Agent Skills
Instruction packs that give your AI agent know-how — some work anywhere, some only with the tool they came with.
✦ Standalone skills3,264
Self-contained. Install one into any project and it works on its own — no other software needed.
🧰 Tool add-ons529
Come bundled with a specific tool and only work together with it — they teach your agent how to operate that tool.
🔌 Needs setup first122
Each relies on something you set up separately — such as an app, a command-line tool or an account — and its page names what that is.
