What's in the bundle?
Each skill in its own folder with the file SKILL.md (Cursor rules as .mdc), a project context file (CLAUDE.md, AGENTS.md, copilot-instructions.md or GEMINI.md), which holds your skill list and project details, and a README-di9.md short. Extract the zip in the project root and tell the agent “read the context file”.
Which skills should I combine?
Usually one skill for Workflow (planning, systematic debugging, TDD), one for Core technology (Laravel, WordPress, React) and one for Quality (code review) is enough. A bigger bundle isn't better; the agent reads only the relevant skill each time, but keeps a short description of all the skills in memory.
