Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

Multi LLM deliberation council: query frontier models in parallel, then combine their responses through structured protocols (voting, debate, synthesis, critique, red teaming, verification). Ships as an MCP server and Claude Code skill.

Features

  • Vote. Each model answers independently, then all models anonymously rank each other. Winner selected by first place votes with confidence score.
  • Debate. Multi round argumentation with optional KS statistic adaptive stopping. Chairman synthesizes the final round into a consensus answer.
  • Synthesize. Fan out to all models, then a chairman model produces an authoritative synthesis combining the best elements.
  • Critique. Models answer, then peer review each other's responses with structured feedback.
  • Red Team. Adversarial variant of critique that actively probes for flaws, hallucinations, and failure modes.
  • MAV (Model as Verifier). Cross checks a candidate answer using multiple models. Each model scores the candidate, highest scored response becomes verified output.

ToolRiskDescription
council_configurewriteUpdate the default council configuration for this session. Changes persist until the server restarts. Use this to set preferred models, chairman, or default protocol without passing them on every call.
council_critiquereadPeer critique: models answer, then critique each other
council_debatereadMulti round debate: models argue in rounds, optionally stopping early when responses converge (KS statistic). Chairman synthesizes the final round into a consensus answer.
council_deliberatewriteRun a multi LLM council deliberation. Sends the same question to multiple frontier models and combines their responses using a chosen protocol (synthesize, vote, debate, critique, redteam, or MAV verification). Returns responses, synthesis/consensus, cost breakdown, and latency.
council_estimate_costwriteEstimate the USD cost of a council run before executing it. Returns per model and total cost estimates based on token counts and current pricing.
council_statusreadCheck which LLM providers have API keys configured and list available models with their pricing. Use this to verify the council is ready before running a deliberation.
council_verifyreadMAV (Model as Verifier): cross checks an answer using multiple models. Each model scores the candidate answer, and the highest scored response becomes the verified output. Use this to fact check or validate an existing answer.
council_votereadQuick voting: each model answers, then all models rank each other
