Model API Inspector

Every provider round-trip is rendered as an inline panel in the chat:

• Collapsed: one dense line — API provider/model status latency ↑tokens ↓tokens ⚡cache% $cost time
• Expanded (Ctrl+O on the panel): HTTP method + URL, status, latency, request ID, stop reason, notable headers (rate limits, retry hints), then raw request/response JSON

The inspector resets each turn so you only see calls for the current prompt. Steering/follow-up messages during streaming also reset the panel.

Configuration

Edit CONFIG at the top of model-api-inspector.ts:

| Option | Default | Description | |--------|---------|-------------| | maxCalls | 5 | Most recent calls to show (Infinity = all) | | maxStringLen | 50 | Truncate strings in raw JSON | | showRaw | true | Show request/response JSON in expanded view | | hidePaths | ["tools"] | JSON paths to collapse to a placeholder | | headerFilter | /ratelimit\|rate-limit\|retry-after\|request-id/i | Response headers to surface |
