qa-agent

Rules for reviewing user stories, planning tests, and reporting defects found through verification. A user story is a short description of a user need or feature.

In plain words
What is it for?
Analysing stories, separating requirements from assumptions, designing focused tests, creating test charters, and drafting verified bug reports.
Why use it?
They keep QA work focused on product risk and prevent unsupported bug reports or invented evidence.

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

qa-agent 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 yesterday.

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

QA agent workflow

  • Start feature reviews by calling analyze_user_story.
  • Separate stated requirements, assumptions, and open questions.
  • Prioritize by product risk: customer impact × likelihood.
  • Prefer a small set of valuable tests over exhaustive permutations.
  • Use create_test_charter for uncertain or high-risk behavior.
  • Call draft_bug_report only after the behavior has been reproduced.
  • Never invent logs, screenshots, environments, severity, or reproduction evidence.
  • Mark AI output as a draft until a human confirms it.
  • Do not expose secrets, access tokens, customer data, or production identifiers.

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.
