AgentAssert

Design-by-Contract for AI Agents

AgentAssert brings formal behavioral contracts to autonomous AI agents. Define what an agent must do, must never do, and how it should degrade under uncertainty — then enforce those rules at runtime, every invocation, across any model provider.

The Problem

The Problem

Enterprises are deploying autonomous agents at scale, yet not a single mainstream framework offers formal guarantees on what those agents will actually do. Agents drift from instructions, hallucinate tool calls, leak PII in conversation chains, and exceed cost budgets silently. The result is a reliability gap that widens with every deployment.

How It Works

Key Capabilities

01

Hard and Soft Constraints

Separate inviolable safety boundaries from aspirational quality targets. Hard constraints halt execution on violation; soft constraints degrade gracefully and log for review.

02

Real-Time Drift Detection

Continuously monitors agent behavior against its contract during execution. Detects semantic drift before it compounds into a catastrophic failure downstream.

03

Reliability Scoring

Produces a single composite reliability score (Θ) per agent per session. Enables objective comparison across model providers, prompt versions, and deployment configurations.

04

Multi-Agent Pipeline Contracts

Compose individual agent contracts into pipeline-level guarantees. When Agent A hands off to Agent B, the contract enforces interface-level expectations at the boundary.

05

Enterprise-Ready Compliance

Designed with the EU AI Act in mind. Provides the audit trail, constraint documentation, and runtime evidence that regulators and compliance teams require for high-risk AI systems.
