Then give it the first task

Start from your idea or improve a project you already have. Your agent keeps the facts and shows you the work.

Use Plate to create an original project from my idea, or improve this project’s main page. Keep my real content, prices, language and working features. If this is new, establish a direction and build one representative first version; there is no earlier baseline to compare. If the project already exists, inspect it first. Once a real page is running, capture the current page at desktop and phone widths, explain the weakest part, improve it, then capture it again at the same sizes. Test the main action and report what still needs work.

What you should see

• Your agent lists the Plate tools it actually connected to — not a promise that it did.
• A capture of your own running page at desktop and phone width.
• A before and after pair you can look at, and a plain account of what is still weak.

Copying a prompt is not proof that Plate is installed. The tool list and the captures are.

If something goes wrong

• Nothing was copied. The prompt above is selectable — select it and press Ctrl+C (Cmd+C on a Mac). Some browsers block the clipboard on an unfocused tab.
• No Python, or the wrong one. Plate needs Python 3.11 or newer. Install it, then tell your agent to use that exact interpreter for both the install and MCP.
• Capture reports a missing browser. Run python -m playwright install chromium in the same environment Plate was installed into.
• The tools do not appear. Most clients only read MCP configuration at startup. Restart Claude Code, Codex or Cursor and ask again for the real tool list.
• Still stuck. The full manual steps are in the setup documentation.
