claude-agent-sdk
Build custom AI agents using Anthropic Claude API and agent SDK patterns. Create tool-using agents, multi-turn conversations, agent loops, streaming responses, and production-ready agent architectures. Use when building Claude-powered applications, implementing agentic AI features, or developing autonomous task completion systems.
npx skills add majiayu000/claude-skill-registry --skill claude-agent-sdk-housegarofalo-claude-code-base-2 --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill claude-agent-sdk-housegarofalo-claude-code-base-2 --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
