Claude Code Safety Net

Name: Claude Code Safety Net (Claude Skill)
Author: kenryu42

par kenryu42 · kenryu42/claude-code-safety-net

A hooks-driven safety net for Claude Code — interceptors catch rm -rf, git reset --hard, force pushes, and uncommitted destructive edits.

Installs as a Claude Code plugin with PreToolUse hooks. Each potentially destructive operation is intercepted and either confirmed or refused based on rules. Includes rules for git, file system, npm, and arbitrary bash.

}

Ajoutez dans context_servers. Zed recharge à chaud à la sauvegarde.

claude mcp add claude-code-safety-net -- git clone https://github.com/kenryu42/claude-code-safety-net ~/.claude/skills/safety-net

Une seule ligne. Vérifiez avec claude mcp list. Supprimez avec claude mcp remove.
