What it does

Fix Issue is an agent skill from marin-community/marin. Implement and land a fix for an explicitly identified marin-community/marin GitHub issue.

Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with GitHub. The repository describes itself as: Open-source framework for the research and development of foundation models. The licence is Apache-2.0.

Example prompts

  • “/fix-issue”

What it can do on your machine

Read from SKILL.md and the folder at commit be1f5f1. 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

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

  • Network

    No URLs in SKILL.md. Its commands use gh, 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

Fix Issue loads about 593 tokens when it runs. Until then it costs about 25 tokens; SKILL.md has 338 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~25
When it runs · the whole SKILL.md, loaded when a task matches
~593

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.

Fix a GitHub issue

Read AGENTS.md and the issue guidance in writing-style. Keep issue comments terse: omit filler and repetition, use annotated links, and keep each prose section to three or four sentences. Complete the workflow in order. If blocked, comment on the issue with the last completed state and the blocker.

Research

Use gh to fetch the issue. Read the codebase for all relevant source files. Post one concise comment with Research and Proposed Fix sections.

Before writing code, run a duplicate-work preflight:

  • Check open PRs for the same issue or subsystem (gh pr list --state open --search "<issue-id or keyword>").
  • Check open issues for the same root cause (gh issue list --state open --search "<keyword>").
  • If overlapping work exists, do not open a parallel implementation PR. Add a short issue comment summarizing what you found, and either hand off to the existing PR or scope your change to non-overlapping follow-up work.

In Research, state the cause in two or three sentences and link at most five relevant code locations with short annotations. In Proposed Fix, name the smallest fix and include the failing call chain or a snippet only when needed.

Implementation

Implement on agent/{YYYYMMDD}-fix-{issue-id}.

Testing

Follow write-tests. Prefer a regression test that fails before the fix, extend an existing file, run the narrow test and affected safe suite, then run ./infra/pre-commit.py --all-files --fix. Do not override the configured marker expression.

Uploading

When all tests pass, upload your branch and open a PR following .agents/skills/commit/SKILL.md exactly — use the plain-text format it specifies (no markdown headers, bullet lists, or ## Summary sections; violations are rejected). Attach a comment to the Github issue summarizing the fix.

Monitor the PR

After opening the PR, follow step 9 of .agents/skills/commit/SKILL.md exactly. Its wait_for.py loop owns CI, review feedback, and lifecycle events. Do not start a separate gh pr view or gh pr checks polling loop. Investigate failures, push fixes, and re-arm the wait as that skill specifies.

Post a final issue comment with the landed PR or the last terminal state.
