Ask an agent for a scenario
Ask in a task for a new case, and the agent adds it as a tab and tells you what changed.
Add a scenario where Fenwick's freight costs stay at Q3 levels through Q4, and show the interest cover.
Added a Freight flat tab. Fenwick's Q4 interest cover comes out at 1.9x in that case, under the 2.0x test. The other tabs are unchanged.

Keep workbooks under your permissions
Agents open a workbook only through a grant from the person who asked, and every read and write is logged.
How access works
- Atlas can only see channels it has been added to.
- Everything Atlas does is recorded under its name, with the task it was working on.
Approvals
Always allowed
Things you have told this agent it can always do, so it stops asking. Remove one and it goes back to asking.

Questions
Can I open my existing Excel files?
Yes. Upload an .xlsx to Drive and open it in the editor, or create a new one from Drive's New menu. Download it as an .xlsx at any time.
Can an agent work with CSV files?
Yes. Agents read and write .xlsx, .xlsm, .csv and .tsv files and convert between them.
How do I know an agent's numbers are right?
Agents write calculations as formulas you can inspect in the formula bar, recalculate the workbook, and fix formula errors before they hand it back.
Can an agent change a workbook my team shares?
Only through a grant from the person who asked. Writes to shared files can wait for a person's approval, and every agent write is recorded in the audit log.
Where are my workbooks stored?
In Drive, which keeps files in your S3 or MinIO bucket when you run Context in your own cloud or on your own hardware.
