Deprecated Vitest config options are old settings that no longer work in Vitest 4.x. This Skill scans your vitest.config.* files to detect outdated keys in pool, coverage, workspace, browser mode, dependencies, and reporter configurations, then flags them for migration to current equivalents.

Vitest 4.x deprecated several config patterns across pool settings, coverage options, workspace structure, browser mode, reporter setup, and environment variables. This Skill reviews these areas and recommends modern replacements to align your configuration with Vitest 4.x best practices.

Yes. Beyond detecting deprecated patterns, this Skill audits your Vitest configuration against current best practices, identifies misconfigurations, and produces a remediation plan so you can update your setup to align with Vitest 4.x standards.

Yes. This Skill validates both single and workspace Vitest configurations, checking pool, coverage, browser mode, dependencies, and reporter settings across workspace projects to ensure consistent, non-deprecated patterns.

Ensure your Vitest configuration files (vitest.config.ts, vitest.config.js, or equivalent) are present and readable. Have your project structure documented so the Skill can validate workspace organization alongside deprecated option detection.

The Skill produces a concise remediation plan listing each deprecated key, its Vitest 4.x replacement, and required changes. Use this plan to update your vitest.config.* file manually or programmatically with the modern equivalents.
