service-communication-audit

Systematic audit of how services talk to each other. Not just finding broken wires — questioning whether each wire should exist, in which direction, at what rate, and what comes back.

The core principle: deep modules with simple interfaces, not webs of shallow wiring. The consumer sees one health surface, one response, one interface. The implementation behind it can be as complex as needed — the consumer doesn't know or care. Every design decision filters through: "does this expose internal wiring to the consumer, or does it stay behind the module boundary?"

The full field guide is at references/communication-audit-guide.md (40 principles). Do NOT summarize the guide in prompts — workers read it directly.

在分析、設計或修復服務通訊方式時使用 - 特別是當通訊不穩定、單向、即發即棄、缺乏背壓或沒有恢復路徑時。涵蓋服務間同步、連接生命週期、滴答率分析、故障模式映射和自癒系統的協議設計。當使用者提及服務之間的不穩定、同步問題、重新連線問題或要求檢查兩個系統如何相互通訊時使用。 來源：cygnusfear/agent-skills。
