Your agent builds a prototype. Your team reviews and comments on it. Your agent rebuilds it — and every comment anchor survives the regeneration. Any model, no lock-in.
Last step before payment — keep it scannable so the total never feels like a surprise.
Main risk is drop-off when cost feels unclear, so checkout should read as the obvious next step. Sara wants an editable quantity stepper per item — agree, let's try it.
Your agent renders each screen over MCP and tags every element with a stable anchor ID.
Reviewers pin feedback to a specific element — not a vague "make the button better."
Your agent reads the unresolved comments, rewrites the page, and every comment stays put.
Stable IDs survive full DOM regeneration. When an element moves, a semantic fallback re-resolves it. Threads travel across versions.
Claude Code, Codex, Cursor — any MCP client drives the loop. No vendor lock-in, no per-seat model pricing.
Immutable snapshots you can diff, restore, and track in your own repo. No cloud lock-in.
