agent-platform-a2a

This skill should be used when debugging a deployment on Gemini Enterprise Agent Platform: 401 or 403 between agents, "permission denied" on an Agent Runtime agent, "CREDENTIALS_MISSING", "Identity Pool does not exist", an IAM grant that changes nothing, an agent answering confidently with invented data, a deploy failing on an undocumented permission, a 404 for a model that exists, or a "global" vs regional location mix-up. Covers identifying the real caller, why 401 and 403 need opposite responses, Agent Identity principal forms, which region belongs where, and the conditions under which a broken deployment reports success. Use agent-platform-architecture instead for choosing a design.
