Implement changes in Build mode

1. 1

   Make sure you are in Build mode in your project chat.

   This mode allows Lovable to directly modify your project files.

2. 2

   Describe what you want Lovable to do in the chat, being specific about requirements and expected behavior.

   Clear instructions help Lovable understand your intent and produce better results.

3. 3

   Provide context for complex changes or set guardrails for sensitive areas if needed.

   This helps Lovable make informed decisions and avoid unintended modifications.

4. 4

   Send your message and observe Lovable's progress through visible tasks in the chat or the Details view.

   You can follow along, understand what's happening, and stop the process if something seems off.

5. 5

   Send follow-up messages, corrections, or new ideas at any time while Lovable is working.

   Lovable will pick up your input at its next natural stopping point without losing previous work, allowing you to steer the process.

Add a contact form with name, email, and message fields. Validate email format and show error messages inline. Do not modify @src/shared/Layout.tsx or the existing authentication logic.

Build mode

A way of working where Lovable directly changes your project files and checks if those changes work, without you needing to manually approve every step.

File diffs

A comparison that shows exactly what lines of code were added, removed, or changed in a file.

Refactor code

To reorganize and clean up existing code without changing how the program works, making it easier to understand and maintain.

Guardrails

Instructions that tell Lovable what parts of your project it should or should not touch, or specific rules it must follow.

Details view

A special screen that shows you a step-by-step breakdown of everything Lovable is doing, including which tools it's using and which files it's changing.

• Not being specific enough in your prompt can lead to Lovable making changes you didn't intend or exploring too much of your codebase, which can increase costs.
• Forgetting to switch to Plan mode for complex or unfamiliar changes means you might spend more credits on implementation before you've fully thought through the approach.
• Not monitoring Lovable's progress in the chat or Details view means you might miss an issue or an expanding task, potentially leading to unwanted changes or higher costs.
• Ignoring credit check-ins can lead to unexpectedly high costs for long-running tasks if you don't stop them when prompted.
• Not using the stop button when Lovable is going in the wrong direction can result in wasted credits and unnecessary changes.
