Capture a full DevTools-protocol trace of any browser automation — CDP firehose, screenshots, and DOM dumps — then bisect the stream into per-page searchable buckets. Use when the user wants to debug a failed run, audit network/console/DOM activity, attach a trace to an in-progress session, or feed structured per-page summaries back into an agent loop so its next iteration learns from the last one.

# Browser Trace

Attach a **second, read-only CDP client** to a browser session that is already being driven by your main automation. The trace records the full DevTools firehose to NDJSON, polls for screenshots and DOM dumps in parallel, and slices everything into a directory tree that bash tools can search.

This skill does **not** drive pages — it only listens. Pair it with the `browser` skill, `browse`, Stagehand, Playwright, or anything else that speaks CDP.

## When to use

- The user wants to debug a browser-automation run (failing form, missing element, hung navigation, JS exception).
- The user has a running automation and wants to attach a trace mid-flight without restarting it.
- The user wants to split a CDP firehose into network / console / DOM / page buckets.
- The user wants screenshots + DOM snapshots over time, joined to CDP events by timestamp.

If the user just wants to **drive** the browser, use the `browser` skill instead.
