Action skill — Semantic search operations: BM25, vector search, hybrid search, reindexing.

Semantic Search — qmd

Search the vault by meaning using qmd, a local semantic search engine for markdown. BM25 + vector search + LLM re-ranking, all local. No cloud APIs.

Setup (One-Time)

If qmd is not installed:

brew install oven-sh/bun/bun        # Bun runtime (if not installed)
bun install -g github:tobi/qmd      # qmd itself

Register the vault as a collection:

qmd collection add "<vault-path>" --name vault

Build initial embeddings (~2GB models downloaded on first run):

qmd embed

Index stored at ~/.cache/qmd/index.sqlite — outside vault, no gitignore needed.

Commands

Reindex

When invoked with --reindex or after batch changes to the vault:
