browser-preview skillC
browser-preview is agent-read markdown (skill) from starchild-ai-agent/official-skills: Preview panel and iframe diagnostics: registry, ports, paths, blank screens. Use when a preview tab is broken or missing (e.g. white screen, tab disappeared, 404 on assets, preview not loading, list running services)..
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
mdr add starchild-ai-agent/official-skills/browser-preview@v1.1.2mdr add starchild-ai-agent/official-skills/browser-preview@sha256:a4d3bbfbcc460c23Pin 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.
