Quorum — Multi-Agent Validation

Quorum validates AI agent outputs by spawning multiple independent critics that evaluate artifacts against rubrics. Every criticism must cite evidence. You get a structured verdict.

Quick Start

Clone the repository and install:

git clone https://github.com/SharedIntellect/quorum.git
cd quorum/reference-implementation
pip install -r requirements.txt

Run a quorum check on any file:

python -m quorum.cli run --target <path-to-artifact> --rubric <rubric-name>

Built-in Rubrics

research-synthesis — Research reports, literature reviews, technical analyses
agent-config — Agent configurations, YAML specs, system prompts

Depth Profiles

quick — 3 critics, no fix rounds, 5-15 min
standard — 6 critics, 1 fix round on CRITICAL, 15-30 min (default)
thorough — All 9 critics + external validator, ≤2 fix rounds, 45-90 min

Examples

# Validate a research report
python -m quorum.cli run --target my-report.md --rubric research-synthesis

# Quick check (faster, fewer critics)
python -m quorum.cli run --target my-report.md --rubric research-synthesis --depth quick

# List available rubrics
python -m quorum.cli rubrics list

# Initialize config interactively
python -m quorum.cli config init

Configuration

On first run, Quorum prompts for your preferred models and writes quorum-config.yaml. You can also create it manually:

models:
  tier_1: anthropic/claude-sonnet-4-6    # Judgment roles
  tier_2: anthropic/claude-sonnet-4-6    # Evaluation roles
depth: standard

Set your API key:

export ANTHROPIC_API_KEY=sk-ant-...
# or
export OPENAI_API_KEY=sk-...

Output

Quorum produces a structured verdict:

PASS — No significant issues found
PASS_WITH_NOTES — Minor issues, artifact is usable
FAIL — Critical or high-severity issues that need resolution

Each finding includes: severity (CRITICAL/HIGH/MEDIUM/LOW), evidence citations pointing to specific locations in the artifact, and remediation suggestions.
