What it does

Fix Issue is an agent skill from MillenniumDawn/Millennium-Dawn. Find an actionable open GitHub issue (or take an issue number or quoted task), implement the fix, commit, update the changelog, and open or update a PR. Use when asked to fix an issue or pick up work from the tracker, e.g. "/fix-issue 1354".

Its SKILL.md is about 990 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 Development, covering Changelog and release notes. It works with GitHub. The repository describes itself as: Millennium Dawn and it's codebase. The licence is CC-BY-SA-4.0.

When your agent uses it

  • Asked to fix an issue
  • Pick up work from the tracker

Example prompts

  • “/fix-issue 1354”
  • “/fix-issue”

Workflow steps

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

  1. Pick the work
  2. Diagnose or plan
  3. Implement
  4. Commit
  5. Changelog
  6. Pull request
  7. Report

What it can do on your machine

Read from SKILL.md and the folder at commit 5821281. 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:

    • git
    • gh

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

  • Network

    No URLs in SKILL.md. Its commands use git and 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 988 tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 547 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~63
When it runs · the whole SKILL.md, loaded when a task matches
~988

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.

description
Find an actionable open GitHub issue (or take an issue number or quoted task), implement the fix, commit, update the changelog, and open or update a PR. Use when asked to fix an issue or pick up work from the tracker, e.g. "/fix-issue 1354".

Implement one actionable issue and open a pull request. Take only work that is small and specified well enough to implement from the issue plus repo context, with no design or balance decision left open.

Arguments: an issue number, a quoted task description, or none to auto-select. Requested arguments: $ARGUMENTS

1. Pick the work

  • A quoted task is the work item. Skip the issue search.
  • An issue number: gh issue view <number> --json title,body,labels,comments.
  • Otherwise list open issues and open PRs (gh issue list --state open --limit 40, gh pr list --state open) and pick an issue no open PR covers.

Eligible work is a bug with a clear reproduction, or a concrete task that names the country, system, or files it touches and has a sibling implementation to mirror.

Skip the issue, and say why, when it is vague, needs a design or balance decision, needs new art, audio, or map assets, spans many systems or countries, or is a large feature. When in doubt, report it back.

With no actionable issue left, work through the "Scan patterns" section of .claude/docs/bug-patterns.md instead.

Claim an issue that passes: gh issue edit <number> --add-assignee @me. Skip this for a quoted task or a scanned bug.

2. Diagnose or plan

Read the issue, then the code it names, and understand the data flow before editing.

  • Bug: trace where the wrong value or branch comes from. Confirm the cause in code. Do not guess.
  • Task: find a sibling implementation and reuse its structure.

Produce an edit list: the exact files, blocks, and new text, with every value, name, loc key, and ordering resolved. Note related out-of-scope problems and leave them alone.

3. Implement

Make the smallest change that resolves the issue. Follow AGENTS.md and the matching .claude/docs/ reference, and add every required loc key. Do not refactor nearby code or fix unrelated problems in the same commit.

A one-line edit is made directly. For a larger edit list, the mechanical typing may go to a head-mod-developer subagent with the edit list verbatim, an instruction to stay within the listed files, and verification greps to report. Check its git diff --stat before committing.

Show full SKILL.md (188 more words)Show less

4. Commit

Always branch from main, never from whatever branch the session started on:

git fetch origin
git checkout -b <slug> origin/main

<slug> is a short kebab-case description, not an issue number. Stage only the files for this work:

git commit -m "<Fix|Add|Implement> <short description> (#<issue>)" -m "<one or two sentences: the cause and fix, or what was added>"

Then git merge origin/main so the branch is current before the changelog and PR.

5. Changelog

Every PR that touches game files gets exactly one BLUF line in Changelog.txt, placed by the /changelog rules and committed separately as Update Changelog.txt:

 - [TAG] <Past-tense verb> <what the player sees> (Issue #N)

Skip it only when the diff has no game files, and say so in the report.

6. Pull request

Push, then check for an open PR on the branch:

git push -u origin <branch>
gh pr list --head <branch> --state open --json number,url,body
  • No open PR: hand off to /open-pr <issue number>. It owns the create path.
  • An open PR exists: update its body in the /open-pr format with gh pr edit <PR#> --body-file <file>. Do not create a second PR. Keep every Closes #N line and any test-plan section already there.

Omit Closes # for a quoted task or a scanned bug.

7. Report

The PR URL, whether it was created or updated, the changelog line or why it was skipped, and a short summary of what was fixed or added.
