At a glance

Fix a GitHub issue on OpenPipe/ART and open a PR. An agent skill from OpenPipe/ART.

  • Works in 5 steps: Read the Issue → Explore, Plan, Implement → Commit and Push → …
  • The user asks to fix
  • SKILL.md covers Workflow, Reference, Dependency Management Tips and Deploying a GPU Cluster, plus 1 more section
  • Calls gh, uv and git; needs GITHUB_TOKEN

What it does

Fix Art Issues is an agent skill from OpenPipe/ART. Fix a GitHub issue on OpenPipe/ART and open a PR. Use when the user asks to fix, solve, or work on an ART issue, or references a GitHub issue URL containing "OpenPipe/ART". Triggers: "fix ART issue", "solve this issue" with an OpenPipe/ART URL, "work on ART N".

Its SKILL.md is about 840 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 AI & LLM Engineering, covering Fine-tuning, Pull requests and Reinforcement learning. It works with GitHub, Qwen and Git. The repository describes itself as: Agent Reinforcement Trainer: train multi-step agents for real-world tasks using GRPO. Give your agents on-the-job training. Reinforcement learning for Qwen3.6, GPT-OSS, Llama… The licence is Apache-2.0.

When your agent uses it

  • The user asks to fix
  • Work on an ART issue
  • References a GitHub issue URL containing OpenPipe/ART

Example prompts

  • “OpenPipe/ART”
  • “fix ART issue”
  • “solve this issue”
  • “/fix-art-issues”

Requirements

  • Python 3
  • A credential in GITHUB_TOKEN

Workflow steps

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

  1. Read the Issue
  2. Explore, Plan, Implement
  3. Commit and Push
  4. Open a Draft PR
  5. Testing

What it can do on your machine

Read from SKILL.md and the folder at commit 12162f2. 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:

    • gh
    • uv
    • git
    • uvx
    • ssh
    • python

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

  • Network

    No URLs in SKILL.md. Its commands use gh, uv, git, uvx and ssh, 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 these keys or tokens, usually read from environment variables:

    • GITHUB_TOKEN

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

Context cost

Fix Art Issues loads about 840 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 401 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~69
When it runs · the whole SKILL.md, loaded when a task matches
~840

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:18
    with the correct branch checked out and `.env` in place (handled by the system-level `fix-art-workspace` skill).

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.

description
Fix a GitHub issue on OpenPipe/ART and open a PR. Use when the user asks to fix, solve, or work on an ART issue, or references a GitHub issue URL containing "OpenPipe/ART". Triggers: "fix ART issue", "solve this issue" with an OpenPipe/ART URL, "work on ART #N".

Fix ART Issue

Fix a GitHub issue on OpenPipe/ART and open a PR.

  • Repo: OpenPipe/ART
  • Base branch: main

Assumes the workspace is already set up with the correct branch checked out and .env in place (handled by the system-level fix-art-workspace skill).

Workflow

1. Read the Issue
gh issue view <number> --repo OpenPipe/ART --json title,body,labels,assignees,comments
2. Explore, Plan, Implement
  • Use the Explore agent to understand relevant code before making changes.
  • Plan clearly, implement with minimal focused changes. No over-engineering.
3. Commit and Push
  • Commit with a message that includes Closes #<issue-number>.
  • Push the feature branch. If HTTPS push fails due to SAML SSO, set SSH remote: git remote set-url origin git@github.com:OpenPipe/ART.git
4. Open a Draft PR
  • gh pr create --base main --draft.
  • PR body: ## Summary, Closes #<number>, ## Changes, ## Test plan.
5. Testing
  • No test artifacts in the final PR: debug prints, test scripts, and temporary changes must NOT be committed.
  • Update the PR's test plan section with detailed results.
  • When testing passes, mark the PR as ready: gh pr ready.

Reference

Read CONTRIBUTING.md at the repo root for guidance on code quality checks (prek), CI cache refresh, and the release process.

Dependency Management Tips

  • Pin versions strictly (==) for critical deps like transformers, trl, unsloth, unsloth-zoo, vllm to avoid surprise breakage from new releases.
  • Don't loosen pins without reason: if a dep was ==X.Y.Z, keep it pinned unless there's a specific reason to change. Don't use >= just because it seems more flexible.
  • uv run fails on macOS for backend deps (apex/torch need CUDA). This is expected — use uvx ruff for linting locally, test on GPU cluster.

Deploying a GPU Cluster

Name the SkyPilot cluster after the branch name without the fix/ prefix, replacing / with - (SkyPilot doesn't allow slashes). For example, if the branch is fix/short-description:

uv run sky launch -c short-description skypilot-config.yaml -y

To connect: ssh short-description

To tear down when done: uv run sky down short-description

GPU Cluster Testing Tips

  • Kill stale GPU processes before re-running tests: nvidia-smi --query-compute-apps=pid --format=csv,noheader | xargs -r kill -9. Previous failed runs leave processes holding GPU memory.
  • Set gpu_memory_utilization in test scripts (e.g. 0.7) — the default 0.9 is too high when Unsloth's training model is also loaded on the same GPU.
  • Redirect test output to a log file: nohup python test.py > /tmp/output.log 2>&1 & then tail -f /tmp/output.log. SSH background tasks lose output when connection drops.
  • Git on cluster: SSH keys may not be configured. Use HTTPS with token: git remote set-url origin https://${GITHUB_TOKEN}@github.com/OpenPipe/ART.git
  • Tear down clusters when done: sky down <cluster-name> -y
