summary: "Plugin hooks: intercept agent, tool, message, session, and Gateway lifecycle events"
title: "Plugin hooks"
read_when:
  - You are building a plugin that needs before_tool_call, before_agent_reply, message hooks, or lifecycle hooks
  - You need to block, rewrite, or require approval for tool calls from a plugin
  - You are deciding between internal hooks and plugin hooks
---

Plugin hooks are in-process extension points for OpenClaw plugins. Use them
when a plugin needs to inspect or change agent runs, tool calls, message flow,
session lifecycle, subagent routing, installs, or Gateway startup.

Use [internal hooks](/automation/hooks) instead when you want a small
operator-installed `HOOK.md` script for command and Gateway events such as
`/new`, `/reset`, `/stop`, `agent:bootstrap`, or `gateway:startup`.

## Quick start

Register typed plugin hooks with `api.on(...)` from your plugin entry:

```typescript
import { definePluginEntry } from "openclaw/plugin-sdk/plugin-entry";

export default definePluginEntry({
  id: "tool-preflight",
  name: "Tool Preflight",
  register(api) {
    api.on(
      "before_tool_call",
      async (event) => {
        if (event.toolName !== "web_search") {
          return;
        }

        return {
          requireApproval: {
            title: "Run web search",
            description: `Allow search query: ${String(event.params.query ?? "")}`,
            severity: "info",
            timeoutMs: 60_000,
            timeoutBehavior: "deny",
          },
        };
      },
      { priority: 50 },
    );
  },
});
```

Hook handlers run sequentially in descending `priority`. Same-priority hooks
keep registration order.

`api.on(name, handler, opts?)` accepts:

- `priority` - handler ordering (higher runs first).
- `timeoutMs` - optional per-hook budget. When set, the hook runner aborts that
  handler after the budget elapses and continues with the next one, instead of
  letting slow setup or recall work consume the caller's configured model
  timeout. Omit it to use the default observation/decision timeout that the
  hook runner applies generically.

Operators can also set hook budgets without patching plugin code:

```json
{
  "plugins": {
    "entries": {
      "my-plugin": {
        "hooks": {
          "timeoutMs": 30000,
          "timeouts": {
            "before_prompt_build": 90000,
            "agent_end": 60000
          }
        }
      }
    }
  }
}
```

`hooks.timeouts.<hookName>` overrides `hooks.timeoutMs`, which overrides the
plugin-authored `api.on(..., { timeoutMs })` value. Each configured value must
be a positive integer no greater than 600000 milliseconds. Prefer per-hook
overrides for known slow hooks so one plugin does not get a longer budget
everywhere.

Each hook receives `event.context.pluginConfig`, the resolved config for the
plugin that registered that handler. Use it for hook decisions that need
current plugin options; OpenClaw injects it per handler without mutating the
shared event object seen by other plugins.

## Hook catalog

Hooks are grouped by the surface they extend. Names in **bold** accept a
decision result (block, cancel, override, or require approval); all others are
observation-only.

**Agent turn**

- `before_model_resolve` - override provider or model before session messages load
- `agent_turn_prepare` - consume queued plugin turn injections and add same-turn context before prompt hooks
- `before_prompt_build` - add dynamic context or system-prompt text before the model call
- `before_agent_start` - compatibility-only combined phase; prefer the two hooks above
- **`before_agent_run`** - inspect the final prompt and session messages before model submission and optionally block the run
- **`before_agent_reply`** - short-circuit the model turn with a synthetic reply or silence
- **`before_agent_finalize`** - inspect the natural final answer and request one more model pass
- `agent_end` - observe final messages, success state, and run duration
- `heartbeat_prompt_contribution` - add heartbeat-only context for background monitor and lifecycle plugins

**Conversation observation**

- `model_call_started` / `model_call_ended` - observe sanitized provider/model call metadata, timing, outcome, and bounded request-id hashes without prompt or response content
- `llm_input` - observe provider input (system prompt, prompt, history)
- `llm_output` - observe provider output, usage, and the resolved `contextTokenBudget` when available

**Tools**

- **`before_tool_call`** - rewrite tool params, block execution, or require approval
- `after_tool_call` - observe tool results, errors, and duration
- `resolve_exec_env` - contribute plugin-owned environment variables to `exec`
- **`tool_result_persist`** - rewrite the assistant message produced from a tool result
- **`before_message_write`** - inspect or block an in-progress message write (rare)

**Messages and delivery**

- **`inbound_claim`** - claim an inbound message before agent routing (synthetic replies)
- `message_received` — observe inbound content, sender, thread, and metadata
- **`message_sending`** — rewrite outbound content or cancel delivery
- **`reply_payload_sending`** — mutate or cancel normalized reply payloads before delivery
- `message_sent` — observe outbound delivery success or failure
- **`before_dispatch`** - inspect or rewrite an outbound dispatch before channel handoff
- **`reply_dispatch`** - participate in the final reply-dispatch pipeline

**Sessions and compaction**

- `session_start` / `session_end` - track session lifecycle boundaries. The event's `reason` is one of `new`, `reset`, `idle`, `daily`, `compaction`, `deleted`, `shutdown`, `restart`, or `unknown`. The `shutdown` and `restart` values fire from the gateway shutdown finalizer when the process is stopped or restarted while sessions are still active, so downstream plugins (such as memory or transcript stores) can finalize ghost rows that would otherwise be left in an open state across restarts. The finalizer is bounded so a slow plugin cannot block SIGTERM/SIGINT.
- `before_compaction` / `after_compaction` - observe or annotate compaction cycles
- `before_reset` - observe session-reset events (`/reset`, programmatic resets)

**Subagents**

- `subagent_spawned` / `subagent_ended` - observe subagent launch and completion.
- `subagent_delivery_target` - compatibility hook for completion delivery when no core session binding can project a route.
- `subagent_spawning` - deprecated compatibility hook. Core now prepares `thread: true` subagent bindings through channel session-binding adapters before `subagent_spawned` fires.
- `subagent_spawned` includes `resolvedModel` and `resolvedProvider` when OpenClaw has resolved the child session's native model before launch.
- `subagent_ended` carries `targetSessionKey` (identity — this matches `subagent_spawned.childSessionKey`), `targetKind` (`"subagent"` or `"acp"`), `reason`, optional `outcome` (`"ok"`, `"error"`, `"timeout"`, `"killed"`, `"reset"`, or `"deleted"`), optional `error`, `runId`, `endedAt`, `accountId`, and `sendFarewell`. It does **not** include `agentId` or `childSessionKey`; use `targetSessionKey` to correlate with the corresponding `subagent_spawned` event.

**Lifecycle**

- `gateway_start` / `gateway_stop` - start or stop plugin-owned services with the Gateway
- `deactivate` - deprecated compatibility alias for `gateway_stop`; use `gateway_stop` in new plugins
- `cron_changed` - observe gateway-owned cron lifecycle changes (added, updated, removed, started, finished, scheduled)
- **`before_install`** - inspect staged skill or plugin install material from a loaded
  plugin runtime

## Debug runtime hooks

Use `before_model_resolve` when a plugin needs to switch the provider or model
for an agent turn. It runs before model resolution; `llm_output` only runs after
a model attempt produces assistant output.

For proof of the effective session model, inspect runtime registrations, then
use `openclaw sessions` or the Gateway session/status surfaces. When debugging
provider payloads, start the Gateway with `--raw-stream` and
`--raw-stream-path <path>`; those flags write raw model stream events to a jsonl
file.

## Tool call policy

`before_tool_call` receives:

- `event.toolName`
- `event.params`
- optional `event.toolKind` and `event.toolInputKind`, host-authoritative
  discriminators for tools that intentionally share names; for example, outer
  code-mode `exec` calls use `toolKind: "code_mode_exec"` and
  include `toolInputKind: "javascript" | "typescript"` when the input language
  is known
- optional `event.derivedPaths`, containing best-effort host-derived target path
  hints for well-known tool envelopes such as `apply_patch`; when present,
  these paths may be incomplete or may over-approximate what the tool will
  actually touch (for example, with malformed or partial inputs)
- optional `event.runId`
- optional `event.toolCallId`
- context fields such as `ctx.agentId`, `ctx.sessionKey`, `ctx.sessionId`,
  `ctx.runId`, `ctx.jobId` (set on cron-driven runs), `ctx.toolKind`,
  `ctx.toolInputKind`, and diagnostic `ctx.trace`

It can return:

```typescript
type BeforeToolCallResult = {
  params?: Record<string, unknown>;
  block?: boolean;
  blockReason?: string;
  requireApproval?: {
    title: string;
    description: string;
    severity?: "info" | "warning" | "critical";
    timeoutMs?: number;
    timeoutBehavior?: "allow" | "deny";
    allowedDecisions?: Array<"allow-once" | "allow-always" | "deny">;
    pluginId?: string;
    onResolution?: (
      decision: "allow-once" | "allow-always" | "deny" | "timeout" | "cancelled",
    ) => Promise<void> | void;
  };
};
```

Hook guard behavior for typed lifecycle hooks:

- `block: true` is terminal and skips lower-priority handlers.
- `block: false` is treated as no decision.
- `params` rewrites the tool parameters for execution.
- `requireApproval` pauses the agent run and asks the user through plugin
  approvals. The `/approve` command can approve both exec and plugin approvals.
  In Codex app-server report-mode native `PreToolUse` relays, this is deferred
  to the matching app-server approval request; see [Codex harness runtime](/plugins/codex-harness-runtime#hook-boundaries).
- A lower-priority `block: true` can still block after a higher-priority hook
  requested approval.
- `onResolution` receives the resolved approval decision - `allow-once`,
  `allow-always`, `deny`, `timeout`, or `cancelled`.

See [Plugin permission requests](/plugins/plugin-permission-requests) for
approval routing, decision behavior, and when to use `requireApproval` instead
of optional tools or exec approvals.

Plugins that need host-level policy can register trusted tool policies with
`api.registerTrustedToolPolicy(...)`. These run before ordinary
`before_tool_call` hooks and before normal hook decisions. Bundled trusted
policies run first; installed-plugin trusted policies run next in plugin-load
order; ordinary `before_tool_call` hooks run after them. Bundled plugins keep
the existing trusted-policy path. Installed plugins must be explicitly enabled
and declare every policy id in `contracts.trustedToolPolicies`; undeclared ids
are rejected before registration. Policy ids are scoped to the registering
plugin, so different plugins may reuse the same local id. Use this tier only
for host-trusted gates such as workspace policy, budget enforcement, or
reserved workflow safety.

### Exec environment hook

`resolve_exec_env` lets plugins contribute environment variables to `exec`
tool invocations after the base exec environment is built and before the
command runs. It receives:

- `event.sessionKey`
- `event.toolName`, currently always `"exec"`
- `event.host`, one of `"gateway"`, `"sandbox"`, or `"node"`
- context fields such as `ctx.agentId`, `ctx.sessionKey`,
  `ctx.messageProvider`, and `ctx.channelId`

Return a `Record<string, string>` to merge into the exec environment. Handlers
run in priority order, and later hook results override earlier hook results for
the same key.

Hook output is filtered through the host exec environment key policy before it
is merged. Invalid keys, `PATH`, and dangerous host override keys such as
`LD_*`, `DYLD_*`, `NODE_OPTIONS`, proxy variables, and TLS override variables
are dropped. The filtered plugin env is included in gateway approval/audit
metadata and forwarded to node-host execution requests.

### Tool result persistence

Tool results can include structured `details` for UI rendering, diagnostics,
media routing, or plugin-owned metadata. Treat `details` as runtime metadata,
not prompt content:

- OpenClaw strips `toolResult.details` before provider replay and compaction
  input so metadata does not become model context.
- Persisted session entries keep only bounded `details`. Oversized details are
  replaced with a compact summary and `persistedDetailsTruncated: true`.
- `tool_result_persist` and `before_message_write` run before the final
  persistence cap. Hooks should still keep returned `details` small and avoid
  placing prompt-relevant text only in `details`; put model-visible tool output
  in `content`.

## Prompt and model hooks

Use the phase-specific hooks for new plugins:

- `before_model_resolve`: receives only the current prompt and attachment
  metadata. Return `providerOverride` or `modelOverride`.
- `agent_turn_prepare`: receives the current prompt, prepared session messages,
  and any exactly-once queued injections drained for this session. Return
  `prependContext` or `appendContext`.
- `before_prompt_build`: receives the current prompt and session messages.
  Return `prependContext`, `appendContext`, `systemPrompt`,
  `prependSystemContext`, or `appendSystemContext`.
- `heartbeat_prompt_contribution`: runs only for heartbeat turns and returns
  `prependContext` or `appendContext`. It is intended for background monitors
  that need to summarize current state without changing user-initiated turns.

`before_agent_start` remains for compatibility. Prefer the explicit hooks above
so your plugin does not depend on a legacy combined phase.

`before_agent_run` runs after prompt construction and before any model input,
including prompt-local image loading and `llm_input` observation. It receives
the current user input as `prompt`, plus loaded session history in `messages`
and the active system prompt. Return `{ outcome: "block", reason, message? }`
to stop the run before the model can read the prompt. `reason` is internal;
`message` is the user-facing replacement. The only supported outcomes are
`pass` and `block`; unsupported decision shapes fail closed.

When a run is blocked, OpenClaw stores only the replacement text in
`message.content` plus non-sensitive block metadata such as the blocking plugin
id and timestamp. The original user text is not retained in transcript or future
context. Internal block reasons are treated as sensitive and excluded from
transcript, history, broadcast, log, and diagnostics payloads. Observability
should use sanitized fields such as blocker id, outcome, timestamp, or a safe
category.

`before_agent_start` and `agent_end` include `event.runId` when OpenClaw can
identify the active run. The same value is also available on `ctx.runId`.
Cron-driven runs also expose `ctx.jobId` (the originating cron job id) so
plugin hooks can scope metrics, side effects, or state to a specific scheduled
job.

For channel-originated runs, `ctx.channel` and `ctx.messageProvider` identify
the provider surface such as `discord` or `telegram`, while `ctx.channelId` is
the conversation target identifier when OpenClaw can derive one from the session
key or delivery metadata.

When sender identity is available, agent hook contexts also include:

- `ctx.senderId` — channel-scoped sender ID (e.g. Feishu `open_id`, Discord
  user ID). Populated when the run originates from a user message with known
  sender metadata.
- `ctx.chatId` — transport-native conversation identifier (e.g. Feishu
  `chat_id`, Telegram `chat_id`). Populated when the originating channel
  provides a native conversation ID.
- `ctx.channelContext.sender.id` — the same sender ID as `ctx.senderId`, under a
  channel-owned object that plugins can extend with channel-specific fields.
- `ctx.channelContext.chat.id` — the same conversation ID as `ctx.chatId`, under a
  channel-owned object that plugins can extend with channel-specific fields.

Core only defines the nested `id` fields. Channel plugins that pass richer
sender or chat metadata through the inbound helper can augment
`PluginHookChannelSenderContext` or `PluginHookChannelChatContext` from
`openclaw/plugin-sdk/channel-inbound`:

```ts
declare module "openclaw/plugin-sdk/channel-inbound" {
  interface PluginHookChannelSenderContext {
    unionId?: string;
    userId?: string;
  }
}
```

Channel plugins pass those fields through the inbound SDK helper:

```ts
buildChannelInboundEventContext({
  // ...
  channelContext: {
    sender: { id: senderOpenId, unionId, userId },
    chat: { id: chatId },
  },
});
```

These fields are optional and absent for system-originated runs (heartbeat,
cron, exec-event).

`ctx.senderExternalId` remains as a deprecated source-compatibility field for
older plugins. Core does not populate it; new channel-specific sender identities
should live under `ctx.channelContext.sender` through module augmentation.

`agent_end` is an observation hook. Gateway and persistent harness paths run it
fire-and-forget after the turn, while short-lived one-shot CLI paths wait for the
hook promise before process cleanup so trusted plugins can flush terminal
observability or capture state. The hook runner applies a 30 second timeout so a
wedged plugin or embedding endpoint cannot leave the hook promise pending
forever. A timeout is logged and OpenClaw continues; it does not cancel
plugin-owned network work unless the plugin also uses its own abort signal.

Use `model_call_started` and `model_call_ended` for provider-call telemetry
that should not receive raw prompts, history, responses, headers, request
bodies, or provider request IDs. These hooks include stable metadata such as
`runId`, `callId`, `provider`, `model`, optional `api`/`transport`, terminal
`durationMs`/`outcome`, and `upstreamRequestIdHash` when OpenClaw can derive a
bounded provider request-id hash. When the runtime has resolved context-window
metadata, the hook event and context also include `contextTokenBudget`, the
effective token budget after model/config/agent caps, plus
`contextWindowSource` and `contextWindowReferenceTokens` when a lower cap was
applied.

`before_agent_finalize` runs only when a harness is about to accept a natural
final assistant answer. It is not the `/stop` cancellation path and does not
run when the user aborts a turn. Return `{ action: "revise", reason }` to ask
the harness for one more model pass before finalization, `{ action:
"finalize", reason? }` to force finalization, or omit a result to continue.
Codex native `Stop` hooks are relayed into this hook as OpenClaw
`before_agent_finalize` decisions.

When returning `action: "revise"`, plugins can include `retry` metadata to make
the extra model pass bounded and replay-safe:

```typescript
type BeforeAgentFinalizeRetry = {
  instruction: string;
  idempotencyKey?: string;
  maxAttempts?: number;
};
```

`instruction` is appended to the revision reason sent to the harness.
`idempotencyKey` lets the host count retries for the same plugin request across
equivalent finalize decisions, and `maxAttempts` caps how many extra passes the
host will allow before continuing with the natural final answer.

Non-bundled plugins that need raw conversation hooks (`before_model_resolve`,
`before_agent_reply`, `llm_input`, `llm_output`, `before_agent_finalize`,
`agent_end`, or `before_agent_run`) must set:

```json
{
  "plugins": {
    "entries": {
      "my-plugin": {
        "hooks": {
          "allowConversationAccess": true
        }
      }
    }
  }
}
```

Prompt-mutating hooks and durable next-turn injections can be disabled per plugin
with `plugins.entries.<id>.hooks.allowPromptInjection=false`.

### Session extensions and next-turn injections

Workflow plugins can persist small JSON-compatible session state with
`api.registerSessionExtension(...)` and update it through the Gateway
`sessions.pluginPatch` method. Session rows project registered extension state
through `pluginExtensions`, letting Control UI and other clients render
plugin-owned status without learning plugin internals.

Use `api.enqueueNextTurnInjection(...)` when a plugin needs durable context to
reach the next model turn exactly once. OpenClaw drains queued injections before
prompt hooks, drops expired injections, and deduplicates by `idempotencyKey`
per plugin. This is the right seam for approval resumes, policy summaries,
background monitor deltas, and command continuations that should be visible to
the model on the next turn but should not become permanent system prompt text.

Cleanup semantics are part of the contract. Session extension cleanup and
runtime lifecycle cleanup callbacks receive `reset`, `delete`, `disable`, or
`restart`. The host removes the owning plugin's persistent session extension
state and pending next-turn injections for reset/delete/disable; restart keeps
durable session state while cleanup callbacks let plugins release scheduler
jobs, run context, and other out-of-band resources for the old runtime
generation.

## Message hooks

Use message hooks for channel-level routing and delivery policy:

- `message_received`: observe inbound content, sender, `threadId`, `messageId`,
  `senderId`, optional run/session correlation, and metadata.
- `message_sending`: rewrite `content` or return `{ cancel: true }`.
- `reply_payload_sending`: rewrite normalized `ReplyPayload` objects (including
  `presentation`, `delivery`, media refs, and text) or return `{ cancel: true }`.
- `message_sent`: observe final success or failure.

For audio-only TTS replies, `content` may contain the hidden spoken transcript
even when the channel payload has no visible text/caption. Rewriting that
`content` updates the hook-visible transcript only; it is not rendered as a
media caption.

`reply_payload_sending` events may include `usageState`, a best-effort live
per-turn model/usage/context snapshot. Durable delivery, recovered replay, and
replies without exact run correlation omit it.

Message hook contexts expose stable correlation fields when available:
`ctx.sessionKey`, `ctx.runId`, `ctx.messageId`, `ctx.senderId`, `ctx.trace`,
`ctx.traceId`, `ctx.spanId`, `ctx.parentSpanId`, and `ctx.callDepth`. Inbound
and `before_dispatch` contexts also expose reply metadata when the channel has
visibility-filtered quoted message data: `replyToId`, `replyToIdFull`,
`replyToBody`, `replyToSender`, and `replyToIsQuote`. Prefer these first-class
fields before reading legacy metadata.

Prefer typed `threadId` and `replyToId` fields before using channel-specific
metadata.

Decision rules:

- `message_sending` with `cancel: true` is terminal.
- `message_sending` with `cancel: false` is treated as no decision.
- Rewritten `content` continues to lower-priority hooks unless a later hook
  cancels delivery.
- `reply_payload_sending` runs after payload normalization and before channel
  delivery, including replies routed back to the originating channel. Handlers
  run sequentially and each handler sees the latest payload produced by
  higher-priority handlers.
- `reply_payload_sending` payloads do not expose runtime trust markers such as
  `trustedLocalMedia`; plugins can edit payload shape but cannot grant local
  media trust.
- `message_sending` can return `cancelReason` and bounded `metadata` with a
  cancellation. New message lifecycle APIs expose this as a suppressed delivery
  outcome with reason `cancelled_by_message_sending_hook`; legacy direct
  delivery keeps returning an empty result array for compatibility.
- `message_sent` is observation-only. Handler failures are logged and do not
  change the delivery result.

## Install hooks

Use `security.installPolicy` for operator-owned allow/block decisions. That
policy runs from OpenClaw config, covers CLI install and update paths, and fails
closed when enabled but unavailable.

`before_install` is a plugin-runtime lifecycle hook. It runs after
`security.installPolicy` only in the OpenClaw process where plugin hooks have
already been loaded, such as Gateway-backed install flows. It is useful for
plugin-owned observations, warnings, and compatibility checks, but it is not the
primary enterprise or host security boundary for installs. The `builtinScan`
field remains in the event payload for compatibility, but OpenClaw no longer
runs built-in install-time dangerous-code blocking, so it is an empty `ok`
result. Return additional findings or `{ block: true, blockReason }` to stop the
install in that process.

`block: true` is terminal. `block: false` is treated as no decision.
Handler failures block the install fail-closed.

## Gateway lifecycle

Use `gateway_start` for plugin services that need Gateway-owned state. The
context exposes `ctx.config`, `ctx.workspaceDir`, and `ctx.getCron?.()` for
cron inspection and updates. Use `gateway_stop` to clean up long-running
resources.

Do not rely on the internal `gateway:startup` hook for plugin-owned runtime
services.

`cron_changed` fires for gateway-owned cron lifecycle events with a typed
event payload covering `added`, `updated`, `removed`, `started`, `finished`,
and `scheduled` reasons. The event carries a `PluginHookGatewayCronJob`
snapshot (including `state.nextRunAtMs`, `state.lastRunStatus`, and
`state.lastError` when present) plus a `PluginHookGatewayCronDeliveryStatus`
of `not-requested` | `delivered` | `not-delivered` | `unknown`. Removed
events still carry the deleted job snapshot so external schedulers can
reconcile state. Use `ctx.getCron?.()` and `ctx.config` from the runtime
context when syncing external wake schedulers, and keep OpenClaw as the
source of truth for due checks and execution.

## Upcoming deprecations

A few hook-adjacent surfaces are deprecated but still supported. Migrate
before the next major release:

- **Plaintext channel envelopes** in `inbound_claim` and `message_received`
  handlers. Read `BodyForAgent` and the structured user-context blocks
  instead of parsing flat envelope text. See
  [Plaintext channel envelopes → BodyForAgent](/plugins/sdk-migration#active-deprecations).
- **`before_agent_start`** remains for compatibility. New plugins should use
  `before_model_resolve` and `before_prompt_build` instead of the combined
  phase.
- **`subagent_spawning`** remains for compatibility with older plugins, but
  new plugins should not return thread routing from it. Core prepares
  `thread: true` subagent bindings through channel session-binding adapters
  before `subagent_spawned` fires.
- **`deactivate`** remains as a deprecated cleanup compatibility alias until
  after 2026-08-16. New plugins should use `gateway_stop`.
- **`onResolution` in `before_tool_call`** now uses the typed
  `PluginApprovalResolution` union (`allow-once` / `allow-always` / `deny` /
  `timeout` / `cancelled`) instead of a free-form `string`.

For the full list - memory capability registration, provider thinking
profile, external auth providers, provider discovery types, task runtime
accessors, and the `command-auth` → `command-status` rename - see
