Omit id; the platform returns an opaque fld_…. config is type-specific; keys for another type fail validation. Read fields.types for config shapes. Computed fields (lookup, rollup, formula, button) have no column and are derived at read time. A link creates its mirror on the other table in the same write; both are deleted together.

Requires the schema:write scope. Operation fields.create. MCP tool fields_create. CLI: grid82 fields create (npx grid82).
