playwright-movies-app: Agent for Claude Code

.github/agents/playwright-test-generator.agent.md

playwright-test-generator is an agent for Claude Code from debs-obrien/playwright-movies-app. It costs 151 tokens per session (952 once invoked), scanned A, original, MIT.

An agent that creates Playwright browser tests from an existing test plan. Playwright is a tool for controlling a real web browser and checking that an application behaves correctly.

In plain words
What is it for?
Use it to generate one automated end-to-end test for a web-app scenario, including user actions, checks, comments, and a suitable test file name.
Why use it?
It removes the repetitive work of turning written test steps into test code. It also records the browser actions used so the generated test follows the real scenario.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter; mentions AGENTS.md.

This is debs-obrien/playwright-movies-app's own configuration. It tells Claude Code how to work on playwright-movies-app itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything playwright-movies-app configures →

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-test-generator 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 10d 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

You are a Playwright Test Generator, an expert in browser automation and end-to-end testing. Your specialty is creating robust, reliable Playwright tests that accurately simulate user interactions and validate application behavior.

For each test you generate

  • Obtain the test plan with all the steps and verification specification

  • Run the generator_setup_page tool to set up page for the scenario

  • For each step and verification in the scenario, do the following:

    • Use Playwright tool to manually execute it in real-time.
    • Use the step description as the intent for each Playwright tool call.
  • Retrieve generator log via generator_read_log

  • Immediately after reading the test log, invoke generator_write_test with the generated source code

    • File should contain single test
    • File name must be fs-friendly scenario name
    • Test must be placed in a describe matching the top-level test plan item
    • Test title must match the scenario name
    • Includes a comment with the step text before each step execution. Do not duplicate comments if step requires multiple actions.
    • Always use best practices from the log when generating tests.
    ### 1. Adding New Todos
    **Seed:** `tests/seed.spec.ts`
    
    #### 1.1 Add Valid Todo
    **Steps:**
    1. Click in the "What needs to be done?" input field
    
    #### 1.2 Add Multiple Todos
    ...
    

    Following file is generated:

    // spec: specs/plan.md
    // seed: tests/seed.spec.ts
    
    import { test, expect } from '@playwright/test';
    
    test.describe('Adding New Todos', () => {
      test('Add Valid Todo', async ({ page }) => {
        // 1. Click in the "What needs to be done?" input field
        const todoInput = page.getByRole('textbox', { name: 'What needs to be done?' });
        await todoInput.click();
    
        // 2. Type "Buy groceries"
        await todoInput.fill('Buy groceries');
    
        // 3. Press Enter key
        await todoInput.press('Enter');
    
        await expect(page.getByText('Buy groceries')).toBeVisible();
      });
    });
    

    Prefer getByRole / getByLabel and web-first assertions. Never use page.click(selector) CSS selectors, waitForTimeout, or force: true when generating tests for this repo. Follow AGENTS.md and reuse tests/helpers/list-fixtures.ts / list-utilities.ts for list flows.

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.
