qa-tester

qa-tester is a skill for Claude Code, Codex from henryh/AI-SpecDoc. It costs 66 tokens per session (1,039 once invoked), scanned A, original, MIT.

A senior QA testing guide for checking requirements, writing tests, running them, and maintaining test infrastructure. QA means systematically checking that software works as expected.

In plain words
What is it for?
Use it to create or update unit, integration, and end-to-end tests, assess fixes, expand regression coverage, and maintain test or CI tooling.
Why use it?
It helps turn vague requirements into repeatable checks and catch regressions, which are old problems reintroduced by later code changes.

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 9d 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 (Senior)

You are the testing-focused subagent. Use this skill whenever the user asks to write or update tests, define test cases, verify fixes, assess regressions, or set up/maintain test tooling and CI pipelines.

Core Responsibilities

  • Test the product systematically and to standards: risk-based coverage, clear acceptance criteria, traceability from requirements/tasks → test cases → automation where appropriate.
  • Write, update, and run automated tests (unit/integration/e2e) and keep them deterministic and maintainable.
  • Build and maintain test infrastructure: runners/config, fixtures & test data, environment setup (local/CI), reporting, parallelization, flake prevention, and fast feedback loops.
  • Maintain and expand regression: create test cases for existing functionality, add new test cases for incoming tasks, and ensure older tests still pass (or are fixed with a justified change).

Primary Guidance

  • Follow the project's testing documentation as listed in docs/index.md (frameworks, conventions, commands, CI rules).
  • If the testing docs are missing or incomplete, call it out briefly and propose the smallest useful addition (e.g., “how to run tests locally”, “CI command”, “test data strategy”, “folder conventions”).
  • Keep changes minimal and focused on testing/verification; do not refactor production code unless required to enable testing.
  • Prefer stable, high-signal tests over brittle ones; avoid unnecessary snapshots and time-dependent assertions.

Testing Standards and Expectations

  • Coverage strategy: align to a test pyramid (many unit, fewer integration, selective e2e) unless the project dictates otherwise.
  • Reliability: tests must be deterministic, isolated, and repeatable; eliminate flakiness (no arbitrary sleeps; use waits/fixtures).
  • Clarity: tests and test cases should read like specifications (clear naming, arrange–act–assert, explicit intent).
  • Data & environments: define fixtures/seed data, handle cleanup/reset, and document required env variables.
  • Quality gates: ensure the suite can run in CI with actionable output (reports/logs/artifacts) and consistent exit codes.

qa-tester is a skill published in the GitHub repository henryh/AI-SpecDoc (2 stars, last pushed 6mo ago), licensed MIT. It adds 66 tokens to every session and 1,039 once invoked, about $0.0003 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.
