production-grade

Principle-engineering posture for production-grade code. Problem-classification (A/B/C) before implementing, plans before code, simplest-correct-solution-first (YAGNI ladder: stdlib/native before deps, delete over add), math-first (closed-form), ACM-grade algorithms, EXPLAIN-first DBs with data-migration plans, never-N+1, idempotent-atomic writes, realtime-first, concurrent-by-default, graph-aware schemas, validate-at-borders, observable-surfaces (SEO/a11y/perf), LLM-as-typed-pipelines, paradigm-fluent (SOLID+GoF / FP), 12-Factor-aware, cost-aware-CI, surgical PRs, over-engineering audit, TDD-steered E2E, runtime-coherent infrastructure, dependency-remediation, migration-audit, evidence-linked security, currency-checked. Reads the repo first, matches conventions, pulls latest docs over training recall, defers to peer skills on their lanes. Substrate-agnostic. Use for non-trivial planning, design, implementation, review, refactoring, RCA, over-engineering cleanup, and hardening inherited or generated code.

适合你，如果你需要确保代码达到生产级标准，涵盖设计、实现、审查和加固。
