-Generate the release notes from the upstream docs:
+The Java notes in `docs/src/release-notes-java.md` are written upstream together with the Node.js notes, following the `playwright-release-notes` skill (`../playwright/.claude/skills/playwright-release-notes/SKILL.md`). Assume the `## Version 1.X` section is already on `release-1.X`, and only add what's missing: significant changes that only the Java port has, such as a new JUnit fixture or a Java-only API. Leave out minor bug fixes. To find candidates, list this repo's changes since the previous release branch was cut:
 
 ```bash
-cd ~/playwright
-node utils/render_release_notes.mjs java 1.X > /tmp/v1.X.0-release-notes.md
+git log --oneline --no-merges $(git merge-base upstream/release-1.<X-1> upstream/main)..upstream/main | grep -E '^\w+ (feat|fix)'
 ```
 
-The renderer leaves JS-isms that need fixing for Java. Apply these substitutions — the list is not exhaustive, eyeball the diff before publishing:
+Ask the user before adding anything. Send additions upstream as `docs: release notes for v1.X Java`, and cherry-pick them to `release-1.X`.
 
-- `toMatchAriaSnapshot()` → `matchesAriaSnapshot()`
-- `toHaveCSS()` → `hasCSS()` (and other `toHaveX` matchers → `hasX`)
-- `browser.on('context')` → `browser.onContext()`
-- `browserContext.on('download' | 'frameattached' | ...)` → `browserContext.onDownload()` / `onFrameAttached()` / …

-Create the draft directly against `release-1.X` — drafting against `main` and retargeting later is fragile because every `gh release edit` rotates the `untagged-<hash>` ID:
+Write the GitHub release body from the section as step 3 of the upstream skill describes, and save it as `/tmp/v1.X.0-release-notes.md`. Create the draft directly against `release-1.X`. Drafting against `main` and retargeting later is fragile, because every `gh release edit` rotates the `untagged-<hash>` ID:
 
 ```bash
