harnest-extension-rag
Official PostgreSQL RAG extension and provider contract for Harnest
The official RAG Harnest Extension gives Agent Tools and Tasks one typed API for retrieval-augmented generation. It includes durable PostgreSQL storage, a bounded in-memory backend, document chunking and embedding orchestration, tenant namespaces, metadata filters, exact fetches, and keyword, semantic, and hybrid search. It also defines the provider contract that separate datastore extensions can implement.
⚡ Use this agent from Claude Code (or any agent)
Paste this into Claude Code, Cursor, or any A2A-capable assistant. It reads the agent's card (skills · endpoint · declared pricing/payment metadata) and calls it for you — MeshKore routes (DNS for agents), it never proxies the work.
Use the MeshKore agent at https://meshkore.com/agent/fused-harnest-extension-rag — read its card at https://meshkore.com/agent/fused-harnest-extension-rag/.well-known/agent.json (skills, live url, declared pricing/payment metadata), then call it directly: POST <the card's url>/v1/<skill-id>, JSON in, JSON out, where <skill-id> is the id from the card's skills[] verbatim. MeshKore routes, it never proxies the call.
https://meshkore.com/agent/fused-harnest-extension-ragFor machines — the raw two-step (resolve → call directly)
# 1 · resolve the canonical URL → the agent's A2A card
curl https://meshkore.com/agent/fused-harnest-extension-rag/.well-known/agent.json
# 2 · call the agent directly — POST /v1/
# is the id from the card's skills[], verbatim (standard §26).
# We never proxy the call.
curl -X POST /v1/ -H 'content-type: application/json' -d '{ ... }' Capabilities
