What problem does it solve? When a Webex Calling API call fails, a configuration does not apply, or a wxcli command returns an error, this Skill walks through a structured diagnostic workflow instead of guessing at causes, preventing wasted hours chasing the wrong subsystem. ## Core Features & Use Cases - Auth-first diagnosis: Verifies token validity and OAuth scopes before anything else, since auth and scope issues cause the majority of failures. - Symptom-to-fix mapping: Matches HTTP error codes (401, 403, 404, 409, 429, 400) and SDK behaviors to likely causes and concrete fixes. - Verified root-cause reporting: Enforces a verification gate so conclusions are drawn only from observed command output, never from hypotheses. - Use Case: A wxcli call-queue show command returns a 400 error. The Skill checks the token with wxcli whoami, re-runs the command with --debug, identifies an id-kind mismatch, and confirms the fix by reading the resource back. ## Quick Start Ask the agent to debug why your failing wxcli command or Webex Calling API call is returning an error, providing the symptom or error message.
