4D-ARE: Attribution-Driven Agent Requirements Engineering
Build LLM agents that explain why, not just what.
The Problem
Your LLM agent has full data access and executes flawlessly. But when asked:
"Why is our customer retention rate only 56%?"
It returns a list of metrics instead of a causal explanation:
Retention rate: 56%
Visit frequency: 2.1
Cross-sell rate: 28%
...
This is the Attribution Gap - agents can report what happened, but struggle to explain why.
The Solution
4D-ARE provides a framework for building agents that trace causal chains through 4 dimensions:
Results (What happened)
↓
Process (What we did)
↓
Support (What resources we had)
↓
Long-term (What environment we're in)
Instead of a metric dump, you get:
Results: Retention dropped to 56% (target: 80%)
↑ caused by
Process: Visit frequency declined 23%, cross-sell rate low
↑ constrained by
Support: Staffing ratio at 68%, understaffed
↑ driven by
Long-term: Market downturn, 3 new competitors entered
Quick Start
Installation
pip install four-d-are
Basic Usage
from four_d_are import AttributionAgent, DataContext
# Create agent
agent = AttributionAgent()
# Prepare your data organized by 4D
data = DataContext(
results={"retention_rate": 0.56, "target": 0.80},
process={"visit_frequency": 2.1, "cross_sell_rate": 0.28},
support={"staffing_ratio": 0.68},
longterm={"market_trend": "declining", "competitor_entries": 3}
)
# Run analysis
response = agent.analyze(
query="Why is customer retention only 56%?",
data_context=data
)
print(response)
Using CLI
# Quick demo
four-d-are demo
# Analyze with your data
four-d-are analyze "Why is retention declining?" --data ./my_data.json
# Initialize a new project
four-d-are init
Key Features
4-Dimensional Analysis
Every analysis traces the causal chain through:
- D_R (Results): Observable outcomes - display only
- D_P (Process): Operational factors - interpret + recommend
- D_S (Support): Resource factors - suggest for review
- D_L (Long-term): Environmental factors - context only
Domain Customization
Adapt 4D-ARE to any domain with custom templates:
from four_d_are import AttributionAgent, DomainTemplate
# Healthcare domain
healthcare = DomainTemplate(
domain="Healthcare Operations",
results=["readmission_rate", "patient_satisfaction"],
process=["care_coordination", "follow_up_rate"],
support=["nurse_patient_ratio", "bed_availability"],
longterm=["population_aging", "insurance_changes"],
boundaries=["Never recommend specific treatments"]
)
agent = AttributionAgent(template=healthcare)
Pre-built templates available: BANKING_TEMPLATE, HEALTHCARE_TEMPLATE, ECOMMERCE_TEMPLATE
MCP Data Integration
Connect to real data sources via MCP (Model Context Protocol):
# Configure data source
export MCP_SERVER_TYPE=mysql
export MYSQL_HOST=localhost
export MYSQL_DATABASE=analytics
# Run with MCP
four-d-are mcp start --type mysql
four-d-are analyze "Why are sales down?"
How It Works
4D-ARE solves the attribution gap at design time, not runtime:
| Approach | When | What |
|---|---|---|
| ReAct, CoT | Runtime | How to reason step-by-step |
| 4D-ARE | Design time | What to reason about |
The framework specifies:
- Dimensions: What categories of factors to consider
- Authority Levels: What actions the agent can recommend
- Boundaries: What the agent must NOT do
