testcontainers-python specialist. Covers all container modules (PostgreSQL, MySQL, MongoDB, Redis, Kafka, RabbitMQ, MinIO, Elasticsearch, LocalStack), GenericContainer, wait strategies, Docker Compose, networks, pytest fixtures, and CI/CD integration. USE WHEN: user mentions "testcontainers", "docker in tests", "real database in tests", "test with real postgres/redis/kafka", asks about container fixtures or Docker-based testing. DO NOT USE FOR: Spring Boot testcontainers (Java) - use `spring-boot-integration`; Mocking HTTP - use `fastapi-testing`; Pure pytest patterns - use `pytest`
End-to-end type safety patterns for API development. Covers Zod-to-OpenAPI, ts-rest, Zodios, and contract testing. Use for ensuring type consistency between backend and frontend. USE WHEN: user mentions "type-safe API", "end-to-end types", "Zod to OpenAPI", "ts-rest", "Zodios", "contract testing", asks about "share types between frontend and backend", "type safety across API", "API contract", "Pact testing" DO NOT USE FOR: tRPC (use `trpc` instead); GraphQL (use `graphql` instead); Simple OpenAPI generation (use `openapi-codegen` instead); Non-TypeScript projects
Emulated Google OAuth 2.0 and OpenID Connect for local development and testing. Use when the user needs to test Google sign-in locally, emulate OIDC discovery, handle Google token exchange, configure Google OAuth clients, or work with Google userinfo without hitting real Google APIs. Triggers include "Google OAuth", "emulate Google", "mock Google login", "test Google sign-in", "OIDC emulator", "Google OIDC", "local Google auth", or any task requiring a local Google OAuth/OIDC provider.
Runs Fastly Compute WASM applications locally with Viceroy, specifically for Rust and Component Model projects. Use when starting a local Fastly Compute dev server with Viceroy, configuring fastly.toml for local backend overrides and store definitions, running Rust unit tests with cargo-nextest against the Compute runtime, debugging Compute apps locally, adapting core WASM modules to the Component Model, or troubleshooting local Compute testing issues (connection refused, missing backends, store config). For non-Rust Compute work or understanding the Compute API, prefer the fastlike skill instead — its source code is easier to understand as a Fastly Compute API reference.
Perses plugin testing: CUE schema unit tests with percli plugin test-schemas, React component tests, integration testing with local Perses server, and Grafana migration compatibility testing. Use for "test perses plugin", "perses plugin test", "perses schema test". Do NOT use for dashboard validation (use perses-lint).
Evaluate and improve skills through measured testing. Run trigger evaluations to test whether skill descriptions cause correct activation, optimize descriptions via automated train/test loops, benchmark skill output quality with A/B comparisons, and validate skill structure. Use when user says "improve skill", "test skill triggers", "optimize description", "benchmark skill", "eval skill", or "skill quality". Do NOT use for creating new skills (use skill-creator-engineer).
A/B test agent variants measuring quality and total session token cost across simple and complex benchmarks. Use when creating compact agent versions, validating agent changes, comparing internal vs external agents, or deciding between variants for production. Use for "compare agents", "A/B test", "benchmark agents", or "test agent efficiency". Do NOT use for evaluating single agents, testing skills, or optimizing prompts without variant comparison.
SAP Converged Cloud Go coding conventions extracted from sapcc/keppel and sapcc/go-bits PR reviews. Enforces architecture patterns, library usage rules, error handling conventions, testing patterns, and anti-over-engineering principles. Use when working in sapcc/* repos, when code imports github.com/sapcc/go-bits, or when targeting SAP CC code review standards. Do NOT use for general Go projects without sapcc dependencies.
Deterministic API endpoint validation with structured pass/fail reporting. Use when endpoints need smoke testing, health checks are required before deployment, or CI/CD pipelines need HTTP validation gates. Use for "validate endpoints", "check api health", "api smoke test", or "are endpoints working". Do NOT use for load testing, browser testing, full integration suites, or OAuth/complex authentication flows.
Run isolated eval and grading calls using CC 2.1.81 --bare mode. Constructs claude -p --bare invocations for skill evaluation, trigger testing, and LLM grading without plugin/hook interference. Use when running eval pipelines, grading skill outputs, benchmarking prompt quality, or testing trigger accuracy in isolation.

Write property-based tests using Hegel. Triggers on: "property-based tests", "PBT", "hegel tests", "test with random inputs", "generative tests", "test properties", "randomized testing"
