Formal Agent Contracts: Bring Mathematical Rigor to Multi-Agent Development
The article introduces a Claude Code plugin called 'Formal Agent Contracts' that allows developers to define precise, machine-verifiable contracts between AI agents using VDM-SL. The plugin provides a pipeline to define contracts, verify specifications, automatically prove properties, and generate code with runtime contract checks.
Why it matters
This plugin can help improve the reliability and robustness of multi-agent AI systems by ensuring formal verification of agent contracts.
Key Points
- 1Defines agent contracts using natural language that are automatically converted to formal VDM-SL specifications
- 2Verifies specifications, generates proof obligations, and uses SMT solvers to automatically prove properties
- 3Generates TypeScript or Python code scaffolds with runtime contract enforcement
- 4Provides an integrated workflow to define, verify, prove, and generate code from agent contracts
Details
The 'Formal Agent Contracts' plugin aims to address the common problem of misaligned assumptions between collaborating AI agents. It allows developers to define agent contracts in plain English, which are then automatically converted to formal VDM-SL specifications. The plugin provides a pipeline of skills to verify the specifications, automatically generate proof obligations, and use SMT solvers to prove the correctness of the contracts. Finally, it can generate TypeScript or Python code scaffolds with runtime checks to enforce the defined contracts. This approach brings mathematical rigor to multi-agent system development, helping catch issues at the boundaries between agents early in the process.
