Project Skills for Mac: Reusable AI Agent Instructions
Project Skills is a native Mac app for creating, organizing, and installing reusable instructions for AI coding agents. A skill is a folder with a SKILL.md file and any supporting files the agent needs. Save a code review checklist, an accessibility test plan, or a release process as a skill and reuse it across projects.
Project Skills is a native Mac app for turning the instructions you give AI coding agents into reusable skills. If you keep explaining how to review an API change, test for accessibility, or prepare a release, you can write those instructions once and give your agent the same guidance across projects.
A skill is a folder containing a SKILL.md file and any supporting material the agent needs. For example, an API review skill could define what counts as a breaking change and include sample requests the agent can refer to. Keeping that guidance together makes it easier to refine as your project evolves and share with teammates.
When you’re ready to use a skill, install it in your project. If you use Codex in Xcode, paste the prompt from Project Skills into your conversation and describe the task you want Codex to perform. The prompt points Codex to the installed skill so it can read your instructions alongside the project code.
