What are the best Claude skills for AI engineering?
Right now the top-ranked ai engineering skills on Alyn are MCP Builder (Anthropic), Skill Creator (Anthropic), Domain Modeling (Matt Pocock). Rankings combine GitHub stars, installs, freshness and depth, and update live.
How do I create my own skill?
Write a folder with a SKILL.md file: YAML frontmatter with name and description, then instructions. See Alyn's guide on creating skills.
Do self-written skills help?
The SkillsBench study found curated skills raised pass rates by 16.2 points on average, while skills the model wrote for itself gave no benefit on average. Quality matters.
How do I install a ai engineering skill?
Run npx skills add owner/repo in your project, or copy the folder with SKILL.md into ~/.claude/skills. Every skill on this page has a ready-to-copy command.
