插件运行时辅助程序
注入到每个插件中的 api.runtime 对象的参考。请使用这些辅助程序,而不是直接导入主机内部组件。
register(api) {
const runtime = api.runtime;
}
运行时命名空间
api.runtime.agent
Agent 身份、目录和会话管理。
// Resolve the agent's working directory
const agentDir = api.runtime.agent.resolveAgentDir(cfg);
// Resolve agent workspace
const workspaceDir = api.runtime.agent.resolveAgentWorkspaceDir(cfg);
// Get agent identity
const identity = api.runtime.agent.resolveAgentIdentity(cfg);
// Get default thinking level
const thinking = api.runtime.agent.resolveThinkingDefault(cfg, provider, model);
// Get agent timeout
const timeoutMs = api.runtime.agent.resolveAgentTimeoutMs(cfg);
// Ensure workspace exists
await api.runtime.agent.ensureAgentWorkspace(cfg);
// Run an embedded Pi agent
const agentDir = api.runtime.agent.resolveAgentDir(cfg);
const result = await api.runtime.agent.runEmbeddedPiAgent({
sessionId: "my-plugin:task-1",
runId: crypto.randomUUID(),
sessionFile: path.join(agentDir, "sessions", "my-plugin-task-1.jsonl"),
workspaceDir: api.runtime.agent.resolveAgentWorkspaceDir(cfg),
prompt: "Summarize the latest changes",
timeoutMs: api.runtime.agent.resolveAgentTimeoutMs(cfg),
});
会话存储辅助程序 位于 api.runtime.agent.session 下:
const storePath = api.runtime.agent.session.resolveStorePath(cfg);
const store = api.runtime.agent.session.loadSessionStore(cfg);
await api.runtime.agent.session.saveSessionStore(cfg, store);
const filePath = api.runtime.agent.session.resolveSessionFilePath(cfg, sessionId);
api.runtime.agent.defaults
默认模型和提供商常量:
const model = api.runtime.agent.defaults.model; // e.g. "anthropic/claude-sonnet-4-6"
const provider = api.runtime.agent.defaults.provider; // e.g. "anthropic"
api.runtime.subagent
启动和管理后台子代理运行。
// Start a subagent run
const { runId } = await api.runtime.subagent.run({
sessionKey: "agent:main:subagent:search-helper",
message: "Expand this query into focused follow-up searches.",
provider: "openai", // optional override
model: "gpt-4.1-mini", // optional override
deliver: false,
});
// Wait for completion
const result = await api.runtime.subagent.waitForRun({ runId, timeoutMs: 30000 });
// Read session messages
const { messages } = await api.runtime.subagent.getSessionMessages({
sessionKey: "agent:main:subagent:search-helper",
limit: 10,
});
// Delete a session
await api.runtime.subagent.deleteSession({
sessionKey: "agent:main:subagent:search-helper",
});
模型覆盖 (provider/model) 需要操作员通过配置中的
plugins.entries.<id>.subagent.allowModelOverride: true 选择加入。
不受信任的插件仍可运行子代理,但覆盖请求将被拒绝。
api.runtime.tts
文本转语音合成。
// Standard TTS
const clip = await api.runtime.tts.textToSpeech({
text: "Hello from OpenClaw",
cfg: api.config,
});
// Telephony-optimized TTS
const telephonyClip = await api.runtime.tts.textToSpeechTelephony({
text: "Hello from OpenClaw",
cfg: api.config,
});
// List available voices
const voices = await api.runtime.tts.listVoices({
provider: "elevenlabs",
cfg: api.config,
});
使用核心 messages.tts 配置和提供商选择。返回 PCM 音频缓冲区 + 采样率。
图像、音频和视频分析。
// Describe an image
const image = await api.runtime.mediaUnderstanding.describeImageFile({
filePath: "/tmp/inbound-photo.jpg",
cfg: api.config,
agentDir: "/tmp/agent",
});
// Transcribe audio
const { text } = await api.runtime.mediaUnderstanding.transcribeAudioFile({
filePath: "/tmp/inbound-audio.ogg",
cfg: api.config,
mime: "audio/ogg", // optional, for when MIME cannot be inferred
});
// Describe a video
const video = await api.runtime.mediaUnderstanding.describeVideoFile({
filePath: "/tmp/inbound-video.mp4",
cfg: api.config,
});
// Generic file analysis
const result = await api.runtime.mediaUnderstanding.runFile({
filePath: "/tmp/inbound-file.pdf",
cfg: api.config,
});
当未产生输出时(例如跳过输入),返回 { text: undefined }。
api.runtime.stt.transcribeAudioFile(...) 保留为
api.runtime.mediaUnderstanding.transcribeAudioFile(...) 的兼容性别名。
api.runtime.imageGeneration
图像生成。
const result = await api.runtime.imageGeneration.generate({
prompt: "A robot painting a sunset",
cfg: api.config,
});
const providers = api.runtime.imageGeneration.listProviders({ cfg: api.config });
api.runtime.webSearch
Web 搜索。
const providers = api.runtime.webSearch.listProviders({ config: api.config });
const result = await api.runtime.webSearch.search({
config: api.config,
args: { query: "OpenClaw plugin SDK", count: 5 },
});
低级媒体实用程序。
const webMedia = await api.runtime.media.loadWebMedia(url);
const mime = await api.runtime.media.detectMime(buffer);
const kind = api.runtime.media.mediaKindFromMime("image/jpeg"); // "image"
const isVoice = api.runtime.media.isVoiceCompatibleAudio(filePath);
const metadata = await api.runtime.media.getImageMetadata(filePath);
const resized = await api.runtime.media.resizeToJpeg(buffer, { maxWidth: 800 });
api.runtime.config
配置加载和写入。
const cfg = await api.runtime.config.loadConfig();
await api.runtime.config.writeConfigFile(cfg);
api.runtime.system
系统级实用程序。
await api.runtime.system.enqueueSystemEvent(event);
api.runtime.system.requestHeartbeatNow();
const output = await api.runtime.system.runCommandWithTimeout(cmd, args, opts);
const hint = api.runtime.system.formatNativeDependencyHint(pkg);
api.runtime.events
事件订阅。
api.runtime.events.onAgentEvent((event) => {
/* ... */
});
api.runtime.events.onSessionTranscriptUpdate((update) => {
/* ... */
});
api.runtime.logging
日志记录。
const verbose = api.runtime.logging.shouldLogVerbose();
const childLogger = api.runtime.logging.getChildLogger({ plugin: "my-plugin" }, { level: "debug" });
api.runtime.modelAuth
模型和提供商身份验证解析。
const auth = await api.runtime.modelAuth.getApiKeyForModel({ model, cfg });
const providerAuth = await api.runtime.modelAuth.resolveApiKeyForProvider({
provider: "openai",
cfg,
});
api.runtime.state
状态目录解析。
const stateDir = api.runtime.state.resolveStateDir();
Memory 工具工厂和 CLI。
const getTool = api.runtime.tools.createMemoryGetTool(/* ... */);
const searchTool = api.runtime.tools.createMemorySearchTool(/* ... */);
api.runtime.tools.registerMemoryCli(/* ... */);
api.runtime.channel
特定的渠道运行时助手(在加载渠道插件时可用)。
存储运行时引用
使用 createPluginRuntimeStore 存储运行时引用,以便在 register 回调之外使用:
import { createPluginRuntimeStore } from "openclaw/plugin-sdk/runtime-store";
import type { PluginRuntime } from "openclaw/plugin-sdk/runtime-store";
const store = createPluginRuntimeStore<PluginRuntime>("my-plugin runtime not initialized");
// In your entry point
export default defineChannelPluginEntry({
id: "my-plugin",
name: "My Plugin",
description: "Example",
plugin: myPlugin,
setRuntime: store.setRuntime,
});
// In other files
export function getRuntime() {
return store.getRuntime(); // throws if not initialized
}
export function tryGetRuntime() {
return store.tryGetRuntime(); // returns null if not initialized
}
其他顶层 api 字段
除了 api.runtime,API 对象还提供:
| 字段 | 类型 | 描述 |
|---|
api.id | string | 插件 ID |
api.name | string | 插件显示名称 |
api.config | OpenClawConfig | 当前配置快照 |
api.pluginConfig | Record<string, unknown> | 来自 plugins.entries.<id>.config 的插件特定配置 |
api.logger | PluginLogger | 作用域记录器 (debug, info, warn, error) |
api.registrationMode | PluginRegistrationMode | "full"、"setup-only" 或 "setup-runtime" |
api.resolvePath(input) | (string) => string | 解析相对于插件根目录的路径 |
