srednoff888-art Mutation Testing Strategy
Use this skill for Programming tasks focused on mutation testing ideas, weak assertion detection, test suite hardening, critical logic coverage.
Workflow
- Clarify the user outcome, constraints, current stack, and definition of done.
- Inspect local source, artifacts, analytics exports, logs, designs, or docs before changing anything.
- Check official documentation when APIs, SDKs, policies, search behavior, accessibility rules, or production behavior may have changed.
- Compare proven open-source patterns for non-trivial choices and adapt ideas without copying incompatible code.
- Produce the smallest production-ready change or recommendation that satisfies the request.
- Validate with relevant evidence: tests, lint, typecheck, build, screenshots, crawl output, logs, analytics, or manual scenario.
- Report commands, files, findings, risks, and next steps clearly.
Focus Checklist
- Map inputs, owners, dependencies, and constraints.
- Prefer existing project conventions, design systems, and platform primitives.
- Include failure states, privacy/security implications, performance impact, and rollback where relevant.
- Separate facts from assumptions and mark any unverified claims.
- Keep recommendations actionable and prioritized by impact and risk.
Guardrails
- Do not chase 100 percent mutation scores where risk does not justify cost.
- Do not perform destructive, paid, production, publishing, account-changing, or externally visible actions without explicit user confirmation.
- Do not expose secrets, private keys, tokens, cookies, private analytics, personal data, or confidential business data.
- If validation is impossible, state why and provide a concrete manual verification path.
