Crate systemprompt_wire 

Canonical AI wire types and per-protocol codecs for systemprompt.io, shared by the gateway and the agent provider clients.

The gateway speaks one provider-neutral model internally. Inbound adapters parse a client wire request into a canonical::CanonicalRequest; outbound adapters render that request to an upstream provider, parse the upstream reply into a canonical::CanonicalResponse, and map upstream SSE bytes to canonical::CanonicalEvents.

• canonical holds those provider-neutral request/response/event types.

• The per-protocol modules (anthropic, openai_chat, openai_responses, gemini) hold the codec for one wire dialect: request build, response parse, stop-reason + usage mapping, SSE-to-event translation, and auth-header construction.

• protocol names the wire dialect a provider speaks (WireProtocol), hosting the platform in front of it (Hosting), and limits the per-model token ceilings a codec clamps to (ModelLimits).

• schema holds the per-provider JSON-Schema capability matrices and the tool-schema sanitiser the codecs apply before sending.

These types are defined ONCE here and re-exported by the gateway and the agent provider clients so both layers share a single wire vocabulary. The crate depends only on systemprompt-identifiers among the workspace crates.
