How it works
Three passes, in order.
Terminal3 doesn't dump one long answer on you. It moves through Diagnose, Fix and Verify in sequence, because that's the order you actually need them in.
Diagnose
Understand what actually failed.
What it returns
- A plain-English summary of what happened
- One strongest root-cause hypothesis, not a list of equals
- The affected layer
- A confidence score, capped below certainty by design
- Severity
- Signals — exact tokens lifted from your input
- Two or three alternative explanations worth ruling out

Fix
Get an actionable remediation path.
What it returns
- A recommended fix stated up front
- Ordered steps you can follow without re-reading
- Configuration and code guidance in context
- Commands with one-tap copy
- A warning before anything destructive
- A safer alternative where one exists
- Why this should work — the short technical reason

Verify
Confirm the incident is resolved.
What it returns
- A verification checklist you can tick off
- Commands and tests to run
- What a successful response actually looks like
- Regression checks so the fix doesn't break something adjacent
- One monitoring suggestion worth keeping

Limits
What it isn't.
It reads text. That's the whole input.
Terminal3 has no access to your servers, repositories, logs, deployments or monitoring. Everything it concludes comes from the text you paste, which is why it states confidence rather than certainty.
It is not a remote shell.
Terminal3 never executes anything on your infrastructure. Commands are given to you to run, with a warning where they're destructive.
It can be wrong.
A well-known error signature with a clear root cause gets high confidence. An ambiguous log gets a lower one and more alternatives. Read the alternatives — they exist because the first hypothesis sometimes isn't the right one.
Run one yourself in under a minute.
Six sample incidents ship with Terminal3. Each one runs end to end — Diagnose, Fix, Verify — with no setup and no key.
