# Sources

> What data the agent reads before writing a value.

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.

* Summarize, record only.
* Research, record + web.
* Classify, record only.
* Prompt, record only.

## Why limit sources

* 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.
