**SRE Product Acceptance Criteria for AI-generated code**: Review and enforce production-readiness standards on code that AI (or humans) produce. Covers structured logging, metrics exposure, health checks, graceful shutdown, retry/circuit-breaker patterns, and timeout policies. Use this skill whenever reviewing code for production readiness, writing acceptance criteria for a service, auditing observability of an existing codebase, or when the user says things like "is this production ready", "add logging", "add metrics", "review for SRE", "acceptance criteria", "observability", "production checklist". Trigger even if the user just asks to "review this service" or "make this ready for prod" — those are exactly the moments this skill should activate.
