What it does

Triage Canary is an agent skill from marin-community/marin. Triage a failed canary ferry run only when invoked by CI with the required CANARY context.

Its SKILL.md is about 750 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Deployment. It works with Kubernetes. The repository describes itself as: Open-source framework for the research and development of foundation models. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Deployment

Example prompts

  • “/triage-canary”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Gather diagnostics
  2. Identify root cause
  3. File a GitHub issue
  4. Publish the result

What it can do on your machine

Read from SKILL.md and the folder at commit c468793. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • kubectl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use kubectl, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Triage Canary loads about 751 tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 389 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~26
When it runs · the whole SKILL.md, loaded when a task matches
~751

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Skill: Triage Canary

Triage a failed canary ferry run. Diagnose root cause and file a GitHub issue. The workflow sends the immediate Slack failure notice. Diagnosis and reporting only — no code changes, no PRs.

CI invocation context

The Loom launch includes these non-secret values in its goal. Use those values directly instead of inspecting the process environment.

VariableDescription
CANARY_LANEgpu (CoreWeave) or tpu (GCP)
CANARY_JOB_IDIris job ID
CANARY_RUN_IDW&B run ID
IRIS_CONFIGPath to Iris cluster config
IRIS_NAMESPACEKubernetes namespace (CW only)
WANDB_ENTITYW&B entity
WANDB_PROJECTW&B project
GHA_RUN_URLFull URL to the GitHub Actions run

Steps

1. Gather diagnostics

The Actions runner may have exited. Start with the diagnostics artifact linked from GHA_RUN_URL and durable Iris and Finelog logs. Use live cluster commands only when the relevant cluster is still running.

  • Iris job state via iris --config=$IRIS_CONFIG job list when accessible.
  • GPU lane: you have kubectl at ~/.kube/coreweave-iris, namespace $IRIS_NAMESPACE (defaults to iris-ci — the canary shares this namespace with PR CI). Get pod status, controller logs, task pod logs, warning events, pod describe. Filter by iris.job_id=<CANARY_JOB_ID with '/' replaced by '.'> so you only see this canary's pods, not co-tenant CI pods. Example: kubectl -n iris-ci get pods -l iris.job_id=runner.iris-run-job-abc123.
  • TPU lane: use iris process logs and iris job list.
  • Re-run scripts/ci/validate_canary_metrics.py if you need the validation output.

2. Identify root cause

Classify into one of: infra/scheduling, training crash, metric regression, controller bug, data/storage.

Use hypothesis-driven diagnosis: state hypothesis, gather evidence, narrow. Attempt to reproduce the issue locally and minimally. Triple check that you're narrowing down on the same issue as the one that actually broke the canary.

3. File a GitHub issue

Follow the file-issue skill. Use the bug-report template.

  • Title: [canary-{lane}] {short failure description}
  • Labels: bug, agent-generated, canary
  • Body must include a "Canary run context" section with: lane, job ID, GHA run URL, W&B run URL, date.
  • Support your claims using supporting data (e.g. runtime logs)
  • Keep the issue concise and maximally readable for humans.
  • Use GFM to make the details (e.g. log traces, code to reproduce issue) optional and declutter the issue.
  • Use --body-file with a temp file (see file-issue skill for the pattern).
4. Publish the result

Append a typed result in the Loom channel with the issue URL, diagnosis, and GHA_RUN_URL. If root cause is unclear, state that and the best available signal.
