dev-browser
Skill2 starsChanged 3 months agoMITView on GitHub
Sandboxed throwaway-Chromium scripting via the upstream `dev-browser` CLI. Use ONLY for unauthenticated QA in a clean browser profile. For anything touching the user's real Chrome — the active tab, signed-in pages, filling forms, clicking, screenshotting "this page" — use the `browser-hand` skill instead.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
1 rule. 0 are common, 0 are distinctive, and 1 is very specific to this project.
0
Common
Most of the 12 edited versions we read keep these.
0
Distinctive
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.

“Common” is measured: kept by at least 6 in 10 of the 12 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Dev Browser (upstream headless line)
A CLI for controlling a sandboxed, throwaway browser with JavaScript scripts.
This is not the skill for driving the user's own browser. Browser Hand's
extension relay does that — it keeps the user's session and cookies and does not
trigger Chrome's WebDriver banner. Reach for browser-hand first, and drop to
this only when a clean, unauthenticated profile is specifically what you want.
Installation
npm install -g dev-browser
dev-browser installUsage
Run dev-browser --help to learn more.
Named daemon-launched browsers persist by default. For unattended work, --idle-timeout 5m closes each launched browser after inactivity while preserving its profile and login state. The setting never closes Chrome attached with --connect; use --idle-timeout 0 to disable configured cleanup.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
