commit-categories

name	commit-categories
description	Commit categorization rules for changelogs and "what's new" summaries. MUST be loaded before categorizing commits in changelog or whats-new commands. Provides the canonical path-based category table used to group commits by area.

Commit Categories

Categorize commits by the files they touch, using the primary area for commits spanning multiple categories.

Category	Path patterns
API	src/workerd/api/ (excluding node/ and pyodide/)
Node.js compat	src/workerd/api/node/, src/node/
Python	src/workerd/api/pyodide/, src/pyodide/
Rust	src/rust/
Cloudflare APIs	src/cloudflare/
I/O	src/workerd/io/
JSG	src/workerd/jsg/
Server	src/workerd/server/
Build	build/, MODULE.bazel, BUILD.bazel
Types	types/
Docs / Config	Documentation, agent/tool configs, .md files
Tests	Changes exclusively in test files
Other	Anything that doesn't fit above

Cross-cutting callouts

These are not primary categories — they are additional callout sections that appear alongside the main categories whenever a commit touches the relevant files. A single commit can appear in both a primary category and one or more callouts.

Callout	Trigger
New/Updated Compat Flags	Changes to src/workerd/io/compatibility-date.capnp or new compatibilityFlags references in code
New/Updated Autogates	Changes to src/workerd/io/supported-autogates.h or new autogate registrations

When either callout applies, add a dedicated section after the main categories listing each new or modified flag/gate with a brief description. These must never be buried inside a general category bullet — they are high-visibility items that reviewers and release-note readers need to spot immediately.

How to categorize

1. For each commit, run git diff-tree --no-commit-id --name-only -r <hash> to list files changed.
2. Match changed files against the path patterns above.
3. Assign the commit to whichever category covers the majority of its changes.
4. For commits touching multiple areas, list under the primary area (the one with the most changed files or the most significant change).
5. Check every commit against the cross-cutting callout triggers. If a commit adds or modifies compat flags or autogates, note it in the corresponding callout section in addition to its primary category.
6. Omit empty categories and unused callout sections from output.
