## When it is useful

Install or update DuckDB extensions (INSTALL / name@repo). Not first-time CLI or brew install of DuckDB itself. False-fires on first-time CLI setup. Local OSS 0 USD, no cloud, no key.

## The Catch

INSTALL extension NOT brew-installing DuckDB. False-fires on first-time CLI setup. Local OSS 0 USD, no cloud, no key. Distinct from Neon/PlanetScale SQL.
