Testing Feedback
Thanks for this module! I tested it with the Google ADK hello_world_agent and found an issue.
Setup ✅
- A2A agent running at
http://localhost:9999 - Created
llm.a2a.agentrecord, test connection successful - Assigned agent to thread (GPT-4o)
Issue ❌
Agent delegation doesn't work - LLM acknowledges it will use the agent ("I'll ask the agent...") but never makes the actual tool call. No HTTP request reaches the A2A agent server.
Logs:
INFO: Added A2A capability prompt: 1 agents
INFO: Added 1 A2A delegation tools to thread 1
INFO: Storing 1 A2A tools for provider 1
INFO: POST https://api.openai.com/v1/chat/completions "HTTP/1.1 200 OK"
# No tool call, no request to A2A agent ❌
Questions
- Have you tested end-to-end delegation successfully?
- Which LLM model did you test with?
Suggestion
Add a README with:
- Quick start guide (how to set up an A2A agent)
- Example agent configuration
- Expected behavior
Test env: Odoo 18.0, llm_openai, gpt-4o, Google ADK v1.21.0

@hungpq-ai looking forward to the fixed mergeable code |
- Added llm_openai as a dependency to ensure proper method resolution order. - Introduced a comprehensive README.md detailing features, installation, quick start, and troubleshooting for the LLM A2A integration.
