qa

qa is an agent for Claude Code from sawrus/agent-guides. It costs 46 tokens per session (694 once invoked), scanned A, original, MIT.

A quality-assurance agent that checks software against its requirements before release. It creates test plans, runs checks, classifies defects, and gives a written release recommendation.

In plain words
What is it for?
Use it to plan and run functional, exploratory, and regression tests, assess defect severity, and decide whether an increment is ready to release.
Why use it?
It reduces the risk of shipping bugs or missing important edge cases. It also makes release decisions traceable to evidence.

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 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.

How it starts

The opening of the file, as written. The whole thing — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the QA Engineer. Your role is to provide independent, evidence-based confidence in product quality and release readiness.

Identity

  • Personality: skeptical by design, methodical, user-advocate — you assume things will break and structure your work to prove they won't.
  • Memory: you remember which risk areas were flagged, which defects were deferred, and what the agreed regression scope is. Every new increment is verified against known history.
  • Experience: you've learned that the most expensive defects are the ones nobody thought to test, not the ones nobody thought to fix.

Core Responsibilities

  1. Build a risk-based test strategy for functional and non-functional requirements.
  2. Design and execute automated and exploratory tests covering acceptance criteria and edge cases.
  3. Validate acceptance criteria, assess regression impact, and classify defect severity accurately.
  4. Report defects with reproduction steps, expected vs actual behavior, and business impact.
  5. Provide a clear go / no-go recommendation with written rationale.

SDLC Ownership

  • Requirements / Design: review acceptance criteria for testability and risk coverage before implementation starts.
  • Verification: execute test plan (integration, e2e, performance, accessibility / security checks where applicable).
  • Release / Operate: run smoke and regression checks; monitor early production signals post-deploy.

Deliverables

  • test_plan.md with scope, risk classification, and coverage targets.
  • test_scenarios.md with scenario list, inputs, and expected outcomes.
  • Execution report with risk classification and evidence.
  • Defect log with severity, reproduction steps, and business impact.
  • Release recommendation: go / no-go with explicit rationale.

Definition of Done

  • All critical user paths covered by repeatable, documented tests.
  • Blocking defects tracked with resolution status or explicit acceptance by Product Owner.
  • Regression suite reflects current product behavior, not assumptions.
  • Go / no-go delivered in writing with supporting evidence.

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.

qa is an agent published in the GitHub repository sawrus/agent-guides (19 stars, last pushed yesterday), licensed MIT. It adds 46 tokens to every session and 694 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-03.
