# Trust is earned on your own history

Safety / August 23, 2026 / Krishna Bhatnagar

Before a job runs without your agent, it has to get your past conversations right. Why we start from history, and what stays protected.

Handing work away from a model raises a fair question: how do you know the job will be done right?

Our answer is your own history. A job goes live only after it gets your past conversations right, and you see how each job did before it goes live. Nothing is assumed because it worked somewhere else.

> Nothing goes live until you've seen how each job did on your history.

## What stays protected

- Your agent is always the fallback. Anything new, unclear or unusual goes to it, unchanged.
- Nothing irreversible happens without your customer's explicit yes. A compiled job asks before it changes anything.
- It fails open. If AgentCompile has any problem, or a step takes too long, the call goes straight to your model.
- Your provider key never reaches AgentCompile.

## Watch before it acts

You don't have to hand anything over to start. With mode set to shadow, AgentCompile decides what it would do while your model keeps answering everything, and every call is logged on your machine, so you can read the decisions yourself.

## What the replay showed

On 478 recorded agent conversations it never learned from, AgentCompile did exactly what the agent did in 430, left the other 48 to the agent, and never did anything different.

## Why history, and not a test suite

A test suite checks what someone thought to write down. Your history is what actually happened: the real requests, the real edge cases, the real way your customers ask for things. A job that gets your past conversations right has been checked against the work it will actually see.

## The order of trust

1. Watch. With mode set to shadow, AgentCompile decides what it would do and your model keeps answering everything.
2. Read. Every call is logged on your machine, and agentcompile trail shows where each one went.
3. Review. You see how each job did on your history before it goes live.
4. Run. Known jobs run compiled. Anything new, unclear or unusual still goes to your agent, unchanged.

## Questions we get

**What happens if AgentCompile is down?** The call goes straight to your model. It fails open, so the worst case is the way your agent runs today.

**Does my provider key reach AgentCompile?** No, never. Your agent's model is called with your own key, from your side.

**What data leaves my machine?** Without capture, the request needed to decide, used in memory. With capture, each call, scrubbed on your machine before it's sent.
