Tool-Call Approval Queue

An AI agent proposes actions (sending an email, deleting a branch, opening a ticket), and nothing runs until a person approves it. The approval queue is where they do that, many times a day, so it has to feel instant and must never lose a decision silently.

Build the approval queue.

Requirements

• On load, fetch GET /api/tool-calls, which answers { "calls": [{ "id", "tool", "summary", "risk" }] }. While it loads, show Loading tool calls....
• Show a heading Pending tool calls (N), where N is the number of calls in the queue, and a list with one item per call showing its tool, its summary and, when risk is "high", a High risk badge. Each item has an Approve and a Reject button.
• Optimistic decisions: clicking Approve or Reject removes the call from the list immediately (and updates N), then sends POST /api/tool-calls/<id>/approve or POST /api/tool-calls/<id>/reject.
• If that request fails, put the call back where it was in the original list and show an alert: Could not approve "<summary>". It is back in the queue. (or Could not reject ...).
• Approving a high-risk call first asks with confirm(), with the call's summary in the message. If the user cancels, nothing changes and nothing is sent. Rejecting never asks, and neither does approving a low-risk call.
• When the queue is empty, show No tool calls waiting for approval.
