# Plan Mode

> How to prompt the agent to plan your project before it starts building.

## Prompt the Agent to Plan First

The agent can build things fast, but it builds what you ask for — so if your first prompt is "build me a dashboard," it'll start building immediately. A better approach is to prompt the agent to **plan first**, so you can align on what gets built before any code is written.

This matters most when you're:

* Starting a new project from scratch
* Adding a major feature with multiple parts
* Working on something you haven't fully figured out yet

## How to Plan with the Agent

Tell the agent what you want to build and explicitly ask it to plan before building. The key phrase is: **"Don't build anything yet."**

Here are some examples:

* "I want to add a booking system to my site. Plan out the full feature — what pages I need, how the user flow should work, and what components to build. Write it all down before you start coding."
* "I'm building a dashboard with user analytics. Break down the structure, list the sections, and outline what data each section shows. Don't build anything yet."
* "Plan a checkout flow for my store. Think through each step the user goes through, what happens on each page, and how errors should be handled."

The more context you give — your goals, preferences, pages you already have, features you want — the better the plan will be.

## Use a Higher Tier for Planning

The **High** and **Max** agent tiers are best for planning. They're the most capable agents, so they're ideal for thinking through complex ideas, asking the right questions, and writing a detailed plan.

Once the plan is ready, you can switch to **Low** or **Medium** to actually build it. This way you get top-quality thinking upfront without spending top-tier credits on the entire build.

## Walk Through the Plan Together

Don't just read the plan and say "go." Treat it like a conversation:

1. **Start broad.** Tell the agent the big picture — "I want an online store" or "I need a portfolio site with a blog."
2. **Let the agent break it down.** It will outline the pages, components, and flow.
3. **Correct what doesn't match.** If the agent suggests a three-step checkout but you want a single-page checkout, say so now.
4. **Agree on the order.** Decide what gets built first. Usually it makes sense to go page by page or feature by feature.

Changing a plan is free. Changing built work costs credits.

## Tips

* **Say "write the plan down."** Be explicit about this. When the plan is written in the conversation, the agent can reference it while building — and so can you.
* **Don't worry about technical terms.** Describe things the way you'd explain them to a friend. The agent will translate your ideas into a buildable plan.
* **Review before building.** Read through the plan carefully. If something doesn't match what you had in mind, correct it now — it's much easier to fix a plan than to redo built work.
* **Plan in pieces for big projects.** If your project has multiple major parts, plan and build one part at a time. Planning everything at once can lead to a plan that's too long for the agent to follow precisely.
