Warning

Review limit reached

@youyongsong, we couldn't start this review because you've reached your PR review rate limit.

More reviews will be available in 41 minutes and 26 seconds. Learn how PR review limits work.

Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file).

⌛ How to resolve this issue?

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 credits.

🚦 How do rate limits work?

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

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, the refill rate gradually slows as usage increases. The highest same-day bursts are limited more strictly.

Please see our Fair Usage Limits Policy for further information.

Walkthrough

Adds a new doom-lint:no-legacy-os-names remark-lint rule to @alauda/doom that detects legacy OS name variants (MicroOS, KubeOS, micros, etc.) in Markdown nodes and MDX JSX attributes. The rule is re-exported from the lint index and registered in remarkrc.ts. A test suite and a patch changeset entry are included. The vendor directory is excluded from Prettier, ESLint, and TypeScript.

Changes

no-legacy-os-names lint rule

Layer / File(s)	Summary
Core lint rule: regex, helpers, and AST traversals packages/doom/src/remark-lint/no-legacy-os-names.ts	Defines LEGACY_OS_NAME_REGEX (Unicode-aware, matching micro os/micros/kube os variants) and AST helper types (StringValueNode, isStringValueNode). Implements two visitParents traversals: one scans string-valued nodes, another scans MDX JSX element attributes. Both extract and report legacy OS name matches via vfile.message with position and ancestors.
Rule export and remarkrc registration packages/doom/src/remark-lint/index.ts, packages/doom/src/remarkrc.ts	Re-exports noLegacyOSNames from the remark-lint index and adds it to the plugins array in the remark configuration (after noDeepList).
Tests, changeset, and vendor tooling config packages/doom/test/remark-lint/no-legacy-os-names.spec.ts, .changeset/add-legacy-os-name-lint.md, .prettierignore, eslint.config.js, tsconfig.json	Adds a test suite with four async test cases covering allowed names, legacy variants in markdown, detection in frontmatter/code blocks, and MDX JSX string attributes. Adds a patch changeset entry. Excludes vendor directory from Prettier, ESLint top-level ignores, and TypeScript exclude.

Poem

🐇 Hop hop, no more old OS names in sight,
A regex patrol checks each node just right.
MicroOS, KubeOS — banished with care,
The AST walks find them everywhere.
✨ Clean docs ahead, the warren agrees!
