# Cross-Language Analysis Implementation Status

## Current Status - Sprint 52

### Documentation and Features

- ✅ Documentation created with detailed descriptions of polyglot analysis tools
- ✅ Feature description and technical architecture documented
- ✅ Test fixtures created for Java, Kotlin, and TypeScript integration
- ✅ Test strategy defined with both unit and integration tests

### Core Components

- ✅ Polyglot AST Framework
  - ✅ `UnifiedNode`: Language-agnostic representation of code elements
  - ✅ `Language` enum and `NodeKind` enum
  - ✅ Support for cross-language references
  - ✅ Basic attribute system for language-specific metadata
  
- ✅ Cross-Language Analysis
  - ✅ `CrossLanguageDependencies`: For analyzing relationships between languages
  - ✅ Dependency resolution algorithm
  - ✅ DOT graph visualization format
  
- ✅ MCP Tools
  - ✅ `analyze_polyglot`: MCP tool for analyzing cross-language relationships
  - ✅ `detect_language_boundaries`: MCP tool for identifying interoperability points
  - ✅ Detailed schemas defined for inputs and outputs
  - ✅ Recommendations for common language pairs

### Test Suite

- ✅ Unit tests for polyglot AST node creation
- ✅ Integration tests for cross-language dependency detection
- ✅ Test fixtures for Java, Kotlin, and TypeScript
- ✅ MCP tool integration tests

## Current Issues

- ⚠️ Import errors due to AstItem model mismatch
- ⚠️ Language-specific AST visitors not available:
  - `KotlinAstVisitor` (requires "kotlin-ast" feature)
  - `ScalaAstVisitor` (not implemented)
  - `TypeScriptAstVisitor` (not implemented)
  - `JavaScriptAstVisitor` (not implemented)
- ⚠️ Compilation errors in dependency detection logic (borrow checker issues)
- ⚠️ Unused imports and variables

## Next Steps

### Short Term (Sprint 52 Completion)

1. Address compiler errors:
   - Fix borrow checker issues in `CrossLanguageDependencies`
   - Replace `AstItem` usage with custom structure if needed
   - Add feature flags for language-specific implementations
   
2. Create minimal implementations of language mappers:
   - Implement stub versions of missing `*AstVisitor` classes
   - Create feature flags for each language
   - Implement basic AST mapping for critical languages

3. Complete integration tests:
   - Finish and make existing integration tests pass
   - Add more comprehensive test scenarios
   - Create test fixtures with real cross-language dependencies

### Medium Term (Sprint 53)

1. Improve language-specific AST mapping:
   - Implement comprehensive AST visitors for Java, Kotlin, and TypeScript
   - Add support for accurate name resolution across languages
   - Implement comprehensive type mapping

2. Enhance dependency detection:
   - Improve confidence scoring for cross-language references
   - Add support for more relationship types
   - Implement semantic analysis for better dependency detection

3. Expand MCP tools:
   - Add more detailed recommendations for common language combinations
   - Support more language pairs (Python, Go, C++, etc.)
   - Add visualization tools for cross-language dependencies

### Long Term

1. Refactoring capabilities:
   - Cross-language rename refactoring
   - API boundary enforcement
   - Schema validation for cross-language contracts

2. AI-assisted boundary management:
   - ML-based detection of problematic boundaries
   - Automated boundary documentation generation
   - Suggestion system for improving interoperability
   
3. Cross-language test generation:
   - Generate tests for cross-language boundaries
   - Detect regressions in interoperability
   - Enforce API contracts across language boundaries
