  "summary": "On October 22, 2026, Anthropic donated the Agent Skills standard to the Agentic AI Foundation under the Linux Foundation, making it vendor-neutral. This change allows the same skill folder format, SKILL.md, to be used across Claude Code, OpenAI Codex, and Gemini CLI, eliminating the need for vendor-specific implementations. The article provides a step-by-step guide on building a writing-quality skill using a dependency-free Python checker, demonstrating how easy it is to deploy the skill across all three agents.",
