Introducing SiteSkills: The Marketplace for AI Browser Agent Skills

February 1, 2026

AI browser agents are one of the most exciting developments in automation. Tools like Claude Computer Use, Browser Use, and Stagehand can navigate websites, fill out forms, and complete multi-step workflows -- all from a natural language prompt. In the last year alone, browser agents have gone from research demos to production-ready tools that thousands of developers rely on every day.

But there is a problem nobody has solved yet: every agent is an island.

The Problem: Reinventing the Wheel, Every Single Time

When you ask a browser agent to "add this product to my Amazon cart," it has to figure out the entire interaction from scratch. It needs to locate the Add to Cart button, handle variant selection, deal with out-of-stock notices, navigate CAPTCHA challenges, and verify the item actually landed in the cart.

Sometimes it works. Sometimes it clicks the wrong thing. Sometimes it gets stuck in a login redirect loop.

Now multiply that across every website, every workflow, and every agent. Developers building on Browser Use write their own Amazon navigation logic. Teams using Claude Computer Use write theirs. Stagehand users write theirs. Everyone solves the same problems independently, and nobody benefits from each other's work.

This is where packages and ecosystems have transformed every other area of software. JavaScript has npm. Python has PyPI. Rust has Crates. But browser agents? They have nothing. No shared library of "how to navigate Amazon." No way to say "someone already figured out how to book a flight on United.com -- let me use their work."

That is what SiteSkills fixes.

What Is SiteSkills?

SiteSkills is a marketplace for AI browser agent navigation skills -- structured, reusable instructions that tell browser agents how to interact with websites.

A skill is not executable code. It is a directory containing:

• SKILL.md -- a step-by-step navigation flow written in Markdown. This is what the agent reads at runtime.
• siteskills.json -- machine-readable metadata including target domains, compatible agents, failure modes, and more.
• README.md -- human documentation for developers browsing the marketplace.

Skills are portable, agent-agnostic, and secure by design. They contain no JavaScript, no Python, no scripts of any kind. They are instructions -- detailed, structured instructions that any browser agent can follow.

Think of it this way: a SiteSkills skill is to a browser agent what a recipe is to a chef. The recipe does not cook the food. But it tells the chef exactly what to do, in what order, and what to watch out for.

How It Works

The SiteSkills ecosystem has three parts:

1. The Marketplace

Browse and search hundreds of skills at siteskills.ai/skills. Filter by category (e-commerce, finance, travel, healthcare, and more), compatible agent, difficulty, and pricing. Every skill page shows real-world success rates based on community execution data.

2. The CLI

Install and publish skills from your terminal:

# Install the CLI
npm install -g siteskills

# Search for skills
siteskills search "amazon cart"

# Install a skill
siteskills install amazon-add-to-cart

# Create and publish your own
siteskills init
siteskills publish ./my-skill/

The CLI auto-detects your agent environment and installs skills to the correct directory. It works with Claude Cowork, Browser Use, Stagehand, and any custom agent setup.

3. The Security Scanner

Every skill uploaded to SiteSkills goes through a 3-stage automated scanning pipeline: static analysis, permission analysis, and content analysis. Skills that score 80 or above are auto-approved. Lower scores go to manual review. Nothing reaches the marketplace without passing the scanner.

Why Instructions, Not Code?

This is the most common question we get, and the answer comes down to three things: security, portability, and longevity.

Security. Executable code in browser automation is a supply chain attack waiting to happen. A malicious npm package can steal cookies and credentials. A SiteSkills skill cannot -- it literally has no mechanism to execute arbitrary logic. The agent reads the instructions and decides what to do.

Portability. Different agents use different programming languages, different browser control mechanisms, and different architectures. Code written for Browser Use will not run in Claude Computer Use. But Markdown instructions work everywhere. The SiteSkills template format is a superset of Anthropic's SKILL.md format, which means any agent that understands SKILL.md can use SiteSkills skills without modification.

Longevity. Websites change constantly. When Amazon moves a button, a hardcoded Playwright script breaks silently. A SiteSkills skill includes DOM hints in priority order (IDs, classes, text content, ARIA labels) plus explicit fallback strategies. This layered approach makes skills resilient to minor layout changes and easy to update when larger changes happen.

For Creators

SiteSkills is not just a place to download skills -- it is a platform for creators to share and monetize their expertise. If you understand how to navigate a complex website reliably, that knowledge has value.

Creators can publish free or paid skills. Paid skills use Stripe Connect for payouts, and creators keep 85% of every sale. The platform handles billing, delivery, and access control. A creator leaderboard highlights top contributors, and high-volume creators earn recognition and priority support.

What Comes Next

We are launching with support for three major agent platforms (Claude Computer Use, Browser Use, and Stagehand) and 17 skill categories spanning e-commerce, finance, travel, healthcare, government services, and more.

But this is just the beginning. Our roadmap includes:

• Automated skill generation -- point the platform at a website and let AI draft the first version of a skill
• Live monitoring -- real-time alerts when a skill's success rate drops, so creators can update before users notice
• Skill composition -- chain multiple skills together into complex workflows
• Enterprise features -- private skill registries for organizations that want to share skills internally

The future of AI browser automation is not every agent figuring out every website on its own. It is a shared ecosystem where the best navigation knowledge is captured once, verified continuously, and available to every agent.
