Browser Skills is a new open directory from Browser Use that gives AI coding agents pre-built, site-specific automation playbooks -- called domain skills -- so they stop wasting time figuring out the same websites over and over again. It launched alongside the browser-harness project and is free to use today.
The tax every browser agent pays
Every browser agent does the same thing: it re-discovers every website from scratch, every time it runs. Open a tab, poke around, find the button, click it, parse the response, close the session. Repeat. Agents burn through tokens re-learning sites they have already conquered, and teams painstakingly hand-write scripts for workflows an agent already solved last week -- the same discovery tax paid over and over, across thousands of sessions.
The browser is still the entry point for many real workflows -- admin panels, SaaS dashboards, ecommerce sites, recruiting platforms, CRMs -- and many of them do not expose stable APIs, or their API permissions are harder to obtain than plain webpage access. Browser Skills is the answer to that gap.
What a "domain skill" actually is
A domain skill is a folder of markdown files that captures everything a browser agent needs to know about a specific site: which selectors to use, which flows to follow, which edge cases to watch for, and when to avoid the browser entirely. When BH_DOMAIN_SKILLS=1 is set and a task is site-specific, the agent reads every file in the matching agent-workspace/domain-skills/<site>/ directory before inventing an approach.
The key design decision: skills are written by the harness, not by you. Just run your task with the agent -- when it figures something non-obvious out, it files the skill itself. Hand-authored skill files are discouraged; agent-generated ones reflect what actually works in the browser. The community then contributes those generated files back via pull request.
