 ### Pipeline Analysis
-1. Use `smith pipelines list <repo> <pipeline_id> --status failed` to focus on failed jobs.
-2. Once you know the pipeline log ID, use `smith pipelines grep <repo> <pipeline_id> <log_id> --reverse` to analyze the logs.
-3. For GitLab artifact-backed failures, use `smith <gitlab-remote-name> pipelines artifacts list <group/project> <pipeline_id> <job_id>` and then `... artifacts grep ... "<regex>"`.
