Matt Pocock's skills collection hit v1.0 with a 63% token-cost cut from progressive disclosure.

The first semver-major since it became the most-starred Agent Skills collection on GitHub, mattpocock/skills v1.0 reports the savings by having the agent read only a skill's name and description up front, pull the SKILL.md body only when relevant, and load scripts and references only if the task needs them (explainx.ai). Agent Skills is now a cross-vendor standard across ~40 clients including Copilot, Cursor, Codex, and Gemini CLI, so the pattern is portable. Keep frontmatter descriptions sharp, push everything else behind the disclosure boundary.
