+# Changelog
+
+All notable changes to the OpenClaw RAG Knowledge System will be documented in this file.
+
+## [1.0.0] - 2026-02-11
+
+### Added
+- Initial release of RAG Knowledge System for OpenClaw
+- Semantic search using ChromaDB with all-MiniLM-L6-v2 embeddings
+- Multi-source indexing: sessions, workspace files, skill documentation
+- CLI tools: rag_query.py, rag_manage.py, ingest_sessions.py, ingest_docs.py
+- Python API: rag_query_wrapper.py for programmatic access
+- Automatic integration wrapper: rag_context.py for transparent RAG queries
+- RAG-enhanced agent wrapper: rag_agent.py
+- Type filtering: search by document type (session, workspace, skill, memory)
+- Document management: add, delete, reset collection
+- Batch ingestion with intelligent chunking
+- Session parser for OpenClaw event format
+- Automatic daily updates via cron job
+- Comprehensive documentation: README.md, SKILL.md
+
+### Features
+- **Semantic Search**: Find relevant context by meaning, not keywords
+- **Local Vector Store**: ChromaDB with persistent storage (~100MB per 1,000 docs)
+- **Zero Dependencies**: No API keys required (all-MiniLM-L6-v2 is free and local)
+- **Smart Chunking**: Messages grouped by 20 with overlap for context
+- **Multi-Format Support**: Python, JavaScript, Markdown, JSON, YAML, shell scripts
+- **Automatic Updates**: Scheduled cron job runs daily at 4:00 AM UTC
+- **State Tracking**: Avoids re-processing unchanged files
+- **Debug Mode**: Verbose output for troubleshooting
+
+### Bug Fixes
+- Fixed duplicate ID errors by including chunk_index in hash generation
+- Fixed session parser to handle OpenClaw event format correctly
+- Fixed metadata conversion errors (all metadata values as strings)
+
+### Performance
+- Indexing speed: ~1,000 docs/minute
+- Search time: <100ms (after embedding load)
+- Embedding model: 79MB (cached locally)
+- Storage: ~100MB per 1,000 documents
+
+### Documentation
+- Complete SKILL.md with OpenClaw integration guide
+- Comprehensive README.md with examples and troubleshooting
+- Inline help in all CLI tools
+- Best practices and limitations documented
+
+---
+
+## [1.0.0] - 2026-02-11 (Enhancements)
+
+### Security & Metadata
+- Added package.json with OpenClaw skill metadata
+- Declared data storage path: ~/.openclaw/data/rag/
+- Explicitly stated: NO required environment variables
+- Added MIT License
+- Added CHANGELOG.md
+
+---
+
+## [Unreleased]
+
+### Planned
+- API documentation indexing from external URLs
+- Automatic re-indexing on file system events (inotify)
+- Better chunking strategies for long documents
+- Integration with external vector stores (Pinecone, Weaviate)
+- Webhook notifications for automated content processing
+- Hybrid search (semantic + keyword)
+- Query history and analytics
+- Export/import of vector database
+
+---

+# Install Python dependency
 cd ~/.openclaw/workspace/rag
 python3 -m pip install --user chromadb
 ```
 
+**No API keys required** - This system is fully local:
+- Embeddings: all-MiniLM-L6-v2 (downloaded once, 79MB)
+- Vector store: ChromaDB (persistent disk storage)
+- Data location: `~/.openclaw/data/rag/` (auto-created)
