v0.6.0 — Pipeline Architecture + Code Compression

Pipeline Architecture + Code Compression

Toonify MCP now compresses source code in addition to structured data — reducing token usage on TypeScript, Python, and Go files that previously got 0% optimization.

Highlights

• Pipeline engine — modular Detector → Router → Compressor → Evaluator architecture, extensible via Compressor interface
• Code compression — 6 heuristic layers from safe to aggressive:
  1. Merge consecutive blank lines
  2. Remove inline comments
  3. Remove comment-only lines (preserves TODO/FIXME, JSDoc/docstring summaries)
  4. Shorten deep import paths
  5. Summarize consecutive imports (>500 tokens)
  6. Collapse repetitive patterns (>500 tokens)
• Hook upgraded — PostToolUse hook now detects and compresses source code (Layers 1-4)
• Full backwards compatibility — all external APIs unchanged, TokenOptimizer refactored to facade

v0.5.0 — Quality, Security & Accuracy Update

What's New

Plugin & Marketplace

• PostToolUse hook fully implemented — auto-optimizes Read, Grep, Glob, WebFetch results
• Marketplace install fixed — claude plugin marketplace add PCIRCLE-AI/toonify-mcp works correctly

Accuracy

• Token counting uses raw tiktoken BPE — no inflated language multipliers
• Benchmark-verified savings: avg 48%, median 53%, range 25-66%
• YAML detection hardened — no longer misdetects plain text as YAML
• CSV parser handles quoted fields ("Smith, John")

Security & Reliability

• 10 security vulnerabilities fixed (yaml DoS, picomatch ReDoS, qs bypass)
• DoS protection: 10MB input size limit, safe RegExp pre-compilation
• Path traversal protection on persistent cache paths
• Atomic file writes prevent data corruption
• WASM resource cleanup on process shutdown
• Async disk I/O — no event loop blocking
• All async persistence errors properly handled

Tooling

• TypeScript 6.0, MCP SDK 1.29, Jest 30
• 157 tests (up from 75), all modules covered
• Version read from package.json at runtime (no hardcoded strings)

v0.4.0 - Enhanced Caching with Critical Bug Fixes

🚀 What's New in v0.4.0

✨ Enhanced Caching System

• LRU Cache with Least Recently Used eviction strategy
• TTL Expiration (default: 1 hour)
• Optional Disk Persistence for cross-session cache reuse
• 50-500x Performance Improvement on cache hits (0.1ms vs 5-50ms)

🛠️ Critical Bug Fixes (6 issues)

• ✅ Fixed race conditions in PersistentCache with operation serialization
• ✅ Fixed excessive disk I/O with batched writes (90%+ reduction)
• ✅ Optimized updateStats() from O(n) to O(1)
• ✅ Fixed false cache hits by including metadata in keys
• ✅ Added missing config validation
• ✅ Added error handling to all MCP cache tools

🧪 Test Improvements

• ✅ All 122 tests passing (was 105)
• ✅ Fixed 8 test issues
• ✅ Zero TypeScript errors

📦 New MCP Tools

• clear_cache - Clear all cached optimization results
• get_cache_stats - Get detailed cache statistics
• cleanup_expired_cache - Remove expired entries

📚 Documentation

• New docs/CACHE.md with comprehensive cache documentation
• Updated README with cache management section
• Added Taiwan attribution statement

🎯 Performance Metrics

• Cache hit: ~0.1ms (instant return)
• Cache miss: ~5-50ms (optimization + store)
• Memory usage: ~2-5 KB per entry, ~1-2.5 MB for 500 entries

See CHANGELOG.md for complete details.
