  • Track deprecation timelines and milestones
  • Inject deprecation warnings in SDK code
  • Send sunset notifications to API consumers
  • Generate migration documentation automatically
  • Monitor deprecated endpoint usage
  • Configure Sunset and Deprecation HTTP headers
  • Implement gradual deprecation with usage thresholds
  • Archive deprecated documentation appropriately

Target Processes

  • Backward Compatibility Management
  • API Versioning Strategy
  • SDK Versioning and Release Management

Integration Points

  • Sunset header injection middleware
  • Deprecation annotation processors
  • Usage analytics systems
  • Email/notification services
  • Documentation platforms

Input Requirements

  • Deprecation policy and timelines
  • Affected endpoints/features list
  • Replacement/migration paths
  • Consumer notification requirements
  • Usage monitoring access

Output Artifacts

  • Deprecation timeline documentation
  • SDK deprecation annotations
  • Migration guides
  • Sunset header configurations
  • Consumer notification templates
  • Usage monitoring dashboards
  • Archived documentation

Usage Example

skill:
  name: deprecation-manager
  context:
    deprecationPolicy: ./docs/deprecation-policy.md
    features:
      - featureId: legacy-auth
        deprecationDate: "2024-06-01"
        sunsetDate: "2024-12-01"
        replacement: oauth2-flow
    notificationChannels:
      - email
      - dashboard
      - sdkWarnings
    usageThreshold: 100

Best Practices

  1. Announce deprecations well in advance (6+ months)
  2. Provide clear migration paths with examples
  3. Monitor usage before sunset
  4. Send multiple reminder notifications
  5. Keep deprecated docs available but marked
  6. Implement gradual rate limiting before full sunset
