debug-task

Diagnose and fix moon tasks that are broken, misconfigured, or behaving unexpectedly. Use this skill when a moon task is failing, not running, skipped, hanging, producing stale or wrong output, cached when it shouldn't be, re-running every time when it should be cached, or when outputs are empty or missing after a cache hit. Also covers pipeline hangs and freezes, tasks that only work in CI but not locally (or vice versa), tasks skipped by --affected, and task inheritance not applying to a project. Activate on any mention of "moon run" or "moon task" combined with a problem — errors, stale cache, missing outputs, wrong results, "nothing to do", or unexpected behavior. Also use for task options like persistent, runInCI, allowFailure, affectedFiles, mutex, timeout, or cacheLifetime, and for task checks (requirement, condition, fingerprint) that make a task fail, skip, or re-run, and project-level taskOptions defaults. This skill is for diagnosing existing tasks, not for creating new tasks, setting up workspaces, configuring toolchains, or learning moon concepts.
