Drive one persistent, logged-in browser from the shell with `co browser`. Use when the user asks to open a page, log into a site, scrape/extract page content, fill forms, upload files, take screenshots, or automate any browser task — solo or with multiple agents sharing the browser.
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
# co browser Skill Drive **one real browser** from the shell. The browser stays open between commands — cookies and logins persist until `co browser close`. Every terminal on the machine talks to the same daemon: one browser, one board, no matter where you type. **Read the output as well as the exit code.** A selector that matched nothing exits `1` and no browser open exits `3`, so `co browser ... && next_step` stops where it should — but a click that landed on the wrong element still exits `0`, and only the page (a screenshot, `get_text`) can tell you that. ## Step 1: Identity — who are you? The daemon attributes every tab to a caller and uses that identity to stop two agents from silently driving the same page. **Set `CO_WHO` explicitly** — shell state does not survive between your tool calls, so a lone `export` is lost. Either prefix every command: ```bash CO_WHO=alice co browser go_to example.com ``` or keep the export and the commands in the SAME shell invocation: ```bash export CO_WHO=alice && co browser go_to example.com && co browser get_text ``` (Some environments — e.g. Claude Code background jobs — are auto-identified, …

How to install
mdr add openonion/connectonion/co-browser@sha256:5794096eebda2297The line at the top of this page pins the label git:20260927.19ada76, 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.
