Generate a clickable HTML approval page for reviewing UI fixes inside terminal-based AI agents.

ApprovalUI

A tiny open-source loop for reviewing UI fixes inside terminal-based AI agents.

Terminal agents are great for code. They are bad at UI feedback, because UI feedback needs eyes, not paragraphs.

ApprovalUI renders a clickable HTML approval page from a simple JSON spec. You open it in a browser, tick approve or reject per item, generate a review, and paste it back into the agent.

Binary signal. Screenshot attached. No drift.

Why

When you iterate on frontend with a terminal agent, the feedback loop is verbal:

“The divider looks weird — can you make it full height?”

The agent reads text, not pixels. You end up describing the same fix five times.

ApprovalUI short-circuits that loop. The agent writes a structured spec of the fixes, you review them visually, and the page gives you a structured text block to paste back.

Works with Claude Code, Codex, Kimi, or any terminal agent that can write JSON and open a browser.

How it works

1. The agent writes a JSON spec describing each UI fix: title, issue number, screenshot, root cause.
2. approvalui turns the spec into a self-contained HTML page.
3. You open the page, review each item, tick Approve or Reject, add comments.
4. Click Generate review to get a structured text block you paste back into the agent.

Quick start

approvalui example/fixes.json example/approval.html
open example/approval.html

Tick approve or reject, add a comment, and click Generate review.

JSON spec format

{
  "title": "Workeros — Fix Approval",
  "instructions": "Tick the ones you approve, click Generate review, paste it back to me.",
  "items": [
    {
      "id": 1218,
      "title": "Brain split-view divider now runs FULL HEIGHT to the bottom",
      "status": "pending",
      "root_cause": "wrapper used min-h-full so Collection height:100% could not resolve",
      "screenshot": "screenshot.svg"
    }
  ]
}

Only id and title are required. root_cause, screenshot, and instructions are optional.
