PostToolUse	After a tool finishes execution	Can block result with feedback, or append context

Configuration Locations (per-project discovery)

In any project workspace directory, hooks are automatically discovered from:

1. .claude/settings.local.json
2. .claude/settings.json
3. .claude/hooks.json
4. hooks.json

Example .claude/settings.json
