Claude Code Gists

Claude Code Gists

A collection of personal hooks for Claude Code. These are my personal Claude Code hooks - use at your own risk!

Hooks

Pre-Tool Use Hooks

• command-safety-guard.py - Validates bash commands and blocks potentially dangerous operations
• security-audit.py - Audits file operations for security concerns
• task-quality-analyzer.py - Analyzes task descriptions for clarity and completeness

Post-Tool Use Hooks

• dependency-checker.py - Checks for outdated dependencies in package.json, Cargo.toml, requirements.txt, pyproject.toml, and Python scripts
  • Supports npm packages with version range parsing
  • Supports Rust crates with cargo integration
  • Supports Python packages in requirements.txt and pyproject.toml
  • Supports PEP 723 inline script metadata in .py files
  • Uses uv if available for faster Python dependency resolution
  • Blocks writes with outdated dependencies

User Prompt Submit Hooks

• user-prompt-hook.py - Advanced prompt engineering for Claude Code (improv: mode only)
  • ONLY processes prompts with improv: prefix - normal prompts bypass hook to avoid lag
  • Uses Claude Sonnet v4 with --append-to-system-prompt for enhancement
  • Adds enhanced prompts as context (doesn't replace original)
  • Includes conversation history for context-aware enhancements
  • Logs all interactions to ~/.claude/hooks-using-claude/prompt_history.json

Notification Hooks

• notification-handler.sh - Handles system notifications for Claude Code events
