testing-and-quality

testing-and-quality is a skill for Claude Code from martian56/claude-engineer. It costs 58 tokens per session (666 once invoked), scanned A, original, MIT.

A software quality checklist covering automated tests, browser checks, accessibility, and code quality. WCAG AA is a widely used accessibility standard for making websites usable by people with disabilities.

In plain words
What is it for?
Use it to run coverage checks, Playwright browser tests, accessibility tests, TypeScript and Python checks, linting, and formatting checks.
Why use it?
It prevents a project from being called finished without fresh evidence that its tests, key browser flows, accessibility checks, types, formatting, and linting pass.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

testing-and-quality scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Testing & Quality

Announce at start: "I'm using claude-engineer:testing-and-quality to enforce the four quality gates."

Iron Law

No "done" without all four gates passing, verified by fresh evidence. (Pairs with superpowers:verification-before-completion - assertions follow evidence, never precede it.)

The four gates (exact pass/fail commands; exit 0 = pass)

  1. Tests + coverage - FE vitest run --coverage; BE pytest --cov=app --cov-fail-under=80.
  2. E2E + zero console errors - playwright test (specs include a console-error/pageerror fixture and assert no 4xx/5xx on key routes). Drive flows and confirm every button/screen works via the Playwright + Chrome DevTools MCPs.
  3. Accessibility (WCAG AA) - playwright test a11y/ using @axe-core/playwright with tags wcag2a,wcag2aa,wcag21aa,wcag22aa; assert zero violations. Manual keyboard/focus spot-checks too.
  4. Strict types + lint clean - tsc --noEmit && eslint . && prettier --check . && ruff check . && ruff format --check . && mypy app.

The gate runner + commit gate

  • Scaffold scripts/quality-gate.mjs from templates/quality-gate.mjs. It runs all four gates and writes .claude-engineer/quality-gate-status.json ({ allPass, results }).
  • The claude-engineer PreToolUse(Bash) hook blocks git commit unless that file shows allPass: true. So: run node scripts/quality-gate.mjs → fix failures → commit. Intentional bypass: git commit --no-verify.
  • The same four commands are the finish condition and the CI merge condition (claude-engineer:ci-cd-pipeline).

Browser verification (MCPs - BYO install)

  • Chrome DevTools MCP - capture/assert zero console errors per screen, Lighthouse audits, network-failure checks.
  • Playwright MCP - drive real flows; confirm interactions actually work. Install per templates/recommended-mcps.md.

Full detail (test pyramid, coverage targets, Playwright setup, the console-error fixture, axe usage, exact commands): read references/testing-and-gates.md on demand.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
