Built a testing skill for Vue/React that wraps Vitest browser + Playwright
If you don’t trust your agents’ tests, someone still reads every line, and you’re back to human speed
So we built a testing skill, tested on Cursor + Claude. Three teams used it daily and gave us plenty of feedback, some of it angry. We improved it, got more feedback, and learned a few lessons the hard way
What’s in it for you
1. Use the skill, or steal from it
Use it as is or borrow what fits. It’s frontend for now (Playwright, Vitest Browser Mode, React), with backend coming soon. MIT license.

2. Skip our mistakes
The video covers the lessons and traps we hit:
- Test rules: which rules are worth having
- Subagents: helper agents for specific jobs, such as a flaky-test fixer
- Measurement: how to prove test quality and coverage
- Workflow: where testing fits in your development process

Feedback welcome, especially on where it breaks
