claude-agent-sdk
Build AI agents using the Claude Agent SDK. Covers query functions, ClaudeSDKClient, custom tools, MCP servers, hooks, permissions, subagents, and browser control (Chrome extension, dev-browser skill). Use when creating agents, adding tools, configuring agent behavior, or automating browser tasks.
npx skills add majiayu000/claude-skill-registry --skill claude-agent-sdk-tdimino-claude-code-minoan --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.
<essential_principles> ## Claude Agent SDK Overview The Claude Agent SDK gives agents the same tools that power Claude Code: file operations, bash commands, web search, and more. Build autonomous agents that read files, run commands, search the web, edit code, and verify their work. ### Two Ways to Query | Function | Session | Best For | |----------|---------|----------| | `query()` | New each time | One-off tasks, automation | | `ClaudeSDKClient` | Continuous | Conversations, follow-ups, hooks | **Key Difference:** `query()` is simpler but doesn't support hooks, interrupts, or custom tools. Use `ClaudeSDKClient` for advanced features. ### Agent Loop Pattern Agents operate in a feedback loop: ``` gather context → take action → verify work → repeat ``` ### Installation **Python:** ```bash uv add claude-agent-sdk ``` **TypeScript:** ```bash npm install @anthropic-ai/claude-agent-sdk ``` **Requirements:** - Claude Code CLI installed (`npm install -g @anthropic-ai/claude-code`) - `ANTHROPIC_API_KEY` environment variable set ### Quick Start ```python import asyncio from claude_agent_sdk import query, ClaudeAgentOptions async def main(): async for message in query( prompt="Find and fix b

What does the claude-agent-sdk skill do?
Build AI agents using the Claude Agent SDK. Covers query functions, ClaudeSDKClient, custom tools, MCP servers, hooks, permissions, subagents, and browser control (Chrome extension, dev-browser skill). Use when creating agents, adding tools, configuring agent behavior, or automating browser tasks.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill claude-agent-sdk-tdimino-claude-code-minoan --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.
