Agent skills
AI and ML Claude skills and agent skills
What ai and ml skills do
Build with model APIs and agent frameworks, train models and use AI SDKs. A skill is a folder with a SKILL.md: the agent reads its one-line description up front and loads the instructions only when a task matches, so a ai and ml skill costs almost nothing until you need it. The 15 here come from Anthropic, OpenAI, Hugging Face, Google (Gemini), Cloudflare, LangChain, ElevenLabs, OpenRouter, PostHog.
