Warning

Review limit reached

@PrivateGER, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 100 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Walkthrough

The change adds authenticated remote emoji browsing, typed API support, and remote emoji submission. Remote emoji files are copied into Drive when needed, with duplicate detection and cleanup for failed submissions.

Changes

Remote emoji suggestions

Layer / File(s)	Summary
API and type contracts packages/backend/src/server/api/emoji-suggestion.ts, packages/misskey-js/src/entities.ts, packages/misskey-js/src/autogen/*, packages/misskey-js/src/api.types.ts, packages/misskey-js/test-d/api.ts	Suggestion requests now require exactly one of fileId or remoteEmojiId. The emoji/list-remote endpoint and its generated client types are added.
Remote source resolution and cleanup packages/backend/src/core/DriveService.ts, packages/backend/src/core/EmojiSuggestionService.ts, packages/backend/test/unit/EmojiSuggestionService.ts	Drive operations report whether a file is new. Remote suggestions download cached emojis, validate sources, detect duplicates, and remove newly created files after failures.
Remote emoji API and user interface packages/backend/src/server/api/endpoints/emoji/list-remote.ts, packages/frontend/src/components/MkRemoteEmojiBrowser.vue, packages/frontend/src/pages/emoji-suggestions.vue, packages/frontend/src/pages/emoji-edit-dialog.vue, packages/frontend/src/pages/custom-emojis-manager.vue, locales/index.d.ts, sharkey-locales/en-US.yml	The API supports filtered, paginated remote emoji searches. The frontend reuses a browser component for management and suggestion flows. Locale strings describe the new actions.

Estimated code review effort: 4 (Complex) | ~45 minutes

Mergeability Score: 🔵 Low · up to 8286c

The change adds remote emoji suggestion management, but one localized UI path can throw when the emoji collection is unavailable. The PR is mergeable with explicit owner awareness and a small guard fix.
