Skillsgate

SkillsGate is a free, open source desktop app for managing AI agent skills. Agent skills are reusable SKILL.md instruction files that extend what an AI coding agent can do, and SkillsGate gives developers one visual place to browse, install, edit and organize them. It runs on macOS, Windows and Linux and is released under the MIT license. It is aimed at developers who use several coding agents and want control over which skills each one has. The app detects 23 tools, including Claude Code, Cursor, Codex CLI, GitHub Copilot, Windsurf, Cline, Continue, Zed and Roo Code. A visual browser shows every installed skill across all agents with search and filtering. A skill can be installed to some agents and not others, and it is written to the correct configuration directory for each one. The Discover view reads the skills.sh catalog, lets a user preview the full SKILL.md and its install count, and fetches the chosen skill from its GitHub repository. A built in editor with markdown syntax highlighting saves edits straight to disk. Remote server management over SSH allows skills on other machines to be browsed, edited and pushed with a preview of each change. Settings, favorites and server configurations are kept in a local SQLite database on the user's machine, and no account is needed. The app is free to download.
