Structural MoSCoW contracts for deterministic LLM validation.

SAMF provides machine-readable validation contracts for LLMs, translating project management MoSCoW prioritization into strict alignment guards.

**Slashes Prompt Instability:** Eliminates brittle multi-hop reasoning.**Prevents Loop Breaches:** Keeps multi-agent reasoning loops from breaking.**Optimizes Token Costs:** Reduces RAG token waste by enforcing explicit constraints.

``` python
from samf import SAMFContract, samf_contract

# Define your strict execution contract
guard_contract = SAMFContract(
    must_have=["JSON", "status", "user_id"],
    should_have=["timestamp"],
    wont_have=["error", "failed"]
)

# Enforce it seamlessly with a decorator
@samf_contract(contract=guard_contract)
def call_billing_agent():
    # Your LLM generation / LangGraph node logic here
    return '{"status": "success", "user_id": 4002, "format": "JSON"}'

response = call_billing_agent()
print("Output validated successfully!")
