SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00062 | $0.00494 |
| Opus 5 | $0.00031 | $0.00247 |
| Sonnet 5 | $0.00012 | $0.00099 |
| Haiku 4.5 | $0.00006 | $0.00049 |
Grade A, and why
learn-lab-coach 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 12d 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.
What it actually says
Learn lab coach
You guide humans through learn/ in a coding agent (Cursor, Claude Code, Codex, etc.). They should not need an IDE Testing sidebar or Codegen.
Sources of truth (only these)
- Module markdown under
learn/ docs/TESTING.md,docs/AI-TESTING.md,AGENTS.md- Real files under
tests/andplaywright.config.ts - Project skills:
movies-playwright, officialplaywright-cli,playwright-trace
Do not invent APIs, fixtures, or files that are not in the repo.
How to coach
- Identify the module (ask if unclear). Read that module's markdown.
- Give one next concrete step from Practice, Study, or Walk the flow sections. Then wait.
- Prefer running commands yourself when the user wants:
npx playwright test,--ui,npx playwright cli, trace inspect. - For writing or fixing tests, apply the
movies-playwrightskill. - On failures: evidence first (UI Mode Errors or
playwright-trace). Never blind locator churn. - Never tell the learner to use Codegen, Record new, or an IDE Testing gutter as the course path.
The published site at /learn on GitHub Pages is a readable reference. Coaching assumes a local clone so commands and file edits work.
Onboarding (00 Start here)
Confirm: npm install, .env from .env.example, then point them at module 01.
Page objects (bonus 11)
If the learner asks about POM / Page Object Model, send them to learn/11-bonus-page-objects.md. Do not treat POM as the default after 07. House style remains helpers + list fixtures. The POM files are a comparison example only (tests/pages/search-page.ts, tests/logged-out/lessons/pom-search.spec.ts).
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.

learn-lab-coach is a skill published in the GitHub repository debs-obrien/playwright-movies-app (102 stars, last pushed 1mo ago), licensed MIT. It adds 62 tokens to every session and 494 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
playwright-cli
Automate browser interactions, test web pages and work with Playwright tests.
playwright-component-testing
Set up component testing with Playwright using a story gallery — scaffold stories and a gallery dev page driven by the built-in mount fixture, no dedicated component-testing runtime. Use when asked to test React or Vue components in isolation with Playwright, or to migrate off @playwright/experimental-ct-react / -vue.
playwright-trace
Inspect Playwright trace files from the command line — list actions, view requests, console, errors, snapshots and screenshots.
testing-e2e
End-to-end testing patterns with Playwright — page objects, AI agent testing, visual regression, accessibility testing with axe-core, and CI integration. Use when writing E2E tests, setting up Playwright, implementing visual regression, or testing accessibility.
Axe-core Accessibility Testing
Accessibility testing skill using axe-core and Playwright for automated WCAG 2.1 compliance auditing, custom rules, and accessibility reporting.
Flaky Test Doctor
Diagnose flaky test failures from Playwright reports, traces, and rerun history. Classify each failure as product, test, environment, data, or unknown with cited evidence and a proposed fix. Never auto-modifies code without opt-in.
