Debug and fix failures in Taskcluster tasks. Use this skill when the user asks to debug a task, fix a failing task, or investigate task errors/failures. This skill uses the Taskcluster CLI to fetch task logs and definitions, analyzes errors, and uses `taskgraph load-task --develop` to reproduce and debug issues locally. Invoke this for any request involving Taskcluster task debugging, task failures, or when given a task ID to investigate.
