Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install colbert-multi-vector-retrieval

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 helps you use ColBERT as a first-stage retriever, not only as a reranker: MaxSim scoring, PLAID index, storage cost of token-level vectors, Qdrant multi-vector setup and a two-stage dense-then-ColBERT pipeline. It says when ColBERT beats dense retrieval with reranking.
