/changelog

Generate a changelog entry for the current session in Batch Creative Studio.

Steps

1. Gather changes

   Run: git diff --stat HEAD~1..HEAD

   If no commits yet in this session, use: git diff --stat

2. Categorize changes

   Group files by type:

   • Added — new files
   • Modified — changed files
   • Deleted — removed files

   Then group by domain:

   • frontend: app/ (client UI), components/**, SSE client, visual language
   • backend: app/api/**, orchestrator, retry engine, rate limiter, SSE server stream, blob signing, state store, failover engine
   • providers: lib/providers/**, adapters, provider config, reference normalization
   • testing: **/*.test.ts, fixtures, fake provider
   • docs: docs/components/, docs/coverage.md
   • security-backend: docs/security/**, SECURITY.md

3. Write entry

   Format as a markdown changelog entry:

   ## [Session] <YYYY-MM-DD>
   
   ### Added
   - ...
   
   ### Changed
   - ...
   
   ### Fixed
   - ...
   

   Focus on the why, not the what. Describe the purpose of changes, not just file names.

4. Output

   Print the changelog entry to the terminal. Do not write to a file unless the user asks.
