# Hooks

Hooks provide an extensible event-driven system for automating actions in response to agent commands and events. Hooks are automatically discovered from directories and can be inspected with `openclaw hooks`, while hook-pack installation and updates now go through `openclaw plugins`.

## Getting Oriented

Hooks are small scripts that run when something happens. There are two kinds:

- **Hooks** (this page): run inside the Gateway when agent events fire, like `/new`, `/reset`, `/stop`, or lifecycle events.
- **Webhooks**: external HTTP webhooks that let other systems trigger work in OpenClaw. See [Webhook Hooks](/automation/webhook) or use `openclaw webhooks` for Gmail helper commands.

Hooks can also be bundled inside plugins; see [Plugin hooks](/plugins/architecture#provider-runtime-hooks). `openclaw hooks list` shows both standalone hooks and plugin-managed hooks.

Common uses:

- Save a memory snapshot when you reset a session
- Keep an audit trail of commands for troubleshooting or compliance
- Trigger follow-up automation when a session starts or ends
- Write files into the agent workspace or call external APIs when events fire

If you can write a small TypeScript function, you can write a hook. Managed and bundled hooks are trusted local code. Workspace hooks are discovered automatically, but OpenClaw keeps them disabled until you explicitly enable them via the CLI or config.

## Overview

The hooks system allows you to:

- Save session context to memory when `/new` is issued
- Log all commands for auditing
- Trigger custom automations on agent lifecycle events
- Extend OpenClaw's behavior without modifying core code

## Getting Started

### Bundled Hooks

OpenClaw ships with four bundled hooks that are automatically discovered:

- **💾 session-memory**: Saves session context to your agent workspace (default `~/.openclaw/workspace/memory/`) when you issue `/new` or `/reset`
- **📎 bootstrap-extra-files**: Injects additional workspace bootstrap files from configured glob/path patterns during `agent:bootstrap`
- **📝 command-logger**: Logs all command events to `~/.openclaw/logs/commands.log`
- **🚀 boot-md**: Runs `BOOT.md` when the gateway starts (requires internal hooks enabled)

List available hooks:

```bash
openclaw hooks list
```

Enable a hook:

```bash
openclaw hooks enable session-memory
```

Check hook status:

```bash
openclaw hooks check
```

Get detailed information:

```bash
openclaw hooks info session-memory
```

### Onboarding

During onboarding (`openclaw onboard`), you'll be prompted to enable recommended hooks. The wizard automatically discovers eligible hooks and presents them for selection.

### Trust Boundary

Hooks run inside the Gateway process. Treat bundled hooks, managed hooks, and `hooks.internal.load.extraDirs` as trusted local code. Workspace hooks under `<workspace>/hooks/` are repo-local code, so OpenClaw requires an explicit enable step before loading them.

## Hook Discovery

Hooks are automatically discovered from these directories, in order of increasing override precedence:

1. **Bundled hooks**: shipped with OpenClaw; located at `<openclaw>/dist/hooks/bundled/` for npm installs (or a sibling `hooks/bundled/` for compiled binaries)
2. **Plugin hooks**: hooks bundled inside installed plugins (see [Plugin hooks](/plugins/architecture#provider-runtime-hooks))
3. **Managed hooks**: `~/.openclaw/hooks/` (user-installed, shared across workspaces; can override bundled and plugin hooks). **Extra hook directories** configured via `hooks.internal.load.extraDirs` are also treated as managed hooks and share the same override precedence.
4. **Workspace hooks**: `<workspace>/hooks/` (per-agent, disabled by default until explicitly enabled; cannot override hooks from other sources)

Workspace hooks can add new hook names for a repo, but they cannot override bundled, managed, or plugin-provided hooks with the same name.

Managed hook directories can be either a **single hook** or a **hook pack** (package directory).

Each hook is a directory containing:

```
my-hook/
├── HOOK.md          # Metadata + documentation
└── handler.ts       # Handler implementation
```

## Hook Packs (npm/archives)

Hook packs are standard npm packages that export one or more hooks via `openclaw.hooks` in
`package.json`. Install them with:

```bash
openclaw plugins install <path-or-spec>
```

Npm specs are registry-only (package name + optional exact version or dist-tag).
Git/URL/file specs and semver ranges are rejected.

Bare specs and `@latest` stay on the stable track. If npm resolves either of
those to a prerelease, OpenClaw stops and asks you to opt in explicitly with a
prerelease tag such as `@beta`/`@rc` or an exact prerelease version.

Example `package.json`:

```json
{
  "name": "@acme/my-hooks",
  "version": "0.1.0",
  "openclaw": {
    "hooks": ["./hooks/my-hook", "./hooks/other-hook"]
  }
}
```

Each entry points to a hook directory containing `HOOK.md` and `handler.ts` (or `index.ts`).
Hook packs can ship dependencies; they will be installed under `~/.openclaw/hooks/<id>`.
Each `openclaw.hooks` entry must stay inside the package directory after symlink
resolution; entries that escape are rejected.

Security note: `openclaw plugins install` installs hook-pack dependencies with `npm install --ignore-scripts`
(no lifecycle scripts). Keep hook pack dependency trees "pure JS/TS" and avoid packages that rely
on `postinstall` builds.

## Hook Structure

### HOOK.md Format

The `HOOK.md` file contains metadata in YAML frontmatter plus Markdown documentation:

```markdown
---
name: my-hook
description: "Short description of what this hook does"
homepage: https://docs.openclaw.ai/automation/hooks#my-hook
metadata:
  { "openclaw": { "emoji": "🔗", "events": ["command:new"], "requires": { "bins": ["node"] } } }
---

# My Hook

Detailed documentation goes here...

## What It Does

- Listens for `/new` commands
- Performs some action
- Logs the result

## Requirements

- Node.js must be installed

## Configuration

No configuration needed.
```

### Metadata Fields

The `metadata.openclaw` object supports:

- **`emoji`**: Display emoji for CLI (e.g., `"💾"`)
- **`events`**: Array of events to listen for (e.g., `["command:new", "command:reset"]`)
- **`export`**: Named export to use (defaults to `"default"`)
- **`homepage`**: Documentation URL
- **`os`**: Required platforms (e.g., `["darwin", "linux"]`)
- **`requires`**: Optional requirements
  - **`bins`**: Required binaries on PATH (e.g., `["git", "node"]`)
  - **`anyBins`**: At least one of these binaries must be present
  - **`env`**: Required environment variables
  - **`config`**: Required config paths (e.g., `["workspace.dir"]`)
- **`always`**: Bypass eligibility checks (boolean)
- **`install`**: Installation methods (for bundled hooks: `[{"id":"bundled","kind":"bundled"}]`)

### Handler Implementation

The `handler.ts` file exports a `HookHandler` function:

```typescript
const myHandler = async (event) => {
  // Only trigger on 'new' command
  if (event.type !== "command" || event.action !== "new") {
    return;
  }

  console.log(`[my-hook] New command triggered`);
  console.log(`  Session: ${event.sessionKey}`);
  console.log(`  Timestamp: ${event.timestamp.toISOString()}`);

  // Your custom logic here

  // Optionally send message to user
  event.messages.push("✨ My hook executed!");
};

export default myHandler;
```

#### Event Context

Each event includes:

```typescript
{
  type: 'command' | 'session' | 'agent' | 'gateway' | 'message',
  action: string,              // e.g., 'new', 'reset', 'stop', 'received', 'sent'
  sessionKey: string,          // Session identifier
  timestamp: Date,             // When the event occurred
  messages: string[],          // Push messages here to send to user
  context: {
    // Command events (command:new, command:reset):
    sessionEntry?: SessionEntry,       // current session entry
    previousSessionEntry?: SessionEntry, // pre-reset entry (preferred for session-memory)
    commandSource?: string,            // e.g., 'whatsapp', 'telegram'
    senderId?: string,
    workspaceDir?: string,
    cfg?: OpenClawConfig,
    // Command events (command:stop only):
    sessionId?: string,
    // Agent bootstrap events (agent:bootstrap):
    bootstrapFiles?: WorkspaceBootstrapFile[],
    // Message events (see Message Events section for full details):
    from?: string,             // message:received
    to?: string,               // message:sent
    content?: string,
    channelId?: string,
    success?: boolean,         // message:sent
  }
}
```

## Event Types

### Command Events

Triggered when agent commands are issued:

- **`command`**: All command events (general listener)
- **`command:new`**: When `/new` command is issued
- **`command:reset`**: When `/reset` command is issued
- **`command:stop`**: When `/stop` command is issued

### Session Events

- **`session:compact:before`**: Right before compaction summarizes history
- **`session:compact:after`**: After compaction completes with summary metadata

Internal hook payloads emit these as `type: "session"` with `action: "compact:before"` / `action: "compact:after"`; listeners subscribe with the combined keys above.
Specific handler registration uses the literal key format `${type}:${action}`. For these events, register `session:compact:before` and `session:compact:after`.

### Agent Events

- **`agent:bootstrap`**: Before workspace bootstrap files are injected (hooks may mutate `context.bootstrapFiles`)

### Gateway Events

Triggered when the gateway starts:

- **`gateway:startup`**: After channels start and hooks are loaded

### Message Events

Triggered when messages are received or sent:

- **`message`**: All message events (general listener)
- **`message:received`**: When an inbound message is received from any channel. Fires early in processing before media understanding. Content may contain raw placeholders like `<media:audio>` for media attachments that haven't been processed yet.
- **`message:transcribed`**: When a message has been fully processed, including audio transcription and link understanding. At this point, `transcript` contains the full transcript text for audio messages. Use this hook when you need access to transcribed audio content.
- **`message:preprocessed`**: Fires for every message after all media + link understanding completes, giving hooks access to the fully enriched body (transcripts, image descriptions, link summaries) before the agent sees it.
- **`message:sent`**: When an outbound message is successfully sent

#### Message Event Context

Message events include rich context about the message:

```typescript
// message:received context
{
  from: string,           // Sender identifier (phone number, user ID, etc.)
  content: string,        // Message content
  timestamp?: number,     // Unix timestamp when received
  channelId: string,      // Channel (e.g., "whatsapp", "telegram", "discord")
  accountId?: string,     // Provider account ID for multi-account setups
  conversationId?: string, // Chat/conversation ID
  messageId?: string,     // Message ID from the provider
  metadata?: {            // Additional provider-specific data
    to?: string,
    provider?: string,
    surface?: string,
    threadId?: string | number,
    senderId?: string,
    senderName?: string,
    senderUsername?: string,
    senderE164?: string,
    guildId?: string,     // Discord guild / server ID
    channelName?: string, // Channel name (e.g., Discord channel name)
  }
}

// message:sent context
{
  to: string,             // Recipient identifier
  content: string,        // Message content that was sent
  success: boolean,       // Whether the send succeeded
  error?: string,         // Error message if sending failed
  channelId: string,      // Channel (e.g., "whatsapp", "telegram", "discord")
  accountId?: string,     // Provider account ID
  conversationId?: string, // Chat/conversation ID
  messageId?: string,     // Message ID returned by the provider
  isGroup?: boolean,      // Whether this outbound message belongs to a group/channel context
  groupId?: string,       // Group/channel identifier for correlation with message:received
}

// message:transcribed context
{
  from?: string,          // Sender identifier
  to?: string,            // Recipient identifier
  body?: string,          // Raw inbound body before enrichment
  bodyForAgent?: string,  // Enriched body visible to the agent
  transcript: string,     // Audio transcript text
  timestamp?: number,     // Unix timestamp when received
  channelId: string,      // Channel (e.g., "telegram", "whatsapp")
  conversationId?: string,
  messageId?: string,
  senderId?: string,      // Sender user ID
  senderName?: string,    // Sender display name
  senderUsername?: string,
  provider?: string,      // Provider name
  surface?: string,       // Surface name
  mediaPath?: string,     // Path to the media file that was transcribed
  mediaType?: string,     // MIME type of the media
}

// message:preprocessed context
{
  from?: string,          // Sender identifier
  to?: string,            // Recipient identifier
  body?: string,          // Raw inbound body
  bodyForAgent?: string,  // Final enriched body after media/link understanding
  transcript?: string,    // Transcript when audio was present
  timestamp?: number,     // Unix timestamp when received
  channelId: string,      // Channel (e.g., "telegram", "whatsapp")
  conversationId?: string,
  messageId?: string,
  senderId?: string,      // Sender user ID
  senderName?: string,    // Sender display name
  senderUsername?: string,
  provider?: string,      // Provider name
  surface?: string,       // Surface name
  mediaPath?: string,     // Path to the media file
  mediaType?: string,     // MIME type of the media
  isGroup?: boolean,
  groupId?: string,
}
```

#### Example: Message Logger Hook

```typescript
const isMessageReceivedEvent = (event: { type: string; action: string }) =>
  event.type === "message" && event.action === "received";
const isMessageSentEvent = (event: { type: string; action: string }) =>
  event.type === "message" && event.action === "sent";

const handler = async (event) => {
  if (isMessageReceivedEvent(event as { type: string; action: string })) {
    console.log(`[message-logger] Received from ${event.context.from}: ${event.context.content}`);
  } else if (isMessageSentEvent(event as { type: string; action: string })) {
    console.log(`[message-logger] Sent to ${event.context.to}: ${event.context.content}`);
  }
};

export default handler;
```

### Tool Result Hooks (Plugin API)

These hooks are not event-stream listeners; they let plugins synchronously adjust tool results before OpenClaw persists them.

- **`tool_result_persist`**: transform tool results before they are written to the session transcript. Must be synchronous; return the updated tool result payload or `undefined` to keep it as-is. See [Agent Loop](/concepts/agent-loop).

### Plugin Hook Events

Compaction lifecycle hooks exposed through the plugin hook runner:

- **`before_compaction`**: Runs before compaction with count/token metadata
- **`after_compaction`**: Runs after compaction with compaction summary metadata

### Future Events

Planned event types:

- **`session:start`**: When a new session begins
- **`session:end`**: When a session ends
- **`agent:error`**: When an agent encounters an error

## Creating Custom Hooks

### 1. Choose Location

- **Workspace hooks** (`<workspace>/hooks/`): Per-agent; can add new hook names but cannot override bundled, managed, or plugin hooks with the same name
- **Managed hooks** (`~/.openclaw/hooks/`): Shared across workspaces; can override bundled and plugin hooks

### 2. Create Directory Structure

```bash
mkdir -p ~/.openclaw/hooks/my-hook
cd ~/.openclaw/hooks/my-hook
```

### 3. Create HOOK.md

```markdown
---
name: my-hook
description: "Does something useful"
metadata: { "openclaw": { "emoji": "🎯", "events": ["command:new"] } }
---

# My Custom Hook

This hook does something useful when you issue `/new`.
```

### 4. Create handler.ts

```typescript
const handler = async (event) => {
  if (event.type !== "command" || event.action !== "new") {
    return;
  }

  console.log("[my-hook] Running!");
  // Your logic here
};

export default handler;
```

### 5. Enable and Test

```bash
# Verify hook is discovered
openclaw hooks list

# Enable it
openclaw hooks enable my-hook

# Restart your gateway process (menu bar app restart on macOS, or restart your dev process)

# Trigger the event
# Send /new via your messaging channel
```

## Configuration

### New Config Format (Recommended)

```json
{
  "hooks": {
    "internal": {
      "enabled": true,
      "entries": {
        "session-memory": { "enabled": true },
        "command-logger": { "enabled": false }
      }
    }
  }
}
```

### Per-Hook Configuration

Hooks can have custom configuration:

```json
{
  "hooks": {
    "internal": {
      "enabled": true,
      "entries": {
        "my-hook": {
          "enabled": true,
          "env": {
            "MY_CUSTOM_VAR": "value"
          }
        }
      }
    }
  }
}
```

### Extra Directories

Load hooks from additional directories (treated as managed hooks, same override precedence):

```json
{
  "hooks": {
    "internal": {
      "enabled": true,
      "load": {
        "extraDirs": ["/path/to/more/hooks"]
      }
    }
  }
}
```

### Legacy Config Format (Still Supported)

The old config format still works for backwards compatibility:

```json
{
  "hooks": {
    "internal": {
      "enabled": true,
      "handlers": [
        {
          "event": "command:new",
          "module": "./hooks/handlers/my-handler.ts",
          "export": "default"
        }
      ]
    }
  }
}
```

Note: `module` must be a workspace-relative path. Absolute paths and traversal outside the workspace are rejected.

**Migration**: Use the new discovery-based system for new hooks. Legacy handlers are loaded after directory-based hooks.

## CLI Commands

### List Hooks

```bash
# List all hooks
openclaw hooks list

# Show only eligible hooks
openclaw hooks list --eligible

# Verbose output (show missing requirements)
openclaw hooks list --verbose

# JSON output
openclaw hooks list --json
```

### Hook Information

```bash
# Show detailed info about a hook
openclaw hooks info session-memory

# JSON output
openclaw hooks info session-memory --json
```

### Check Eligibility

```bash
# Show eligibility summary
openclaw hooks check

# JSON output
openclaw hooks check --json
```

### Enable/Disable

```bash
# Enable a hook
openclaw hooks enable session-memory

# Disable a hook
openclaw hooks disable command-logger
```

## Bundled hook reference

### session-memory

Saves session context to memory when you issue `/new` or `/reset`.

**Events**: `command:new`, `command:reset`

**Requirements**: `workspace.dir` must be configured

**Output**: `<workspace>/memory/YYYY-MM-DD-slug.md` (defaults to `~/.openclaw/workspace`)

**What it does**:

1. Uses the pre-reset session entry to locate the correct transcript
2. Extracts the last 15 user/assistant messages from the conversation (configurable)
3. Uses LLM to generate a descriptive filename slug
4. Saves session metadata to a dated memory file

**Example output**:

```markdown
# Session: 2026-01-16 14:30:00 UTC

- **Session Key**: agent:main:main
- **Session ID**: abc123def456
- **Source**: telegram

## Conversation Summary

user: Can you help me design the API?
assistant: Sure! Let's start with the endpoints...
```

**Filename examples**:

- `2026-01-16-vendor-pitch.md`
- `2026-01-16-api-design.md`
- `2026-01-16-1430.md` (fallback timestamp if slug generation fails)

**Enable**:

```bash
openclaw hooks enable session-memory
```

### bootstrap-extra-files

Injects additional bootstrap files (for example monorepo-local `AGENTS.md` / `TOOLS.md`) during `agent:bootstrap`.

**Events**: `agent:bootstrap`

**Requirements**: `workspace.dir` must be configured

**Output**: No files written; bootstrap context is modified in-memory only.

**Config**:

```json
{
  "hooks": {
    "internal": {
      "enabled": true,
      "entries": {
        "bootstrap-extra-files": {
          "enabled": true,
          "paths": ["packages/*/AGENTS.md", "packages/*/TOOLS.md"]
        }
      }
    }
  }
}
```

**Config options**:

- `paths` (string[]): glob/path patterns to resolve from the workspace.
- `patterns` (string[]): alias of `paths`.
- `files` (string[]): alias of `paths`.

**Notes**:

- Paths are resolved relative to workspace.
- Files must stay inside workspace (realpath-checked).
- Only recognized bootstrap basenames are loaded (`AGENTS.md`, `SOUL.md`, `TOOLS.md`, `IDENTITY.md`, `USER.md`, `HEARTBEAT.md`, `BOOTSTRAP.md`, `MEMORY.md`, `memory.md`).
- For subagent/cron sessions a narrower allowlist applies (`AGENTS.md`, `TOOLS.md`, `SOUL.md`, `IDENTITY.md`, `USER.md`).

**Enable**:

```bash
openclaw hooks enable bootstrap-extra-files
```

### command-logger

Logs all command events to a centralized audit file.

**Events**: `command`

**Requirements**: None

**Output**: `~/.openclaw/logs/commands.log`

**What it does**:

1. Captures event details (command action, timestamp, session key, sender ID, source)
2. Appends to log file in JSONL format
3. Runs silently in the background

**Example log entries**:

```jsonl
{"timestamp":"2026-01-16T14:30:00.000Z","action":"new","sessionKey":"agent:main:main","senderId":"+1234567890","source":"telegram"}
{"timestamp":"2026-01-16T15:45:22.000Z","action":"stop","sessionKey":"agent:main:main","senderId":"user@example.com","source":"whatsapp"}
```

**View logs**:

```bash
# View recent commands
tail -n 20 ~/.openclaw/logs/commands.log

# Pretty-print with jq
cat ~/.openclaw/logs/commands.log | jq .

# Filter by action
grep '"action":"new"' ~/.openclaw/logs/commands.log | jq .
```

**Enable**:

```bash
openclaw hooks enable command-logger
```

### boot-md

Runs `BOOT.md` when the gateway starts (after channels start).
Internal hooks must be enabled for this to run.

**Events**: `gateway:startup`

**Requirements**: `workspace.dir` must be configured

**What it does**:

1. Reads `BOOT.md` from your workspace
2. Runs the instructions via the agent runner
3. Sends any requested outbound messages via the message tool

**Enable**:

```bash
openclaw hooks enable boot-md
```

## Best Practices

### Keep Handlers Fast

Hooks run during command processing. Keep them lightweight:

```typescript
// ✓ Good - async work, returns immediately
const handler: HookHandler = async (event) => {
  void processInBackground(event); // Fire and forget
};

// ✗ Bad - blocks command processing
const handler: HookHandler = async (event) => {
  await slowDatabaseQuery(event);
  await evenSlowerAPICall(event);
};
```

### Handle Errors Gracefully

Always wrap risky operations:

```typescript
const handler: HookHandler = async (event) => {
  try {
    await riskyOperation(event);
  } catch (err) {
    console.error("[my-handler] Failed:", err instanceof Error ? err.message : String(err));
    // Don't throw - let other handlers run
  }
};
```

### Filter Events Early

Return early if the event isn't relevant:

```typescript
const handler: HookHandler = async (event) => {
  // Only handle 'new' commands
  if (event.type !== "command" || event.action !== "new") {
    return;
  }

  // Your logic here
};
```

### Use Specific Event Keys

Specify exact events in metadata when possible:

```yaml
metadata: { "openclaw": { "events": ["command:new"] } } # Specific
```

Rather than:

```yaml
metadata: { "openclaw": { "events": ["command"] } } # General - more overhead
```

## Debugging

### Enable Hook Logging

The gateway logs hook loading at startup:

```
Registered hook: session-memory -> command:new
Registered hook: bootstrap-extra-files -> agent:bootstrap
Registered hook: command-logger -> command
Registered hook: boot-md -> gateway:startup
```

### Check Discovery

List all discovered hooks:

```bash
openclaw hooks list --verbose
```

### Check Registration

In your handler, log when it's called:

```typescript
const handler: HookHandler = async (event) => {
  console.log("[my-handler] Triggered:", event.type, event.action);
  // Your logic
};
```

### Verify Eligibility

Check why a hook isn't eligible:

```bash
openclaw hooks info my-hook
```

Look for missing requirements in the output.

## Testing

### Gateway Logs

Monitor gateway logs to see hook execution:

```bash
# macOS
./scripts/clawlog.sh -f

# Other platforms
tail -f ~/.openclaw/gateway.log
```

### Test Hooks Directly

Test your handlers in isolation:

```typescript
import { test } from "vitest";
import myHandler from "./hooks/my-hook/handler.js";

test("my handler works", async () => {
  const event = {
    type: "command",
    action: "new",
    sessionKey: "test-session",
    timestamp: new Date(),
    messages: [],
    context: { foo: "bar" },
  };

  await myHandler(event);

  // Assert side effects
});
```

## Troubleshooting

### Hook Not Discovered

1. Check directory structure:

   ```bash
   ls -la ~/.openclaw/hooks/my-hook/
   # Should show: HOOK.md, handler.ts
   ```

2. Verify HOOK.md format:

   ```bash
   cat ~/.openclaw/hooks/my-hook/HOOK.md
   # Should have YAML frontmatter with name and metadata
   ```

3. List all discovered hooks:

   ```bash
   openclaw hooks list
   ```

### Hook Not Eligible

Check requirements:

```bash
openclaw hooks info my-hook
```

Look for missing:

- Binaries (check PATH)
- Environment variables
- Config values
- OS compatibility

### Hook Not Executing

1. Verify hook is enabled:

   ```bash
   openclaw hooks list
   # Should show ✓ next to enabled hooks
   ```

2. Restart your gateway process so hooks reload.

3. Check gateway logs for errors:

   ```bash
   ./scripts/clawlog.sh | grep hook
   ```

### Handler Errors

Check for TypeScript/import errors:

```bash
# Test import directly
node -e "import('./path/to/handler.ts').then(console.log)"
```

## Migration Guide

### From Legacy Config to Discovery

**Before**:

```json
{
  "hooks": {
    "internal": {
      "enabled": true,
      "handlers": [
        {
          "event": "command:new",
          "module": "./hooks/handlers/my-handler.ts"
        }
      ]
    }
  }
}
```

**After**:

1. Create hook directory:

   ```bash
   mkdir -p ~/.openclaw/hooks/my-hook
   mv ./hooks/handlers/my-handler.ts ~/.openclaw/hooks/my-hook/handler.ts
   ```

2. Create HOOK.md:

   ```markdown
   ---
   name: my-hook
   description: "My custom hook"
   metadata: { "openclaw": { "emoji": "🎯", "events": ["command:new"] } }
   ---

   # My Hook

   Does something useful.
   ```

3. Update config:

   ```json
   {
     "hooks": {
       "internal": {
         "enabled": true,
         "entries": {
           "my-hook": { "enabled": true }
         }
       }
     }
   }
   ```

4. Verify and restart your gateway process:

   ```bash
   openclaw hooks list
   # Should show: 🎯 my-hook ✓
   ```

**Benefits of migration**:

- Automatic discovery
- CLI management
- Eligibility checking
- Better documentation
- Consistent structure
