-

+4. If the server sends an `ask_for_delegation` tool call with a `chainId` and `scope`:
+   - Fetches CoinFello's delegate address
+   - Rebuilds the smart account using the chain ID from the tool call
+   - Parses the server-provided scope (supports ERC-20, native token, ERC-721, and function call scopes)

 ## Edge Cases
 
 - **No smart account**: Run `create_account` before `send_prompt`. The CLI checks for a saved private key and address in config.
+- **Not signed in**: Run `sign_in` before `send_prompt` if the server requires authentication.
 - **Invalid chain name**: The CLI throws an error listing valid viem chain names.
 - **Missing parent delegation with --use-redelegation**: The CLI exits with an error. Run `set_delegation` first.
+- **Read-only response**: If the server returns a text response with no transaction, the CLI prints it and exits without creating a delegation.
