upstash / vector-js

@upstash/vector is a connectionless client built for places a persistent connection doesn't fit — serverless functions, Cloudflare Workers, Next.js, client-side and WebAssembly code — talking to the index over REST instead of a driver. The skill walks through the shape of that API: upserting dense, sparse, or hybrid vectors, or plain text via a data field that Upstash embeds server-side; querying by vector or by raw text with metadata filtering; and the surrounding index operations — fetch, range, delete, reset, info, random, and namespace management (listNamespaces, deleteNamespace) for partitioning one index into isolated subsets.

This is for someone who has already chosen Upstash Vector and wants an agent that writes correct calls against this specific client, not someone evaluating vector databases — the skill assumes the index and the choice are made. It buys nothing without one: the README's own quick start opens with creating an index in the Upstash console before any code runs.
