Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

Git Guardrails

Sets up a PreToolUse hook that intercepts and blocks dangerous git commands before Claude executes them.

What You Get

  • PreToolUse hook blocking destructive git operations
  • Project-scoped or global installation
  • Customizable blocked command patterns
  • Verification test command

What Gets Blocked

  • git push (all variants including --force)
  • git reset --hard
  • git clean -f / git clean -fd
  • git branch -D
  • git checkout . / git restore .

When blocked, Claude sees a message telling it that it does not have authority to run these commands.

WRONG: no guardrails, Claude runs destructive commands silently

# Claude decides to "clean up" and runs:
git reset --hard HEAD~3   # 3 commits of work gone
git clean -fd             # untracked files deleted
git push --force          # rewrites shared history

CORRECT: hook blocks before execution

$ echo '{"tool_input":{"command":"git push --force"}}' | block-dangerous-git.sh
BLOCKED: git push is not allowed. Ask the user to run it manually.

Setup Steps

  1. Ask scope -- project (.claude/settings.json) or global (~/.claude/settings.json)?
  2. Copy hook script -- bundled at [scripts/block-dangerous-git.sh](scripts/block-dangerous-git.sh). Copy to .claude/hooks/ (project) or ~/.claude/hooks/ (global). Make executable.
  3. Add to settings -- see [settings-config.md](settings-config.md) for the JSON
  4. Customize -- ask if user wants to add/remove patterns from the blocked list
  5. Verify -- echo '{"tool_input":{"command":"git push origin main"}}' | should exit code 2 with BLOCKED message
