Claude hook builder

Inspects your repo's existing Claude Code configuration and prints a suggested
hook block you can paste into .claude/settings.json yourself. Read-only: it
never writes the file for you.

Usage

Point it at a repo and it reads the current config and skill inventory:

• reads .claude/settings.json to see which hooks already exist
• greps .claude/skills/**/SKILL.md for tool grants worth gating

It prints the suggested PreToolUse / PostToolUse block to stdout. You review
and paste it in by hand.
