Configuration

Required Settings

• ask_starknet_path: Absolute path to your ask-starknet repository
• At least one LLM API key:
  • anthropic_api_key: For Claude models (recommended)
  • gemini_api_key: For Google Gemini models
  • openai_api_key: For OpenAI models

Optional Settings

• starknet_rpc_url: Starknet RPC endpoint

Usage

1. Open the Agent Panel in Zed (View → Agent Panel)

3. Ask Starknet-related questions:
   • "What's the current block number?"
   • "Check the balance of address 0x..."

Troubleshooting

• "ask_starknet_path not found": Ensure the path is absolute and points to your built ask-starknet repo
• "index.js not found": Run pnpm -w build in the ask-starknet directory

• Process not starting: Run zed --foreground to see detailed logs
