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.

claude mcp add claude-code-safety-net -- git clone https://github.com/kenryu42/claude-code-safety-net ~/.claude/skills/safety-netワンライナー。claude mcp list で確認、claude mcp remove で削除。
使うタイミング： You've been bitten by an agent overwriting uncommitted changes.
git reset --hard; expect block.✓ コピーしました結果： Destructive ops require explicit override.
Pairs naturally with any agent doing repo edits
