@sumeru/core — Shared type definitions for Sumeru

What it does

Zero-runtime-dependency TypeScript types shared across the Sumeru monorepo. Defines the domain model for providers, models, personas, prototypes, sessions, and turn streams. This package is type-only — no functions, classes, or runtime values are exported.

Use it whenever two packages need the same shape for Host API payloads, adapter config, or session records.

API / Exports

All types are re-exported from src/types.ts:

| Category | Types | |----------|-------| | Registry | Provider, Model, Persona, Skill, Extension, Prototype | | Session | SessionInfo, SessionStatus, ExitSignal, TokenUsage | | Model config | ModelConfig, KnownProvider, CustomProvider | | Turns | Turn, AssistantTurn, ToolTurn, ToolCall | | Host config | HostConfig |

Usage example

import type { SessionInfo, Prototype, Turn } from "@sumeru/core";

function describeSession(session: SessionInfo): string {
  return `${session.id} [${session.status}] — ${session.prototype}`;
}

Workspace dependency: "@sumeru/core": "workspace:*". Version 0.3.0.
