I build skillstui offers a convenient terminal user interface for discovering and installing skills from the skills.sh catalog directly into AI coding agents. This tool streamlines the process for developers and AI agent users looking to enhance their agents' capabilities. With I build skillstui, users can search the extensive skills.sh library from their terminal, select specific skills, and then choose which of their supported AI coding agents should receive them. The tool supports over 30 popular agents, including Claude Code, Cursor, Windsurf, GitHub Copilot, and Gemini CLI. It automates the installation by running npx skills add for each selected skill across the chosen agents with a simple Ctrl+G command. Alternatively, users can copy the installation command to their clipboard using Ctrl+Y for manual execution. I build skillstui simplifies agent customization, allowing users to quickly equip their AI coding assistants with new functionalities without navigating multiple tools or manually typing complex commands. This results in a more efficient workflow for extending AI agent capabilities.
