researcher: already available via researcher_agent.server on 9013

This folder contains lightweight A2A agent stubs and an orchestrator example.

Agents (A2A endpoints):

• Planner: localhost:8011 (planner_server.py)
• Executor: localhost:8012 (executor_server.py)
• Researcher: localhost:9013 (existing researcher_agent server)
• Validator: localhost:8014 (validator_server.py)

Orchestrator example:

• orchestrator_a2a.py calls the above endpoints sequentially and saves a JSON result to /tmp.

Run agents (each in its own shell) with:

python planner_server.py
python executor_server.py
python validator_server.py
# researcher: already available via researcher_agent.server on 9013

Then run:

python orchestrator_a2a.py "Your query here"

This setup is intentionally minimal for testing and integration. Replace stubs with real agent implementations (FastA2A/LangGraph/Smolagent/PydanticAI) as needed.
