+- Agents/Replies: stop emitting synthetic completion acknowledgements for tool-only runs with no final assistant text, so no extra `✅ Done.` message is injected.

(#23359) Thanks @goren-beehero.

+# Synology Chat (plugin)
+
+Status: supported via plugin as a direct-message channel using Synology Chat webhooks.
+The plugin accepts inbound messages from Synology Chat outgoing webhooks and sends replies
+through a Synology Chat incoming webhook.
+
+## Plugin required
+
+Synology Chat is plugin-based and not part of the default core channel install.
+
+Install from a local checkout:
+
+```bash
+openclaw plugins install ./extensions/synology-chat
+```
+
+Details: [Plugins](/tools/plugin)
+
+## Quick setup
+
+1. Install and enable the Synology Chat plugin.
+2. In Synology Chat integrations:
+   - Create an incoming webhook and copy its URL.
+   - Create an outgoing webhook with your secret token.
+3. Point the outgoing webhook URL to your OpenClaw gateway:
+   - `https://gateway-host/webhook/synology` by default.
+   - Or your custom `channels.synology-chat.webhookPath`.
+4. Configure `channels.synology-chat` in OpenClaw.
+5. Restart gateway and send a DM to the Synology Chat bot.
+
+Minimal config:
+
+```json5
+{
+  channels: {
+    "synology-chat": {
+      enabled: true,
+      token: "synology-outgoing-token",
+      incomingUrl: "https://nas.example.com/webapi/entry.cgi?api=SYNO.Chat.External&method=incoming&version=2&token=...",
+      webhookPath: "/webhook/synology",
+      dmPolicy: "allowlist",
+      allowedUserIds: ["123456"],
+      rateLimitPerMinute: 30,
+      allowInsecureSsl: false,
+    },
+  },
+}
+```
+
+## Environment variables
+
+For the default account, you can use env vars:
+
+- `SYNOLOGY_CHAT_TOKEN`
+- `SYNOLOGY_CHAT_INCOMING_URL`
+- `SYNOLOGY_NAS_HOST`
+- `SYNOLOGY_ALLOWED_USER_IDS` (comma-separated)
+- `SYNOLOGY_RATE_LIMIT`
+- `OPENCLAW_BOT_NAME`
+
+Config values override env vars.
+
+## DM policy and access control
+
+- `dmPolicy: "allowlist"` is the recommended default.
+- `allowedUserIds` accepts a list (or comma-separated string) of Synology user IDs.
+- `dmPolicy: "open"` allows any sender.
+- `dmPolicy: "disabled"` blocks DMs.
+- Pairing approvals work with:
+  - `openclaw pairing list synology-chat`
+  - `openclaw pairing approve synology-chat <CODE>`
+
+## Outbound delivery
+
+Use numeric Synology Chat user IDs as targets.
+
+Examples:
+
+```bash
+openclaw message send --channel synology-chat --target 123456 --text "Hello from OpenClaw"
+openclaw message send --channel synology-chat --target synology-chat:123456 --text "Hello again"
+```
+
+Media sends are supported by URL-based file delivery.
+
+## Multi-account
+
+Multiple Synology Chat accounts are supported under `channels.synology-chat.accounts`.
+Each account can override token, incoming URL, webhook path, DM policy, and limits.
+
+```json5
+{
+  channels: {
+    "synology-chat": {
+      enabled: true,
+      accounts: {
+        default: {
+          token: "token-a",
+          incomingUrl: "https://nas-a.example.com/...token=...",
+        },
+        alerts: {
+          token: "token-b",
+          incomingUrl: "https://nas-b.example.com/...token=...",
+          webhookPath: "/webhook/synology-alerts",
+          dmPolicy: "allowlist",
+          allowedUserIds: ["987654"],
+        },
+      },
+    },
+  },
+}
+```
+
+## Security notes
+
+- Keep `token` secret and rotate it if leaked.
+- Keep `allowInsecureSsl: false` unless you explicitly trust a self-signed local NAS cert.
+- Inbound webhook requests are token-verified and rate-limited per sender.
+- Prefer `dmPolicy: "allowlist"` for production.
