  • Safety and automation: block dangerous commands, auto-format code, and run tests as part of the development workflow.
  • Guided configuration: simple YAML-based settings.json to compose layered hooks and matchers for different tools.

Quick Start

Create a basic .claude/settings.json with a SessionStart hook and start Claude Code to see the welcome message.
