playwright-ai-pom-starter: Instructions file for Codex

AGENTS.md

playwright-ai-pom-starter AGENTS.md is an instructions file for Codex, OpenCode from alexhvastovich/playwright-ai-pom-starter. It costs 451 tokens per session, scanned A, original, MIT.

Repository instructions for writing maintainable browser tests with Playwright, a tool for testing websites in a real browser. They define how to organize page objects, locators, fixtures, assertions, and test identifiers.

In plain words
What is it for?
Use them when adding or renaming Playwright test scenarios. They guide how to find buttons and fields, share page objects, and check user-visible behavior.
Why use it?
They reduce fragile tests caused by selectors tied to a page's current HTML structure. They also keep test files consistent and easier to reuse.

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

playwright-ai-pom-starter AGENTS.md 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 11d 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

Repository instructions

This is a teaching repository for maintainable Playwright tests. Keep examples small, public-safe, and runnable against https://alexusadays.com.

Architecture

  • Put selectors and browser actions in pages/.
  • Access page objects through PomManager via fixtures/pom.fixture.ts.
  • Keep assertions about page behavior in page objects when they describe a reusable page contract; keep scenario outcomes in tests.
  • Never instantiate page objects directly in a test.

Locator contract

Use the most user-facing stable locator available:

  1. getByRole with an accessible name.
  2. getByLabel for labelled form fields.
  3. getByTestId for explicit automation contracts or ambiguous controls.

Do not use XPath, CSS classes, nth-child, or long text selectors. A locator must explain what the element means, not how the current DOM happens to look.

Test rules

  • Import test and expect from fixtures/pom.fixture.
  • Apply skills/name-playwright-test/SKILL.md to every new or renamed scenario.
  • Keep the same stable test case ID in the spec, file name, and test title.
  • Add every Page Object to pages/ManagePage.ts as a lazy getter.
  • Use web-first assertions.
  • Never use waitForTimeout.
  • Keep tests independent and safe to run in parallel.
  • Do not add secrets, real customer data, or private URLs.
  • Run npm test before committing.
  • Follow docs/FIXME.md; never use test.fixme() solely to make the gate pass.

AI workflow

For a new flow, write or update a short specification in specs/, then use the skills/add-playwright-test skill. Treat AI output as a draft that must pass the same architecture and validation gates as human code.

The official Playwright planner, generator, and healer definitions are in .codex/agents/. Use seeds/login.seed.spec.ts through the agent-seed project as their environment seed. Generated test code must still follow this file's POM and locator contracts.

Changes

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.
