Playwright Page Objects

What it does

When your agent uses it

• Creating page objects
• Refactoring Playwright E2E tests for better maintainability with Page Object Model patterns

Example prompts

• “/playwright-page-objects”

Requirements

• Pre-approved tools (allowed-tools): Bash, Read, Write, Edit

Workflow steps

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

1. 1Fixtures over PageManager — On-demand instantiation, automatic setup/teardown, native TypeScript inference
2. 2Composition over inheritance — Compose from focused components, avoid deep class hierarchies
3. 3Role-based selectors first — getByRole() > getByLabel() > getByText() > getByTestId()
4. 4Tests own assertions — Page objects expose state via getters, tests make assertions
5. 5Separate pages by workflow — ProductListPage ≠ ProductDetailsPage (different user interactions)
6. 6Readonly locators — All page object locator properties should be readonly
7. 7Fluent interfaces — Methods return this for chaining; navigation methods return target page object
8. 8Private internals — Mark implementation details (spinners, retry logic, helpers) as private
9. 9Wait for stability — Use waitForPageLoad(), waitForResponse() before assertions
10. 10High-level actions — Create AppActions class for complex multi-page user flows

What it can do on your machine

Read from SKILL.md and the folder at commit 6aa5c9c. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Bash
  • Read
  • Write
  • Edit

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md.

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

• Network

  No URLs in SKILL.md.

  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

Playwright Page Objects loads about 1k tokens when it runs, and up to ~8.2k if it reads all its reference files. Until then it costs about 38 tokens; SKILL.md has 297 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~38

When it runs · the whole SKILL.md, loaded when a task matches

~1k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~8.2k

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

  allowed-tools: Bash, Read, Write, Edit

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.

1. page.getByRole('button', { name: 'Add to Cart' })  // Preferred
2. page.getByLabel('Email')                           // Form inputs
3. page.getByText('Welcome back')                     // Non-interactive
4. page.getByPlaceholder('Search...')                 // When no label
5. page.getByTestId('cart-item-count')                // Escape hatch
