| rag | Complete RAG (Retrieval-Augmented Generation) system for OpenClaw. Indexes chat sessions, workspace code, documentation, and skills into local ChromaDB for semantic search. Enables finding past solutions, code patterns, and decisions instantly. Uses local embeddings (all-MiniLM-L6-v2) with no API keys required. Automatically ingests and updates knowledge base from ~/.openclaw/agents/main/sessions and workspace files. |
OpenClaw RAG Knowledge System
Retrieval-Augmented Generation for OpenClaw – Search chat history, code, docs, and skills with semantic understanding
Overview
This skill provides a complete RAG (Retrieval-Augmented Generation) system for OpenClaw. It indexes your entire knowledge base – chat transcripts, workspace code, skill documentation – and enables semantic search across everything.
Key features:
- 🧠 Semantic search across all conversations and code
- 📚 Automatic knowledge base management
- 🔍 Find past solutions, code patterns, decisions instantly
- 💾 Local ChromaDB storage (no API keys required)
- 🚀 Automatic AI integration – retrieves context transparently
Installation
Prerequisites
- Python 3.7+
- OpenClaw workspace
Setup
# Navigate to your OpenClaw workspace
cd ~/.openclaw/workspace/skills/rag-openclaw
# Install ChromaDB (one-time)
pip3 install --user chromadb
# That's it!
Quick Start
1. Index Your Knowledge
# Index all chat history
python3 ingest_sessions.py
# Index workspace code and docs
python3 ingest_docs.py workspace
# Index skill documentation
python3 ingest_docs.py skills
2. Search the Knowledge Base
# Interactive search mode
python3 rag_query.py -i
# Quick search
python3 rag_query.py "how to send SMS via voip.ms"
# Search by type
python3 rag_query.py "porkbun DNS" --type skill
python3 rag_query.py "chromedriver" --type workspace
python3 rag_query.py "Reddit automation" --type session
3. Check Statistics
# See what's indexed
python3 rag_manage.py stats
Usage Examples
Finding Past Solutions
Hit a problem? Search for how you solved it before:
python3 rag_query.py "cloudflare bypass selenium"
python3 rag_query.py "voip.ms SMS configuration"
python3 rag_query.py "porkbun update DNS record"
Searching Through Codebase
Find specific code or documentation:
python3 rag_query.py --type workspace "unifi gateway API"
python3 rag_query.py --type workspace "SMS client"
Quick Reference
Access skill documentation without digging through files:
python3 rag_query.py --type skill "how to monitor UniFi"
python3 rag_query.py --type skill "Porkbun tool usage"
Programmatic Use
From within Python scripts or OpenClaw sessions:
import sys
sys.path.insert(0, '/home/william/.openclaw/workspace/skills/rag-openclaw')
from rag_query_wrapper import search_knowledge, format_for_ai
# Search and get structured results
results = search_knowledge("Reddit account automation")
print(f"Found {results['count']} relevant items")
# Format for AI consumption
context = format_for_ai(results)
print(context)

How It Works
Indexing
Sessions:
- Reads
~/.openclaw/agents/main/sessions/*.jsonl - Handles OpenClaw event format (session metadata, messages, tool calls)
- Chunks messages (20 per chunk, 5 message overlap)
- Extracts and formats thinking, tool calls, results
Workspace:
- Scans for
.py,.js,.ts,.md,.json,.yaml,.sh,.html,.css - Skips files > 1MB and binary files
- Chunks long documents for better retrieval
Skills:
- Indexes all
SKILL.mdfiles - Organized by skill name for easy reference
Search
ChromaDB uses all-MiniLM-L6-v2 embeddings to convert text to vectors. Similar meanings cluster together, enabling semantic search by meaning not just keywords.
Automatic Integration
When the AI responds, it automatically:
- Searches the knowledge base for relevant context
- Retrieves past conversations, code, or docs
- Includes that context in the response
This happens transparently – the AI "remembers" your past work.

Performance
- Embedding model:
all-MiniLM-L6-v2(79MB, cached locally) - Storage: ~100MB per 1,000 documents
- Indexing: ~1,000 documents/minute
- Search: <100ms (after first query)
Troubleshooting
No Results Found
# Check what's indexed
python3 rag_manage.py stats
# Try broader query
python3 rag_query.py "SMS" # instead of "voip.ms SMS API endpoint"
Slow First Search
First search loads embeddings (~1-2 seconds). Subsequent searches are instant.
Duplicate ID Errors
# Reset and re-index
python3 rag_manage.py reset
python3 ingest_sessions.py
python3 ingest_docs.py workspace
ChromaDB Model Download
First run downloads embedding model (79MB). Takes 1-2 minutes. Let it complete.
Best Practices
Re-index Regularly
After significant work:
python3 ingest_sessions.py # New conversations
python3 ingest_docs.py workspace # New code/changes
Use Specific Queries
# Better
python3 rag_query.py "voip.ms getSMS method"
# Too broad
python3 rag_query.py "SMS"
Filter by Type
# Looking for code
python3 rag_query.py --type workspace "chromedriver"
# Looking for past conversations
python3 rag_query.py --type session "Reddit"
Document Decisions
After important decisions, add them manually:
python3 rag_manage.py add \
--text "Decision: Use Playwright for Reddit automation. Reason: Cloudflare bypass handles" \
--source "decision:reddit-automation" \
--type "decision"
Limitations
- Files > 1MB automatically skipped (performance)
- Python 3.7+ required
- ~100MB disk per 1,000 documents
- First search slower (embedding load)
Integration with OpenClaw
This skill integrates seamlessly with OpenClaw:
- Automatic RAG: AI automatically retrieves relevant context when responding
- Session history: All conversations indexed and searchable
- Workspace awareness: Code and docs indexed for reference
- Skill accessible: Use from any OpenClaw session or script
Security Considerations
⚠️ Important Privacy Note: This RAG system indexes local data, which may contain:
- API keys, tokens, or credentials in session transcripts
- Private messages or personal information
- Tool results with sensitive data
- Workspace configuration files
Recommended:
- Review session files before ingestion if concerned about privacy
- Consider redacting sensitive data from session files
- Use
rag_manage.py resetto delete the entire index when needed - The ChromaDB persistence at
~/.openclaw/data/rag/can be deleted to remove all indexed data - The auto-update script only runs local ingestion - no remote code fetching
Example Workflow
Scenario: You're working on a new automation but hit a Cloudflare challenge.
# Search for past Cloudflare solutions
python3 rag_query.py "Cloudflare bypass selenium"
# Result shows relevant past conversation:
# "Used undetected-chromedriver but failed. Switched to Playwright which handles challenges better."
# Now you know the solution before trying it!
