Multi-agent consensus system - LLM agents with different prompts analyze problems, critique each other, iterate to agreement
Project description
Consult
Multi-agent consensus system. Multiple LLM agents analyze your problem from different angles, critique each other's outputs, and iterate until they agree or an orchestrator resolves disagreements.
The value isn't individual agent outputs - it's the structured peer review that catches blind spots any single perspective would miss.
What This Does
- Parallel analysis: N agents with domain-specific prompts analyze your problem simultaneously
- Peer feedback: Each agent reviews the others' outputs with structured critique
- Meta review: Separate pass catches integration issues the domain-focused agents miss
- Iteration: Agents incorporate feedback and revise (configurable cycles)
- Resolution: Either consensus is reached or an orchestrator synthesizes disagreements

Installation
pip install getconsult
Configure API key:
mkdir -p ~/.consult
echo 'ANTHROPIC_API_KEY=sk-ant-...' > ~/.consult/.env
chmod 600 ~/.consult/.env
Or export directly:
export ANTHROPIC_API_KEY=sk-ant-...

# Basic query
consult -p "Design a real-time chat application database"
# Check status
consult --status
# List available agent configurations
consult --list-experts
# Interactive mode (Pro tier)
consult-tui

Agent Types
Each agent type has a domain-focused system prompt that shapes how it analyzes problems. The peer review mechanism means a security-focused agent will catch issues a performance-focused agent might overlook, and vice versa.
| Agent Type | Focus |
|---|---|
database |
Data modeling, queries, consistency, migrations |
backend |
API design, service boundaries, error handling |
infrastructure |
Deployment, scaling, monitoring, reliability |
security |
Threat models, auth, input validation, compliance |
performance |
Bottlenecks, caching, profiling, optimization |
architect |
System design, trade-offs, patterns |
cloud |
Cloud services, IaC, containers, DevOps |
frontend |
UI architecture, state management, rendering |
ml |
ML systems, training, inference, MLOps |
data |
Pipelines, ETL, streaming, warehousing |
ux |
User research, interaction design, accessibility |
Predefined Sets
consult -p "..." --experts default # database, backend, infrastructure
consult -p "..." --experts architecture # architect, database, cloud
consult -p "..." --experts security_focused # security, backend, infrastructure
consult -p "..." --experts full_stack # backend, frontend, database, infrastructure
Custom Selection (Pro)
consult -p "..." --experts "database,security,performance"
How Consensus Works
Consensus isn't "do the outputs look similar" - it's "would each agent approve the others' solutions for production."
Approval Voting
Each agent reviews each OTHER agent's solution:
3 agents = 6 pairwise reviews:
Agent A → B's solution: APPROVE (1.0)
Agent A → C's solution: CONCERNS (0.7)
Agent B → A's solution: APPROVE (1.0)
Agent B → C's solution: OBJECT (0.0)
Agent C → A's solution: CONCERNS (0.7)
Agent C → B's solution: APPROVE (1.0)
Aggregate: (1.0 + 0.7 + 1.0 + 0.0 + 0.7 + 1.0) / 6 = 73%
Verdicts
| Verdict | Score | Meaning |
|---|---|---|
| APPROVE | 1.0 | Production-ready |
| CONCERNS | 0.7 | Acceptable with noted issues |
| OBJECT | 0.0 | Fundamental problems |
Resolution
≥80% approval → consensus reached → format output
<80% AND iterations left → revise and re-vote
<80% AND max iterations → orchestrator synthesizes

License Keys
export CONSULT_LICENSE_KEY="CSL1_pro_..."
# or
echo "CSL1_pro_..." > ~/.consult/license
Check status:
consult --status
Configuration
# ~/.consult/.env
# API keys (at least one required)
ANTHROPIC_API_KEY=sk-ant-...
OPENAI_API_KEY=sk-...
GOOGLE_API_KEY=...
# Model overrides (defaults optimized for cost, Dec 2025)
ANTHROPIC_MODEL=claude-haiku-4-5-20251001
OPENAI_MODEL=gpt-4o-mini
GEMINI_MODEL=gemini-2.5-flash-lite
# For higher quality (and cost)
# ANTHROPIC_MODEL=claude-sonnet-4-20250514
# OPENAI_MODEL=gpt-4o
# Meta reviewer / orchestrator model
SOTA_MODEL=claude-opus-4-5-20251101
# Data directory
CONSULT_HOME=~/.consult
Data Directory
~/.consult/
├── sessions/ # Conversation state (Pro)
├── outputs/ # Markdown exports (Pro)
├── cache/ # Quota tracking
└── logs/ # Debug logs (API keys redacted)
Team Mode (Pro)
Runs the same agent configurations across multiple providers in parallel:
consult -p "Compare approaches to real-time sync" --mode team
Spawns agents on OpenAI, Anthropic, and Google simultaneously, then compares outputs across providers.
Programmatic Usage
from src.workflows import ConsensusWorkflow
workflow = ConsensusWorkflow(
consensus_threshold=0.8,
expert_config="architecture"
)
result = await workflow.solve_problem("Design microservices architecture")
print(f"Consensus: {result.consensus_achieved}")
print(f"Resolution: {result.resolution_method}")
print(result.final_solution)
Performance
| Operation | Typical Time |
|---|---|
| 3-agent consensus | 120-180s |
| Team mode (9 agents) | 180-300s |
Dominated by LLM API latency.
Security
- API keys never written to logs, sessions, or outputs
- Sensitive data redacted before persistence
- Session files use hashed identifiers
chmod 600 ~/.consult/.env
Development
git clone https://github.com/1x-eng/agentic-atlas.git
cd agentic-atlas
pip install -e ".[dev]"
