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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00056 | $0.00273 |
| Opus 5.5 | $0.00022 | $0.00109 |
| Sonnet 5.5 | $0.00011 | $0.00055 |
| Haiku 4.5 | $0.00006 | $0.00027 |
Grade A, and why
testing-strategy 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 5d 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.
This is a copy
100% identical to testing-strategy — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Testing Strategy
Design effective testing strategies balancing coverage, speed, and maintenance.
Testing Pyramid
/ E2E \ Few, slow, high confidence
/ Integration \ Some, medium speed
/ Unit Tests \ Many, fast, focused
Strategy by Component Type
- API endpoints: Unit tests for business logic, integration tests for HTTP layer, contract tests for consumers
- Data pipelines: Input validation, transformation correctness, idempotency tests
- Frontend: Component tests, interaction tests, visual regression, accessibility
- Infrastructure: Smoke tests, chaos engineering, load tests
What to Cover
Focus on: business-critical paths, error handling, edge cases, security boundaries, data integrity.
Skip: trivial getters/setters, framework code, one-off scripts.
Output
Produce a test plan with: what to test, test type for each area, coverage targets, and example test cases. Identify gaps in existing coverage.
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.

testing-strategy is a skill published in the GitHub repository Blushyes/reef (83 stars, last pushed 5d ago), licensed Apache-2.0. It adds 56 tokens to every session and 273 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to testing-strategy, differing in 0 lines, and is treated as a copy.
Other skills, from other repositories
memstack-development-test-writer
Use this skill when the user says 'write tests', 'add tests', 'test coverage', 'unit tests', 'integration tests', 'component tests', 'mocking', 'edge cases', or needs to generate tests with proper mocking and edge case coverage. Do NOT use for refactoring plans or database migrations.
ios-testing
Invoke any time a user is writing iOS/Swift tests or asking why tests behave a certain way — including XCTest versus Swift Testing (@Test/#expect) choices, async ViewModel tests with @Observable or @Published, snapshot testing across device sizes, mocking protocols for dependency injection, setUp/tearDown lifecycle…
factory-testing
Testing conventions across builds. Vitest + Playwright as the locked stack; tests co-located in tests next to the code they verify; shared test primitives (provider wrappers, mock factories) centralized in src/lib/test-utils.tsx; coverage thresholds enforced at the merge gate (CI ownership lives in factory-ci.md).…
dev-testing
A testing guide that defines when to use unit, integration, API, and end-to-end tests. Unit tests check small pieces of code, while end-to-end tests check a full user flow.
testloop
Implementation-test-fix feedback loop.
testing-strategy
Test selection and scope guidance: tiers, marks, batching, cross-module regressions. Loaded by the testing rule module. Triggers: 'which tests should I run', 'test scope', 'test tiers'. NOT for: writing tests (use test-driven-development) or fixing broken tests (use fixing-tests).
