What problem does it solve?

Interact with Mozilla Taskcluster CI to manage tasks and task groups from a single, discoverable interface, replacing ad-hoc CLI usage with a unified workflow.

Core Features & Use Cases

  • Check status and stream logs for individual tasks or entire task groups.
  • Retrieve full artifact lists with URLs and metadata, and fetch full task definitions.
  • Trigger in-tree actions (confirm-failures, backfill, retrigger-multiple) and a generic action interface by name.
  • Cancel task groups (including force) and perform worker-pool operations via the Taskcluster CLI.
  • Convenience: automatically extract task IDs from Taskcluster URLs and provide structured outputs and error handling.

Quick Start

Install the skill and provide a Taskcluster task ID or Firefox CI URL to start querying status, streaming logs, listing artifacts, fetching the full task definition, or triggering in-tree actions.
