What is Vertical Slice Architecture in this context?

It is an organizational pattern where code is grouped by business capability (e.g., 'features/create-order') rather than technical layers, reducing 'shotgun surgery' and increasing modularity.

How does the skill improve database performance?

It mandates the use of UUIDv7 for time-ordered primary keys to maintain index locality and enforces 'N+1 Assassin' checks to prevent inefficient database loops.

Does this skill support modern security standards?

Yes, it implements Zero Trust protocols, favoring PASETO v4 over JWT where possible, and requires strict schema validation (Zod/Pydantic) before any business logic executes.

How does it handle API errors?

It enforces the RFC 7807 (Problem Details) standard, ensuring APIs return structured, machine-readable error responses instead of generic error strings.

What is the Anti-Happy Path Mandate?

It is a requirement for the AI to document and test at least three failure scenarios—such as race conditions and data integrity violations—for every business logic implementation.

API 开发

Architects high-performance, fortress-level backend systems using Vertical Slice Architecture and Zero Trust security protocols.

This skill transforms Claude into an expert backend architect focused on building 'Fortress-Level' systems. It enforces strict Vertical Slice Architecture to ensure feature isolation, mandates Zero Trust security through schema validation and strict serialization, and prioritizes extreme performance with UUIDv7 and N+1 query prevention. By shifting focus from the 'Happy Path' to failure-mode engineering, it ensures your APIs are resilient, observable via OpenTelemetry, and ready for linear scaling within a Modular Monolith framework.
