gh-contribute — Clean PRs to Upstream Repos

Turn local changes into a clean, professional pull request against an upstream repo you don't own. Handles the full fork → branch → commit → push → PR pipeline, and splits work into multiple PRs when the changes span unrelated concerns.

When to Use

  • User wants to contribute to an open-source project they don't have write access to
  • User already has local edits and needs them shipped as a PR upstream
  • User asks to "fork this repo and send a PR"
  • User has mixed changes (e.g. docs + feature + refactor) and wants them split properly

Non-Goals

  • Does not write code changes — assumes the user (or a prior step) already has the desired modifications in the working tree or in their head
  • Does not review the project's own PRs (see gh-tidy)
  • Does not mirror to GitLab/Gitea — GitHub only

Workflow (MANDATORY)

Execute steps in order. Do not skip confirmations.

Step 1: Identify the target repo

Determine the upstream owner/repo:

  1. If the user pasted a URL or owner/repo string → use it
  2. Otherwise run git remote -v in the current directory and pick the origin (if origin is already the user's fork, find the upstream via gh repo view --json parent)

Record three facts:

  • UPSTREAM — e.g. ZenMux/zenmux-doc
  • DEFAULT_BRANCH — from gh repo view $UPSTREAM --json defaultBranchRef -q .defaultBranchRef.name
  • USER_LOGIN — from gh api user -q .login

Step 2: Read the contribution rules

Fetch CONTRIBUTING.md and CODE_OF_CONDUCT.md from upstream (if present) and skim for: commit message format, DCO/CLA requirements, branch naming, PR template. Carry these constraints into subsequent steps.

gh api repos/$UPSTREAM/contents/CONTRIBUTING.md -q .content 2>/dev/null | base64 -d

If the repo has .github/PULL_REQUEST_TEMPLATE.md, use it as the PR body skeleton.

Step 3: Survey the changes

Gather the change set that needs to become PR(s):

git status --porcelain
git diff --stat $DEFAULT_BRANCH...HEAD        # committed
git diff --stat                                # unstaged
git diff --stat --cached                       # staged

Classify files into logical groups. Typical axes:

  • By concern: docs / feature / bugfix / refactor / test / chore
  • By subsystem: unrelated top-level directories usually = separate PRs
  • By dependency: if PR B needs PR A merged first, split and note the dependency

Step 4: Propose a PR plan and confirm

Use AskUserQuestion to present the plan. Options must include at least:

  • Single PR — all changes together. Recommended when changes are cohesive.
  • Split into N PRs — show the proposed titles and file groupings.
  • Abort — something is off, let the user redirect.

Show the plan like:

PR #1 (docs): Update CLAUDE.md to reflect current scripts
  - CLAUDE.md
PR #2 (feat): Add gh-contribute skill bootstrap
  - scripts/new.ts
  - .prompts/contribute.xml

Do not proceed until the user picks an option.

Step 5: Fork (idempotent)

gh repo view $USER_LOGIN/$REPO_NAME >/dev/null 2>&1 \
  || gh repo fork $UPSTREAM --clone=false --remote=false

Ensure a fork remote exists in the local clone:

git remote get-url fork 2>/dev/null \
  || git remote add fork git@github.com:$USER_LOGIN/$REPO_NAME.git

If origin already points at the user's fork, skip the fork remote and use origin.

Step 6: Create branches and commits per PR

For each PR in the plan:

  1. Start from a clean, up-to-date base:
    git fetch origin $DEFAULT_BRANCH
    git checkout -b $BRANCH_NAME origin/$DEFAULT_BRANCH
    
  2. Apply only the files belonging to this PR (use git checkout <sha> -- <paths> or git stash + selective git checkout from a working branch).
  3. Commit with a conventional message. If upstream uses Conventional Commits, match: <type>(<scope>): <subject>. Otherwise mirror the style of the last 10 commits on $DEFAULT_BRANCH.
  4. Sign off if CONTRIBUTING.md requires DCO: git commit -s ....

Branch naming (when upstream doesn't dictate): <type>/<short-slug>, e.g. docs/update-claude-md, feat/add-contribute-skill.

Step 7: Push to fork

git push -u fork $BRANCH_NAME

If origin is already the fork, use origin instead.

Step 8: Open the PR

gh pr create \
  --repo $UPSTREAM \
  --base $DEFAULT_BRANCH \
  --head $USER_LOGIN:$BRANCH_NAME \
  --title "$TITLE" \
  --body "$BODY"

PR body template (adapt to PR template if present):

## Summary

<1-3 bullets explaining what and why>

## Changes

- <bullet per logical change>

## Test plan

- [ ] <how to verify>

## Related

<!-- Link follow-up PRs if split, e.g. "Depends on #123" or "Part 2 of 3" -->

When opening multiple PRs, cross-link them in each body:

## Related
- PR 1/3: #<url>
- PR 2/3: (this PR)
- PR 3/3: #<url>

Step 9: Report back

Output a compact summary:

Opened 2 PRs against ZenMux/zenmux-doc:
  #201 docs: update CLAUDE.md            → https://github.com/.../pull/201
  #202 feat: add gh-contribute skill      → https://github.com/.../pull/202

Splitting Heuristics

Prefer one PR when:

  • All changes serve a single user-visible outcome
  • Total diff < ~300 lines across ≤ 5 files
  • The changes would be awkward to review in isolation

Prefer multiple PRs when:

  • Docs-only changes sit alongside code changes (docs PR lands fast)
  • Refactor + feature — land the refactor first, feature on top
  • Unrelated subsystems touched (e.g. scripts/ + docs_source/)
  • One change is trivially correct and another needs discussion

When in doubt, ask the user.

What NOT to Do

  • Never force-push to a branch that already has a PR with review comments unless the user explicitly asks
  • Never edit upstream's default branch directly — always branch first
  • Never push to upstream — always to the user's fork
  • Never bypass hooks (--no-verify) or skip signing (--no-gpg-sign) unless CONTRIBUTING.md says to or the user explicitly says so
  • Never batch unrelated concerns into one PR just to "ship faster"
  • Never fabricate a PR body — if you can't describe the change, ask the user

Dependencies

# gh CLI (https://cli.github.com/)
brew install gh      # macOS
gh auth login        # one-time

No Python dependencies. This skill is pure gh + git orchestration.

Runtime context (shared)

Before running, read this Skill package's skill.yaml, provided by the host skill-runtime/v1 context. Field resolution order is: current request, project context, personal Preferences, brand Profile, general defaults.

  • Use only fields declared in the Manifest; Profile stores public brand facts, Preferences stores personal work preferences.
  • required: true When a field is missing, ask the user one focused question according to the Manifest's question configuration; save the answer only after the user explicitly agrees.
  • Errors provide a copyable context_id, field path, and source; diagnostic content avoids secrets, full private paths, and raw configuration.

General feedback loop

When the user provides revision feedback during a Skill-driven task, before continuing the current artifact you must perform:

  1. First determine whether the feedback is task-specific(this time only) or reusable(reusable across tasks).
  2. task-specific Modify only the current task, do not change the Skill.
  3. reusable First determine the scope: domain rules update the corresponding canonical Skill first; rules applicable to all Skills update the shared specification first.
  4. After completing rule updates, versioning, lint, and distribution verification, then apply the changes to the current task.
  5. reusable The modification invalidates previous "confirm", "continue", and "send it"; after completing the current artifact modification and read-back, you must stop and wait for the user's next instruction, without automatically proceeding to publish, commit, or other external writes.
