About
Anthropic's collection of demos for the Claude Agent SDK — reference implementations of agents, tools, and workflows.
What it does
A hands-on sampler for learning how Claude-driven applications behave beyond a basic prompt. Its examples span streaming chat, persistent conversations, tool permissions, browser-mediated questions, parallel research, email interaction, spreadsheet work, and document generation.
Why it's ranked here
The breadth makes this a useful orientation kit, especially because it shows both tiny scripts and complete browser flows. The strongest examples expose practical control points such as tool restrictions, pre-use hooks, streamed events, session resumption, and user approval. Its explicit local-only warning sharply limits its value as production guidance.
What's good
The examples teach through concrete contrasts. One shows the simplest streamed query, while another separates sending from streaming and preserves context across sessions. Browser demos connect model events to visible status updates over WebSockets. Tool controls include allowlists, denial paths, plan mode, and a hook that blocks script writes outside a designated directory.
Tradeoffs
Anthropic labels every application as demo code for local development, not production or scale. The email assistant is still in development, and the session-based examples use an unstable interface. Setup is fragmented across demo-specific instructions. Several examples grant powerful capabilities such as shell access, file writes, web search, or broad tool lists.
How to use it well
Use it when prototyping an SDK integration or comparing conversation, tool, session, and browser interaction patterns. Start with the small streaming and session examples, then borrow one complete flow matching your product. Treat permissions and error paths as teaching material. It does not cover production hardening, deployment, scaling, or operational support.
Technical notes+
hello-world/hello-world.ts calls query with maxTurns: 100, an allowedTools list, and a PreToolUse hook that blocks JavaScript or TypeScript writes outside agent/custom_scripts. hello-world-v2/v2-examples.ts demonstrates unstable_v2_createSession, unstable_v2_resumeSession, and unstable_v2_prompt, including multi-turn streaming and cost output. ask-user-question-previews/server.ts uses an HTTP server plus WebSocketServer, keeps pending browser answers in a request-keyed Map, restricts tools to AskUserQuestion, and enables HTML previews. resume-generator/resume-generator.ts permits web, shell, and file tools, loads project settings, and checks for a generated DOCX. simple-chatapp/vite.config.ts proxies API and WebSocket traffic to port 3001.
