Agent-skills repositories trend together on GitHub

Summary: Several repositories collecting reusable "skills" for AI coding agents trended together on GitHub on 2026-07-11. They are obra/superpowers, described as an agentic skills framework and software-development methodology (over 250,000 stars), mattpocock/skills, "skills for real engineers" drawn from the author's .claude directory (over 160,000 stars), and addyosmani/agent-skills, "production-grade engineering skills for AI coding agents" (over 75,000 stars). Each packages Markdown skill files that a coding agent loads on demand to follow a defined workflow, the same .claude/skills directory pattern used by Claude Code. All three were pushed on 2026-07-10.
Why it matters: Reusable skill files are consolidating into a shared distribution format for encoding engineering workflows into coding agents, rather than each team re-deriving prompts in isolation.
