Functions exposed to the LLM to take actions

Name	Description
a2a_list_agentsA	List configured A2A agents with their skills and reachability. Set refresh=true to re-fetch agent cards that were previously cached.
a2a_send_messageA	Send a message to an A2A agent and return its reply. Set provider to "litellm-auto" or "github" when the target agent supports provider selection. The selected provider is carried in the message for the local Copilot A2A agent; other agents may ignore it. Pass task_id to continue an existing task, for example to answer an agent that returned state="input_required". If the agent is still working when timeout_s elapses, this returns done=false with a task_id to poll rather than blocking.
a2a_get_taskA	Get the current state and output of a previously started A2A task.
a2a_cancel_taskB	Cancel a running A2A task and return its final state.
a2a_add_agentA	Register a new A2A agent by its base URL. The agent card is fetched first, so an unreachable URL is rejected instead of being saved. With persist=true the agent is written to the shared registry file and stays available in future sessions.
