Mistral SDK Patterns

Quick Guide: Use @mistralai/mistralai (ESM-only) to interact with Mistral's API. Use client.chat.complete() for chat, client.chat.stream() for streaming (async iterable via for await), client.chat.parse() with a Zod schema for structured outputs, and client.fim.complete() for Codestral fill-in-middle code completion. The SDK uses responseFormat (camelCase) not response_format. Streaming events expose content via event.data.choices[0]?.delta?.content. Retries default to strategy: "none" -- you must configure them explicitly for production.

CRITICAL: Before Using This Skill

All code must follow project conventions in CLAUDE.md (kebab-case, named exports, import ordering, import type, named constants)

(You MUST use responseFormat (camelCase) in SDK calls -- NOT response_format (snake_case). The SDK uses camelCase property names throughout.)

(You MUST configure retries explicitly -- the SDK defaults to strategy: "none" (no retries), unlike OpenAI's SDK which retries automatically)

(You MUST consume streaming results with for await (const event of result) and access content via event.data.choices[0]?.delta?.content -- the event shape differs from OpenAI)

(You MUST never hardcode API keys -- use process.env["MISTRAL_API_KEY"] with the bracket notation the SDK documents)
