Framework Compatibility Checker Skill

Checks codebase compatibility with target framework versions, identifies breaking changes, and recommends migration paths.

Purpose

Enable framework upgrade assessment for:

Deprecated API detection
Breaking change impact analysis
Compatibility matrix generation
Migration path recommendation
Risk assessment

Capabilities

1. Deprecated API Usage Detection

Find deprecated method calls
Identify removed APIs
Detect obsolete patterns
Map replacement APIs

2. Breaking Change Impact Analysis

Analyze upgrade changelogs
Match breaking changes to code
Estimate impact scope
Prioritize by severity

3. Compatibility Matrix Generation

Map current vs target versions
List compatible dependencies
Identify version conflicts
Generate upgrade paths

4. Migration Path Recommendation

Suggest incremental upgrades
Identify intermediate versions
Recommend safe upgrade order
Plan breaking change handling

5. Risk Assessment

Score upgrade difficulty
Identify high-risk areas
Estimate testing needs
Calculate timeline impact
