Covers the DESI spectroscopic survey — data products, environment variables, production releases (mountain names), data layout under $DESI_SPECTRO_REDUX, Python I/O with desispec, and DESI-specific compute conventions. Most DESI runtime tools (desimodules, desispec, redrock, $SPECPROD, $DESI_ROOT) require NERSC; combine with the nersc skill for job submission and cluster setup. Use this skill whenever working with DESI data or code, importing desispec/redrock/fiberassign, setting $SPECPROD, reading DESI catalogs or spectra, or asking about DESI survey data products.

How to install, configure, and manage the qmd local search MCP server. Covers Node.js installation, npm install of @tobilu/qmd, registering with claude mcp add, adding and re-indexing collections with qmd collection add / qmd update / qmd embed, and diagnosing MCP server registration issues. Use this skill whenever setting up qmd on a new machine, adding a new qmd collection, re-indexing after file changes, or debugging why qmd tools are not appearing in a session.
