Linux Foundation's AAIF adds Agent Skills, Open Responses, OpenEnv and OpenSandbox
Sorted AI24 OctThe Agentic AI Foundation under the Linux Foundation announced four new projects on 22 October: Agent Skills from Anthropic, Open Responses from OpenAI, OpenEnv from Hugging Face, and OpenSandbox from Alibaba. That brings AAIF to 10 hosted projects in its first year, up from three at launch in December 2025. Open Responses is an open specification for multi-provider LLM interfaces based on the OpenAI Responses API; OpenEnv is a framework for creating interoperable reinforcement-learning environments; OpenSandbox is a general-purpose sandbox platform with Docker and Kubernetes runtimes. Agent Skills was already covered when Anthropic donated it; this press adds the other three under the same neutral governance.
Why it matters: If you build agents that must work across vendors, Open Responses and OpenSandbox are the pieces to watch: a shared request and streaming schema, and a common place to run untrusted agent code.
