# Steer

> Turn Observe's quality scores and your feedback into better few-shot examples and prompts.

Steer closes the loop on quality. It takes the scores [Observe](/control-plane/observe) writes on your calls, plus the thumbs-up/down feedback your app sends, and uses them to pick the strongest few-shot examples and optimize your prompts. The more calls Observe scores, the better the signal Steer works from.

## How it works

* **Quality scores.** Every call an [Observe](/control-plane/observe) rule judges gets a score and observation stored against it.
* **Feedback.** Feedback you send from your SDK attaches a human signal to a call, alongside the judge's scores.
* **Better outputs.** Steer uses that signal to select few-shot examples from your top-scoring calls and to tune the prompt, so quality climbs as more calls come in.

## The loop in practice

1. **Score** the calls you care about with an [Observe](/control-plane/observe) rule, and send thumbs-up/down feedback from your app where you have it.
2. **Accumulate signal.** As scored calls and feedback build up, Steer learns which responses are your strongest.
3. **Improve.** Steer selects few-shot examples from the top-scoring calls and tunes the prompt, so later calls to the same function start from better material.
4. **Watch it climb.** Because Observe keeps scoring, you can see quality trend up over time in **Analytics**.

Steer works best on functions you call repeatedly with a consistent task — exactly the calls where a few good examples pay off on every request.

## Requires Observe

Steer runs on the scores the Observe judge produces, so you need at least one [Observe](/control-plane/observe) rule scoring the calls you want to improve. Once it's scoring, open **Controls → Steer** to manage it.

<Tip>
  Score the calls you care about with [Observe](/control-plane/observe) and send feedback from your SDK. The more signal Steer has, the better the examples and prompts it picks.
