What is skills.sh?

skills.sh is a registry and command-line tool for discovering and installing reusable capabilities—called "skills"—for AI agents. Instead of building every function from scratch, developers can browse a community-driven leaderboard of skills and add them to their agent with a single terminal command: npx skills add. Each skill packages procedural knowledge—like API integrations, data processing routines, or domain-specific workflows—so agents can perform complex tasks without custom coding.

Who it's for

• AI agent developers who want to extend their agents' abilities quickly without reinventing common functionality
• Open-source contributors looking to share reusable agent capabilities and gain visibility through install counts
• Teams building agent-based tools that need a standardized way to distribute and version procedural knowledge across projects

Key features

One-command installation

Skills are added to any agent environment with a single npx skills add command. No manual configuration, dependency hunting, or copy-pasting code—just run the command and the skill is ready to use.

Community-driven leaderboard

The skills.sh leaderboard ranks skills by total installs, showing which capabilities are most trusted and widely adopted. Developers can quickly spot popular skills from sources like Microsoft Azure, Lark Suite, and independent creators.

Curated skill collections

Skills are organized by source, with collections from major providers and individual developers. For example, microsoft/azure-skills has over 4.5 million total installs across 14+ skills, while xixu-me/skills offers 9+ skills with 1.2 million installs.

What stands out

"Skills are reusable capabilities for AI agents—install them with a single command to enhance your agents with access to procedural knowledge."

This approach treats agent capabilities as composable, shareable modules rather than monolithic codebases. The leaderboard creates a trust signal: high-install skills have been battle-tested by the community. Combined with the frictionless npx installation, skills.sh makes it practical to assemble a capable agent from pre-built parts instead of writing everything from scratch.

Worth checking out if…

You're building AI agents and want to avoid reinventing common integrations. The leaderboard gives you a quick pulse on what's working for others, and the one-command install means you can test a skill in seconds. It's especially useful if you're prototyping agents or maintaining multiple agent configurations that need consistent, versioned capabilities.
