Validate
Debug Rstack ecosystem CI failures for Rspack, Rsbuild, Rslib, Rspress, Rstest, and Rsdoctor, then attribute the real source PR or downstream change. Always use this skill when the user mentions Rstack eco-ci, rstack-ecosystem-ci, a suite turning red, a downstream regression, a green-to-red pivot, canary bisect, or daily eco-ci triage — even if they only ask "why is this suite failing", "which PR broke it", or "is this upstream project's fault". Use it to avoid over-blaming the first upstream commit that appears red in status data.
Benchmark and iteratively improve agent skills with Codex CLI or Claude Code by generating eval cases, comparing skill-guided vs baseline runs, grading outcomes, and recording actionable reports under skills-test/{skill-name}.
Migrate Jest or Vitest projects to Rstest. Use when asked to move from Jest/Vitest to Rstest, replace `jest`/`vi` APIs with `@rstest/core`, translate config into `rstest.config.ts`, update scripts/coverage/setup/mocks/snapshots/projects, or diagnose config-loading warnings, migration failures, and memory/performance regressions caused by Rstest's Rsbuild/Rspack execution model, DOM dependency bundling, runtime-mocked module build graphs, or version skew.
