marin: Skill for Claude Code

.agents/skills/manage-hero-run/SKILL.md

manage-hero-run is a skill for Claude Code, Codex from marin-community/marin. It costs 34 tokens per session (3,164 once invoked), scanned A, original, Apache-2.0.

A workflow for launching, resuming, monitoring, handing off, or closing a named production-critical Marin machine-learning run.

In plain words
What is it for?
Use it when the request explicitly concerns a hero or production-critical run. It helps arrange monitoring, classify the run, preserve a run record, and identify when human authorization is needed.
Why use it?
It provides an operating process for long-running or important runs, including monitoring and recording their status and outputs.

About the project

Marin is an open-source research program, software platform, and community for developing foundation models such as large language models. Researchers use it for data preparation, tokenization, pretraining, posttraining, evaluation, and related experiments, including work on audio-text, DNA, and protein models. The catalogue entries are add-ons that support workflows around Marin.

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

manage-hero-run scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Manage Hero Run

Use this skill only when the request names a hero or production-critical run, or another selected workflow explicitly delegates its management here. Within this workflow, about 1e22 model FLOPs (using a 6ND estimate) is the normal threshold for classifying a run as production rather than bounded diagnostic work; it is not an activation trigger by itself.

Operating Model

  • If the user asks to launch a run, arrange babysitting unless they explicitly decline.
  • Use a 15 minute default check cadence for babysitting unless the run's failure mode requires tighter monitoring.
  • Never stop, restart, or bounce an Iris cluster without explicit user permission.
  • If something needs human judgment or authorization, attempt to contact the DRI, usually the user in the chat, through available channels such as GitHub issue comments, Discord, email, or Slack.

Classify the run before loading supporting workflows:

  • A production run is long-lived, has a durable output contract, or is expected to exceed the 1e22 FLOP guideline. It requires the full run record below.
  • A bounded diagnostic has a small fixed step or time limit, lifecycle-managed output, no canonical export, and one monitoring owner. Record its launch contract in the originating conversation or durable session channel. Do not create an issue or logbook solely to submit it.

Do not load run-research, task-logbook, task-snapshot, file-issue, or their writing guides for a bounded diagnostic. Load them only when the run requires the artifact they govern.

Launch

Start from the user's reference command or the nearest existing launcher. Read that launcher's README and --help, then apply only the requested differences. Do not reconstruct the experiment from implementation internals or add a launcher when existing flags express the run.

Resolve the launch blockers first:

  1. Confirm the requested source commit is present with a direct ancestry check.
  2. Inspect the reference job read-only for the fields that the new run must preserve.
  3. Choose unique job, run, output, checkpoint, and rendezvous identities.
  4. Print the dry plan and exact submit command.
  5. Submit once the checks below are resolved. Issue setup, prose polishing, broad repository tests, and prior-work searches do not block a bounded diagnostic.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
