@copilot

1. run pnpm install

2. fix the lint error

3. use the rstack-skill-evaluator skill to bench the rslib-best-practices skill

Addressed in 002cf4b (follow-up to b233bb5). I ran pnpm install, fixed the lint failure by making the tracked benchmark report spell-check clean, refreshed the linked skill digest in skills-lock.yaml, and added skills-test/rslib-best-practices/evals/evals.json so rslib-best-practices now has evaluator inputs to benchmark against. Validation is green (pnpm lint + final review/security checks).

@SoonIter I've opened a new pull request, #50, to work on those changes. Once the pull request is ready, I'll request review from you.

is the reason fixtures aren't tracked in the repository to prevent fixture rot?

by the way, need this feature to track the eval report of Rstest skill, merge merge merge.

fixture 理论上维护在 rstack-examples 仓库会降低维护成本，放在 skills 仓库的话会让这个仓库变得很大，skill 下载速度变慢

Theoretically, maintaining the fixture in the rstack-examples repository would reduce maintenance costs, while placing it in the skills repository would make that repository very large, slowing down the download speed of skills.

shouldn't it be rspack-examples, especially since we're dealing with many migration cases? but we can indeed maintain it in another repository and directly execute git clone during evaluation to completely isolate it.

@copilot rebase to the latest origin/main

Addressed in 4af0a5a. This branch is now rebased on the latest origin/main, so the merged skills-package-manager setup stays in main and this PR only carries the remaining evaluator-specific changes on top. No UI changes.

@copilot rebase to the latest origin/main

Done in 4af0a5a. The branch is rebased onto the latest origin/main and validated again after the update. No UI changes.
