feat(oxlint-config): report any flowing into typed code - #267
Turns on the five typescript/no-unsafe-* rules in library(). no-explicit-any only rejects a written any; these reject one that arrives from JSON.parse, toJS(), untyped libraries or an unresolved import and then flows into typed code.
Scope
Exported as unsafeAnyRules, so a consumer can turn them off per directory while adopting them. The README has the pattern.
Test files allow passing and storing any (asymmetric matchers such as expect.stringContaining() are typed any). Calls, member access and returns are still reported there.
JavaScript files are exempt: there is no annotation to turn an any into unknown, only a disable comment.
Both exemptions are exported as unsafeAnyOverrides, not added to libraryOverrides, so configs that spread libraryOverrides over another preset that already enables these rules keep its scope.
In this repo, plugin visitor code (untyped AST nodes) and both fixture folders keep them off.
Fixes in this repo. Mostly two narrowing leaks: Array.isArray narrows unknown to any[], and typeof x === "function" narrows to Function, whose calls return any. Local guards keep those values unknown. Parsed JSON and YAML now get an explicit unknown annotation. check-lockfile-workspace-versions.ts now checks that the parsed file is an object before returning it as a record.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The PR adds five unsafe-any rules to the library configuration and defines test-file and JavaScript-file overrides. It also updates source and test code to narrow unknown values, and adds shape validation for parsed lockfile data.
Changes: Unsafe-any rules and type-safety updates
Layer / File(s)
Summary
Rule configuration and exceptions packages/oxlint-config/src/index.ts, oxlint.config.ts, packages/oxlint-config/src/library-overrides.test.ts, packages/oxlint-config/README.md, .changeset/unsafe-any-rules.md
The library configuration exports and enables five unsafe-any rules. Test overrides disable unsafe-argument and unsafe-assignment checks; JavaScript overrides disable all five. Repository overrides, tests, documentation, and the changeset cover the rules.
stella/tooling#265: It changes repository overrides and library rule entries for the same five unsafe-any rules.
Merge Risk: Low · up to 70a6c
The configuration is mergeable with a small test correction or follow-up: individual unintended unsafe-any exemptions could escape detection, but no current runtime failure is established.

Explanation
The title names the main change: the five typescript/no-unsafe-* rules are enabled in library(), so any values that flow into typed code get reported. It uses the conventional feat(scope) prefix and is short and specific. The changeset adds these rules to the library preset, exports unsafeAnyRules and unsafeAnyOverrides, and includes the supporting fixes.
Full details: Description check
Explanation
The description states what the change does: it turns on the five typescript/no-unsafe-* rules in library(), explains the test-file and JavaScript-file exemptions, and lists the exports. It also covers the narrowing-leak fixes, the explicit unknown annotations for parsed JSON and YAML, the object check in check-lockfile-workspace-versions.ts, and the major-bump impact. This matches the changeset closely.
Full details: Docstring Coverage
Explanation
No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2.

If libraryOverrides contains only typescript/no-unsafe-return, this assertion still passes. It rejects the overrides only when they contain all five keys. Check each key separately to detect an unintended relaxation.
