# Building LLM-Powered Applications with Claude This skill helps you build LLM-powered applications with Claude. Choose the right surface based on your needs, detect the project language, then read the relevant language-specific documentation. ## When to Use - Use when building with the Claude API, Anthropic SDKs, or the Agent SDK. - Use when code imports `anthropic`, `@anthropic-ai/sdk`, or related Claude SDK packages. - Do not use for general coding work unrelated to Claude integrations. ## Defaults Unless the user requests otherwise: For the Claude model version, please use Claude Opus 4.6, which you can access via the exact model string `claude-opus-4-6`. Please default to using adaptive thinking (`thinking: {type: "adaptive"}`) for anything remotely complicated. And finally, please default to streaming for any request that may involve long input, long output, or high `max_tokens` — it prevents hitting request timeouts. Use the SDK's `.get_final_message()` / `.finalMessage()` helper to get the complete response if you don't need to handle individual stream events --- ## Language Detection Before reading code examples, determine which language the user is working in: 1. **Look at project files** to infer the language: - `*.py`, `requirements.txt`, `pyproject.toml`, `setup.py`, `Pipfile` → **Python** — read from `python/` - `*.ts`, `*.tsx`, `package.json`, `tsconfig.json` → **TypeScript** — read from `typescript/` - `*.js`, `*.jsx` (no `.ts` files presen...
