What it helps with
- Look up registered entities in the SAM.gov database
- Verify vendor status against federal exclusion lists
- Retrieve active contracting opportunities and award notices
- Inspect federal agency hierarchy and subaward records
Example prompts for the agent

- Retrieve details on recent federal awards and subawards
