Donating Agent Skills to the Agentic AI Foundation News today from Anthropic: We’re committed to keeping Agent Skills open, community-driven, and vendor-neutral. Today, we are donating the standard to the Agentic AI Foundation (AAIF) under the Linux Foundation, which we co-founded with Block and OpenAI last year, and to which we donated the Model Context Protocol (MCP). I'm pleased to note I called this one last December , when Anthropic first declared skills to be an "open standard": I wouldn't be surprised to see this end up in the AAIF , recently the new home of the MCP specification. Fun side note: since my blog content is available to Claude via the datasette-mcp plugin I found that post by prompting Claude to " Use simonwillison.net MCP to find if I ever talked about how I want skills to be donated to a standards body ".

The company said it will cut off live internet access for all internal evaluations until it can reliably monitor and control its agents, citing insufficient alignment training for skills like search and computer use.

A leaked draft of an AI safety bill from Anthropic has drawn criticism from safety advocates for being weaker than the bipartisan FRONTIER Act, with provisions requiring judicial approval before federal agencies could block a model's release, potentially only if 50 or more people could be killed. In response, Anthropic CEO Dario Amodei defended the company's 'race to the top' approach, citing nine safety decisions with 'substantial costs,' and admitted mishandling the draft bill.
