Agent Skills moves to AAIF: Anthropic donates the open skill standard
Quotable summary
Anthropic donated Agent Skills — the open folder/SKILL.md format for packaging agent workflows — to the Linux Foundation’s Agentic AI Foundation (AAIF) on 22 October 2026. The name, logo, GitHub organization, and agentskills.io domain go with it. AAIF also announced sibling projects the same day. For builders: skills stay usable without joining AAIF; watch the roadmap for versioning, proposals, and security guidance.
What changed
| Item | Detail |
|---|---|
| Event | Donation of Agent Skills to AAIF (under Linux Foundation) |
| Date | 22 October 2026 (Anthropic + AAIF posts) |
| What transferred | Agent Skills name and logo, GitHub organization, agentskills.io domain |
| Format | A skill is a folder with a SKILL.md plus optional scripts/reference files |
| Maintainers (named) | David Soria Parra and Mahesh Murag as lead maintainers; engineers from Anthropic, Google, OpenAI, and others as individuals |
| Membership required? | No — Anthropic says you can use or contribute without joining AAIF |
| Same-day AAIF cohort | Open Responses (OpenAI), OpenEnv (Hugging Face), OpenSandbox (Alibaba) — AAIF says portfolio grows to 10 hosted projects |
Anthropic frames Skills as the portable procedural layer agents need beyond general chat: load instructions and tools on demand across products. It lists ChatGPT, Cursor, GitHub Copilot, and VS Code among platforms that integrated the standard since publication in December 2025.

What builders should do
- Keep using existing
SKILL.mdpacks — Anthropic says the standard remains open under AAIF stewardship. - Track governance: proposed roadmap covers versioned releases, a formal proposal process, and security guidance for authors and installers (malicious skills can ship scripts and network calls).
- Audit third-party skills before install: read scripts, dependencies, and required permissions; Agent Skills’
compatibility/ tool-permission fields vary by host. - Note the wider AAIF stack if you care about multi-provider interfaces (Open Responses), RL environments (OpenEnv), or sandboxed execution (OpenSandbox) — announced alongside Skills, not required to keep shipping skills.
- No cost/latency numbers in this piece: the donation is governance/interop news, not a model or infra pricing change.
