RateLimitPolicyProtocol
Defined in the protocols module.AI Agent Protocol for gateway rate-limit / throttle admission decisions. Pure, import-free decision contract consumed by the wrapper’s admission paths. The wrapper supplies typed facts (the caller
identity, the
scope — an endpoint class, channel, or tenant token — and the current
now timestamp) and the policy decides whether the request is allowed
or limited with a retry_after_seconds hint. Concrete state and
enforcement (sliding windows, token buckets, a Redis-backed per-tenant
quota) live in the implementation; this contract keeps the decision
injectable and testable in isolation, symmetric with
:class:SendPolicyProtocol / :class:GatewayConcurrencyPolicyProtocol.
A config-driven default (:class:SlidingWindowRateLimitPolicy) is
provided for the common “N requests per window per identity” case; core
maps a limited decision onto ConnectErrorCode.RATE_LIMITED and
HelloError.retry_after_seconds.
Methods
