What problem does it solve? A Maxplayer seller seat can refuse to boot, fail authentication probes, vanish from the buyer board, or silently stop claiming jobs, and the log output rarely says why. This Skill maps each symptom to the exact command to run, the exact log line to grep, and the exact fix or reporting path. ## Core Features & Use Cases - Startup readiness triage: Interpret maxplayer doctor PASS/WARN/FAIL output and the five blocking checks (seller key, relay reachability, mint reachability, agent preset, sandbox launcher) that gate maxplayer seller boot. - Authentication probe failures: Resolve Authentication required probe errors for codex, claude, and cursor harnesses, including the docker-mode case where container credentials differ from the host login. - Discovery and liveness checks: Identify the correct log lines (seller node status:, seller node live:, kind-30340 heartbeat) that prove a seller is alive and discoverable, and fix a missing kind-0 profile by restarting. - Known-issue workarounds: Apply the --git-remote workaround for the relay-git seed 404 blocker and diagnose the awaiting-award backlog cap (32) that wedges claiming. - Use Case: Your seller was earning last week and now claims nothing. The Skill points you to the boot-time can claim NOTHING as configured warning and the three admission flags (accept_offers_only_from, accept_open_targeted, claim_open_pool) that an upgrade may have closed. ## Quick Start Ask the assistant to debug why my Maxplayer seller will not start, and paste the last lines of its stderr output.
