Security Claude Code Hooks
8 hooks in the Security category. Each installs in one command and drops straight into your .claude directory.
File Protection
Protect critical files from accidental modification. Prevents editing of important system files, configuration files, and production code.
Security Scanner
Scan code for security vulnerabilities and secrets after modifications. Uses multiple security tools to detect potential issues.
Secret Scanner
Automatically detects hardcoded secrets before git commits. Scans for API keys from 30+ providers (Anthropic: sk-ant-..., OpenAI: sk-..., AWS: AKIA..., Stripe: sk_live_..., Google: AIza..., GitHub: ghp_..., Vercel, Supabase, Hugging Face: hf_..., Replicate: r8_..., Groq: gsk_..., Databricks: dapi..., GitLab, DigitalOcean, npm, PyPI, and more), tokens, passwords, private keys, and database credentials. Blocks commits containing secrets and suggests using environment variables instead.
Dangerous Command Blocker
Advanced protection against dangerous shell commands with multi-level security. Blocks catastrophic operations (rm -rf /, dd, mkfs), protects critical paths (.claude/, .git/, node_modules/), and warns about suspicious patterns. Features: catastrophic command blocking, critical path protection, smart pattern detection, and detailed safety messages.
Env File Protection
Prevent writing to .env files using the if condition for lightweight filtering. Blocks any Write tool call targeting .env* files, protecting secrets from accidental overwrites. Uses the if field to avoid spawning a process unless the file pattern matches.
Force Push Blocker
Block git force push commands using the if condition for efficient filtering. Prevents accidental force pushes that can overwrite remote history. Covers --force, --force-with-lease, and the -f shorthand.
Shell Wrapper Guard
Detects destructive commands hidden inside shell wrappers (sh -c, bash -c, python3 -c, node -e, perl -e, ruby -e). Complements dangerous-command-blocker by catching bypass vectors like 'sh -c "rm -rf /"' that evade direct command checks. Covers 8 bypass patterns: interpreter one-liners, nested wrappers, pipe-to-shell, here-strings, and env-based wrappers.
Ai Bash Guard
AI-powered bash command security guard. Before any Bash command runs, a lightweight Claude subagent evaluates it for destructive or irreversible patterns — recursive deletes, force pushes to protected branches, database drops, and credential exposure — and blocks execution with a clear explanation if flagged. Uses PreToolUse with type:agent, which is the only hook pattern that can block tool execution via AI reasoning.
