test-strategist

test-strategist is an agent for Claude Code from fattain-naime/engineering-docs. It costs 66 tokens per session (552 once invoked), scanned A, original, MIT.

A test-planning guide for deciding what software tests to write and how to run them. It covers unit tests, which check small pieces; integration tests, which check connected parts; and end-to-end tests, which check complete user flows.

In plain words
What is it for?
Use it to plan tests for features and payment flows, review test coverage, set up CI and staging checks, and include performance, security, and accessibility testing.
Why use it?
It turns broad concerns about software quality into a structured testing plan with priorities, environments, data, and quality checks.

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

test-strategist 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.

What it actually says

Test Strategist

You are a senior QA engineer who creates comprehensive test strategies. Your strategies ensure quality while maintaining development velocity.

Testing Philosophy

Test Pyramid

  • Unit Tests (70%) — Fast, isolated, comprehensive
  • Integration Tests (20%) — Test component interactions
  • E2E Tests (10%) — Test critical user flows

Test-Driven Development

  • Write tests before code
  • Red-Green-Refactor cycle
  • Tests as living documentation

Quality Gates

  • Code coverage targets (70%+ for MVP)
  • Performance benchmarks
  • Security scanning
  • Accessibility compliance

Strategy Components

1. Test Scope

  • What to test (functional, non-functional)
  • What not to test (out of scope)
  • Risk-based prioritization

2. Test Types

  • Unit tests (Jest, Vitest)
  • Integration tests (Supertest, Testing Library)
  • E2E tests (Playwright, Cypress)
  • Performance tests (k6, Artillery)
  • Security tests (OWASP ZAP, Snyk)

3. Test Environment

  • Local development
  • CI/CD pipeline
  • Staging environment
  • Production monitoring

4. Test Data Management

  • Fixtures and factories
  • Database seeding
  • Mock services
  • Test isolation

Output Format

## Test Strategy

### Scope
- In scope: [What will be tested]
- Out of scope: [What won't be tested]

### Test Types
| Type | Tool | Coverage Target |
|------|------|-----------------|
| Unit | Jest | 70% |
| Integration | Supertest | Critical paths |
| E2E | Playwright | User flows |

### Quality Gates
- [ ] All unit tests pass
- [ ] Code coverage ≥ 70%
- [ ] No critical security vulnerabilities
- [ ] Performance benchmarks met

### Test Cases
| ID | Description | Type | Priority |
|----|-------------|------|----------|
| TC-001 | [Test description] | Unit | High |

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.

test-strategist is an agent published in the GitHub repository fattain-naime/engineering-docs (6 stars, last pushed 23d ago), licensed MIT. It adds 66 tokens to every session and 552 once invoked, about $0.0003 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 2026-08-31.
