Gitcode Pr

GitCode PR Workflow for OpenHarmony

Handles complete GitCode PR submission for OpenHarmony repositories with intelligent remote detection and issue-PR linking. Use the gitcode mcp. If gitcode mcp is not present, warn the user and terminate the skill immediately.

Intelligent Remote Detection

Identification Algorithm

Never assume remote names. Use this algorithm to identify upstream and fork:

# Step 1: List all remotes
git remote -v

# Step 2: Parse each remote
for remote in $(git remote); do
  url=$(git remote get-url $remote)
  
  # Parse owner from URL
  # Format: https://gitcode.com/<owner>/<repo> or https://gitcode.com/<owner>/<repo>.git
  if [[ "$url" =~ https://gitcode\.com/([^/]+)/(.+) ]]; then
    owner="${BASH_REMATCH[1]}"
    repo=$(echo "${BASH_REMATCH[2]}" | sed 's/\.git$//')
    
    # Determine type
    if [ "$owner" = "openharmony" ]; then
      echo "$remote: UPSTREAM ($owner/$repo)"
    else
      echo "$remote: FORK ($owner/$repo)"
    fi
  fi
done

Remote Classification

Decision Matrix

User Prompting

When remote is ambiguous, prompt user:

I found these GitCode remotes:

- **remote_name**: owner/repo (UPSTREAM/FORK)

Which remote should I use for:
- Pushing changes?
- Creating the PR?

Please specify the remote name, or press Enter to use [default].

Workflow

Follow this workflow when user requests PR submission:

1. Check Current State

Check git status and branch:

git status
git branch --show-current
git remote -v

Determine:

• What is the current branch name?
• Identify upstream and fork remotes using algorithm above

2. Check if PR Exists

Use gitcode_list_pull_requests to check for existing PRs:

# Get upstream owner/repo (parse from upstream remote URL)
UPSTREAM_REMOTE=$(detect_upstream_remote)
UPSTREAM_URL=$(git remote get-url $UPSTREAM_REMOTE)
# Parse: openharmony/security_code_signature from URL

# List PRs for upstream repo
gitcode_list_pull_requests --owner $UPSTREAM_OWNER --repo $UPSTREAM_REPO

# Search for PR with matching branch name and owner name

If PR exists: Only push to fork and inform user.

git push -u $FORK_REMOTE <branch-name>

If PR does not exist: Continue to steps 4-6 to create issue and PR.

3. Create Issue

Load issue template and create issue:

1. Read issue template: references/issue_template.md
2. Fill in template fields based on context (commit messages, changed files, etc.)
3. Use gitcode_create_issue with upstream owner/repo

Note: Use commit message and git diff to generate issue description automatically.

4. Push to Fork

Push to your fork (the detected fork remote):

git push -u $FORK_REMOTE <branch-name>

5. Create PR from Fork to Upstream

Load PR template from upstream repository and create PR linking to issue:

1. Get upstream PR template:

   # Try local copy first
   if [ -f .gitee/PULL_REQUEST_TEMPLATE.zh-CN.md ]; then
     cat .gitee/PULL_REQUEST_TEMPLATE.zh-CN.md
   else
     # Fetch from upstream
     git fetch $UPSTREAM_REMOTE master
     git show $UPSTREAM_REMOTE/master:.gitee/PULL_REQUEST_TEMPLATE.zh-CN.md
   fi
   

2. Fill template: Follow the direction in the template.

3. Create PR using gitcode_create_pull_request:

   IMPORTANT: For cross-repo PRs, the head parameter format is CRITICAL.

   • Must be exactly: <fork-owner>:<branch-name> (no extra prefixes)
   • GitCode API strictly validates this format for cross-fork PRs

   Parameters:

   • owner: Upstream owner (e.g., openharmony)
   • repo: Upstream repo (e.g., security_code_signature)
   • title: Follow commit message format
   • head: <fork-owner>:<branch-name> (from fork remote parsing)
   • base: Target branch on upstream (typically master or main)
   • body: Template content with issue reference

Example:

# After detection
UPSTREAM_OWNER="openharmony"
UPSTREAM_REPO="security_code_signature"
FORK_OWNER="someone"
FORK_REMOTE="fork"

gitcode_create_pull_request \
  --owner $UPSTREAM_OWNER \
  --repo $UPSTREAM_REPO \
  --title "fix(code_signature): add null check for buffer pointer" \
  --head "$FORK_OWNER:$BRANCH_NAME" \
  --base "master" \
  --body "$(cat .gitee/PULL_REQUEST_TEMPLATE.zh-CN.md | \
    sed 's/^### 关联的issue：$/### 关联的issue：\n#$ISSUE_NUMBER/')"

Templates

Upstream PR Template

Located at .gitee/PULL_REQUEST_TEMPLATE.zh-CN.md in the upstream repository.

Local Issue Template

See references/issue_template.md for standard issue format.

Key sections:

• 问题描述: What is the problem or feature request?
• 复现步骤: For bug reports (if applicable)
• 预期行为: What should happen?
• 实际行为: What actually happens?
• 环境信息: Any relevant environment details

Remote URL Parsing

Parse owner and repo from remote URLs:

# Function to parse GitCode URL
parse_gitcode_url() {
  local url="$1"
  
  # Remove .git suffix if present
  url=$(echo "$url" | sed 's/\.git$//')
  
  # Extract owner and repo
  if [[ "$url" =~ https://gitcode\.com/([^/]+)/(.+) ]]; then
    echo "${BASH_REMATCH[1]}|${BASH_REMATCH[2]}"
  fi
}

# Usage
result=$(parse_gitcode_url "https://gitcode.com/openharmony/security_code_signature")
owner="${result%%|*}"
repo="${result##*|}"
# owner=openharmony, repo=security_code_signature

Issue Reference in PR Template

In .gitee/PULL_REQUEST_TEMPLATE.zh-CN.md, fill in issue reference:

### 关联的issue：
#123

The PR will auto-close issue #123 when merged.

GitCode MCP Tools

Use these tools for GitCode operations:

• gitcode_list_pull_requests - Check existing PRs (use upstream owner/repo)
• gitcode_get_pull_request - Get PR details
• gitcode_create_pull_request - Create new PR (head points to fork)
• gitcode_update_pull_request - Update existing PR
• gitcode_create_issue - Create new issue (use upstream owner/repo)
• gitcode_get_issue - Get issue details

Error Handling

• Authentication failure: Check if GitCode token is configured
• Branch not found on fork: Push to fork first before creating PR
• PR already exists: Inform user and provide link, don't create duplicate
• No upstream remote: Ask user to configure upstream remote (owner=openharmony)
• No fork remote: Ask user which remote to push to, or if they need to fork first
• Multiple non-openharmony remotes: Ask user to select which is their fork
• PR template not found: Check if .gitee/PULL_REQUEST_TEMPLATE.zh-CN.md exists upstream
• Owner/repo parsing error: Validate remote URL format

Context Gathering

When creating issue or PR, gather from:

• git log -1 - Last commit message
• git diff HEAD~1 - Changed files and diff
• Branch name - For feature context
• User input - Additional description if provided
• git remote -v - All remotes and their URLs
• Remote parsing - Upstream owner/repo and fork owner/repo
