📖 About This Skill

name: mistral-agents-orchestrator description: Multi-agent orchestration via Mistral's Agents API — register agents, manage conversations, delegate via handoffs, bind function calling tools. Use when building multi-agent systems with Mistral models, coordinating specialist agents, or implementing agent-to-agent delegation patterns. Requires MISTRAL_API_KEY. version: 1.0.1 metadata: { "openclaw": { "emoji": "\ud83e\udd16", "requires": { "bins": [], "env": [ "MISTRAL_API_KEY" ] }, "primaryEnv": "MISTRAL_API_KEY", "network": { "outbound": true, "reason": "Calls Mistral Agents API (api.mistral.ai) for agent registration, conversations, and handoff delegation." }, "security_notes": "base64 used for encoding message payloads in API requests — standard format. UploadFile is a FastAPI type used for document ingestion to agent tools. 'system prompt' refers to Mistral agent configuration field — a standard API parameter, not prompt injection." } }

Mistral Agents Orchestrator

Production-tested multi-agent orchestration using Mistral's Agents API. Implements the orchestrator-delegate pattern where a lead agent coordinates specialist agents via Conversations and Handoffs.

Architecture

Orchestrator (Papa Bois pattern)
├── Registers specialist agents via Agents API
├── Creates conversations with handoff configuration
├── Delegates tasks by naming the target agent
└── Collects results from completed handoffs
Specialists (Anansi, Devi, Firefly patterns)
├── Receive delegated tasks with full conversation context
├── Execute their speciality (story gen, audio, code)
└── Return results to the orchestrator conversation

Key Concepts

Agents: Pre-registered on Mistral platform with specific system prompts and model configs. Each agent has a unique ID (ag_...).

Conversations: Multi-turn threads that preserve context across handoffs. The child's name, language, and prompt all carry through without re-injection.

Handoffs: The orchestrator names a specialist agent; Mistral routes the conversation to that agent. Context is preserved automatically.

Function Calling: Tools (like TTS, SFX) are bound to the orchestrator agent, not the delegates. Tools follow the conversation context.

Quick Start

from mistralai import Mistral
client = Mistral(api_key=os.environ["MISTRAL_API_KEY"])
Register agents (one-time setup)

orchestrator = client.beta.agents.create(
    model="mistral-large-latest",
    name="orchestrator",
    instructions="You coordinate specialist agents...",
)
specialist = client.beta.agents.create(
    model="mistral-large-latest",
    name="writer",
    instructions="You write content when delegated to...",
)
Create conversation with handoff

response = client.beta.conversations.create(
    agent_id=orchestrator.id,
    inputs="Write a blog post about AI agents",
    handoffs=[{"agent_id": specialist.id, "name": "writer"}],
)

Patterns Learned

  • Handoffs preserve conversation context — no need to re-inject background info
  • Tools bind to the orchestrator, not delegates — delegates can request tool calls but execution happens in the orchestrator's context
  • 4 agents is the sweet spot for hackathon scope — more agents = more API calls = more coordination overhead without proportional value
  • JSON mode on delegates forces structured output reliably — without it, Mistral Large sometimes returns prose instead of scene arrays

  • references/agent-patterns.md — Common multi-agent patterns and when to use each

    • Security Notes

    This skill uses patterns that may trigger automated security scanners:

  • base64: Used for encoding audio/binary data in API responses (standard practice for media APIs)
  • UploadFile: FastAPI's built-in file upload parameter for STT/voice isolation endpoints
  • "system prompt": Refers to configuring agent instructions, not prompt injection

    • 💡 Examples

    from mistralai import Mistral
    client = Mistral(api_key=os.environ["MISTRAL_API_KEY"])
    Register agents (one-time setup)
    
orchestrator = client.beta.agents.create(
    model="mistral-large-latest",
    name="orchestrator",
    instructions="You coordinate specialist agents...",
)
    specialist = client.beta.agents.create(
    model="mistral-large-latest",
    name="writer",
    instructions="You write content when delegated to...",
)
    Create conversation with handoff
    
response = client.beta.conversations.create(
    agent_id=orchestrator.id,
    inputs="Write a blog post about AI agents",
    handoffs=[{"agent_id": specialist.id, "name": "writer"}],
)
