Short answer
Test Muse with one low-value, reversible purchase from a trusted merchant. Set a hard total, approved merchant and item, quantity, delivery address, deadline, substitution rule, and requirement for final approval showing the complete price and cancellation terms. Never start with travel, medicine, financial products, subscriptions, resale goods, or anything time-critical.

Define bounded authority
State the maximum item price, taxes, fees, shipping, tip, currency, seller, condition, warranty, renewal, and permitted substitutions. “Find me the best deal” can conflict with delivery, returns, privacy, or seller quality. Specify which tradeoffs Muse may make and which require a new approval.
Make approval meaningful
The approval screen should name the merchant, exact item, variant, quantity, total, recurrence, delivery, refund window, and any changed assumption. Reject vague approvals such as “continue” after a long task. A person should not need to reconstruct the transaction from prior chat.
Test failure and duplication
Create an expired coupon, inventory change, price increase, duplicate click, interrupted checkout, declined payment, suspicious merchant, and prompt injection on a product page. Verify that Muse pauses rather than improvising, and that retries cannot create two orders.
Exercise reversal
Capture the receipt, order number, merchant terms, transcript or action history, and approval record. Cancel the test purchase, request a refund where appropriate, and verify the money, order state, and connected payment authority. Record who handles a dispute when agent intent and merchant evidence differ.
Expand only from evidence
Track approved savings, review time, wrong-item rate, duplicate rate, unexpected fees, refund time, and failures caught by approvals. A successful cheap purchase justifies another bounded trial—not permanent open-ended spending authority.

Frequently asked questions
What should the first Muse purchase be?
A low-value, reversible item from a trusted merchant with no subscription, resale, medical, financial, or time-critical consequence.
What belongs in the final approval?
Merchant, item, variant, quantity, full total, recurrence, delivery, return terms, and every changed assumption.
How do I prevent duplicate purchases?
Use an idempotent order check where possible, prohibit automatic retry after uncertain checkout, and require order-status verification before another attempt.
Should Muse have a permanent spending limit?
Prefer per-transaction approval and narrow merchant or task limits. A standing cap still permits repeated unwanted transactions up to that amount.
