Claude Code in Action

https://anthropic.skilljar.com/claude-code-in-action

• Tips

  • #: set memory
  • @: mention files
  • Ctrl-v: paste image

• Context

  • Escape: interrupt and redirect the conversation
  • Double-tap Escape: rewind the conversation
  • /compact: summarize current conversation for things learned and continue a related task
  • /clear: dump current conversation and start an unrelated task

• Intelligence

  • Planning mode for breadth-first tasks
  • Thinking mode for depth-first tasks. Use keywords (sorted from less to more tokens):
    • Think: Basic reasoning
    • Think more: Extended reasoning
    • Think a lot: Comprehensive reasoning
    • Think longer: Extended time reasoning
    • Ultrathink: Maximum reasoning capability

• Custom commands

  • Create a markdown in .claude/commands/<COMMAND>.md.
  • In the command, use $ARGUMENTS to receive user prompt. For example,
    • Create .claude/commands/test.md:

      Your task is to write tests for $ARGUMENTS
      

    • Usage: /test the User model
  • I found if you create commands in ~/.claude/commands/, they become global. For example,
    • Create ~/.claude/commands/backup.md:

      Create a backup for ~/.claude/CLAUDE.md using gist
      

    • Use in any conversation: /backup

• MCP servers

  • Add server

    claude mcp add playwright npx @playwright/mcp@latest
    

  • Pre-configure permissions: open the .claude/settings.local.json file and add the server to the allow array:

    {
      "permissions": {
        "allow": ["mcp__playwright"],
        "deny": []
      }
    }
