Using it with your coding agent
Hand the Rebuild Package to Claude Code, Cursor or Codex.
The Rebuild Package and the agent prompt are built to work together. The package holds the evidence; the prompt tells your agent how to use it.
The workflow
- Export the Rebuild Package from the capture's Export menu.
- Unzip it into your project root, or open the folder on its own.
- Open the project in your coding agent. Claude Code, Cursor, Codex or another agent that can read project files.
- Paste the agent prompt. Use Copy agent prompt in the Export menu, or paste the contents of
AGENT_PROMPT.md. - Let the agent run the self-validation loop in
REBUILD.mdsection 9.
Expect a strong first pass, then iterate on the known gaps.
What the agent prompt tells your agent
- Read
REBUILD.mdfirst. - Treat
screenshots/as ground truth. - Use the files in
assets/directly instead of recreating them. - When anything is ambiguous,
evidence.jsonwins. - Ask you about anything marked inferred or listed under Unknowns, instead of guessing.
- Finish the self-validation loop in
REBUILD.mdsection 9 before calling the build done.
Working with DESIGN.md only
For a site you don't own, use DESIGN.md instead of the Rebuild Package:
- Export
DESIGN.mdfrom the Export menu. - Put it in your repository root.
- Tell your agent once: "All UI work follows DESIGN.md. Colors, type, spacing and motion come from it, not from your defaults."
Tips
- Answer the agent's questions about known gaps. Mateo captures evidence, not a guarantee. Your agent closes the last gap with you.
- Low coverage means the build leans more on screenshots and iteration. Plan for an extra round. See Coverage and known gaps.
