Daily AI Agent Leaderboard Launches: Best Skills Tracks 10,000 Extensions to Rank Top 100

Linkly AI has launched Best Skills, an open analytics platform for monitoring and evaluating extensions built for autonomous AI assistants. The platform daily scans over 10,000 Agent Skills across databases including skills.sh, ClawHub, Tencent SkillHub, and GitHub, compiling an independent Top 100 chart based on a comprehensive utility index.

WIS Index: Why Millions of Downloads Don’t Guarantee First Place

Unlike standard directories that rank plugins solely by download count, the Best Skills ranking calculates its own weighted metric, the Worth-Installing Score (WIS), on a scale from 0 to 100.

The evaluation formula incorporates five key factors:

• Popularity and downloads: 30%;
• GitHub stars and reputation: 20%;
• Author/publisher trust: 20%;
• Weekly growth momentum: 15%;
• Update frequency and support: 15%.

Through data normalization, the tool filters out artificial inflation and outdated packages. For example, the meta-plugin find-skills leads in total installations (over 3.19 million), but lags behind higher-quality solutions from Vercel and Anthropic in overall rankings.

Leader Breakdown: Top 3 AI Agent Skills

1. agent-browser (Vercel Labs)
Turns a neural network into a full-fledged browser operator based on Chromium or a custom Chrome profile. The agent gains the ability to click interface elements, fill out forms, bypass authentication via cookies, run JavaScript scripts, and test dynamic web pages.

• Installation: npx skills add https://github.com/vercel-labs/agent-browser –skill agent-browser

2. frontend-design (Anthropic)
An official skill from the creators of Claude designed to eliminate generic “AI look” from generated interfaces (cookie-cutter gradients and boring layouts). The plugin forces the model to plan visual style, custom typography, animations, and color palettes for React, Vue, or vanilla HTML/CSS before writing code.

• Installation: npx skills add https://github.com/anthropics/skills –skill frontend-design

3. find-skills (Vercel Labs)
A self-learning tool for agents: when facing an unfamiliar task, the assistant independently searches open registries for a suitable extension (such as PDF parsing or database integration) and prompts the user to install it.

• Installation: npx skills add https://github.com/vercel-labs/skills –skill find-skills

What Are Agent Skills and Where Do They Work?

The Agent Skills format is an open standard for modular instructions created according to the agentskills.io specification. In its basic form, a skill consists of a SKILL.md manifest containing system instructions, executable scripts, and context templates.

Once configured, a skill is supported across a wide range of clients: Claude Code, Cursor, OpenAI Codex, GitHub Copilot, Windsurf, Gemini, Cline, and Antigravity.

An Important Security Note

As noted in the methodology on the project’s GitHub repository, a high WIS score is not a code security audit.

Extensions can contain executable system scripts in Bash, Python, or JavaScript that the agent runs locally on the developer’s computer. Experts recommend using the skills.sh directory and Best Skills charts as an analytical radar for discovering promising tools, while making sure to inspect manifests and source code before adding them to a production environment.
