# 开源贡献助手 · Open Source Contributor

![Version](https://img.shields.io/badge/version-0.2.0-CC785C)

Contribute a clean, professional PR to someone else's GitHub repo — fork, branch,
commit, push, open PR. Auto-splits unrelated changes into separate PRs.

Part of [skills](https://example.com/skills/skills) — by [example.com](https://example.com)

## Install

```bash
npx skills add gh-contribute -g -y
```

Requires: [`gh` CLI](https://cli.github.com/) (authenticated via `gh auth login`) and `git`.
No Python dependencies.

## Usage

Invoke from Claude Code in a repo you want to contribute to:

```
/lov-gh-contribute
```

Or just describe the intent:

> 给 ZenMux/zenmux-doc 提个 PR，把 CLAUDE.md 的 script 列表改掉

The skill will:

1. Detect the upstream `owner/repo` and default branch
2. Read `CONTRIBUTING.md` / PR templates for house rules
3. Survey your changes and propose a PR plan (single or split)
4. Ask you to confirm the plan
5. Fork, branch, commit, push, and open PR(s)
6. Cross-link related PRs when splitting

## When to split into multiple PRs

The skill prefers a single PR when changes are cohesive and under ~300 lines.
It suggests splitting when it sees:

- Docs + code changes mixed (ship docs fast, code reviews slower)
- Refactor + feature (refactor lands first, feature on top)
- Unrelated subsystems touched
- One change is trivially correct, another needs discussion

You always confirm the plan before anything is pushed.

## What it won't do

- Write the code changes for you — assumes the working tree already has edits
- Push to upstream — always pushes to your fork
- Force-push over existing review comments
- Bypass hooks / CI / signing unless you explicitly ask

# 开源贡献助手 · Open Source Contributor

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.

```bash
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):

```bash
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)

```bash
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:

```bash
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:
   ```bash
   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

```bash
git push -u fork $BRANCH_NAME
```

If origin is already the fork, use `origin` instead.

### Step 8: Open the PR

```bash
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):

```markdown
## 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:

```markdown
## 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

```bash
# 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)

运行前读取本 Skill 包的 `skill.yaml`，由宿主提供 `skill-runtime/v1` 上下文。字段解析顺序为：当前请求、项目上下文、个人 Preferences、品牌 Profile、通用默认值。

- 只使用 Manifest 声明的字段；Profile 保存公开品牌事实，Preferences 保存个人工作偏好。
- `required: true` 字段缺失时，按 Manifest 的问题配置向用户提出一个聚焦问题；用户明确同意后再保存回答。
- 报错提供可复制的 `context_id`、字段路径与来源，诊断内容避开秘密、完整私人路径和原始配置。

## 通用反馈闭环

用户在 Skill 驱动任务中提出修改意见时，继续当前产物前必须执行：

1. 先判断意见是 `task-specific`（仅本次）还是 `reusable`（可跨任务复用）。
2. `task-specific` 只修改当前任务，不改 Skill。
3. `reusable` 先确定作用域：领域规则先更新对应 canonical Skill；适用于所有 Skill 的规则先更新共享规范。
4. 完成规则更新、版本、lint 与分发核验后，再把修改应用到当前任务。
5. `reusable` 修改会使此前的“确认”“继续”“发吧”失效；完成当前产物修改和回读后必须停下，等待用户下一步指示，不自动进入发布、提交或其他外部写入。
