Pattern: SKILL.md Is Quietly Becoming the Cross-Vendor Agent Instruction Format
Anthropic's `SKILL.md` convention is now shipping GA inside a competitor's product: Copilot code review reads skills from `.github/skills/<name>/SKILL.md` as of July 29. The same week, refly-ai/refly (7,469 stars) positions itself as a skills builder that exports to Claude Code, Cursor, and Codex, and rohitg00/pro-workflow (2,710 stars) ships a bundle installable into "32+ agents" via a cross-agent installer. If you author skills, write them once against the Markdown-plus-frontmatter shape and treat the per-tool install path as the only variable.
