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.

Code Review
This pull request adds a new test suite for the handleRateLimit function, covering scenarios with valid, missing, and invalid rate limit reset headers. The feedback highlights a test anti-pattern used in all three test cases, where expect.fail() is placed inside a try block and its resulting error is caught by the catch block, masking the assertion failure. It is recommended to capture the thrown error in a local variable and perform assertions outside of the try/catch block to ensure clear and debuggable test failures.

Using expect.fail() inside a try block where the catch block catches all errors is a test anti-pattern. If handleRateLimit(res) does not throw, expect.fail() will throw an AssertionError, which is then caught by the catch block. The assertion expect(e).toBeInstanceOf(RateLimitError) will then fail, masking the original expect.fail() message and making debugging confusing.
A cleaner and safer pattern is to catch the error into a local variable and perform assertions on it outside the try/catch block.
let error: unknown;
try {
handleRateLimit(res);
} catch (e) {
error = e;
}
expect(error).toBeInstanceOf(RateLimitError);
