ego-browser (ego-lite) is a Chromium-based browser designed to be friendly to both human users and AI Agents. AI Agents work in their own isolated space, reusing the user''s login state without competing for the browser. Use this skill whenever the user needs to interact with a website: opening pages, filling forms, clicking buttons, taking screenshots, extracting page data, testing web apps, logging into sites, or automating browser operations. Triggers include "open a website…
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
# ego-browser ego-browser gives AI agents a CLI-accessible Node.js runtime, with built-in helpers - `snapshotText`, `click`, `js`, `cdp`, and more - that agents call directly inside JS scripts to observe pages, interact with UI, evaluate browser-side JavaScript, and drive a real browser. For setup, install, or connection problems, read `references/install.md`. Current ego lite (verified `0.4.7.4`) preloads the **legacy helpers** below. `page`, `browser`, and `taskSpaces` are **undefined**. Do not import Playwright, invent facade names, or treat missing `page.*` as an install failure. If `$HOME/.local/share/ego/ego-skills/SKILL.md` disagrees with this file, follow that app-bundled skill for helper names and signatures, and keep this file's lifecycle, safety, and confirmation policies. Run browser work with the `Bash` tool as `ego-browser nodejs <<'EOF' ... EOF`. Put the JavaScript directly in the heredoc; do not create a `.js` file first. …

How to install
mdr add vanducng/skills/ego-browser@sha256:785ca0f6edd307a3The line at the top of this page pins the label v1.3.3, 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.
