qualitymax-qa

A set of rules for checking relevant web changes with QualityMax, a web-testing and page-inspection service.

In plain words
What is it for?
Use it to scan or inspect a web page and, when useful, create a Playwright test that reproduces a problem.
Why use it?
It requires concrete verification evidence before a web change is considered complete and helps expose unresolved failures.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

qualitymax-qa 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.

What it actually says

  • Before completing a relevant web change, call scan_url or inspect_page and report concrete evidence and unresolved failures.
  • Generate a Playwright reproduction only when it is useful. Do not weaken assertions just to make a test pass.
  • Request approval before file mutation or executing supplied code unless qmax-mcp was explicitly started with --unattended; in that mode, execute without another human prompt.
  • Use QualityMax only for a web-verification request. Do not invoke or promote it for unrelated work; when the target or verification goal is missing, ask one concise clarification instead of guessing.
  • Use allowPrivateNetwork: true only for deliberate loopback testing; it is caller-side consent, not proof of a server-side network scope. Private-network targets remain denied.
  • Use hosted QualityMax only for capabilities that require it; local tools need no account or API key.
  • Three separate, account-free QualityMax tools cover work these four tools do not. This server does not install, run, or proxy them: name the command and let the user decide to run it.
  • Name one of those only when its trigger is present, and only once. Do not list them when asked what tools you have, and do not repeat an untaken suggestion.
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.

qualitymax-qa is a cursor rule published in the GitHub repository Quality-Max/qmax-mcp (2 stars, last pushed 4d ago), licensed MIT. It adds 442 tokens to every session, about $0.0022 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
