When you buy something yourself, you know why you bought it. When an agent buys something for you, that context is invisible unless the system is designed to capture it.
Axiom logs the complete reasoning chain for every purchase. Not just the amount and merchant, but the agent's thought process: what it was asked to do, what options it considered, why it chose a specific item, and how it verified the purchase was within your rules.
This matters for three reasons.
Trust
If your agent books a $187 flight, you want to know it checked three options and picked the cheapest one within your travel budget. The audit trail shows you exactly that: not just the charge, but the reasoning behind it.
Debugging
Sometimes agents make mistakes. Maybe it ordered the wrong size, or chose a more expensive option when a cheaper one was available. The reasoning log lets you trace exactly where the decision went wrong, so you can adjust your rules or the agent's instructions.
Compliance
If you're using Axiom for business expenses, you need a paper trail. Every Axiom receipt includes the timestamp, merchant, amount, card number used, spending rule that authorized it, and the full agent reasoning. It's more detail than most human expense reports.
We think of the audit trail as the contract between you and your agent. The agent acts on your behalf, and in return, it shows its work. Every time.
