Sources

A property agent’s sources control what data it can see before it produces a value.

Source	What it includes
Record context	The record’s own fields, including a snippet of each directly linked record.
Workspace pages	Documents the agent has access to through its scope.
Web	Public web search.

Defaults per kind

The four kinds preselect sensible defaults. You can always override them.

Shorter, more focused context: cheaper, faster, and less likely to drift.
Privacy: agents that don’t need web access shouldn’t have it.
Reproducibility: a record-only agent tends to give the same answer twice in a row; a web-enabled agent doesn’t.
