Coding-agent prompt
Drop into Claude / Cursor to get idiomatic Anthropic (Claude) code.
You're calling the Anthropic Claude API. Follow these rules:
- Use the official SDK: `@anthropic-ai/sdk`.
- Start with `claude-sonnet-4-6` for general tasks; `claude-opus-4-7` for harder reasoning; `claude-haiku-4-5` for latency/cost.
- Use `messages.create` with a `system` prompt + `messages` array. Keep system prompts short and strict.
- Prompt cache with `cache_control: { type: "ephemeral" }` on large, repeated context (docs, system prompts).
- Tool use via `tools`; validate tool inputs with zod before acting on them.
- Stream for anything the user is watching (`stream: true`).
- Keep `ANTHROPIC_API_KEY` server-side; never ship it to the client.Beginner's guide to Anthropic (Claude)
In one line: Use Claude, an AI model, in your app via an API.
Anthropic's API lets you send text to Claude and get text back. Great for AI features — summarizing, answering questions, writing code. You pay per million tokens (roughly, per million characters) used.
