browser skillB

browser is agent-read markdown (skill) from bug-ops/zeph: Browser automation via Playwright MCP — navigate pages, click elements, fill forms, take screenshots, extract text, manage tabs, and run JavaScript in the browser. Use when the user asks to open a website, interact with a web page, scrape dynamic content, fill out forms, take a page screenshot, test a web application, or automate browser workflows. Requires a Playwright MCP server configured in [[mcp.servers]]..

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 bug-ops/zeph/browser@v1.0
Exact content
mdr add bug-ops/zeph/browser@sha256:72ee685622fbc9a4

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.
