[octo-patch]

Summary

• Add @supermemory/tools/minimax integration module for MiniMax LLM provider
• Provide withSupermemory() wrapper that wraps MiniMax OpenAI-compatible clients with persistent memory middleware
• Export clampTemperature() utility for MiniMax temperature range constraint (0, 1.0]
• Export MINIMAX_MODELS constant with MiniMax-M2.7 and MiniMax-M2.7-highspeed models
• Re-export all OpenAI memory tools (searchMemories, addMemory, getProfile, etc.) for MiniMax clients
• Add MiniMax to README framework integrations section

Changes

File	Change

Usage

import OpenAI from "openai"
import { withSupermemory, clampTemperature } from "@supermemory/tools/minimax"

const minimax = new OpenAI({
  apiKey: process.env.MINIMAX_API_KEY,
  baseURL: "https://api.minimax.io/v1",
})

const client = withSupermemory(minimax, "user-123", {
  mode: "full",
  addMemory: "always",
})

const response = await client.chat.completions.create({
  model: "MiniMax-M2.7",
  messages: [{ role: "user", content: "What do you know about me?" }],
  temperature: clampTemperature(0.7),
})

Test plan

• 19 unit tests pass (model constants, temperature clamping, wrapper creation, tool re-exports)
• 3 integration tests pass (MiniMax API chat completion with M2.7 and M2.7-highspeed)
• Verify build with bun run build in packages/tools
