AAIF announced on October 22, 2026, at the AGNTCon + MCPCon North America conference in San Jose, that it is taking on four new projects at once, lifting its hosted portfolio from three projects a year ago to ten. The four come from four different companies: Agent Skills, contributed by Anthropic; Open Responses, contributed by OpenAI; OpenEnv, led by Hugging Face; and OpenSandbox, contributed by Alibaba.
Four projects, four missing layers
Agent Skills fills the capability layer. It packages instructions, scripts and resources into reusable skills that agents load on demand, so specialized know-how can travel across products and platforms. David Soria Parra, co-creator of MCP at Anthropic, noted that even the smartest agents fall short without the right context; this donation follows MCP as the second Anthropic standard placed under the foundation.
Open Responses fills the interface layer. Built on OpenAI's Responses API, it defines a shared schema for requests and outputs, consistent streaming events and extensible tooling, so developers can write once and run across model providers with minimal translation. OpenEnv fills the training layer: a containerized framework for reinforcement learning environments that are interoperable and plug-and-play, speaking both MCP and the Gym protocol used by training libraries. OpenSandbox fills the execution layer: Alibaba's general-purpose sandbox platform offers multi-language SDKs, unified APIs and Docker and Kubernetes runtimes for coding agents, GUI agents, evaluation and code execution.
Why it matters
The new projects join the A2A protocol, Agent Router, agentgateway, AGENTS.md, goose and MCP under open, vendor-neutral governance. Foundation CTO Manik Surtani put it plainly: four companies chose to hand pieces of their own stack to a home no single company controls, and that choice is itself the signal. For developers, neutral standards across skills, interfaces, training environments and sandboxes should cut the cost of switching models and platforms. The open question is whether these four grow real third-party implementations the way MCP did, or stay as an announcement page.
