The open agent skills tool - npx skills

What it solves

This project provides a CLI tool to manage "agent skills"—reusable, portable instruction sets that extend the capabilities of various AI coding agents. It solves the problem of manually copying prompts or instructions into different AI tools, allowing users to install, update, and share specialized task instructions across a wide ecosystem of supported agents.

How it works

The CLI manages SKILL.md files, which contain YAML frontmatter (name and description) and Markdown instructions. The tool can fetch these skills from various sources including GitHub, GitLab, local paths, or direct URLs. Once fetched, it installs them into the specific configuration directories of supported agents (e.g., Claude Code, Cursor, Windsurf) using either symlinks for easy updates or direct copies.

Who it’s for

Developers who use AI coding agents and want to standardize their workflows, share specialized prompts across different tools, or create a library of reusable instructions for their team.

Highlights

  • Broad Agent Support: Compatible with over 70 coding agents, including popular tools like Claude Code, Cursor, and OpenCode.
  • Flexible Installation: Supports project-level (shared with team) or global (user-wide) installation scopes.
  • Versatile Sourcing: Can install skills from GitHub shorthand, full Git URLs, local directories, or direct file downloads.
  • Management Commands: Includes built-in commands to find, list, remove, and update installed skills.
  • Instant Use: The use command allows generating a prompt from a skill without needing to install it permanently.
