What it does

Learn Lab Coach is an agent skill from debs-obrien/playwright-movies-app. Coach a learner through the learn/ Playwright Movies curriculum. Use when the user names a module (e.g. 07), says learn/, course, or asks for the next step. Agent-first: CLI, UI Mode, traces. Not IDE Testing UI or Codegen.

Its SKILL.md is about 490 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering Browser testing and Project scaffolding. It works with Playwright. The repository describes itself as: Playwright tests for a Movie App. The licence is MIT.

When your agent uses it

  • The user names a module (e.g
  • Tasks that involve Browser testing
  • Tasks that involve Project scaffolding

Example prompts

  • “/learn-lab-coach”

Requirements

  • Node.js

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Identify the module (ask if unclear). Read that module's markdown.
  2. Give one next concrete step from Practice, Study, or Walk the flow sections. Then wait.
  3. Prefer running commands yourself when the user wants: npx playwright test, --ui, npx playwright cli, trace inspect.
  4. For writing or fixing tests, apply the movies-playwright skill.
  5. On failures: evidence first (UI Mode Errors or playwright-trace). Never blind locator churn.
  6. Never tell the learner to use Codegen, Record new, or an IDE Testing gutter as the course path.

What it can do on your machine

Read from SKILL.md and the folder at commit e628ea9. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npx
    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx and npm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Learn Lab Coach loads about 487 tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 236 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~60
When it runs · the whole SKILL.md, loaded when a task matches
~487

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:35
    Confirm: `npm install`, `.env` from `.env.example`, then point them at module 01.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Coach a learner through the learn/ Playwright Movies curriculum. Use when the user names a module (e.g. 07), says learn/, course, or asks for the next step. Agent-first: CLI, UI Mode, traces. Not IDE Testing UI or Codegen.

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/ and playwright.config.ts
  • Project skills: movies-playwright, official playwright-cli, playwright-trace

Do not invent APIs, fixtures, or files that are not in the repo.

How to coach

  1. Identify the module (ask if unclear). Read that module's markdown.
  2. Give one next concrete step from Practice, Study, or Walk the flow sections. Then wait.
  3. Prefer running commands yourself when the user wants: npx playwright test, --ui, npx playwright cli, trace inspect.
  4. For writing or fixing tests, apply the movies-playwright skill.
  5. On failures: evidence first (UI Mode Errors or playwright-trace). Never blind locator churn.
  6. 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).
