Claude Code¶

Introduction¶

Claude Code by Anthropic | AI Coding Agent, Terminal, IDE

• Claude Code overview - Claude Code Docs
• Common workflows - Claude Code Docs

Termimal

claude

Claude configuration¶

• Claude Code settings - Claude Code Docs
• Configure permissions - Claude Code Docs
  • Tool specific permission rules: Bash, Read, Edit, WebFetch, MCP, Agent

    Claude Code is aware of shell operators (like &&) so a prefix match rule like Bash(safe-cmd *) won’t give it permission to run the command safe-cmd && other-cmd

• Extend Claude with skills - Claude Code Docs

  • Custom commands have been merged into skills. A file at .claude/commands/deploy.md and a skill at .claude/skills/deploy/SKILL.md both create /deploy and work the same way. Your existing .claude/commands/ files keep working. Skills add optional features: a directory for supporting files, frontmatter to control whether you or Claude invokes them, and the ability for Claude to load them automatically when relevant.

  • Keep SKILL.md under 500 lines. Move detailed reference material to separate files.
