This skill covers implementing a structured patch management program for OT/ICS environments where traditional IT patching approaches can cause process disruption or safety hazards. It addresses vendor compatibility testing, risk-based patch prioritization, staged deployment through test environments, maintenance window coordination, rollback procedures, and compensating controls when patches cannot be applied due to operational constraints or vendor restrictions.
Conducts comprehensive backend design reviews covering API design quality, database architecture validation, microservices patterns assessment, integration strategies evaluation, security design review, and scalability analysis. Evaluates API specifications (REST, GraphQL, gRPC), database schemas, service boundaries, authentication/authorization flows, caching strategies, message queues, and deployment architectures. Identifies design flaws, security vulnerabilities, performance bottlenecks, and scalability issues. Produces detailed design review reports with severity-rated findings, architecture diagrams, and implementation recommendations. Use when reviewing backend system designs, validating API specifications, assessing database schemas, evaluating microservices architectures, reviewing integration patterns, or when users mention backend design review, API design validation, database design review, microservices assessment, or backend architecture evaluation.
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.
First-time Perses setup pipeline: discover or deploy server, configure MCP connection, create initial project, add datasources, and verify connectivity. 4-phase pipeline: DISCOVER, CONNECT, CONFIGURE, VALIDATE. Use when setting up Perses for the first time, connecting Claude Code to an existing Perses instance, or onboarding a new team to Perses. Use for "perses onboard", "setup perses", "connect to perses", "perses getting started". Do NOT use for dashboard creation (use perses-dashboard-create) or server deployment details (use perses-deploy).
