Automated Release Notes

Pipe git log into contenox run and get grouped markdown release notes back. No custom chain, no setup — just shell composition.

CI pipeline

PREV_TAG=v0.9.0
git log --oneline "$PREV_TAG"..HEAD | \
  contenox run "Group these commits under ## Features, ## Bug Fixes, ## Improvements, ## Documentation. Omit empty sections. No preamble." \
  > RELEASE_NOTES.md

Output example:

## Bug Fixes
- Fix lockfile
- Fix naming drift

## Improvements
- Improve naming

## Documentation
- Update docs

The shell produces the commit list; contenox is just the formatter. No --shell flag is needed because contenox never runs the command itself — the model only sees the commit lines.

Tips

• Use a stronger model for better grouping. Override per-invocation:

  git log --oneline "$PREV_TAG"..HEAD | \
    contenox run --model gpt-4o --provider openai \
    "Group these commits under ## Features, ## Bug Fixes, ## Improvements, ## Documentation. Omit empty sections. No preamble." \
    > RELEASE_NOTES.md
  

• Point at a specific tag: set PREV_TAG to whichever tag covers the range you want. For the very first release, use the root commit hash instead of a tag.
• Filter merge commits: add --no-merges to the git log command before piping.
• Upload to GitHub:

  gh release create v0.9.1 --notes-file RELEASE_NOTES.md
