Define a method

python3 smalltalk.py define-method Counter "increment
    count := (count ifNil: [0]) + 1.
    ^ count"
Delete a method

βš™οΈ Configuration

1. Set up Squeak with MCP server β€” see SQUEAK-SETUP.md 2. Configure Clawdbot β€” see CLAWDBOT-SETUP.md

πŸ“‹ Tips & Best Practices

  • Requires xvfb for headless operation on Linux servers
  • Uses Squeak 6.0 MCP server (GUI stays responsive if display available)
  • saveImage intentionally excluded for safety
  • MCPServer version 7+ required (v7 adds class-side method support)
  • Playground mode: ephemeral, .changes β†’ /dev/null
  • Dev mode: persistent, .changes kept, requires --dev --image PATH
