How it works

Teach it once

Tell an AI how you work. It turns your process into a SKILL.md; ExpertOS checks the file before a person reviews it for listing.

Find the right method

Describe the task. ExpertOS returns only relevant reviewed Skills, with price, source, and risk information up front.

Pay only when used

For paid APIs, an x402-ready Agent sees the price, applies its budget rules, pays in USDC, and receives the result plus a payment record.

Check before you trust

Review lowers obvious risk; it is not a safety guarantee. Check permissions, keep secrets out of prompts, and require confirmation before payments, publishing, deletion, or other important actions.
