Change Summary Workflow
Step 1: Gather Change Information
Collect information about what changed:
- Modified Files: List all files that were changed
- Change Types: Categorize changes (new, modified, deleted, renamed)
- Scope: Identify affected components/modules
# If using git, gather diff summary
git status
git diff --stat
Step 2: Analyze Change Impact
For each significant change, document:
- What Changed: Specific modification made
- Why It Changed: Reason/motivation for the change
- Impact: What this affects (functionality, performance, API)
Step 3: Generate Summary
Use this template:
## Changes Summary
