description	Create a well-structured GitHub PR with proper branching, testing, formatting, and documentation. Use when the user says "create a PR", "make a PR", "open a pull request", or wants to submit changes for review. Handles the full workflow: branch creation, implementation, testing, formatting, committing, and PR creation with comprehensive descriptions.

Create a GitHub Pull Request

Overview

This skill guides the complete PR workflow from branch creation to PR submission for the LabLink project.

Step 1: Branch Setup

Pull latest main

git checkout main
git pull origin main

Create feature branch

Use a descriptive branch name following the pattern: {user}/{type}-{description}

Types:

• feat or feature - New functionality
• fix - Bug fixes
• refactor - Code restructuring
• docs - Documentation updates
• test - Test additions/improvements
• chore - Maintenance tasks

git checkout -b andrew/feat-descriptive-name

Step 2: Understand the Problem

Before coding, clearly identify:

1. Core problem: What issue are we solving?
2. Scope: What files/modules will be affected?
3. Approach: What's the implementation strategy?
4. Edge cases: What scenarios need special handling?

If there's an associated GitHub issue, fetch it for context:

gh issue view <issue-number>

Step 3: Implement Changes

• Make focused, incremental changes
• Follow existing code patterns and style (see CLAUDE.md)
• Add type hints for public functions
• Use Google-style docstrings
• Consider backwards compatibility

Step 4: Write Tests

Location

Tests go in the tests/ directory within each package:

• packages/allocator/tests/
• packages/client/tests/

Requirements

• Cover all new functionality
• Test edge cases and error conditions
• Test both success and failure paths
• Minimum 90% coverage (enforced in CI)

Test file naming

• test_{module_name}.py for module tests

Step 5: Lint and Format

Run linting checks:

# Check linting
ruff check packages/allocator packages/client

# Auto-fix lint issues
ruff check --fix packages/allocator packages/client

Step 6: Run Tests

Run tests per package:

# Allocator tests
cd packages/allocator && PYTHONPATH=. pytest

# Client tests
cd packages/client && PYTHONPATH=. pytest

# With coverage
cd packages/allocator && PYTHONPATH=. pytest --cov
cd packages/client && PYTHONPATH=. pytest --cov

Step 7: Commit Changes

Commit structure

Make well-structured, atomic commits:

• Each commit should be a logical unit of work
• Write clear, descriptive commit messages
• Use conventional commit format

Commit message format

<type>: <short description>

<optional longer description>

Types: feat, fix, refactor, test, docs, chore

Step 8: Push to GitHub

git push -u origin <branch-name>

Step 9: Create Pull Request

Create the PR

gh pr create --base main --title "<descriptive title>" --body "$(cat <<'EOF'
## Summary
<1-3 bullet points describing the changes>

## Changes Made
- <detailed list of changes>

## Testing
- <describe test coverage>
- <note any manual testing done>

## Design Decisions
- <explain key architectural choices>
- <note trade-offs considered>

## Related Issues
Closes #<issue-number> (if applicable)

)"

If updating an existing PR

Fetch current PR description:

gh pr view <pr-number> --json body -q '.body'

Update PR description:

gh pr edit <pr-number> --body "<new body>"

Fetch associated issue for context

If an issue is linked:

gh issue view <issue-number>

Use issue context to ensure PR description addresses all requirements.

PR Description Checklist

• Summary clearly explains the "what" and "why"
• All significant changes are documented
• Breaking changes highlighted
• Test coverage described
• Design decisions explained with reasoning
• Related issues linked

Quick Reference Commands

# Branch setup
git checkout main && git pull origin main
git checkout -b andrew/feat-my-feature

# Lint
ruff check packages/allocator packages/client
ruff check --fix packages/allocator packages/client

# Test
cd packages/allocator && PYTHONPATH=. pytest
cd packages/client && PYTHONPATH=. pytest

# Find changed files
git diff --name-only $(git merge-base origin/main HEAD)

# Commit
git add <files>
git commit -m "feat: description"

# Push and create PR
git push -u origin <branch>
gh pr create --base main --title "Title" --body "Description"

# View/edit existing PR
gh pr view <number>
gh pr edit <number> --body "New description"

# View linked issue
gh issue view <number>

CI Checks

PRs trigger the following CI checks:

• Lint: ruff check on both packages
• Tests: pytest with coverage on both packages
• Docker build: Verify dev images build and run correctly
• Terraform: Validate client VM Terraform plans

Ensure all checks pass before requesting review.
