Browser automation for AI agents. Use when the user needs to navigate websites, read page content, fill forms, click elements, take screenshots, or manage browser pages.
npx skills add vibiumdev/vibium --skill vibe-check
The vibium CLI automates Chrome via the command line. The browser auto-launches on first use (daemon mode keeps it running between commands).
Every browser automation follows this pattern:
vibium go <url>vibium map (get element refs like @e1, @e2)vibium click @e1vibium mapBefore running any commands, resolve the vibium binary path once:
vibium directly (works if globally installed via npm install -g vibium)./clicker/bin/vibium (dev environment, in project root)./node_modules/.bin/vibium (local npm install)Run vibium --help (or the resolved path) to confirm. Use the resolved path for all subsequent commands.
Windows note: Use forward slashes in paths (e.g. ./clicker/bin/vibium.exe) and quote paths containing spaces.
Chain commands with && to run them sequentially. The chain stops on first error:
When to chain: Use && for sequences that should happen back-to-back (navigate → interact → verify). Run commands separately when you need to inspect output between steps.
When NOT to chain: Don't chain commands that depend on parsing the previous output (e.g. reading map output to decide what to click). Run those separately so you can analyze the result first.

browsers). By default video is recorded when the engine supports it and
skipped otherwise — the stop result says which. Pass --video to require
it (fails with an explanatory error on Chrome), --video=false to disable,
and --video-size 1280x720 / --video-fps 30 to override the viewport
defaults. The video lands inside the recording ZIP next to the trace
(video/<context>.webm); it films the page that was active at start and
does not follow tab switches. Remote browser connections record every
track except video; --video-remote keep records anyway and leaves the
file on the remote host (the stop output names its path there).

Simple expressions — use single quotes:
Complex scripts — use --stdin with a heredoc:
JSON output — use --json to get machine-readable output:
Important: eval returns the expression result. If your script doesn't return a value, you'll get null. Always make sure the last expression evaluates to the data you want.
All interaction commands (click, fill, type, etc.) auto-wait for the target element to be actionable. You usually don't need explicit waits.
Use explicit waits when:
vibium wait url "/dashboard" — after clicking a link that navigatesvibium wait text "Success" — after form submission, wait for confirmationvibium wait ".modal" — wait for a modal to appearvibium wait load — after navigation to a slow pagevibium wait fn "window.appReady === true" — wait for app initializationvibium sleep 2000 — only when no better signal exists (max 30s)All wait commands accept --timeout <ms> (default varies by command).
Refs (@e1, @e2) are invalidated when the page changes. Always re-map after:
| Flag | Description |
|---|---|
--headless | Hide browser window |
--json | Output as JSON |
-v, --verbose | Debug logging |
