browser-profile skillA

browser-profile is agent-read markdown (skill) from vanducng/skills: Manage named persistent browser profiles (cookies, localStorage, IndexedDB, cache) that both you and Claude can use against the SAME Chrome window without collisions. Each profile lives in its own `--user-data-dir` and exposes a deterministic `--remote-debugging-port`. Use when the user says "open profile X", "attach to profile X", "log me into staging once and reuse it", or asks to test frontend flows with persistent auth across runs. Pairs with the `agent-browser` CLI (`agent-browser connect <.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add vanducng/skills/browser-profile@v0.1.0
Exact content
mdr add vanducng/skills/browser-profile@sha256:86acdb3642a01048

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
