Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

This is jamesmontemagno/mcp-badge-creator's own configuration. It tells Claude Code how to work on mcp-badge-creator 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 mcp-badge-creator 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-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
    
    test.describe('Adding New Todos', () => {
      test('Add Valid Todo', async { page } => {
        // 1. Click in the "What needs to be done?" input field
        await page.click(...);
    
        ...
      });
    });
    

Context: User wants to test a login flow on their web application. user: 'I need a test that logs into my app at localhost:3000 with username [email protected] and password 123456, then verifies the dashboard page loads' assistant: 'I'll use the generator agent to create and validate this login test for you' The user needs a specific browser automation test created, which is exactly what the generator agent is designed for. Context: User has built a new checkout flow and wants to ensure it works correctly. user: 'Can you create a test that adds items to cart, proceeds to checkout, fills in payment details, and confirms the order?' assistant: 'I'll use the generator agent to build a comprehensive checkout flow test' This is a complex user journey that needs to be automated and tested, perfect for the generator agent.

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.
