Prerequisites

• Git remotes configured (use git remote -v to check):
  • upstream repository (openharmony/graphic_graphic_2d)
  • user's fork (username/graphic_graphic_2d)
• Gitcode MCP tools available (if not installed, install from this repo)
• Build passes successfully

Workflow

1. Stage and Commit Changes

# Reset any staged changes and stage everything together
git reset HEAD .
git add .
git status

# Create a new branch from current branch
git checkout -b feature/descriptive-branch-name

# Commit with signoff (required)

Detailed explanation of the change.

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>"

Note: Always use -s flag for signed commits (DCO compliance).

2. Push to Fork

# Push branch to fork (remote 'z')
git push -u z feature/descriptive-branch-name

3. Create Issue

Use gitcode MCP tool to create an issue in the upstream repository:

mcp__gitcode__create_issue
- owner: openharmony
- repo: graphic_graphic_2d
- title: Brief issue title
- body: Detailed issue description with:
  - Summary
  - Problem
  - Solution
  - Impact
  - Files Modified

Example issue body:

## Summary
Brief description of the issue/change.

## Problem
What problem does this solve?

## Solution
How is it solved?

## Impact
- What changes are made?
- Performance impact
- Test results

## Files Modified
- file1.h
- file2.cpp

4. Create Pull Request

Use gitcode MCP tool to create PR in upstream repository:

mcp__gitcode__create_pull_request
- owner: openharmony
- repo: graphic_graphic_2d
- base: master (NOT main - use master)
- head: zhoutianer:feature/descriptive-branch-name
- title: PR title (matches issue title)
- body: Detailed PR description

Critical: Use master as the base branch, not main.

Example PR body:

## Summary
Brief description.

## Problem
What problem does this solve?

## Solution
Technical details of the implementation.

## Impact
- Code quality improvements
- Performance impact
- Test results

## Test plan
- [x] Build passes
- [x] All tests pass
- [x] No new warnings

## Files Modified
- file1.h
- file2.cpp

Closes #<issue-number>

The Closes #<issue-number> at the end automatically links the PR to the issue.

5. Link Issue to PR

Add a comment to the issue referencing the PR:

mcp__gitcode__create_issue_comment
- owner: openharmony
- repo: graphic_graphic_2d
- issue_number: <issue-number>
- body: Link to PR and summary

Example comment:

This issue is addressed by PR #<pr-number>: https://gitcode.com/openharmony/graphic_graphic_2d/merge_requests/<pr-number>

The PR implements:
- Key change 1
- Key change 2

Build passes in X:YY time with all tests passing.

Important Notes

1. Base branch: Always use master, not main
2. Sign commits: Always use git commit -s for DCO compliance
3. Branch naming: Use descriptive names like refactor/feature-name, fix/bug-description
4. Issue-PR linking: Include Closes #<issue-number> in PR body
5. Remote names:
   • gitcode - upstream (openharmony/graphic_graphic_2d)
   • z - fork (zhoutianer/graphic_graphic_2d)

Example Session

# After making code changes
git reset HEAD .
git add .
git checkout -b refactor/color-picker-common-impl
git commit -s -m "refactor: Extract common implementation

- Add HandleColorUpdate to base interface
- Extract CreateColorPickerInfo helper
- Remove ~200 lines of duplication

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>"

git push -u z refactor/color-picker-common-impl

Then use MCP tools to create issue #22224, PR #28311, and link them.

Troubleshooting

PR creation fails with API error (400):

• Check that base branch is master, not main
• Ensure branch was pushed to fork first

Issue not linking to PR:

• Verify Closes #<issue-number> is in PR body
• Check issue number is correct
• Add manual comment to issue if auto-link fails
