FAQ

Do these agent finance tools send data to a server?

No. The calculators and generator run in the browser with plain client-side JavaScript. They do not submit inputs to a backend.

Are the outputs financial advice?

No. They are planning aids for builders and finance operators. Treat the numbers and policies as drafts to review against your own accounting, legal, security, and risk requirements.

Which tool should I start with?

Start with the Agent Budget Calculator to estimate exposure, then use the Spend Policy Generator to turn that exposure into explicit caps and approval thresholds.
