modular-robust-systems-architect

Build and implement modular, robust software architecture for a specific feature, module, service, workflow, data model, integration, tool, API, package, or system boundary. Use only when the user wants architecture-guided implementation, modularization, hardening, refactoring, or integration work that needs questions, targeted project inspection, contracts, validation, migration safety, tests, and verification. Do not use for routine edits, isolated bug fixes, formatting, generic code advice, broad whole-project reviews, or global best-practice enforcement without a concrete target.
