Official Skills from Technology Makers

Community skills are excellent. But official skills carry a different kind of authority. When Cloudflare publishes a Workers skill, it reflects how the Cloudflare team wants you to use Workers. When Firebase publishes an agent skill, it encodes the patterns the Firebase engineers use internally. Official skills do not just teach best practices — they teach the intended practices, straight from the source.

The skills.sh/official page indexes skills from 80+ organizations that build the technology you use every day. This guide covers the most impactful ones.

When This Breaks

Official skills may lag behind the latest release. Framework teams do not always update skills on the same day they ship a new version. If you hit a pattern that contradicts the latest docs, check the skill repo’s last commit date and compare it with the framework’s release notes. Run npx skills update to pull the latest.

Large collections flood the context window. Flutter’s 45 skills and Anthropic’s 161 knowledge-work plugins are extensive. If responses feel slow or the AI starts mixing patterns, install specific skills from the collection rather than the entire repo. Check npx skills list and remove ones you do not use.

Multiple official skills overlap. Anthropic, OpenAI, and Google all publish code review skills. If you install all three, the AI may produce inconsistent review styles. Pick one and stick with it.

Install counts shift rapidly. The numbers in this guide reflect April 2026 data from skills.sh. The ecosystem grows fast — check the official directory for current numbers.
