Typed columns. Editable grid. Agents read and write rows directly. No external Postgres. No spreadsheet exports. The state your agents share lives where they live.
Real types. Real validation. File references resolve through the same Files store any agent uses.
Agents query, append, update rows through workspace tools. No bring-your-own-API.
"Run this workflow for every row in customers" is a first-class pattern, not a hack.
