Attaches a second, read-only CDP client to any running browser automation so you can debug failures or audit what actually happened without restarting. Records the full DevTools firehose to NDJSON, polls for screenshots and DOM snapshots in parallel, then bisects everything into per-page buckets you can grep and search. Works with local Chrome or remote Browserbase sessions, and because it only listens it won't interfere with your main automation. Especially useful when you need to see what went wrong in a failed form submission, hunt down a missing element, or feed structured summaries back into an agent loop so the next iteration learns from the last one.
