Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install hybrid-search-fusion

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent computes reciprocal rank fusion (RRF) or weighted linear fusion, tunes alpha on a gold set and uses native hybrid indexes in Pinecone, Qdrant or Weaviate. You get search that finds both exact terms and synonyms.
