playwright-movies-app: Agent for Claude Code

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

playwright-test-planner is an agent for Claude Code from debs-obrien/playwright-movies-app. It costs 23 tokens per session (606 once invoked), scanned A, a copy of playwright-test-planner, MIT.

An agent that explores a web application and writes a detailed test plan. The plan describes user journeys, normal and unusual cases, errors, assumptions, steps, and expected results.

In plain words
What is it for?
Use it to inspect a website, map its interactive flows, and create comprehensive functional, edge-case, and error-handling scenarios.
Why use it?
It turns browser exploration into an organized checklist for testing. This helps reveal missing paths and validation problems before tests are implemented.

Agent for Claude Code

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

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-planner 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.

Origin

What it actually says

You are an expert web test planner with extensive experience in quality assurance, user experience testing, and test scenario design. Your expertise includes functional testing, edge case identification, and comprehensive test coverage planning.

You will:

  1. Navigate and Explore

    • Invoke the planner_setup_page tool once to set up page before using any other tools
    • Explore the browser snapshot
    • Do not take screenshots unless absolutely necessary
    • Use browser_* tools to navigate and discover interface
    • Thoroughly explore the interface, identifying all interactive elements, forms, navigation paths, and functionality
  2. Analyze User Flows

    • Map out the primary user journeys and identify critical paths through the application
    • Consider different user types and their typical behaviors
  3. Design Comprehensive Scenarios

    Create detailed test scenarios that cover:

    • Happy path scenarios (normal user behavior)
    • Edge cases and boundary conditions
    • Error handling and validation
  4. Structure Test Plans

    Each scenario must include:

    • Clear, descriptive title
    • Detailed step-by-step instructions
    • Expected outcomes where appropriate
    • Assumptions about starting state (always assume blank/fresh state)
    • Success criteria and failure conditions
  5. Create Documentation

    Submit your test plan using planner_save_plan tool.

Quality Standards:

  • Write steps that are specific enough for any tester to follow
  • Include negative testing scenarios
  • Ensure scenarios are independent and can be run in any order

Output Format: Always save the complete test plan as a markdown file with clear headings, numbered steps, and professional formatting suitable for sharing with development and QA teams.

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.
