About developer tools skills
What are developer tools skills for AI agents?
They are SKILL.md packages that teach an AI agent how to handle developer tools tasks. Each bundles instructions, and often scripts and reference files, that the agent loads when your request matches what the skill does.
Do these skills work outside Claude Code?
Yes. SKILL.md is an open standard, so the same folder works in Claude Code, Codex CLI, Cursor, Antigravity, Cowork, Windsurf and Copilot. Only the install path changes.
How much do they cost?
Every skill listed is free and open source. We link to the original repository so you can read the code before installing.
