use-iris

use-iris is a skill for Claude Code, Codex from marin-community/marin. It costs 79 tokens per session (669 once invoked), scanned A, original, Apache-2.0.

A skill for operating Iris, a system that runs and schedules jobs and tasks across computing clusters. It covers job checks, debugging, monitoring, recovery, controller deployments, and temporary GPU or TPU reservations.

In plain words
What is it for?
Use it to inspect jobs and tasks, diagnose scheduling or federation problems, monitor running work, roll out or recover controllers, reserve development accelerators, and handle stuck CoreWeave pods.
Why use it?
It gives an agent a documented way to investigate failed, stuck, pending, or federated work without relying on remembered cluster details.

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.

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

use-iris 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 6d 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 — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Use Iris

Read only the material needed for the request:

Resolve cluster facts from lib/iris/config/<cluster>.yaml; do not copy live coordinates from memory.

Common reads

uv run iris --cluster=<cluster> job describe <job>
uv run iris --cluster=<cluster> task describe <task>
uv run iris --cluster=<cluster> task events <task>
uv run iris --cluster=<cluster> rpc controller list-backends

For a pending federated root, inspect all three parent-side views:

uv run iris --cluster=<parent> job list --prefix <root-job>
uv run iris --cluster=<parent> rpc controller list-peers
uv run iris --cluster=<parent> query \
  "SELECT job_id, peer_id, handoff_state FROM federated_jobs WHERE job_id='<root-job>'"

Only root jobs federate; their whole tree stays on the peer. Parent job describe is the liveness source, while forwarded logs may lag. CoreWeave tasks normally read regional S3 and GCP tasks read GCS.

Temporary outputs

Write bounded diagnostics to $IRIS_OUTPUT_DIR. Iris preserves that directory as one outputs.tar.zst archive per attempt without changing the command outcome when capture fails. Find the archive URI and its uploaded, empty, failed, or unavailable state with:

uv run iris --cluster=<cluster> attempt describe <task>:<attempt>

Use direct object-storage writes for large or durable outputs. See lib/iris/docs/task-outputs.md for retention, limits, and data-access boundaries.

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

use-iris is a skill published in the GitHub repository marin-community/marin (3,403 stars, last pushed today), licensed Apache-2.0. It adds 79 tokens to every session and 669 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
