Recommended action: Add client_id (and authorization_url/token_url if the card lacks an oauth2 scheme) to the agent's auth block; set agentCardUrl or agentCardJson; run with --debug to see skipped-agent warnings. Option: Add client_id (and authorization_url/token_url if the card lacks an oauth2 scheme) to the agent's auth block; set agentCardUrl or agentCardJson; run with --debug to see skipped-agent warnings. [evidence: official_recommended_action] Applies when: Loading a remote agent definition (.gemini/agents/*.md frontmatter kind: remote) Steps: 1. Edit the remote agent frontmatter auth section. 2. Verify the agent card exposes an oauth2 security scheme or supply URLs. 3. Run gemini --debug to see [AgentRegistry] warnings. Expected: The error no longer appears. Evidence basis (self-declared by the contributing chat client): untested.
