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.

📝 WalkthroughWalkthroughCodex native tool calls now execute through Octopal’s router, submit structured results to the app server, handle cancellation, and report terminal status. The router records results with at-most-once semantics and recovers from transport failures without replaying completed tools. ChangesCodex tool execution
Estimated code review effort: 4 (Complex) | ~60 minutes Mergeability Score: 🟡 Moderate · up to When a tool execution fails during error recovery, the request can abort before recording a corresponding tool message, leaving conversation state incomplete and preventing the turn from continuing. This is a concrete merge-readiness correctness issue that should be fixed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

item_statusdoes not change provider behavior.
_collect_turnignoresitem/completednotifications, so theitem_statusparameter only varies unused payload data. The test therefore does not cover failed item status. Either drop the parameter or assert the behavior that depends on it.🤖 Prompt for AI Agents

⚠️ Unverified finding
Sandbox verification was unavailable.Confirm that wrapped providers still resolve
provider_id.
_ProviderWithCallDefaults(Line 401) does not exposeprovider_id, sogetattr(provider, "provider_id", "")returns""for a wrapped Codex provider. In that case the bridge isNoneand_handle_tool_call_at_most_oncealso skips the ledger branch, so native tool execution and at-most-once protection are both disabled. Verify whether any route passes a wrapped provider into_complete_route_with_tools. If it does, forwardprovider_idon the wrapper.

_FakeCodexClient.instancesis reset between tests.
instancesis a class attribute on_FakeCodexClient, and the subclasses inherit the same list. This test relies oninstances.index(self) == 0for its first client, and other tests indexinstances[0]. If no autouse fixture clears the list, leftover instances from earlier tests change the index and the tool request is never issued.

with return_exceptions enabled so one failed task does not abort recovery, then
continue appending available results. In execute, record an

Summary
Root cause
The provider previously interrupted an active turn before returning a synthetic failed tool response. Interruption is a cancellation operation, so the pending request could be discarded before the real tool result was available.
