README

force-push-guard (Chapter 6 sidebar: Mods)

A minimal Claude Code mod. It registers one tool.call hook, limited to Bash, that refuses any git push with --force or -f before the command runs.

Validated 2026-10-02 on Claude Code 2.1.287 (mods shipped in that release):

$ claude plugin validate ./force-push-guard
  ❯ ./register.js hooks: tool.call{tool=Bash}
  ❯ ./register.js calls: nothing on $
✔ Validation passed

Try it for one session without installing:

claude --plugin-dir ./force-push-guard
