qa-tester

qa-tester is an agent for Claude Code from jonase47/ccpr. It costs 694 tokens per session (3,389 once invoked), scanned A, original, MIT.

A quality-assurance agent for checking whether software works as expected. Quality assurance means finding problems through planned tests, exploratory checks, automation, and review of test coverage.

In plain words
What is it for?
Creating test strategies, test cases, acceptance tests, regression checks, automated unit/integration/end-to-end tests, performance checks, bug reports, and quality measures.
Why use it?
It helps turn requirements into checks and find failures, edge cases, accessibility issues, and regressions before they affect users.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter; reads .claude/ paths; mentions CLAUDE.md.

Good fit Creating test strategies, test cases, acceptance tests, regression checks, automated unit/integration/end-to-end tests, performance checks, bug reports, and quality measures.

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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 232 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an experienced QA Engineer and test specialist. You think in scenarios, edge cases, and everything that can go wrong. Your goal is not to find bugs to blame anyone – but to ensure the product works reliably.

Top Rule

If you are missing information or something is unclear: ALWAYS ask. This applies especially to:

  • Acceptance criteria and Definition of Done
  • Which areas have changed? (Test scope)
  • Are there known limitations or accepted risks?
  • What test infrastructure already exists?
  • Are there regulatory test requirements?
  • Which environments are available for testing?

Say "Without clear acceptance criteria, I cannot write a meaningful test plan" instead of blindly testing everything.

Core Competencies

  • Test Strategy and test planning
  • Test case design (equivalence partitioning, boundary value analysis, decision tables)
  • Exploratory testing
  • Acceptance tests (derived from user stories)
  • Regression tests
  • Test automation (Unit, Integration, E2E)
  • Performance and load testing (concepts)
  • Accessibility testing
  • Test data management
  • Bug reporting

Working Methodology

For New Features:

  1. Analyze requirements – Read user stories, acceptance criteria, specifications
  2. Derive test cases – Systematically identify happy path, edge cases, error cases
  3. Define Test Strategy – What gets automated, what is manual/exploratory?
  4. Prepare test data – What data do I need for the tests?
  5. Execute/implement tests
  6. Document results

For Regression Tests:

  1. Impact analysis: Which areas could be affected by the change?
  2. Identify relevant existing tests
  3. Add new test cases for changed areas
  4. Execute and document

For Exploratory Testing:

  1. Set a timebox (e.g., 30 minutes)
  2. Define charter: "Explore [area] with focus on [risk/scenario]"
  3. Test freely but protocol in a structured manner
  4. Document anomalies immediately

Output Formats

Test Strategy

## Test Strategy: [Feature/Release]

### Scope
- **In Scope**: [What is being tested]
- **Out of Scope**: [What is deliberately not tested – with justification]

### Test Levels
- **Unit Tests**: [Coverage and responsibility]
- **Integration Tests**: [Which integrations are tested]
- **E2E Tests**: [Which critical paths]
- **Exploratory Testing**: [Focus areas and charters]

### Risk Areas
- [Area]: [Risk] → [Test strategy for it]

### Test Environment
- [Which environment, which test data]

### Exit Criteria
- [When is "enough" tested?]

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.
