Anthropic, OpenAI, Google, Vercel open-source their own AI skills on GitHub, barely used

Anthropic, OpenAI, Google, Vercel and Hugging Face have open-sourced the agent skills behind their own AI products on GitHub, yet adoption remains surprisingly low:
- Anthropic skills: 191.8k stars, 22.5k forks — the full library powering Claude's built-in Word, PDF, PowerPoint and Excel features
- Vercel agent skills: 33.7k stars — the rules Vercel engineers use internally: 40+ React fixes ranked by impact, a UI audit with 100+ checks, one-command deploy
- OpenAI skills: 28.6k stars — 5 ship inside Codex, 38 more passed OpenAI's internal review (fix failing CI, Figma-to-code, one-step deploy)
- Google skills: 21.5k stars — built and tested inside Google first, re-checked weekly; only skills that make agents faster and more accurate ship
Skills are folders of instructions, scripts and resources that agents load dynamically for specialized tasks — effectively reusable official productivity assets.
