[experimental] @coohu/core

@coohu/core is the stateful orchestration layer of the Cline SDK. It connects the agent runtime, provider settings, storage, default tools, and session lifecycle into a host-ready runtime.

What You Get

• session lifecycle and orchestration primitives
• provider settings and account services
• default runtime tools and MCP integration
• storage-backed session and team state helpers
• host-facing Node helpers through @coohu/core

Installation

npm install @coohu/core

Entry Points

• @coohu/core: core contracts, shared utilities, and Node/server helpers for building hosts and runtimes

Typical Usage

Most host apps should start with @coohu/core.

import { ClineCore } from "@coohu/core";

const cline = await ClineCore.create({});

const result = await cline.start({
	config: {
		providerId: "anthropic",
		modelId: "claude-sonnet-4-6",
		apiKey: process.env.ANTHROPIC_API_KEY ?? "",
		cwd: process.cwd(),
		mode: "act",
		enableTools: true,
		enableSpawnAgent: false,
		enableAgentTeams: false,
		systemPrompt: "You are a concise assistant.",
	},
	prompt: "Summarize this project.",
	interactive: false,
});

console.log(result.result?.text);
await cline.dispose();

Session Bootstrap

ClineCore.create(...) also accepts prepare(input).

Use it when a host needs to prepare workspace-scoped runtime state before each session starts, then apply watcher/extensions/telemetry inputs through explicit localRuntime bootstrap fields without widening the shared host contract.

Main APIs

Runtime and Sessions

Use @coohu/core for host-facing runtime assembly:

• ClineCore.create(...)
• createRuntimeHost(...)
• LocalRuntimeHost
• HubRuntimeHost and RemoteRuntimeHost
• DefaultRuntimeBuilder

ClineCore is the app-facing session API. The lower-level RuntimeHost boundary uses runtime-primitive names such as startSession and runTurn so transport adapters stay distinct from product methods like start and send. Service-style operations such as pending prompt edits, accumulated usage lookup, and active-session model switching are exposed through ClineCore when the selected transport supports them rather than being part of the minimal host primitive vocabulary.

Default Tools

@coohu/core owns the built-in host tools and executors:

• createBuiltinTools(...)
• createDefaultTools(...)
• createDefaultExecutors(...)

Storage and Settings

The package also exports storage and settings helpers such as:

• ProviderSettingsManager
• CoreSettingsService and createCoreSettingsService
• MCP settings helpers such as setMcpServerDisabled
• SqliteTeamStore
• SQLite-backed local session stores and artifacts through @coohu/core
