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.

| Layer / File(s) | Summary |
|---|---|
Rule contract and matcher schemas/WebpackOptions.json, lib/rules/RuleSetCompiler.js, lib/NormalModuleFactory.js, test/Validation.test.js, AGENTS.md |
The schema and effect data define descriptionRelativePath. The rule compiler registers the matcher. Validation data and update guidance include the new property. |
Resource path evaluation lib/NormalModuleFactory.js |
Normal resources pass their resolved relative path to rule evaluation. Match-resource requests pass undefined. |
Configuration coverage and release metadata test/configCases/rule-set/description-relative-path/*, .changeset/012-rule-set-description-relative-path.md |
The configuration case tests string, regular expression, function, negated, nested-path, match-resource, and package-resolution behavior. The changeset records a minor release. |

Regenerate the public schema artifacts.
This cohort adds the schema property but does not include regenerated declarations. Without the generated types.d.ts, TypeScript configurations reject descriptionRelativePath although the schema accepts it. Run yarn fix:special and commit its generated artifacts.
As per path instructions, “Schema edits must be followed by yarn fix:special regeneration in the same PR.”

Sources: Coding guidelines, Path instructions
Matches a module by its path relative to the root of the package it belongs to, which is stable across hoisting, pnpm store layouts and symlinked workspace packages, unlike a regexp over the absolute resource path.
…urce The previous assertion also passed when the value leaked, because the rule it relied on was already blocked by its `descriptionData` condition.
A new `module.rules` property changes the "these properties are valid" message, whose inline snapshot only the integration matrix runs. Note it in AGENTS.md next to the other snapshots a schema property leaks into.

Summary
Closes #18562.
module.rulescan select a package withdescriptionData, but not a module inside it: the only alternative is a regexp over the absolute resource path, which over-matches (a/lib/button\.js$/tail also hitsvendor/lib/button.js) and cannot be written at all for pnpm store layouts or symlinked workspace packages, where the package root is not a segment of the resource path.descriptionRelativePathmatches the resolver's package-root-relative path (./lib/button.js, always forward slashes). Being part of the effect data, it is also handed torule.usefunctions, which covers the dynamic-dispatch half of the issue.Supersedes #19031, which exposed the value only as a second argument to function conditions — no string/regexp/
notform, no schema or type surface.What kind of change does this PR introduce?
feat
Did you add tests for your changes?
Yes —
test/configCases/rule-set/description-relative-path, covering the string, regexp, function andnotcondition forms, access from arule.usefunction, the match-resource case (value unset, as fordescriptionData), and that matching is anchored at the package root.Does this PR introduce a breaking change?
No.
If relevant, what needs to be documented once your changes are merged or what have you already documented?
The
descriptionRelativePathcondition in themodule.rulesdocs: it is relative to the nearest description file (usuallypackage.json), so a nestedpackage.jsonmoves the anchor, and it is unset when no description file is in scope or a match resource is used.Use of AI
Yes — Claude Code was used to verify which parts of #18562 already work on
main, to write the implementation and the test case, and to run the suites and lint. The API shape was decided and reviewed by me: a schema-level condition rather than an extra argument to function conditions, and the namedescriptionRelativePathfor consistency withdescriptionData.Generated by Claude Code
