# Custom Instructions & Profile

> Set your name, occupation, background, and permanent instructions the agent follows in every conversation.

Personalization lets you configure how the agent addresses you and what it knows about you before every conversation. Your profile and custom instructions are injected into every agent session automatically.

## Profile fields

Go to **Settings** and fill in these fields:

| Field                   | Max length       | What it does                                                          |
| ----------------------- | ---------------- | --------------------------------------------------------------------- |
| **Nickname**            | 100 characters   | How the agent addresses you.                                          |
| **Occupation**          | 200 characters   | Your professional role. Gives the agent context for better responses. |
| **About Me**            | 2,000 characters | Background information about you, your company, or your projects.     |
| **Custom Instructions** | 3,000 characters | System-level directives the agent always follows.                     |

## Custom instructions

Custom instructions are the most powerful personalization feature. They are injected as system-level directives in every agent conversation. Use them to set rules the agent should always follow.

<Prompt description="Example custom instructions.">
  Always write code in TypeScript. Use Tailwind for styling. When building websites, use Supabase for the database instead of the default. Never use semicolons in JavaScript. Keep all responses concise and skip explanations unless I ask for them.
</Prompt>

<Prompt description="Brand-focused instructions.">
  My company is Dune. Brand colors are #1a1a2e (primary) and #e94560 (accent). Font is Inter. All marketing materials should use a professional but approachable tone. Never use stock photo language.
</Prompt>

## What you cannot do

* You cannot set different instructions for different artifact types. Custom instructions apply globally.
* You cannot set per-conversation instructions. They apply to every conversation.
* You cannot use custom instructions to override system safety guidelines.
* You cannot exceed the character limits for any field.
