THEN Always use the official Anthropic SDK (anthropic, @anthropic-ai/sdk, com.anthropic.*, etc.) for the project's language. Never mix SDK with raw HTTP (requests, fetch, curl) unless the user explicitly requests cURL or the project is a shell/cURL project. Never fall back to OpenAI-compatible shims.

// Python example (correct):
import anthropic
client = anthropic.Anthropic()
response = client.messages.create(model="claude-opus-4-7", max_tokens=1024, messages=[{"role": "user", "content": "Hello"}])
# Incorrect: import requests; requests.post('https://api.anthropic.com/v1/messages', ...)
