Pattern: 'Skills' Are Becoming the Portable Unit of Capability Across Agent Tools

GitHub (CherryHQ/cherry-studio)·medium signal

Multiple trending repos now organize functionality as discrete, declarative skills rather than monolithic prompts: cherry-studio exposes agent-skills and an awesome-skills catalog, html-anything ships 75 skills across surfaces, and Claude Code v2.1.178 added collision-handled loading of skills from nested .claude/skills directories. The convergence suggests skills — small, named, auto-discoverable capability files — are settling in as the cross-tool packaging format for agent abilities, the way packages did for code. Builders should author capabilities as colocated skills to stay portable across Claude Code, Codex, and Cursor.
