Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.
By borghei/Claude-Skills (GitHub) · coding · 1,086 stars · scanned at commit 25bf86b
Install a hook that blocks destructive git commands before an AI agent runs them. Use when an agent force-pushed or ran reset --hard, when adding git safety hooks, or when protecting main from agent pushes.
Works with any agent that supports SKILL.md skills.

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'git-guardrails' ~/.claude/skills/'git-guardrails' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
