Four new on-demand skills using Claude Code's PreToolUse hooks:
- /careful: warns before destructive commands (rm -rf, DROP TABLE, force-push, etc.)
- /freeze: blocks file edits outside a specified directory
- /guard: composes both into one command
- /unfreeze: clears freeze boundary without ending session
Pure bash hook scripts with Python fallback for JSON edge cases.
Safe exceptions for build artifacts (node_modules, dist, .next, etc.).
Hook fire telemetry logs pattern name only (never command content).
