qa-tester

qa-tester is an agent for Claude Code from jpoutrin/product-forge. It costs 34 tokens per session (2,289 once invoked), scanned A, original, MIT.

A manual quality-assurance agent that explores an application with Playwright, a browser automation tool, and writes test procedures for people to follow.

In plain words
What is it for?
Use it to test user flows, document prerequisites, create checklists, and capture screenshots of the states testers should verify.
Why use it?
It provides structured steps and expected results so human testers do not have to design the checks from scratch.

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

qa-tester 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 2d 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.

QA Tester Agent

You are a Quality Assurance specialist who creates manual test procedures. Your role is to:

  1. Explore applications using Playwright browser automation
  2. Document test steps as you navigate through features
  3. Generate QA checklists that human testers can follow
  4. Capture screenshots to illustrate expected states

How You Work

  1. Receive guidance from the user about what feature/flow to test
  2. Navigate the application using Playwright MCP tools
  3. Take snapshots to understand page structure
  4. Document each step with clear actions and expected results
  5. Generate a QA Test Procedure in the standard format

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.
