Release v2.2.0

DevMind MCP v2.2.0

Major Features

AI Enhancement Suite - 7 new intelligent modules for automated context processing:

1. Smart Query Enhancer

• 11 search templates for code_search, bug_fix, test_search, etc.
• 266+ Chinese-English synonym mappings for improved recall
• Query intent detection with automatic keyword expansion
• File type weighting based on query intent

2. Auto Memory Classifier

• 18 context types automatic classification (CODE_CREATE, CODE_MODIFY, BUG_FIX, etc.)
• Force remember detection for IMPORTANT/CRITICAL keywords
• Memory tier decision: silent/notify/none
• Impact level assessment: breaking/major/minor/patch

3. Context Enricher

• 25+ programming language detection
• Function/class/component extraction from code
• Business domain analysis (15 domains: auth, payment, database, API, etc.)
• Issue/PR number extraction (#123, PR #456 patterns)
• Auto tag generation and code quality scoring

4. Batch Processor

• 100+ item parallel processing for bulk operations
• Multi-file change aggregation with transaction support
• Configurable concurrency control with deduplication
• Large batch optimization (1000+ → 100 items)

5. Performance Optimizer

• Multi-level caching with LRU + TTL strategy
• Retry mechanism with exponential backoff (3 attempts default)
• Performance monitoring with metrics tracking
• Decorator pattern: @cached, @monitored

6. Session Auto-Caching

• Cross-tool session awareness and automatic reuse
• 50%+ reduction in duplicate database queries

7. Enhanced File Detection

• Git integration for detecting modified/staged files
• Content analysis for extracting file paths
• Multi-file auto-detection converting to files_changed format
• Confidence-based file suggestion ranking

Technical Improvements

MCP Server Integration

• All 7 AI enhancement modules fully integrated into handleRecordContext and handleSemanticSearch
• Automatic type classification: No need to manually specify context_type
• Query enhancement: Automatic synonym expansion and intent detection
• Context enrichment: Automatic metadata extraction (functions, business domains, tags)

Testing Results

• 33 test cases with 87.88% pass rate
• Performance benchmarks: 3ms classification, 2ms enrichment, 1ms query enhancement (100 operations)
• TypeScript compilation: No errors, full build success

Code Statistics

Total Added: ~3,600 lines across 8 files

• src/mcp-server.ts: +104 lines (AI integration)
• src/session-manager.ts: +193 lines (auto-caching)
• src/utils/query-enhancer.ts: +524 lines (search enhancement)
• src/utils/auto-memory-classifier.ts: +499 lines (auto-classification)
• src/utils/context-enricher.ts: +597 lines (context enrichment)
• src/utils/batch-processor.ts: +538 lines (batch processing)
• src/utils/performance-optimizer.ts: +574 lines (performance)
• test-ai-enhancements.js: +527 lines (test suite)

User Experience

Before:

• Manual context type specification required
• Basic keyword search with limited recall
• No automatic metadata extraction
• Manual file tracking needed

After:

• AI automatically classifies context types with 70%+ confidence
• Intelligent search with synonym expansion and template matching
• Automatic extraction of functions, classes, business domains, tags
• Complete file change tracking with Git integration

Backward Compatibility

• 100% backward compatible: All existing API calls work unchanged
• No configuration required: AI enhancements activate automatically
• Opt-in behavior: If user provides files_changed, auto-detection is skipped

Version Upgrade

• package.json: 2.1.15 → 2.2.0
• src/mcp-server.ts: Version string updated to 2.2.0
