Most common types are exported from @cline/shared; runtime entry-point packages re-export selected helpers.

​
AgentRuntime Types

import type {
  AgentMessage,
  AgentMessagePart,
  AgentRunResult,
  AgentRuntimeEvent,
  AgentRuntimeStateSnapshot,
  AgentUsage,
} from "@cline/sdk"
AgentRunResult is returned by direct AgentRuntime / Agent runs: 
interface AgentRunResult {
  agentId: string
  agentRole?: string
  runId: string
  status: "completed" | "aborted" | "failed"
  iterations: number
  outputText: string
  messages: readonly AgentMessage[]
  usage: AgentUsage
  error?: Error
}

​
Host-Facing Agent Types

import type {
  AgentConfig,
  AgentEvent,
  AgentResult,
  AgentPlugin,
  AgentTool,
  AgentToolContext,
  ToolPolicy,
} from "@cline/sdk"
AgentResult is the host/core-facing result shape: 
interface AgentResult {
  text: string
  usage: LegacyAgentUsage
  messages: MessageWithMetadata[]
  toolCalls: ToolCallRecord[]
  iterations: number
  finishReason: "completed" | "max_iterations" | "aborted" | "mistake_limit" | "error"
  model: { id: string; provider: string; info?: ModelInfo }
  startedAt: Date
  endedAt: Date
  durationMs: number
}

​
ClineCore Types

import type {
  ClineCoreOptions,
  ClineCoreStartInput,
  CoreSessionConfig,
  SessionRecord,
} from "@cline/sdk"

​
Tool Types

interface ToolPolicy {
  enabled?: boolean
  autoApprove?: boolean
