Use when automating a real, logged-in Chrome WITHOUT disturbing the user's open tabs — e.g. authenticated sessions like ChatGPT, LinkedIn, or any site needing a persistent login. Launches or reuses a dedicated debug Chrome instance per named profile that coexists with the user's main browser; it never quits or kills any browser (unlike real-browser, which closes Chrome Beta's tabs). Trigger on "automate this site without closing my tabs", "use my logged-in session…
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
# browser-mate Non-destructive Chrome automation. The problem it solves: to attach a CDP/`agent-browser` session, Chrome must run with `--remote-debugging-port`. The `real-browser` skill achieves this by **quitting Chrome Beta first**, destroying the user's open tabs. `browser-mate` instead runs a **dedicated debug Chrome instance** (its own `--user-data-dir` + port) that **coexists** with the user's main browser — Chrome permits concurrent instances when the data dirs differ, so no quit is needed. ## The one invariant (never violate) **Never quit, `pkill`, or `osascript quit` any browser.** The skill only ever launches a new dedicated instance or reuses an existing one. The single `stop` path sends SIGTERM only to a process matched by BOTH our dedicated `user_data_dir` AND our debug port — never the user's browser. ## Usage ```bash # Ensure a profile's debug Chrome is up (launch or reuse); prints the PORT on stdout PORT=$(python3 scripts/browser.py chatgpt) # Then drive it with agent-browser (always pass --cdp $PORT). See references/agent-browser.md SID=$(LC_ALL=C tr -dc 'a-z0-9' < /dev/urandom | head -c 6) …

How to install
mdr add glebis/claude-skills/browser-mate@sha256:a20d8286ab972049The line at the top of this page pins the label git:20260603.90dabb0, 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.
