1. Detect the base branch via git remote show origin | grep 'HEAD branch'. Run in parallel:

   • git diff <base> --name-only and git diff <base> to understand changes
   • git log <base>..HEAD --oneline to see commit history

2. Review all changes (all commits since base) and write a PR description following this exact markdown format:

## Summary

<1-3 bullet points summarizing what changed and why>

## Changes

<Flat list of 4–7 bullets describing behavior/outcome, not files. One line each.>

Formatting rules

• Wrap code identifiers (function names, class names, filenames, variable names) in backticks.
• Use bullet points (-), not numbered lists.
• Keep bullet points concise — one line each when possible.
• Cap Summary at 3 bullets and Changes at ~7 bullets. If you need more, you're narrating instead of summarizing.
• Describe outcomes, not files. Don't list every added file, resolver, mapper, or test case — group them ("Add resolvers X and Y", "Add integration tests covering …").
• Avoid sub-bullets. Use them only when a bullet genuinely has 2+ distinct sub-concerns that a reviewer must see separately.
• Omit mechanical housekeeping (lockfile updates, worklogs, task specs, trivial imports) unless reviewer-relevant. Fold changesets/dep bumps into one line.
• Do NOT use bold, italic, or other inline formatting beyond backticks.
• Wrap the entire output inside a fenced code block (triple backticks with markdown language tag) so the terminal displays raw markdown that can be copied directly into a GitHub PR description.
