# Guides

> End-to-end walkthroughs that string the Catalyst platform together into a single workflow.

Guides are end-to-end walkthroughs. Where the rest of the docs explain one feature at a time, a guide takes you from an empty project to a finished outcome, stitching tracing, metrics, Halo, and your coding agent into one continuous loop.

## Start here

<CardGroup cols={1}>
  <Card title="Optimize an agent end to end" icon="arrows-rotate" href="/guides/optimize-an-agent-end-to-end">
    Install tracing, record real traces, read the metrics, run Halo to find what to fix, then apply the fixes by hand or by pulling them straight into your coding agent. The full Halo loop, start to finish.
  </Card>

  <Card title="Measure your agent's quality with Signals" icon="signal-stream" href="/guides/measure-agent-quality">
    Turn raw traces into metrics. Define plain-language classifiers — frustration, sentiment, task outcome — and let an LLM judge label every span automatically, then filter and chart your traces by them.
  </Card>
</CardGroup>

## What you need

Every guide assumes you have:

* A free [Inference account](https://inference.net/register).
* An app or agent that makes LLM calls (any provider or framework).
* A terminal with Node.js or Python, depending on your stack.

More guides are on the way. If there's a workflow you want walked through end to end, [let us know](mailto:support@inference.net).
