oh-pr-workflow: OpenHarmony PR Lifecycle Workflow

Unified workflow for OpenHarmony GitCode repositories. Five modes:

• Commit only: user says "提交", "commit" → commit with standardized message, stop
• Full PR: user says "创建PR", "提个PR" → commit (if needed) + push + Issue + PR
• Fix Codecheck: user says "修复告警", "修复门禁", "修复codecheck" or provides a PR URL → fetch gate codecheck defects and auto-fix
• Review PR: user says "review pr", "检视pr", "看下这个pr" + PR URL → fetch PR changes to local for review
• Fix Review: user says "修复review", "修复检视意见", "fix review" + PR URL → fetch unresolved review comments and auto-fix

Mode Selection (Quick Reference)

After identifying the mode, verify prerequisites below, then jump directly to the relevant mode section.

Prerequisite: Before executing any mode:

1. GitCode Token must be configured. Check: git config --get gitcode.token

If empty → inform user: "请先配置 GitCode 个人访问令牌：git config --global gitcode.token YOURTOKEN 令牌获取：GitCode 个人设置 → 访问令牌 → 创建（需要 api 和 readapi 权限）" Stop execution.

1. Check if getauthenticateduser MCP tool is available (ToolSearch "getauthenticateduser")

If NOT available → run setup automatically: ``bash bash ~/.claude/skills/oh-pr-workflow/gitcode-mcp/setup.sh `` Then inform user: "GitCode MCP 已自动安装，请重启 Claude Code 会话以加载新工具。" Stop execution (new session needed for MCP tools to load).

1. Both checks pass → proceed with the workflow.

Scope

This workflow applies to ALL GitCode repository submissions, not just the current working directory. When submitting to a different repo (e.g., cloning a separate repo to /tmp for a PR), the same rules MUST be followed:

• Commit message format (type(scope): title + Issue + Signed-off-by + Co-Authored-By)
• Issue must exist BEFORE writing it into commit message (create if needed)
• Never reference an Issue URL without first verifying or creating it via API

Commit Message Format

See references/commit-format.md for full spec (format, types, rules, examples).

HARD LIMIT: The first line (title) of the commit message MUST NOT exceed 49 characters (including type(scope): prefix). Count characters BEFORE committing. If over 49, shorten it. Example: fix(aptool): add ABC metadata checks (37 chars) ✓ Counter-example: fix(aptool): add defensive checks for ABC metadata lookup (58 chars) ✗

Remote Detection

Never assume remote names. Run git remote -v and classify by owner:

• openharmony → UPSTREAM (PR target, Issue creation)
• Other → FORK (push target, PR head)

Both must exist. Missing fork → prompt user. Ambiguous → ask user to select.

Email Resolution

Get email for Signed-off-by line. Priority:

1. Memory cache: check if usergitcodeemail.md exists in auto-memory. If found, use email field directly.
2. MCP API: call getauthenticateduser tool (no parameters). Extract email field. Save to memory as usergitcodeemail.md with type user.
3. Git config: git config user.email as fallback.
4. None: prompt user to configure.

Issue Detection

Determines which Issue to use for commit message and PR. Shared by both modes.

Input: user may specify --issue N or --issue URL.

Algorithm:

1. User specified Issue → validate with get_issue, use if valid
2. Scan git log {upstreamremote}/{targetbranch}..HEAD for existing Issue URLs

- Regex: Issue:\s*https://gitcode\.com/[^/]+/[^/]+/issues/(\d+) - If found → reuse the earliest match

1. Not found → auto-create via create_issue on upstream repo

- Title: derived from branch name or commit diff - Body: use references/issue_template.md, fill from git diff context

Issue URL format: https://gitcode.com/{upstreamowner}/{upstreamrepo}/issues/{number}

Mode 1: Commit Only

Trigger: user wants to commit without creating PR.

Step 1: Check uncommitted changes
  git status --porcelain

Step 2: Resolve email
  Follow Email Resolution above

Step 3: Determine Issue
  Follow Issue Detection above (target_branch defaults to master)

Step 4: Generate commit message
  - Title: MUST be ≤49 chars (count before committing!), Claude generates from diff or user provides
  - Body: Issue URL + Signed-off-by + Co-Authored-By: Agent

Step 5: Stage files
  a. Identify files to commit:
     - Files that Claude created or modified in this session → always include
     - Other changed files in working tree → need user confirmation
  b. Filter out files that should NEVER be committed:
     Exclude patterns:
       - .idea/*, .vscode/*, .claude/*, .DS_Store
       - .env, .env.*, credentials*, *secret*
       - out/*, build/*, *.o, *.so, *.a, *.pyc, __pycache__/
       - report.json, rules.txt, *.log
       - Any file matched by .gitignore
  c. If there are files beyond what Claude modified:
     Present to user: "以下文件也有变更，是否一起提交？" + file list
     User selects which to include
  d. git add {final file list} — always add specific files by name
     NEVER use "git add ." or "git add -A"

Step 6: Pre-commit codecheck
  If oh-precommit-codecheck skill is available, run it on staged files:
    Invoke: /oh-precommit-codecheck
  If defects found:
    - Present defects to user
    - Ask: "发现代码告警，是否先修复再提交？"
    - User confirms fix → fix defects, re-stage, re-run codecheck
    - User skips → proceed to commit (warn that gate may fail)
  If no defects or skill not available → proceed

Step 7: Commit
  - git commit with formatted message (use HEREDOC for multi-line)
  - Output: commit hash, linked Issue

Commit command template:

git commit -m "$(cat <<'EOF'
type(scope): title here

Issue: https://gitcode.com/owner/repo/issues/N
Signed-off-by: Name <email>
Co-Authored-By: Agent
EOF
)"

Mode 2: Full PR

Trigger: user wants to create a PR.

Input: --target branch (optional, default: master)

Step 1: Check status & detect remotes
  git status, git remote -v
  Identify upstream and fork
  Determine target branch

Step 2: Handle uncommitted changes
  git status --porcelain
  Has changes → execute Commit Only mode (Steps 2-7)

Step 3: Push to fork
  git push -u {fork_remote} {current_branch}

Step 4: Check existing PR
  MCP list_pull_requests (upstream owner/repo)
  Search results for current branch name
  Found → inform user "PR !{number} already exists", stop
  Not found → continue

Step 5: Determine Issue
  Follow Issue Detection above

Step 6: Create PR
  Read .gitee/PULL_REQUEST_TEMPLATE.zh-CN.md from repo (prioritize repo template if exists)
  Fill template with bilingual content (Chinese + English per item, NOT repeated blocks):
    - Issue: full URL https://gitcode.com/{upstream_owner}/{upstream_repo}/issues/{number}
      (NEVER use #{number} shorthand — always use the full Issue URL)
    - 描述/Description, 原因/Reason, 修改方案/Scheme: write bilingual per item.
      Format each point as "中文 / English" on the same bullet, e.g.:
        - `FindRecordByName` 匹配失败时无日志 / No log output when match fails
      Do NOT write all Chinese first then repeat all English — interleave per item.
    - Checklist: intelligently check items based on change scope
  If no template found in repo, use a simple bilingual structure with Issue URL,
  Description, Reason, Scheme sections.
  MCP create_pull_request:
    owner: {upstream_owner}
    repo: {upstream_repo}
    title: concise summary from commit messages
    head: {fork_owner}:{current_branch}
    base: {target_branch}
    body: filled template content (bilingual)
  Output: PR URL, linked Issue number

Step 7: Trigger gate CI
  After PR is created, post comment to trigger build:
  MCP create_pr_comment:
    owner: {upstream_owner}
    repo: {upstream_repo}
    pull_number: {pr_number from Step 6}
    body: "start build"
  Output: inform user that gate CI has been triggered

Example successful run:

git remote -v → openharmony (upstream), origin (fork)
git status → 2 files changed
→ Commit: fix(napi): add null check [32 chars] ✓
→ Push: origin/fix-null-check
→ Issue: #1985 created on openharmony/arkui_napi
→ PR: !2610 created (zhuheng_z:fix-null-check → master)
→ Comment: "start build" posted, gate CI triggered

Mode 3: Fix Codecheck

Trigger: user says "修复告警", "修复门禁", "修复codecheck", "fix codecheck", or provides a GitCode PR URL asking to fix codecheck issues.

Input: A GitCode PR URL like https://gitcode.com/{owner}/{repo}/pull/{number}

Step 1: Parse PR URL and get PR details
  Extract owner, repo, pull_number from the URL
  Regex: https://gitcode\.com/([^/]+)/([^/]+)/pull/(\d+)
  MCP get_pull_request(owner, repo, pull_number) to get:
    - head.ref: source branch
    - head.sha: head commit SHA
    - head.repo.full_name: fork repo (e.g., "zhuheng_z/arkui_napi")

Step 2: Ensure PR code is checked out locally
  a. Check if head commit exists locally:
       git cat-file -t {head.sha} 2>/dev/null
  b. Check if current branch matches PR branch:
       git branch --show-current == head.ref ?
  c. Decision:
     - Current branch matches AND head SHA matches → code is local, proceed
     - Head SHA exists but wrong branch → git checkout {head.ref}
     - Head SHA not local → fetch and checkout:
         Extract head_owner from head.repo.full_name
         git remote add pr-fix-{head_owner} https://gitcode.com/{head_owner}/{repo}.git 2>/dev/null || true
         git fetch pr-fix-{head_owner} {head.ref}
         git checkout -b fix/pr-{pull_number} FETCH_HEAD
  d. Record original branch for later return

Step 3: Get PR comments and find failed gate check
  MCP list_pr_comments(owner, repo, pull_number, per_page=100)
  Search for the first comment containing "代码门禁未通过"
  If not found → inform user "No failed gate check found", stop

Step 4: Extract CI eventId and taskId from the failed comment body
  ciEventId: regex /detail/([a-f0-9]+)/runlist  (this is the CI event ID)
  taskId:    regex taskId=(MR_[a-f0-9]+)
  date:      extract from comment created_at (YYYY-MM-DD)

Step 5: Get codecheck UUID from CI event info
  IMPORTANT: The defect detail API needs the codecheck UUID, NOT the CI event ID.
  Fetch CI event info:
    GET https://dcp.openharmony.cn/api/codecheckAccess/ci-portal/v1/event/{ciEventId}
  Extract codecheck UUID from response:
    response.data.codeCheckSummary[0].uuid → this is the codecheckEventId
  Use codecheckEventId (not ciEventId) for the defect API.

Step 6: Fetch all defects
  Run: bash ~/.claude/skills/oh-pr-workflow/scripts/fetch_gate_defects.sh <codecheckEventId> <taskId> <date>
  This auto-paginates and outputs a JSON array to stdout
  Parse the JSON to get the defect list

Step 7: Summarize defects
  Present a summary table to user:
    - Total defect count
    - Breakdown by rule (e.g., G.FMT.11-CPP: 56, G.FMT.04-CPP: 48, ...)
    - Breakdown by file
  Ask user to confirm before proceeding with fixes

Step 8: Auto-fix defects
  For each defective file:
    a. Read the file
    b. For each defect in that file, understand the rule and fix it:
       - G.FMT.04-CPP (one statement per line): split multi-declarations
       - G.FMT.11-CPP (braces): add {} around single-line if/for/while/else
       - G.FMT.05-CPP (line width): break lines over 120 chars
       - G.NAM.03-CPP (naming): rename to match convention
       - G.EXP.35-CPP (nullptr): replace NULL/0 with nullptr
       - G.EXP.41-CPP (loop variable): restructure loop
       - G.FUN.01-CPP (function size): cannot auto-fix, report to user
       - Other rules: read the defectContent, apply best-effort fix
    c. Edit the file with fixes

Step 9: Verify fixes (optional)
  If oh-precommit-codecheck skill is available, run local codecheck on fixed files
  Report any remaining issues

Mode 4: Review PR

Trigger: user says "review pr", "review这个pr", "看下这个pr", "检视pr", or provides a PR URL with review intent.

Input: A GitCode PR URL like https://gitcode.com/{owner}/{repo}/pull/{number}

Step 1: Parse PR URL
  Extract owner, repo, pull_number from the URL
  Regex: https://gitcode\.com/([^/]+)/([^/]+)/pull/(\d+)

Step 2: Get PR details via MCP
  MCP get_pull_request(owner, repo, pull_number)
  From response extract:
    - head.ref: source branch name (e.g., "fix/strdup-free-mismatch")
    - head.sha: head commit SHA
    - head.repo.full_name: fork full name (e.g., "yewei0794/arkui_napi")
    - head.user.login: PR author login
    - base.ref: target branch (e.g., "master")
    - base.sha: base commit SHA
    - title, body, state, labels

Step 3: Get PR commits and files via MCP (precise, no git fetch needed)
  MCP list_pr_commits(owner, repo, pull_number)
    → exact commit list with SHA and message
  MCP list_pr_files(owner, repo, pull_number)
    → exact changed file list with filename, additions, deletions, patch

Step 4: Present PR summary
  - PR title, author, head branch → base branch
  - Commit list (from Step 3)
  - Changed files with +/- stats (from Step 3)

Step 5: Fetch PR code to local
  Always fetch to local so user can browse the code after review:
    a. Record current branch: git branch --show-current
    b. Stash if dirty: git stash (if needed)
    c. Extract head_owner from head.repo (e.g., "yewei0794")
    d. git remote add pr-review-{head_owner} https://gitcode.com/{head_owner}/{repo}.git 2>/dev/null || true
    e. git fetch pr-review-{head_owner} {head.ref}
    f. git checkout -b review/pr-{pull_number} FETCH_HEAD
  Use patch data from Step 3 for the review analysis itself (faster),
  but the local branch ensures user can inspect files afterwards.

Step 6: Perform code review
  For each changed file:
    a. Use patch from list_pr_files for diff analysis
    b. Read full file from local checkout when deeper context is needed
    c. Identify issues: bugs, style, security, performance, logic errors
    d. Present review comments organized by file with line references
  After presenting all review findings, ask the user which comments (if any)
  should be posted as line-level diff comments on the PR.
  If the user confirms specific comments → post them using the Line-Level
  Review Comment API described below.

Step 7: Keep local branch, inform user
  After review, switch back to original branch but DO NOT delete the review branch:
    git checkout {original_branch}
    git stash pop (if stashed)
  Inform user:
    "Review 完成。PR 代码保留在本地分支 review/pr-{pull_number}，你可以随时切换查看。
     清理命令: git branch -D review/pr-{pull_number} && git remote remove pr-review-{head_owner}"

Mode 5: Fix Review

Trigger: user says "修复review", "修复检视意见", "fix review", or provides a PR URL with intent to fix review comments.

Input: A GitCode PR URL like https://gitcode.com/{owner}/{repo}/pull/{number}

Step 1: Parse PR URL and get PR details
  Extract owner, repo, pull_number from the URL
  MCP get_pull_request(owner, repo, pull_number) to get:
    - head.ref, head.sha, head.repo.full_name

Step 2: Ensure PR code is checked out locally
  Same logic as Mode 3 Step 2:
    - Check head SHA exists locally + current branch matches
    - If not → fetch and checkout

Step 3: Fetch diff data and review comments
  a. Get PR changed files with diff hunks (needed for file path mapping):
     MCP list_pr_files(owner, repo, pull_number)
     For each file, parse hunk headers from patch.diff:
       Regex: @@ -(\d+),?(\d*) \+(\d+),?(\d*) @@
     Build a line-to-file mapping:
       For each file, each hunk defines a new_line range:
         new_start to new_start + new_count - 1 → filename

     Worked example:
       A review comment has diff_position.start_new_line = 2650.
       list_pr_files returns ark_native_engine.cpp with hunk header:
         @@ -2638,15 +2640,31 @@
       Parse: new_start=2640, new_count=31 → range is [2640, 2670].
       Check: 2650 falls within [2640, 2670].
       Result: comment maps to ark_native_engine.cpp, line 2650 in the new file.

       If another file utils.cpp has hunk @@ -100,10 +100,12 @@ (range [100, 111]),
       2650 does NOT fall in [100, 111], so utils.cpp is ruled out.

  b. Get review comments:
     MCP list_pr_comments(owner, repo, pull_number, comment_type="diff_comment", per_page=100)
     Filter for unresolved only: resolved == false
     Extract from each:
       - user.login: reviewer name
       - body: review comment content
       - diff_position.start_new_line / end_new_line: line number in new file
       - discussion_id: for grouping replies

  c. Map each comment to its file:
     IMPORTANT: GitCode API does NOT return a `path` field in diff_comment JSON.
     Use the line-to-file mapping from step (a) to determine the file:
       For each comment, find the file whose hunk range contains
       diff_position.start_new_line → that is the file the comment belongs to.

  d. Outdated detection (after force-push, diff line numbers shift):
     For each review comment, compare its diff_position line against the current
     diff's hunk ranges:
       - Line falls within a current hunk range → comment is still ACTIVE
       - Line out of range for all hunks → comment is OUTDATED
     Present outdated comments separately (greyed out) so user can confirm skipping.

Step 4: Present review comments and proposed fixes to user
  Group comments into ACTIVE and OUTDATED based on Step 3(d) outdated detection.

  For OUTDATED comments:
    Show as "~~已过期~~" with original content, no fix proposed.

  For ACTIVE comments:
    - Reviewer: {user.login}
    - File: {mapped filename from Step 3(c)}
    - Line: {diff_position.start_new_line}
    - Comment: {body}
    - Proposed fix: Claude reads the file at that line, analyzes the comment, shows before/after diff

  *** HARD GATE: STOP HERE AND WAIT FOR USER CONFIRMATION ***
  Do NOT proceed to Step 6 until the user explicitly confirms.
  Present all proposed fixes and ask: "以上修复方案是否可以执行？"
  User may:
    - Confirm all → proceed to Step 6
    - Confirm some, reject others → adjust and re-present
    - Reject all → stop

Step 5: Apply confirmed fixes
  Only apply fixes the user confirmed:
    a. Read the target file
    b. Apply the fix at the indicated line
    c. Edit the file

Step 6: Squash into original commit and push
  IMPORTANT: Always squash fix into original commit, never create separate commit.
    git add {fixed files}
    git commit --amend --no-edit

  *** CONFIRM BEFORE FORCE-PUSH ***
  Inform user: "将 squash 进原始 commit 并 force-push 到 {fork_remote}/{branch}。确认？"
  Wait for user confirmation before proceeding. Do NOT force-push without explicit approval.

    git push --force {fork_remote} {branch}

Step 7: Trigger rebuild
  MCP create_pr_comment(owner, repo, pull_number, body="start build")

Error Handling (Mode 5: Fix Review)

• No unresolved review comments: inform user "No unresolved review comments found"
• Review comment unclear: present the comment to user and ask for guidance
• File not found locally: warn and skip
• Cannot determine fix from comment: report to user with context for manual fix

Error Handling (Mode 4: Review PR)

• PR URL not provided: ask user for the PR URL
• PR not found: inform user, check if PR number is correct
• head/base fields empty: fallback to listprcommits + listprfiles for review data
• Fetch fails: the PR source fork may be private or deleted; use API patches if available
• Local repo is different repo: warn if current repo doesn't match PR's repo
• Dirty working tree: warn user about uncommitted changes, suggest stash before switching branches

Error Handling (Mode 3: Fix Codecheck)

• PR URL not provided: ask user for the PR URL
• No failed gate found: inform user, suggest checking if gate passed
• DCP API returns 500: inform user DCP service may be down, show the eventId/taskId for manual retry
• Defect in file not in local repo: warn and skip (PR may be from a different branch/repo)
• Cannot auto-fix: report the defect to user with file:line and rule description

Error Handling (General)

• MCP not configured: warn and stop immediately
• No upstream remote: prompt user to add openharmony remote
• No fork remote: prompt user to fork the repo
• PR already exists: only push, inform user with PR number
• Issue creation fails: warn, continue with commit (Issue line omitted)
• Push fails: show error, suggest checking remote/permissions
• Commit message title > 49 chars: MUST shorten before committing — this is a HARD LIMIT (applies to commit message title only, NOT PR title). Always count characters including the type(scope): prefix before running git commit
• No changes to commit: skip commit in PR mode, stop in commit mode
• Email not found: prompt user to configure git email or GitCode token

Common Mistakes (Anti-Patterns)

These are critical errors that have caused real failures. NEVER make these mistakes:

1. NEVER confuse ciEventId with codecheckEventId (Mode 3)

The defect detail API needs the UUID from codeCheckSummary[0].uuid, NOT the CI event ID extracted from the gate comment URL. The CI event ID (from /detail/{id}/runlist) is only used to fetch the codecheck summary — the actual defect query requires the uuid field returned inside codeCheckSummary.

1. NEVER use best-effort fix for rules you do not recognize (Mode 3)

If a codecheck rule is not listed in Step 8's known rules (G.FMT.04-CPP, G.FMT.11-CPP, etc.), do NOT attempt a speculative fix. Instead, report the defect to the user with the rule ID, file:line, and defectContent so they can decide how to handle it.

1. NEVER assume diffposition.startnew_line is a global offset (Mode 5)

diffposition.startnewline is a line number within the specific file's new version, not a global position across all files. You MUST use the line-to-file mapping from listpr_files hunk headers to determine which file the line belongs to.

1. NEVER force-push without user confirmation (Mode 5)

git push --force is destructive. Always show the user what will be pushed and to where, then wait for explicit confirmation.

1. NEVER create a separate commit for review fixes (Mode 5)

Review fixes must always be squashed into the original commit via git commit --amend --no-edit. Creating a new commit pollutes the PR history and may violate upstream merge policies.

GitCode MCP Tools Used

Note: This section is a reference catalog. You do not need to read it during normal execution — the specific MCP tools to call are listed inline within each mode's steps above.

Core workflow tools:

• getauthenticateduser — get current user email for Signed-off-by
• create_issue — create Issue on upstream repo
• get_issue — validate user-specified Issue exists
• listpullrequests — check for existing PR
• createpullrequest — create PR from fork to upstream
• getpullrequest — get PR details (head.ref, head.sha, head.repo, base.ref, base.sha)
• listprcommits — list exact commits in a PR
• listprfiles — list changed files with additions/deletions/patch
• listprcomments — list PR comments with optional commenttype filter (diffcomment/pr_comment)
• createprcomment — post comment on PR (general or line-level with path+position)
• deleteprcomment — delete a PR comment by note_id

Additional tools available:

• updatepullrequest — update PR title/body/state/base
• mergepullrequest — merge PR (merge/squash/rebase)
• submitprreview — approve PR review
• submitprtest — mark PR test passed
• updateprreviewers — assign reviewers
• updateprtesters — assign testers
• updateprlabels — add/remove PR labels
• prlinkissues — link issues to PR
• listproperation_logs — PR operation history

• listprreactions / createprreaction — PR emoji reactions
• listissuereactions / createissuereaction — issue emoji reactions
• create_release — create repository release

Line-Level Review Comment

The MCP createprcomment tool supports both general and line-level comments:

General comment: createprcomment(owner, repo, pullnumber, body="...") Line-level comment: createprcomment(owner, repo, pullnumber, body="...", path="file.cpp", position=N)

Determining position:

• position is the line number in the unified diff, NOT the file line number.
• For new files (100% addition): diff line number == file line number.
• For modified files: count lines sequentially within the file's unified diff

(the @@ header line is not counted; first content line after @@ is position 1; positions are cumulative across all hunks in the file).

• Use the patch field from listprfiles to compute the correct position.

Deleting a comment: deleteprcomment(owner, repo, commentid=NOTEID)
