read_when:
- You need to call core helpers from a plugin (TTS, STT, image gen, web search, subagent, nodes)
- You want to understand what api.runtime exposes
- You are accessing config, agent, or media helpers from plugin code
---
Reference for the `api.runtime` object injected into every plugin during registration. Use these helpers instead of importing host internals directly.
Step-by-step guide that uses these helpers in context for channel plugins.
Step-by-step guide that uses these helpers in context for provider plugins.
```typescript
register(api) {
const runtime = api.runtime;
}
```
`api.runtime.version` is the current OpenClaw product version, sourced from the shared version resolver so plugins see the same value the CLI reports.
## Config loading and writes
Prefer config that was already passed into the active call path, for example `api.config` during registration or a `cfg` argument on channel/provider callbacks. This keeps one process snapshot flowing through the work instead of reparsing config on hot paths.
Use `api.runtime.config.current()` only when a long-lived handler needs the current process snapshot and no config was passed to that function. The returned value is readonly; clone or use a mutation helper before editing.
Tool factories receive `ctx.runtimeConfig` plus `ctx.getRuntimeConfig()`. Use the getter inside a long-lived tool's `execute` callback when config can change after the tool definition was created.
Persist changes with `api.runtime.config.mutateConfigFile(...)` or `api.runtime.config.replaceConfigFile(...)`. Each write must choose an explicit `afterWrite` policy:
- `afterWrite: { mode: "auto" }` lets the gateway reload planner decide.
- `afterWrite: { mode: "restart", reason: "..." }` forces a clean restart when the writer knows hot reload is unsafe.
- `afterWrite: { mode: "none", reason: "..." }` suppresses automatic reload/restart only when the caller owns the follow-up.
The mutation helpers return `afterWrite` plus a typed `followUp` summary so callers can log or test whether they requested a restart. The gateway still owns when that restart actually happens.
`api.runtime.config.loadConfig()` and `api.runtime.config.writeConfigFile(...)` are deprecated. They warn once per plugin at runtime and remain available only for old external plugins during the migration window. Bundled plugins must not use them: an internal config boundary guard fails the build if plugin code calls them or imports those helpers from plugin SDK subpaths. Use `current()`, a passed-in `cfg`, `mutateConfigFile(...)`, or `replaceConfigFile(...)` instead.
For direct SDK imports, prefer the focused config subpaths over the broad `openclaw/plugin-sdk/config-runtime` compatibility barrel: `config-contracts` for types, `plugin-config-runtime` for already-loaded config assertions and plugin entry lookup, `runtime-config-snapshot` for current process snapshots, and `config-mutation` for writes. Bundled plugin tests should mock these focused subpaths directly instead of mocking the broad compatibility barrel.
Internal OpenClaw runtime code follows the same direction: load config once at the CLI, gateway, or process boundary, then pass that value through. Successful mutation writes refresh the process runtime snapshot and advance its internal revision; long-lived caches should key off the runtime-owned cache key instead of serializing config locally. Long-lived runtime modules have a zero-tolerance scanner for ambient `loadConfig()` calls; use a passed `cfg`, a request `context.getRuntimeConfig()`, or `getRuntimeConfig()` at an explicit process boundary.
Provider and channel execution paths must use the active runtime config snapshot, not a file snapshot returned for config readback or editing. File snapshots preserve source values such as SecretRef markers for UI and writes; provider callbacks need the resolved runtime view. When a helper may be called with either the active source snapshot or the active runtime snapshot, route through `selectApplicableRuntimeConfig()` before reading credentials.
## Reusable runtime utilities
Use inbound `botLoopProtection` facts for bot-authored inbound messages. Core applies the shared in-memory sliding-window guard before session record and dispatch, without tying the policy to one channel. The guard tracks `(scopeId, conversationId, participant pair)` keys, counts both directions of a pair together, applies a cooldown once the window budget is exceeded, and prunes inactive entries opportunistically.
Channel plugins that expose this behavior to operators should prefer the shared `channels.defaults.botLoopProtection` shape for baseline budgets, then layer channel/provider-specific overrides on top. The shared config uses seconds because it is user-facing:
```typescript
type ChannelBotLoopProtectionConfig = {
enabled?: boolean;
maxEventsPerWindow?: number;
windowSeconds?: number;
cooldownSeconds?: number;
};
```
Pass normalized bot-pair facts with the resolved turn. Core resolves defaults, unit conversion, and `enabled` semantics:
```typescript
return {
channel: "example",
routeSessionKey,
storePath,
ctxPayload,
recordInboundSession,
runDispatch,
botLoopProtection: {
scopeId: "account-1",
conversationId: "channel-1",
senderId: "bot-a",
receiverId: "bot-b",
config: channelConfig.botLoopProtection,
defaultsConfig: runtimeConfig.channels?.defaults?.botLoopProtection,
defaultEnabled: allowBotsMode !== "off",
},
};
```
Use `openclaw/plugin-sdk/pair-loop-guard-runtime` directly only for custom
two-party event loops that do not go through the shared inbound reply runner.
## Runtime namespaces
Agent identity, directories, and session management.
```typescript
// Resolve the agent's working directory (agentId is required)
const agentDir = api.runtime.agent.resolveAgentDir(cfg, agentId);
// Resolve agent workspace
const workspaceDir = api.runtime.agent.resolveAgentWorkspaceDir(cfg, agentId);
// Get agent identity
const identity = api.runtime.agent.resolveAgentIdentity(cfg);
// Get default thinking level
const thinking = api.runtime.agent.resolveThinkingDefault({
cfg,
provider,
model,
});
// Validate a user-provided thinking level against the active provider profile
const policy = api.runtime.agent.resolveThinkingPolicy({ provider, model });
const level = api.runtime.agent.normalizeThinkingLevel("extra high");
if (level && policy.levels.some((entry) => entry.id === level)) {
// pass level to an embedded run
}
// Get agent timeout
const timeoutMs = api.runtime.agent.resolveAgentTimeoutMs(cfg);
// Ensure workspace exists
await api.runtime.agent.ensureAgentWorkspace(cfg);
// Run an embedded agent turn
const result = await api.runtime.agent.runEmbeddedAgent({
sessionId: "my-plugin:task-1",
runId: crypto.randomUUID(),
workspaceDir: api.runtime.agent.resolveAgentWorkspaceDir(cfg, agentId),
prompt: "Summarize the latest changes",
timeoutMs: api.runtime.agent.resolveAgentTimeoutMs(cfg),
});
```
`runEmbeddedAgent(...)` is the neutral helper for starting a normal OpenClaw agent turn from plugin code. It uses the same provider/model resolution and agent-harness selection as channel-triggered replies.
`runEmbeddedPiAgent(...)` remains as a deprecated compatibility alias for existing plugins. New code should use `runEmbeddedAgent(...)`.
`resolveThinkingPolicy(...)` returns the provider/model's supported thinking levels and optional default. Provider plugins own the model-specific profile through their thinking hooks, so tool plugins should call this runtime helper instead of importing or duplicating provider lists.
`normalizeThinkingLevel(...)` converts user text such as `on`, `x-high`, or `extra high` to the canonical stored level before checking it against the resolved policy.
**Session store helpers** are under `api.runtime.agent.session`:
```typescript
const entry = api.runtime.agent.session.getSessionEntry({ agentId, sessionKey });
for (const { sessionKey, entry } of api.runtime.agent.session.listSessionEntries({ agentId })) {
// Iterate session rows without depending on the legacy sessions.json shape.
}
await api.runtime.agent.session.patchSessionEntry({
agentId,
sessionKey,
update: (entry) => ({ thinkingLevel: "high" }),
});
const storePath = api.runtime.agent.session.resolveStorePath(cfg.session?.store, { agentId });
await api.runtime.agent.session.runWithWorkAdmission(
{ storePath, sessionKey },
async (signal) => {
// Create or update the session, then pass signal to the admitted agent run.
},
);
```
Prefer `getSessionEntry(...)`, `listSessionEntries(...)`, `patchSessionEntry(...)`, or `upsertSessionEntry(...)` for session workflows. These helpers address sessions by agent/session identity so plugins do not depend on the legacy `sessions.json` storage shape. Use `preserveActivity: true` for metadata-only patches that should not refresh session activity, and `replaceEntry: true` only when the callback returns a complete entry and deleted fields must stay deleted.
Use `runWithWorkAdmission(...)` when a plugin starts work on a persisted session. The callback rejects archived or concurrently replaced sessions, keeps archive/reset/delete mutations coordinated through completion, and receives an `AbortSignal` that must be forwarded to the agent run.
For transcript reads and writes, import `openclaw/plugin-sdk/session-transcript-runtime` and use `resolveSessionTranscriptIdentity(...)`, `resolveSessionTranscriptTarget(...)`, `readSessionTranscriptEvents(...)`, `appendSessionTranscriptMessageByIdentity(...)`, `publishSessionTranscriptUpdateByIdentity(...)`, or `withSessionTranscriptWriteLock(...)` with `{ agentId, sessionKey, sessionId }`. These APIs let plugins identify a transcript, read its events, append messages, publish updates, and run related operations under the same transcript write lock. Passing `sessionFile`, using `resolveSessionTranscriptLegacyFileTarget(...)`, or importing low-level `appendSessionTranscriptMessage(...)` / `emitSessionTranscriptUpdate(...)` from `openclaw/plugin-sdk/agent-harness-runtime` is deprecated; those paths exist only for legacy code that already receives an active transcript artifact.
`resolveStorePath(...)` and `updateSessionStoreEntry(...)` round out the session helpers: `resolveStorePath` resolves the session store path for a given scope, and `updateSessionStoreEntry({ storePath, sessionKey, update })` patches one entry directly by store path when the caller already knows it.
`loadSessionStore(...)`, `saveSessionStore(...)`, `updateSessionStore(...)`, and `resolveSessionFilePath(...)` are deprecated compatibility helpers for plugins that still intentionally depend on the legacy whole-store or transcript-file shape. New plugin code must not use those helpers, and existing callers should migrate to entry helpers and transcript identity helpers.
Default model and provider constants:
```typescript
const model = api.runtime.agent.defaults.model; // e.g. "gpt-5.5"
const provider = api.runtime.agent.defaults.provider; // e.g. "openai"
```
Run a host-owned text completion without importing provider internals or
duplicating OpenClaw model/auth/base URL preparation.
```typescript
const result = await api.runtime.llm.complete({
messages: [{ role: "user", content: "Summarize this transcript." }],
purpose: "my-plugin.summary",
maxTokens: 512,
temperature: 0.2,
});
```
The helper uses the same simple-completion preparation path as OpenClaw's
built-in runtime and the host-owned runtime config snapshot. Context engines
receive a session-bound `llm.complete` capability, so model calls use the
active session's agent and do not silently fall back to the default agent. The
result includes provider/model/agent attribution plus normalized token,
cache, and estimated cost usage when available.
Model overrides require operator opt-in via `plugins.entries..llm.allowModelOverride: true` in config. Use `plugins.entries..llm.allowedModels` to restrict trusted plugins to specific canonical `provider/model` targets. Cross-agent completions require `plugins.entries..llm.allowAgentIdOverride: true`.
Launch and manage background subagent runs.
```typescript
// 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-5.5", // 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",
});
```
Model overrides (`provider`/`model`) require operator opt-in via `plugins.entries..subagent.allowModelOverride: true` in config. Untrusted plugins can still run subagents, but override requests are rejected.
`deleteSession(...)` can delete sessions created by the same plugin through `api.runtime.subagent.run(...)`. Deleting arbitrary user or operator sessions still requires an admin-scoped Gateway request.
List connected nodes and invoke a node-host command from Gateway-loaded plugin code or from plugin CLI commands. Use this when a plugin owns local work on a paired device, for example a browser or audio bridge on another Mac.
```typescript
const { nodes } = await api.runtime.nodes.list({ connected: true });
const result = await api.runtime.nodes.invoke({
nodeId: "mac-studio",
command: "my-plugin.command",
params: { action: "start" },
timeoutMs: 30000,
});
```
Inside the Gateway this runtime is in-process. In plugin CLI commands it calls the configured Gateway over RPC, so commands such as `openclaw googlemeet recover-tab` can inspect paired nodes from the terminal. Node commands still go through normal Gateway node pairing, command allowlists, plugin node-invoke policies, and node-local command handling.
Plugins that expose dangerous node-host commands should register a node-invoke policy with `api.registerNodeInvokePolicy(...)`. The policy runs in the Gateway after command allowlist checks and before the command is forwarded to the node, so direct `node.invoke` calls and higher-level plugin tools share the same enforcement path.
The optional `scopes` field requests Gateway operator scopes for the invocation. OpenClaw honors it only for bundled plugins and trusted official plugin installations; requests from other plugins do not elevate the call. Use it only when a trusted plugin must invoke a node command with a stricter Gateway scope, such as `operator.admin`.
Bind Task Flow and Task Run state to an existing OpenClaw session key or trusted tool context.
- `api.runtime.tasks.managedFlows` is mutation-capable: create, advance, and cancel Task Flows.
- `api.runtime.tasks.flows` and `api.runtime.tasks.runs` are read-only DTO views for listing and status lookups; both expose `bindSession(...)` / `fromToolContext(...)` plus `get`, `list`, `findLatest`, and `resolve`.
- `api.runtime.tasks.flow` is a deprecated alias for `managedFlows`.
Task Flow tracks durable multi-step workflow state. It is not a scheduler:
use Cron or `api.session.workflow.scheduleSessionTurn(...)` for future
wakeups, then use `managedFlows` from the scheduled turn when that work
needs flow state, child tasks, waits, or cancellation.
```typescript
const taskFlow = api.runtime.tasks.managedFlows.fromToolContext(ctx);
const created = taskFlow.createManaged({
controllerId: "my-plugin/review-batch",
goal: "Review new pull requests",
});
const child = taskFlow.runTask({
flowId: created.flowId,
runtime: "acp",
childSessionKey: "agent:main:subagent:reviewer",
task: "Review PR #123",
status: "running",
startedAt: Date.now(),
});
const waiting = taskFlow.setWaiting({
flowId: created.flowId,
expectedRevision: created.revision,
currentStep: "await-human-reply",
waitJson: { kind: "reply", channel: "telegram" },
});
```
Use `bindSession({ sessionKey, requesterOrigin })` when you already have a trusted OpenClaw session key from your own binding layer. Do not bind from raw user input.
Text-to-speech synthesis.
```typescript
// 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,
});
```
Uses core `messages.tts` configuration and provider selection. Returns PCM audio buffer + sample rate. `textToSpeechStream` is also available for streaming synthesis.
Image, audio, and video analysis.
```typescript
// 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,
});
// Structured image extraction through a specific provider/model.
// Include at least one image; text inputs are supplemental context.
const evidence = await api.runtime.mediaUnderstanding.extractStructuredWithModel({
provider: "codex",
model: "gpt-5.5",
input: [
{
type: "image",
buffer: receiptImageBuffer,
fileName: "receipt.png",
mime: "image/png",
},
{ type: "text", text: "Prefer the printed total over handwritten notes." },
],
instructions: "Extract vendor, total, and searchable tags.",
schemaName: "receipt.evidence",
jsonSchema: {
type: "object",
properties: {
vendor: { type: "string" },
total: { type: "number" },
tags: { type: "array", items: { type: "string" } },
},
required: ["vendor", "total"],
},
cfg: api.config,
});
```
Returns `{ text: undefined }` when no output is produced (e.g. skipped input).
`describeImageFileWithModel(...)` describes an already-known image through a specific provider/model, bypassing the default active-model resolution that `describeImageFile(...)` uses.
`api.runtime.stt.transcribeAudioFile(...)` remains as a compatibility alias for `api.runtime.mediaUnderstanding.transcribeAudioFile(...)`.
Image generation.
```typescript
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 });
```
Video generation, mirroring the image generation shape.
```typescript
const result = await api.runtime.videoGeneration.generate({
prompt: "A drone shot flying over a coastline at sunrise",
cfg: api.config,
});
const providers = api.runtime.videoGeneration.listProviders({ cfg: api.config });
```
Music generation, mirroring the image generation shape.
```typescript
const result = await api.runtime.musicGeneration.generate({
prompt: "An upbeat lo-fi track for a coding session",
cfg: api.config,
});
const providers = api.runtime.musicGeneration.listProviders({ cfg: api.config });
```
Web search.
```typescript
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 },
});
```
Low-level media utilities.
```typescript
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 });
const terminalQr = await api.runtime.media.renderQrTerminal("https://openclaw.ai");
const pngQr = await api.runtime.media.renderQrPngBase64("https://openclaw.ai", {
scale: 6, // 1-12
marginModules: 4, // 0-16
});
const pngQrDataUrl = await api.runtime.media.renderQrPngDataUrl("https://openclaw.ai");
const tmpRoot = resolvePreferredOpenClawTmpDir();
const pngQrFile = await api.runtime.media.writeQrPngTempFile("https://openclaw.ai", {
tmpRoot,
dirPrefix: "my-plugin-qr-",
fileName: "qr.png",
});
```
Current runtime config snapshot and transactional config writes. Prefer
config that was already passed into the active call path; use
`current()` only when the handler needs the process snapshot directly.
```typescript
const cfg = api.runtime.config.current();
await api.runtime.config.mutateConfigFile({
afterWrite: { mode: "auto" },
mutate(draft) {
draft.plugins ??= {};
},
});
```
`mutateConfigFile(...)` and `replaceConfigFile(...)` return a `followUp`
value, for example `{ mode: "restart", requiresRestart: true, reason }`,
which records the writer intent without taking restart control away from the
gateway.
System-level utilities.
```typescript
await api.runtime.system.enqueueSystemEvent(event);
api.runtime.system.requestHeartbeat({
source: "other",
intent: "event",
reason: "plugin-event",
});
api.runtime.system.requestHeartbeatNow({ reason: "plugin-event" }); // Deprecated compatibility alias.
const heartbeatResult = await api.runtime.system.runHeartbeatOnce({
reason: "plugin-triggered-check",
});
const output = await api.runtime.system.runCommandWithTimeout(cmd, args, opts);
const hint = api.runtime.system.formatNativeDependencyHint(pkg);
```
`runHeartbeatOnce(...)` runs a single heartbeat cycle immediately, bypassing the normal coalesce timer. Pass `{ heartbeat: { target: "last" } }` to force delivery to the last active channel instead of the default `target: "none"` suppression.
`runCommandWithTimeout(...)` returns captured `stdout` and `stderr`, optional
truncation counts, `code`, `signal`, `killed`, `termination`, and
`noOutputTimedOut`. Timeout and no-output-timeout results report `code: 124`
when the child process does not provide a non-zero exit code. Non-timeout
signal exits can still return `code: null`, so use `termination` and
`noOutputTimedOut` to distinguish timeout reasons.
Event subscriptions.
```typescript
api.runtime.events.onAgentEvent((event) => {
/* ... */
});
api.runtime.events.onSessionTranscriptUpdate((update) => {
/* ... */
});
```
Logging.
```typescript
const verbose = api.runtime.logging.shouldLogVerbose();
const childLogger = api.runtime.logging.getChildLogger({ plugin: "my-plugin" }, { level: "debug" });
```
Model and provider auth resolution.
```typescript
const auth = await api.runtime.modelAuth.getApiKeyForModel({ model, cfg });
// Request-ready auth, including provider runtime exchanges (e.g. OAuth refresh)
const runtimeAuth = await api.runtime.modelAuth.getRuntimeAuthForModel({ model, cfg });
const providerAuth = await api.runtime.modelAuth.resolveApiKeyForProvider({
provider: "openai",
cfg,
});
```
State directory resolution and SQLite-backed keyed storage.
```typescript
const stateDir = api.runtime.state.resolveStateDir(process.env);
const store = api.runtime.state.openKeyedStore({
namespace: "my-feature",
maxEntries: 200,
defaultTtlMs: 15 * 60_000,
});
await store.register("key-1", { value: "hello" });
const claimed = await store.registerIfAbsent("dedupe-key", { value: "first" });
const value = await store.lookup("key-1");
await store.consume("key-1");
await store.clear();
```
Keyed stores survive restarts and are isolated by the runtime-bound plugin id. Use `registerIfAbsent(...)` for atomic dedupe claims: it returns `true` when the key was missing or expired and registered, or `false` when a live value already exists without overwriting its value, creation time, or TTL. Limits: `maxEntries` per namespace, 50,000 live rows per plugin, JSON values under 64KB, and optional TTL expiry. When a write would exceed the plugin row cap, the runtime sheds the oldest live rows from the namespace being written; sibling namespaces are not evicted for that write, and the write still fails if the namespace cannot free enough rows.
`openSyncKeyedStore(...)` returns the same store shape with synchronous methods (`register`, `registerIfAbsent`, `lookup`, `consume`, `clear` all return values directly instead of promises) for callers that cannot await.
`openChannelIngressQueue(...)` opens a persisted ingress queue scoped to the calling plugin, for buffering inbound events that need at-least-once processing across restarts.
`openKeyedStore`, `openSyncKeyedStore`, and `openChannelIngressQueue` are available only to bundled plugins and trusted official plugin installations in this release.
Channel-specific runtime helpers (available when a channel plugin is loaded). Grouped by concern:
| Group | Purpose |
| --- | --- |
| `text` | Chunking (`chunkText`, `chunkMarkdownText`, `resolveChunkMode`), control-command detection, Markdown table conversion. |
| `reply` | Buffered-block reply dispatch, envelope formatting, effective messages/human-delay config resolution. |
| `routing` | `buildAgentSessionKey`, `resolveAgentRoute`. |
| `pairing` | `buildPairingReply`, allowlist reads, pairing-request upserts. |
| `media` | Remote media download/save (see below). |
| `activity` | Record/read last channel activity. |
| `session` | Session metadata from inbound events, last-route updates. |
| `mentions` | Mention-policy helpers (see below). |
| `reactions` | Ack-reaction handles for in-flight processing indicators. |
| `groups` | Group policy and require-mention resolution. |
| `debounce` | Inbound message debouncing. |
| `commands` | Command authorization and text-command gating. |
| `outbound` | Load a channel's outbound adapter. |
| `inbound` | Build inbound event context and run the shared inbound-event/reply kernel. |
| `threadBindings` | Adjust idle-timeout/max-age for bound session threads. |
| `runtimeContexts` | Register, read, and watch process-local per-channel/account/capability context. |
`api.runtime.channel.media` is the preferred surface for channel media downloads and storage:
```typescript
const saved = await api.runtime.channel.media.saveRemoteMedia({
url,
subdir: "inbound",
maxBytes,
filePathHint: fileName,
});
```
Use `saveRemoteMedia(...)` when a remote URL should become OpenClaw media. Use `saveResponseMedia(...)` when the plugin already fetched a `Response` with plugin-owned auth, redirect, or allowlist handling. Use `readRemoteMediaBuffer(...)` only when the plugin needs raw bytes for inspection, transforms, decryption, or reupload. `fetchRemoteMedia(...)` remains a deprecated compatibility alias for `readRemoteMediaBuffer(...)`.
`api.runtime.channel.mentions` is the shared inbound mention-policy surface for bundled channel plugins that use runtime injection:
```typescript
const mentionMatch = api.runtime.channel.mentions.matchesMentionWithExplicit(text, {
mentionRegexes,
mentionPatterns,
});
const decision = api.runtime.channel.mentions.resolveInboundMentionDecision({
facts: {
canDetectMention: true,
wasMentioned: mentionMatch.matched,
implicitMentionKinds: api.runtime.channel.mentions.implicitMentionKindWhen(
"reply_to_bot",
isReplyToBot,
),
},
policy: {
isGroup,
requireMention,
allowTextCommands,
hasControlCommand,
commandAuthorized,
},
});
```
Available mention helpers:
- `buildMentionRegexes`
- `matchesMentionPatterns`
- `matchesMentionWithExplicit`
- `implicitMentionKindWhen`
- `resolveInboundMentionDecision`
`api.runtime.channel.mentions` intentionally does not expose the older `resolveMentionGating*` compatibility helpers. Prefer the normalized `{ facts, policy }` path.
Several fields under `reply`, `session`, and `inbound` carry per-field `@deprecated` notes pointing at the current channel-turn kernel or channel-outbound adapters; check the inline JSDoc on the specific helper before building new code on it.
## Storing runtime references
Use `createPluginRuntimeStore` to store the runtime reference for use outside the `register` callback:
```typescript
import { createPluginRuntimeStore } from "openclaw/plugin-sdk/runtime-store";
import type { PluginRuntime } from "openclaw/plugin-sdk/runtime-store";
const store = createPluginRuntimeStore({
pluginId: "my-plugin",
errorMessage: "my-plugin runtime not initialized",
});
```
```typescript
export default defineChannelPluginEntry({
id: "my-plugin",
name: "My Plugin",
description: "Example",
plugin: myPlugin,
setRuntime: store.setRuntime,
});
```
```typescript
export function getRuntime() {
return store.getRuntime(); // throws if not initialized
}
export function tryGetRuntime() {
return store.tryGetRuntime(); // returns null if not initialized
}
```
Prefer `pluginId` for the runtime-store identity. The lower-level `key` form is for uncommon cases where one plugin intentionally needs more than one runtime slot.
## Other top-level `api` fields
Beyond `api.runtime`, the API object also provides:
Plugin id.
Plugin display name.
Current config snapshot (active in-memory runtime snapshot when available).
Plugin-specific config from `plugins.entries..config`.
Scoped logger (`debug`, `info`, `warn`, `error`).
Current load mode: `"full"` (live activation), `"discovery"` / `"tool-discovery"` (read-only capability discovery), `"setup-only"` (lightweight setup entry), `"setup-runtime"` (setup flow that also needs the runtime channel entry), or `"cli-metadata"` (CLI command metadata collection).
Resolve a path relative to the plugin root.
