bridle
An AI agent that can spend money needs a limit that is enforced, not advertised. bridle is that limit: a per-agent budget that reserves funds before the payment happens and refuses when the reservation cannot be made.
The problem it solves
- A budget checked after the fact is not a budget. By the time the total is over, the money is gone.
- An agent in a retry loop can spend the same allowance many times if nothing reserves it first.
- When the guardrail is unavailable, most systems fail open, which is precisely backwards for money.
What it does
- Reserves before paying, so the limit is checked while the money can still be stopped.
- Fails closed: if the reservation cannot be made, the payment does not happen.
- Keeps the budget per agent, so one misbehaving agent cannot spend another's allowance.
- Leaves an auditable record of reservations and releases.
What it is, technically
A TypeScript package on npm as @igarzatech/bridle, backed by Postgres, released under Apache-2.0. The source is public, which is the only way a claim like this one can be checked.

Questions we get asked
Why open source?
Because a guardrail you cannot inspect is a guardrail you have to take on faith. Publishing the source is the difference between a claim and a verifiable one.
Does it move money itself?
No. It decides whether a payment is allowed and holds the reservation. Moving the money stays with whatever payment system you already use.
Can I use it without hiring you?
Yes. Apache-2.0 means exactly that. We would rather it be used than be a lead magnet.
Building agents that spend?
Read the source first, it is short. If you want help wiring it into something real, that is a conversation we are glad to have.
