Claude Code Safety Kit

Stop Claude Code from deleting your files

Real incidents this prevents:

• 3,467 files (7 GB) deleted without confirmation (#46058)
• Entire user profile deleted via NTFS junctions — 165 GB (#36339)
• Production data deleted via NFS mount (#36640)

Claude Code ships with no protection against destructive commands. This kit fixes that.

A ready-to-use safety kit built from 800+ hours of autonomous Claude Code operation. Drop these hooks into your project and prevent disasters before they happen.

What's Inside (12 files)

5 Safety Hooks:

• destructive-guard.sh — Blocks rm -rf, git reset --hard, and other dangerous commands
• main-branch-guard.sh — Prevents direct pushes to main/master
• secret-scan-guard.sh — Stops .env files and API keys from being committed
• large-read-guard.sh — Warns before reading large files (saves tokens)
• syntax-check-after-edit.sh — Auto-validates Python/JS/JSON/YAML after every edit

Templates & Guides:

• settings.json — Pre-configured hook settings, copy and go
• CLAUDE_MD_TEMPLATE.md — Project rules template
• TIPS_800_HOURS.md — Hard-won tips from 800hrs of autonomous operation
