AnyCap is a capability runtime and CLI that augments AI agents with missing multimodal and real-world abilities — one install, one auth flow, one command — enabling agents that reason and write code to also generate images, video, audio, vision analysis, web search, storage, and publishable pages. It exposes "skills" that teach agents how to discover, install, and invoke these capabilities so models can complete end-to-end workflows (iterative media creation, asset storage/sharing, vision tasks, publishing) without developers wiring together many APIs. Developers building agent-driven apps use AnyCap to bridge the capability gap, simplify integration, and make agents production-ready so they can deliver finished outputs rather than just plans.
