Generate Changelog Entries
Generate concise changelog entries for each package with changes on the current branch compared to main, and insert them into the package CHANGELOG.md files.
Current Branch State
Changed files:
!git fetch origin main 2>/dev/null; git diff --name-only origin/main 2>/dev/null
Commit messages (check for Changelog-ignore directives):
!git log --pretty=format:'%B---' origin/main..HEAD 2>/dev/null
Diff for all packages:
!git diff origin/main -- packages/ 2>/dev/null
Package Detection
From the changed files above, determine which packages need entries:
- Files matching
packages/<name>/src/** mean <name> is changed — extract the second path component as the package name.
- If ANY file starts with
typescript/, treat ragbits-chat as a changed package.
- Ignore files outside
packages/*/src/ and typescript/ (docs, scripts, CI, etc.).
Changelog-Ignore
Check the full commit messages for lines matching Changelog-ignore: <package-name>. Skip any listed package entirely.
For Each Package
1. Read existing CHANGELOG.md
Read packages/<package>/CHANGELOG.md. Look at existing entries to understand the style used in this package.
2. Generate entry
Using the commit messages and the package diff above, write a changelog entry following these rules:
- Start with a category prefix:
feat:, fix:, refactor:, docs:, test:, chore:, etc.
- Single concise line describing the main user-facing change
- Focus on what changed for users, not internal implementation details
- If there are multiple significant changes, create one entry per distinct change
- Match the style of existing entries in the CHANGELOG
3. Insert into CHANGELOG.md
Edit packages/<package>/CHANGELOG.md — add entries after ## Unreleased as bullet points:
## Unreleased
- <new entry here>
Summary
After all packages are processed, report:
- Packages with generated entries (and what they are)
- Packages skipped due to Changelog-ignore
- Packages with no meaningful user-facing changes
