Agent Skills moved to the Linux Foundation: 4 things SKILL.md authors should watch

Description and use

SKILL.md authors should prepare for upcoming versioning, security guidance, and unified governance while the format remains unchanged.

Problem

SKILL.md authors need to adapt to upcoming versioned releases, security guidance, and unified governance under the Agentic AI Foundation.

Outcome

SKILL.md authors can continue using the standard without interruption, but should prepare for version pinning, security checks, and unified governance to avoid future compatibility issues.

Workflow

• 1. Document current format behaviors used by each skill.
• 2. Audit scripts in third‑party skills before use.
• 3. Monitor for the first tagged spec release and pin skills to that version.
• 4. Read and apply forthcoming security guidance.

Evidence

The format itself is unchanged. A skill is still a folder with a SKILL.md file that teaches an agent a task or domain, plus any scripts and reference material it needs.

The proposed roadmap from Anthropic covers "versioned releases, a formal proposal process, and security guidance for people who write and install skills".

If that file list comes back long, that is the finding. A skill that teaches a workflow should not need a small application to do it.
