Browse the web using `assistant browser` CLI commands.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Use this skill to browse the web. All browser operations are executed through the `assistant browser` CLI, invoked via `bash` or `host_bash`. Each operation is a subcommand: | Command | Description | | ------------------------------------- | -------------------------------------------------- | | `assistant browser navigate` | Navigate to a URL | | `assistant browser snapshot` | List interactive elements on the current page | | `assistant browser screenshot` | Take a visual screenshot | | `assistant browser click` | Click an element | | `assistant browser type` | Type text into an input | | `assistant browser press-key` | Press a keyboard key | | `assistant browser scroll` | Scroll the page or a specific element | | `assistant browser select-option` | Select an option from a native `<select>` element | …

How to install
mdr add vellum-ai/vellum-assistant/vellum-browser-use@sha256:2ecaa079d54359afThe line at the top of this page pins the label git:20260921.4272b23, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
