@cra-agent/policy

Spend control for an agent that pays. A pure function: give it the policy and the facts, get back allow or the rule that refused. No I/O, no clock, easy to test.

npm i @cra-agent/policy

import { evaluatePolicy, parsePolicyString } from "@cra-agent/policy";

const policy = parsePolicyString("daily=5,per_seller=0.5,per_payment=0.05,rate=120/60s,deny=evil.example");
const decision = evaluatePolicy(policy, ctx); // { allow: true } or { allow: false, rule, reason }

| Key | Meaning | |---|---| | daily | USDC per rolling day | | per_seller | USDC per day to one counterparty | | per_payment | USDC for a single payment | | rate | 120/60s: payments per window | | allow / deny | Hosts or addresses separated by \|. allow=* lifts the allowlist. | | networks | CAIP-2 ids the agent may pay on | | identity | required to pay only ERC-8004 verified sellers | | bond | Minimum seller bond |

Unknown keys are an error, not a silent default. Amounts are Usdc6 from @cra-agent/accounting, never floats.
