browser-trace skillB

browser-trace is agent-read markdown (skill) from vanducng/skills: Capture a full DevTools-protocol trace of a locally driven 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 local session, or feed structured per-page summaries back into an agent loop so its next iteration learns from the last one..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add vanducng/skills/browser-trace@git:20260911.9e58ef3
Exact content
mdr add vanducng/skills/browser-trace@sha256:b669b1d81f80d836

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
