Core features: - Ebbinghaus forgetting curve engine with dynamic strength/stability - Multi-level memory compression (pluggable strategies, LLM-ready) - Cross-agent shared memory spaces with ACL and conflict detection - Memory versioning: update, supersede, restore, chain resolution - Multi-signal recall engine (recency + strength + relevance + importance) - 79 passing tests across 6 test files 🤖 Generated with [Qoder][https://qoder.com]
Add semantic compression strategies for memory management: - SemanticCompressionStrategy: LLM-powered memory summarization - HierarchicalSemanticStrategy: Multi-level L1/L2 compression - KeyExtractionStrategy: Extract key facts from memories - createSemanticCompressor: Factory function Features: - Configurable prompt templates - Metadata inclusion options - Fallback to rule-based compression on LLM failure - Importance and strength-based memory prioritization Reference: Inspired by claude-mem AI compression approach.
- Add src/semantic-search.ts: - EmbeddingProvider interface - OpenAIEmbeddings (text-embedding-3-small) - OllamaEmbeddings (nomic-embed-text) - SemanticSearchAdapter combining vector similarity with recall signals - Cosine similarity scoring with importance/recency boosting - Add examples/06_semantic_search.ts with full demo - Export new module from index.ts - Inspired by supermemory and Mem0 semantic patterns
- Add LLMImportanceScorer: analyze memory content and assign importance level - Batch scoring for multiple memories - Heuristic fallback when LLM is unavailable - Integrates with existing memory lifecycle closes #trending-2026-04-04
Inspired by kiwi-mem (2026-04-18 AI Trending): - DreamConsolidator: async background consolidation of weak memories - HierarchicalSummarizer: calendar-tier day/week/month digests
