# Configure the Core Agent

> Adjust how your Core Agent behaves — its instructions, model, tools, and knowledge.

## Why configure it?

The Core Agent works great out of the box. But you can **tune how it behaves** so it fits your workspace — its tone, its rules, which tools it may use, and what documents it can read.

## Opening the settings

<Steps>
  <Step title="Go to the Agents tab">
    Click **Agents** in the left menu.
  </Step>

  <Step title="Click the settings (gear) button">
    It's at the top of the session list, near the search icon. This opens the agent's configuration.

## The settings, one by one

<AccordionGroup>
  <Accordion title="Instructions — how it should behave" icon="pen">
    Describe, in plain words, how the agent should act — its tone and any rules. Example: *"Always answer in a friendly, concise way. Use our company's product names. Never share internal pricing."* Think of it as the agent's standing orders.
  </Accordion>

  <Accordion title="Model — its brain" icon="brain">
    Choose which AI powers the agent. Faster models for everyday work, smarter models for harder tasks. See [Choosing a model](/user-guide/choosing-models). The default is a solid choice.
  </Accordion>

  <Accordion title="Tools — what it's allowed to do" icon="screwdriver-wrench">
    Turn on the abilities the agent may use — like search or a connected service. Many tools come from your [integrations](/user-guide/integrations). Give it only what it needs.
  </Accordion>

  <Accordion title="Knowledge — what it can read" icon="book">
    Add documents so the agent answers from **your** information — policies, product docs, notes. See [Ask your own documents](/user-guide/knowledge).
  </Accordion>
</AccordionGroup>

<Warning>
  **Give the agent only the tools it needs.** More tools is not better — it can slow the agent down or confuse it. Add one, test, then add another if needed.
</Warning>

## Test after every change

After you adjust a setting, open a **new chat** in the Agents tab and try a task. Tweak the instructions until the agent behaves exactly how you want. Small, clear rules work best.

<Tip>
  Changes to the Core Agent apply across your workspace. If several people share the workspace, agree on the instructions together so everyone gets consistent results.
