@soda_game/orbit-provider-core

Runtime-neutral provider request and response normalization for Orbit hosts.

The zero-dependency package contains provider profiles, request and response conversion, model discovery, retries, reasoning-state replay, normalized token usage, and resumable media jobs. Credential storage, OAuth, billing, pricing, prompts, skills, UI, and deployment remain in host adapters.

Provider requests consume the canonical per-item projection produced by @soda_game/orbit-agent-core. Chat Completions and Responses payloads are rebuilt from protocol allowlists: host paths, Session metadata, local media references, and internal compaction markers never become wire fields. Image parts must already be resolved to a provider-supported, bounded transport by the host; unresolved local paths fail closed.

maxOutputTokens is optional. Explicit, capability-checked values are sent to the selected provider, while an omitted value remains omitted so an unknown BYOK model can apply its native policy instead of inheriting an incompatible Orbit product limit.

Successful assistant responses may include normalized prompt, completion, reasoning, cached, and total token counts. Provider-specific raw cost fields are intentionally omitted so each host can apply its own trusted billing policy.
