Claude Command: Update PR Summary

Claude Command: Update PR Summary

Update PR description with automatically generated summary based on complete changeset.

Usage

/update-pr-summary <pr_number>    # Update PR description
/update-pr-summary 131            # Example: update PR #131

Workflow Steps

1. Fetch PR Information:

   • Get PR details using gh pr view <pr_number> --json title,body,baseRefName,headRefName
   • Identify base branch and head branch from PR metadata

2. Analyze Complete Changeset:

   • IMPORTANT: Analyze ALL committed changes in the branch using git diff <base-branch>...HEAD
   • PR description must describe the complete changeset across all commits, not just the latest commit
   • Focus on what changed from the perspective of someone reviewing the entire branch
   • Ignore unstaged changes

3. Generate PR Description:

   • Create brief summary (1 sentence or few words)
   • Add few bullet points of key changes
   • For significant changes, include before/after code examples in PR body
   • Include inline markdown links to relevant code lines when helpful (format: [src/auth.py:42](src/auth.py#L42))
   • For config/API changes, use mcp__tavily__tavily_search to verify information and include source links inline
   • Never include test plans in PR descriptions

4. Update PR Title (if needed):

   • Title should start with capital letter and verb
   • Should NOT start with conventional commit prefixes (e.g. "fix:", "feat:")

5. Update PR:

   • Use gh pr edit <pr_number> with --body (and optionally --title) to update the PR
   • Use HEREDOC for proper formatting:

   gh pr edit "$(
     cat << 'EOF'
   [PR description here]
   EOF
   )" < pr_number > --body
   

PR Description Format

[Brief summary in 1 sentence or few words]

- [Key change 1 with inline code reference if helpful]
- [Key change 2 with source link if config/API change]
- [Key change 3]

[Optional: Before/after code examples for significant changes]

Examples

Example 1: Config/API Change with Source Links

Update Claude Haiku to version 4.5

- Model ID: claude-3-haiku-20240307 → claude-haiku-4-5-20251001 ([source](https://docs.anthropic.com/en/docs/about-claude/models/overview))
- Pricing: $0.80/$4.00 → $1.00/$5.00 per MTok ([source](https://docs.anthropic.com/en/docs/about-claude/pricing))
- Max output: 4,096 → 64,000 tokens ([source](https://docs.anthropic.com/en/docs/about-claude/models/overview))

Example 2: Code Changes with File Links

Refactor authentication to use async context manager

- Replace synchronous auth flow with async/await pattern in [src/auth.py:15-42](src/auth.py#L15-L42)
- Add context manager support for automatic cleanup

Before:

```python
def authenticate(token):
    session = create_session(token)
    return session
```

After:

```python
async def authenticate(token):
    async with create_session(token) as session:
        return session
```

Example 3: Simple Feature Addition

Add user profile export functionality

- Export user data to JSON format in [src/export.py:45-78](src/export.py#L45-L78)
- Add CLI command `/export-profile` in [src/cli.py:123](src/cli.py#L123)
- Include email, preferences, and activity history in export

Error Handling

Pre-Analysis Verification:

• Verify PR exists and is accessible
• Check tool availability (gh auth status)
• Confirm authentication status

Common Issues:

• Invalid PR number → List available PRs
• Missing tools → Provide setup instructions
• Auth issues → Guide through authentication
