summary

name	summary
description	Summarize current branch changes against a base branch. Use when the user asks for a branch summary, change summary, release-style summary, or `/summary` with an optional base branch.

Branch Change Summary

Use this workflow when the user wants a factual summary of branch changes.

Base Branch

• Use the user-provided base branch when present.
• Default to main when no base branch is provided.

Workflow

1. Identify the current branch with git branch --show-current.
2. Inspect commits with git log origin/<base>..HEAD --oneline.
3. Inspect changed files with git diff origin/<base>...HEAD --name-status.
4. Inspect the full diff with git diff origin/<base>...HEAD.
5. Check the surrounding codebase when needed to understand how the changes fit.
6. Produce a concise summary focused on user-visible behavior, structural changes, refactors, tests, and docs.

Output Format

Prefer this shape:

## Summary
- ...

## Major Changes
- ...

## Testing
- ...

If the diff is empty, say so directly.
