multi agent

Map the caller, task grant, data audience and execution boundary at each handoff. Explain how a valid internal message can still request an unauthorized action.

Separate false-information spread, borrowed authority and runaway work. Put shared limits and stop checks at the propagation paths, then recover without repeating completed effects.

Map effective authority, test component and handoff boundaries in authorized isolation, and report captured effects with coverage limits. Keep adaptive discovery separate from estimates of production risk.

Define the partner identity, permitted operations, disclosure rules and commitment states. Verify claims against authorized evidence and reconcile disputed or uncertain effects.

Map influence through memory, retrieval, tool metadata, outputs and shared artifacts. Separate persistence from actual impact, govern publication, and recover with explicit coverage of derivatives and ongoing work.

A2A standardises how agents find and talk to each other. It does not decide who to trust, what to share or what to believe, and those three decisions are the answer.
