Configure interceptors and response conversion for a remote A2A agent

Goal

Connect to a remote A2A agent while keeping request boundaries and response handling reviewable.

Steps

1. Verify the remote agent card, advertised capabilities, and expected service domain. [a2a]
2. Set request_interceptors, card_request_interceptors, and response converters in RemoteA2aAgent(config=A2aRemoteAgentConfig(...)). [a2a]
3. Limit data sent to the remote agent and validate response events before returning them to the caller. [a2a]
4. Test success, timeout, and malformed-response cases against a test endpoint without leaking auth headers. [a2a]

How to verify

Outbound requests use only the intended domain and least privilege; response events match the local contract and credentials stay out of logs.

Troubleshooting

If a reply cannot be mapped, check the event converter and protocol version; for auth failures inspect the credential provider, not hard-coded tokens.
