# Concilium

> Use this tool when you need to consult multiple large language models (LLMs) in parallel and synthesize their responses to build consensus or resolve disagreements. Concilium solves problems of inconsistent or uncertain outputs from individual LLMs by providing a framework for multi-provider consultation and error detection. It takes in prompts as input and outputs synthesized responses, making it ideal for use cases requiring robust and reliable language model outputs.

## Description

Concilium provides a multi-agent consultation framework that sends prompts to multiple LLM providers in parallel and synthesizes their responses. It includes three standalone servers wrapping OpenAI Codex CLI, Gemini CLI, and Qwen CLI, each with structured error detection and configurable fallback chains. The framework supports consensus-building workflows where disagreements between providers trigger follow-up iterations. Docker support and a Claude Code skill for triggering consultations are included.
