 "title": "Let your coding agent read and edit design screens",
 "page_title": "How to let your coding agent read and edit design screens with Quilt",
 "summary": "Connect Claude Code to Quilt over MCP so it can inspect and patch screens without losing others' edits.",
 "who": "A developer using a coding agent who wants the agent to revise existing design screens directly instead of copying HTML by hand.",
 "problem": "Copying screen HTML between a design tool and an agent is slow, and two writers can overwrite each other's changes.",
 "outcome": "The agent reads a compact outline, edits one part of a screen, and writes a new revision that is safe against stale bases.",
 "steps": [
  "Start Quilt with `node apps/cli/bin/quilt.js` and keep it running.",
  "Connect the agent with `claude mcp add --transport http quilt http://127.0.0.1:3100/mcp`.",
  "Ask the agent to call `get_outline` first, then `get_screen` for the screen it needs.",
  "Have the agent change part of a screen with `patch_screen`, passing the current revision ID as expectedRevisionId.",
  "Open the canvas and check the new revision in the revision tree, then roll back with `restore_revision` if needed."
 ],
 "agent_prompt": "Using the quilt MCP server at http://127.0.0.1:3100/mcp, call get_outline, then get_screen for the screen named <screen-name>, and use patch_screen to change <change-description>. Report the new revision ID. Verify the write succeeded and that a stale expectedRevisionId returns a 409 response.",
