Browser Trace

Browser Trace gives an agent a structured record of what happened during a browser automation run. It observes an existing Chrome DevTools Protocol session, preserving technical events and visual state so failures can be examined after the run or while another client continues operating the browser.

Highlights

• Records network, console, runtime, log, navigation, and optional DOM activity.
• Captures screenshots and HTML snapshots at regular intervals for visual comparison.
• Separates large event streams into searchable files grouped by page and protocol domain.
• Supports local Chrome targets and remote Browserbase sessions, including attachment to active runs.
• Includes helper scripts for starting, stopping, processing, finalizing, and querying captures.

This skill is useful for automation engineers, agent developers, and QA teams investigating missing elements, failed requests, JavaScript errors, stalled navigation, or inconsistent browser behavior. It requires Node.js 18 or newer and the browse CLI; jq is optional for custom queries, while remote sessions require Browserbase credentials. Install it from the Browserbase skills repository with the published skills command.
