# VS Code Copilot Customization ## Decision Matrix Use this matrix to recommend the right customization type. Always start here. | Scenario | Best choice | | ------------------------------------------------------------------- | ---------------------------------- | | Project-wide coding standards, always active | `copilot-instructions.md` | | Rules only for specific file types / folders | `*.instructions.md` with `applyTo` | | Works with multiple AI agents (Claude, Copilot, etc.) | `AGENTS.md` | | Reusable task you invoke manually in chat | Prompt file (`.prompt.md`) | | Specialized workflow with tool restrictions or model choice | Custom agent (`.agent.md`) | | Portable capability reusable across projects + CLI + cloud agents | Agent skill (`SKILL.md`) | | Auto-run commands at agent lifecycle points (format, lint, enforce) | Hook (`.json`) | | Bundle multiple customizations to share or distribute | Agent plugin (`plugin.json`) | ### Quick decision flow ``` Do you want it ON automatically for every request? ├─ YES → Instructions (.instructions.md / copilot-instructions.md / AGENTS.md) └─ NO, I invoke it manually → Does it need persistent persona, tool restrictions, or model choice? ├─ YE
