cc-safe-setup

Safety-first configuration for Claude Code. Prevents the accidents that happen when AI writes code autonomously.

What it does

Installs pre-built safety hooks into your Claude Code environment. These hooks run automatically before/after tool calls to block dangerous operations.

Categories:

• File protection: Block rm -rf, prevent overwriting files outside project
• Git safety: Prevent force-push to main, block reset --hard
• Credential guards: Stop .env files from being committed or read by AI
• Token optimization: Warn on large file reads, limit subagent spawning
• Quality gates: Detect lazy rewrites, verify claims before committing

Quick start

npx cc-safe-setup

This runs an interactive wizard that configures hooks based on your risk profile.

Install individual hooks

npx cc-safe-setup --install-example large-read-guard
npx cc-safe-setup --install-example prevent-rm-rf
npx cc-safe-setup --install-example git-force-push-block

Why hooks instead of CLAUDE.md rules

Rules in CLAUDE.md are suggestions — Claude can forget them. Hooks are enforced at the system level. A hook that blocks rm -rf cannot be overridden by the AI.

From 800+ hours of autonomous operation: the hooks that matter most are the ones you don't notice until something goes wrong.
