Crate agentcontract 

agentcontract

Rust implementation of the AgentContract specification.

Behavioral contracts for AI agents — declare what an agent must, must not, and can do, enforced on every run.

Quick Start

use agentcontract::{load_contract, ContractRunner, RunContext};

let contract = load_contract("my-agent.contract.yaml").unwrap();
let runner = ContractRunner::new(contract);

let ctx = RunContext {
    input: "What are the GxP requirements?".into(),
    output: "Per 21 CFR Part 211...".into(),
    duration_ms: 1200.0,
    ..Default::default()
};

let result = runner.run(&ctx);
if !result.passed {
    for v in result.blocking_violations() {
        eprintln!("[{}] {}: {}", v.action_taken, v.clause_name, v.details);
    }
}
