API Compatibility Analyzer Skill

Analyzes API changes between versions to detect breaking changes, assess consumer impact, and suggest migration strategies.

Purpose

Enable API versioning management for:

  • Breaking change detection
  • Deprecation analysis
  • Version comparison
  • Consumer impact assessment
  • Migration path suggestion

Capabilities

1. Breaking Change Detection

  • Detect removed endpoints
  • Identify removed fields
  • Find type changes
  • Flag required field additions

2. Deprecation Analysis

  • Track deprecated endpoints
  • Monitor deprecation timelines
  • Identify usage of deprecated APIs
  • Plan sunset schedules

3. Version Comparison

  • Compare OpenAPI specs
  • Generate detailed diffs
  • Categorize changes
  • Document migrations

4. Consumer Impact Assessment

  • Map affected consumers
  • Estimate migration effort
  • Identify high-impact changes
  • Prioritize notifications

5. Migration Path Suggestion

  • Recommend upgrade steps
  • Suggest compatibility layers
  • Propose versioning strategies
  • Design adapter patterns

6. Compatibility Layer Design

  • Design facade endpoints
  • Plan response translation
  • Handle version negotiation
  • Implement fallbacks
