Condition-based polling and retry patterns: exponential backoff, health checks, rate limit recovery, circuit breakers. Use when replacing arbitrary sleeps with condition checks, implementing retry logic, waiting for service availability, or handling API rate limits. Use for "wait for", "poll until", "retry with backoff", "health check", or "rate limit". Do NOT use for async event-driven architectures, distributed locking, or real-time guarantees.
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.
Right-sizes architecture to project scope. Prevents over-engineering by classifying projects into 6 tiers and constraining pattern choices accordingly. Use when designing architecture, selecting patterns, or when brainstorm/implement detect a project tier.
Expert knowledge for Azure Database for MySQL development including troubleshooting, best practices, decision making, architecture & design patterns, limits & quotas, security, configuration, integrations & coding patterns, and deployment. Use when deploying MySQL Flexible Server, tuning performance, configuring HA/networking, securing access, or integrating apps, and other Azure Database for MySQL related development tasks.

Enforces 10000% accuracy with balanced entries and seamless void/reversal mechanics. Use when building any financial, ERP, POS, or inventory system that needs proper accounting.
Use when you need to apply data-oriented programming best practices in Java — including separating code (behavior) from data structures using records, designing immutable data with pure transformation functions, keeping data flat and denormalized with ID-based references, starting with generic data structures converting to specific types when needed, ensuring data integrity through pure validation functions, and creating flexible generic data access layers.
