Probe Page
probe_pageProbe one or more URLs to capture rendered screenshots, page metadata, console errors, and network summaries. Verify changes without breaking your app—fast batch mode for up to 20 URLs.
Instructions
Probe one or more URLs and return their rendered state — screenshot, page metadata (title/finalUrl/statusCode/loadTimeMs), structured console errors, and per-URL network summary (refetch loops collapse into one row by origin+pathname).
WHEN TO USE: "did I just break /settings?" / "smoke-test these 5 routes after my refactor" / "what's actually rendering at /dashboard?" — fast (<10s for 1 URL, <25s for 20), no LLM cost, no agent loop.
NOT FOR: scenario verification (sign in → click X → assert Y), interaction (clicks, form fills, scrolls), or anything requiring agent decisions. Use check_app_in_browser for those.
LOCALHOST SUPPORT: any localhost URL is auto-tunneled. Pre-flight TCP probe fails fast (<2s) if the dev server isn't listening.
BATCH MODE: pass up to 20 targets in one call to share browser session + tunnel — dramatically faster than firing parallel single-URL probes (one execution unit, not N). Per-URL waitForSelector / waitForLoadState / timeoutMs override defaults.
A single failed target's error appears in result.error without failing the whole batch — the other results stay valid.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| targets | Yes | 1-20 URLs to probe. Each entry can carry its own per-URL wait config. | |
| repoName | No | GitHub repository name (e.g. 'my-org/my-repo'). Auto-detected from the current git repo — only provide this to scope the probe to a different project context. | |
| includeHtml | No | If true, each result includes the page's outerHTML. Default false to keep response size sane. | |
| captureScreenshots | No | If true (default), one PNG screenshot is returned per target. Set false for very large batches or when only the structured data matters. |
