Anthropic Donates Agent Skills Standard to the Linux Foundation

Summary

Anthropic donated the Agent Skills standard to the Agentic AI Foundation (AAIF), which operates under the Linux Foundation. The AAIF is the same body that hosts the MCP specification. Simon Willison notes that he predicted this move back in December, when Anthropic first described skills as an 'open standard.'

Why it matters

Transferring governance to a multi-vendor foundation co-founded by Anthropic, Block, and OpenAI signals that interoperability between agent skills has become a genuine industry concern. This mirrors the path taken by MCP: create it, drive adoption, and then hand over control. This approach offers a practical way to mitigate vendor lock-in criticisms. For developers building on agent skills, a neutral umbrella ensures the specification remains robust and less dependent on a single company's roadmap.

Highlights

• AAIF was co-founded by Anthropic, Block, and OpenAI; MCP already resides under this umbrella.
• Willison had predicted the donation back in December, when skills were first labeled an 'open standard.'
• Willison prompted Claude (via the datasette-mcp tool) to retrieve his earlier blog post where he made this prediction.

Critical take

Anthropic's 'vendor-neutral' framing is an exaggeration, given that three of the co-founders are companies that build agents using this standard. Furthermore, the article provides no details on how governance and voting mechanisms work. While having Claude retrieve Willison's own prediction is a charming meta-moment, it also highlights how tightly the ecosystem revolves around a single vendor's toolset.
