Skill erikfiala/e2e-tester/.cursor/skills/tester

Run end-to-end web quality audits with Playwright and Lighthouse using existing project scripts first. Use when the user says /tester, e2e test, smoke test, Playwright audit, Lighthouse audit, performance audit, accessibility audit, dark mode audit, mobile audit, or asks for 100/100 Lighthouse improvement guidance.From its SKILL.md

E2E Playwright + Lighthouse Tester

Use this skill to run reproducible e2e and Lighthouse checks across a target web repo, with discovery-first command selection and clear reporting.

Workflow

Discover first
- Run:
  - python3 .cursor/skills/tester/scripts/discover_audit_targets.py .
  - Optional JSON output: python3 .cursor/skills/tester/scripts/discover_audit_targets.py . --json
- Read discovered package scripts, runner files, and PWA signals before deciding what to run.
Runner selection priority
- Prefer existing npm / pnpm / yarn scripts that already run Playwright and Lighthouse.
- Otherwise use checked-in runner files in common locations (perf/, scripts/, e2e/, tests/).
- Only use ad-hoc npx playwright / npx lighthouse commands if no native runner exists.
Execution matrix
- For Lighthouse, target all slices when technically possible:
  - light-desktop
  - light-mobile
  - dark-desktop
  - dark-mobile
- Attempt categories:
  - performance
  - accessibility
  - best-practices
  - seo
  - pwa (when supported by installed Lighthouse and app signals)
- Prefer preview or production-like mode instead of noisy local dev mode when the repo supports it.
100/100 objective
- Always optimize toward 100/100 in Lighthouse categories and Web Vitals-related audits.
- Do not claim false success; explicitly list blockers and remaining deltas to 100.

Reporting contract

Always report by package/surface:

Commands run, including whether native or adapted.
Playwright findings: failing flows, flaky clues, console/page errors, failed requests, auth blockers.
Lighthouse findings per matrix slice (light-desktop, light-mobile, dark-desktop, dark-mobile).
A dedicated 100/100 gap analysis section with highest impact opportunities.
Explicit coverage gaps (skipped routes, no dark mode, no mobile emulation, missing credentials, unsupported PWA category).

Guardrails

Keep commands non-interactive whenever possible.
Never silently skip a matrix slice; report why it was skipped.
If the repository is not a web app, stop quickly and state that no web target was detected.
