powerful but can be confusing to implement.
- Hooks can be configured globally (~/.claude/settings.json) or per-project (.claude/settings.json).
- Project settings are ideal for team-wide automation like running linters before commits.
- To catch all file modifications, use the regex pattern "Edit|MultiEdit|Write".
- Organize hook scripts in a dedicated directory (e.g., claude-hooks/) for maintainability.
- Example pre-commit hook runs Rubocop and RSpec before git commits.
- Use $CLAUDE_TOOL_INPUT to inspect and react to Claude's tool execution details.
- Debug hooks by capturing output to a file (e.g., foo.json) for inspection.
- Manage hooks interactively using the /hooks command in the Claude CLI.
- Hooks enable consistent, automated development practices across teams.
