reliability

Use when an approved system design exists and the team needs production-grade reliability architecture before implementation and platform hardening. Produces service-level objectives and error-budget policy, dependency criticality analysis, failure-mode architecture, graceful-degradation behavior, blast-radius isolation, redundancy and failover posture, disaster-recovery strategy with RTO/RPO, chaos-validation planning, release-safety mechanisms, and implementation handoff guidance. Do not use for telemetry instrumentation, runbook authoring, oncall rotation design, performance budgets, or security threat modeling; use operations, performance, or security instead.
