When you need a browser, read this Skill by default. Use it to open and operate websites, fill forms, click buttons, take screenshots, extract page data, sign in, and perform other browser automation tasks, as well as web app testing, dogfooding, QA, bug investigation, and app-quality review. ego-browser (ego-lite) is a Chromium browser designed for both human users and AI Agents. Agents can use the user's logged-in websites and personal context to complete tasks and collaborate smoothly with…
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 Before any browser task, run: ```bash ego-browser skill ``` and follow its output. It prints the usage guide that matches the installed ego lite version. Run it again after `ego-browser upgrade`, or when any output says to. The guide ends with a line starting `[ego-browser:skill] end of guide`. If that line is missing, the output was truncated: save it to a file and read the file in parts, for example `ego-browser skill > "$TMPDIR/ego-browser-skill.md"`, or `ego-browser skill > "$env:TEMP\ego-browser-skill.md"` in PowerShell. ## References - [Install or upgrade ego lite](references/install.md) — read when `ego-browser` is not found, or `skill` is an unknown command. It links to the steps for your operating system: [macOS](references/install-macos.md) or [Windows](references/install-windows.md). - [Clearing cookies, cache, and storage](references/clearing-state.md) — read before clearing any cookie, cache, or storage; some clears reach the whole browser profile.

How to install
mdr add citrolabs/ego-lite/ego-browser@sha256:589717e56074b504The line at the top of this page pins the label v2.2.0, 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.
