zvec-local-rag-service

Run local RAG search with Ollama embeddings and zvec.

Included files

• scripts/rag-service.mjs → HTTP service implementation
• scripts/manage.sh → bootstrap/start/stop/restart/health/ingest/search
• references/launchd.plist.template → macOS LaunchAgent template

Prerequisites

• Node.js 18+
• Ollama daemon running
• Embedding model (default): mxbai-embed-large

Prepare model once:

ollama pull mxbai-embed-large

Quick start

From the skill directory:

scripts/manage.sh bootstrap
scripts/manage.sh install-launchd   # writes plist, inspect once
scripts/manage.sh start
scripts/manage.sh health

Ingest and search:

scripts/manage.sh ingest ./docs
scripts/manage.sh search "your query"

Install + smoke test (copy/paste)

# 1) prerequisites
ollama pull mxbai-embed-large

# 2) bootstrap and start service
scripts/manage.sh bootstrap
scripts/manage.sh install-launchd
scripts/manage.sh start

# 3) verify health
scripts/manage.sh health

# 4) create tiny test corpus
mkdir -p ./docs
cat > ./docs/sample.md <<'EOF'
Zvec + Ollama enables local semantic search.
EOF

# 5) ingest + query
scripts/manage.sh ingest ./docs
scripts/manage.sh search "local semantic search with ollama"

Endpoints

• GET /health
• POST /ingest with { "dir": "./docs", "reset": true }
• POST /search with { "query": "...", "topk": 5 }

Persistence (macOS launchd)

Install and enable LaunchAgent:

scripts/manage.sh install-launchd
scripts/manage.sh start
scripts/manage.sh status

Remove LaunchAgent:

scripts/manage.sh uninstall-launchd

Always inspect generated plist before enabling persistence:

• ~/Library/LaunchAgents/com.openclaw.zvec-rag-service.plist

Config via env vars

• RAG_HOST (default 127.0.0.1)
• RAG_PORT (default 8787)
• OLLAMA_URL (default http://127.0.0.1:11434)
• OLLAMA_EMBED_MODEL (default mxbai-embed-large)
• RAG_BASE_DIR (default ~/.openclaw/data/zvec-rag-service)
• ALLOW_REMOTE_OLLAMA (default false, blocks non-local OLLAMA_URL)
• ALLOW_NON_LOOPBACK_HOST (default false, blocks externally reachable bind host)

Notes

• Secure defaults: loopback-only service + loopback-only Ollama.
• Remote embedding/host binding require explicit opt-in env flags.
• launchd operations are macOS-specific. On non-macOS, run with scripts/manage.sh start (manual mode).
