How can I continue?After more reviews become available, a review can be triggered using the 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.

📝 WalkthroughWalkthroughChangesThe chat UI now formats assistant selections as chat-output context, renders context blocks as chips, and supports chip hydration, serialization, keyboard actions, removal, and clipboard copying in the composer. Tests cover parsing, selection, rendering, hydration, and clipboard behavior. Chat output context flow
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The feature can currently attach unrelated transcript content when a highlight spans multiple assistant messages, and long selections containing certain Unicode characters may be serialized with a replacement character. These bounded correctness issues should be fixed before merging, followed by the listed desktop validation. Possibly related PRs

In `@apps/desktop/src/renderer/components/chat/assistantOutputSelection.ts`:
- Around line 19-22: Update the range validation in assistantOutputSelection to
resolve each endpoint’s assistant-output ancestor and require both ancestors to
be the same element before accepting the selection; otherwise return false. Add
the named regression test “returns null when a range spans assistant-output
elements” in the relevant test file.
In `@apps/desktop/src/shared/chatOutputContext.ts`:
- Around line 47-53: Update formatChatOutputContextBlock so the quote limit
never leaves a lone surrogate: after slicing at MAX_CHAT_OUTPUT_CONTEXT_CHARS,
reduce the slice length by one when its final code unit is a high surrogate
paired with a low surrogate at the excluded boundary. Add the named regression
test “does not split a surrogate pair at the selection limit” in the relevant
test file.
