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

Recommended Agent Skills
Expand your agent's capabilities with these related and highly-rated skills.
gsd-tools
Central utility skill for GSD operations. Provides config parsing, slug generation, timestamps, path operations, and orchestrates calls to other specialized skills. Acts as the unified entry point that the original gsd-tools.cjs provided via its lib/ modules (commands, config, core, init).
model-profile-resolution
Resolve model profile (quality/balanced/budget) at orchestration start and map agents to specific models. Enables cost/quality tradeoffs by selecting appropriate AI models for each agent role.
verification-suite
Plan structure validation, phase completeness checks, reference integrity verification, and artifact existence confirmation. Provides the structured verification layer ensuring GSD artifacts are well-formed and complete.
state-management
STATE.md reading, writing, and field-level updates. Provides cross-session state persistence via .planning/STATE.md with structured fields for current task, completed phases, blockers, decisions, and quick tasks.
git-integration
Git commit patterns, formats, and conventions for GSD methodology. Provides atomic commits per task, structured commit messages, planning file commits, branch management, and milestone tag operations.
frontmatter-parsing
YAML frontmatter parsing and manipulation for .planning/ documents. Provides read, write, update, query, and validation operations on frontmatter blocks in GSD markdown artifacts.
