Pattern: Agent Skills Are Becoming the Universal Capability-Packaging Format

GitHub·medium signal

Across the ecosystem, capabilities are now shipped as portable 'skills' (Markdown workflow modules): language-specific packs like samber/cc-skills-golang, 1,600+ cross-tool libraries, harnesses like DeerFlow with built-in skills, and even Google's Workspace CLI bundling agent skills. The unit of reuse has shifted from prompts and MCP tools to skills that travel across Claude Code, Cursor, Codex, and Gemini. Package your own workflows as skills for portability.
