Does it support industry-standard deprecation headers?

Yes, it provides implementation patterns for Deprecation, Sunset, and Link headers to programmatically inform clients about upcoming version retirements.

What is the Version Adapter Pattern?

It is a coding pattern used to transform data between different API versions, allowing the backend to support older response formats without maintaining separate logic for every version.

How does it handle breaking changes?

The skill helps you identify when a change requires a version bump and provides patterns like the Version Adapter Pattern to maintain compatibility while your data structures evolve.

Which versioning method does this skill recommend?

While it supports several methods, it primarily recommends URL path versioning (e.g., /api/v1/) for its clarity, ease of routing, and cache-friendliness.

Can it help with migration timelines?

Yes, it includes a structured phase-out timeline including deprecation periods, sunset announcements, read-only windows, and final shutdown procedures.

API開発

Implements professional API versioning strategies and deprecation workflows to maintain backward compatibility and smooth migration paths.

概要

This skill provides a comprehensive framework for managing the lifecycle of your web services, from selecting the right versioning method—be it URL path, custom headers, or query parameters—to implementing complex version adapter patterns. It guides developers through the nuances of distinguishing between safe and breaking changes, ensures industry-standard deprecation headers like Sunset and Link are correctly applied, and establishes structured migration timelines. It is an essential tool for backend engineers building production-grade APIs that must evolve without disrupting existing clients or breaking downstream integrations.
