+    Tool-progress preview updates are the short "Working..." lines shown while tools run, for example command execution, file reads, planning updates, or patch summaries. Telegram keeps these enabled by default to match released OpenClaw behavior from `v2026.4.22` and later. To keep the edited preview for answer text but hide tool-progress lines, set:

+    ```json
+    {

+    }
+    ```
+
+    Use `streaming.mode: "off"` only when you want to disable Telegram preview edits entirely. Use `streaming.preview.toolProgress: false` when you only want to disable the tool-progress status lines.

 Supported surfaces:
 
-- **Discord** and **Slack** stream tool-progress into the live preview edit by default.
-- **Telegram** only streams tool-progress into the live preview edit when `streaming.preview.toolProgress` is explicitly enabled.
+- **Discord**, **Slack**, and **Telegram** stream tool-progress into the live preview edit by default when preview streaming is active.
+- Telegram has shipped with tool-progress preview updates enabled since `v2026.4.22`; keeping them enabled preserves that released behavior.
 - **Mattermost** already folds tool activity into its single draft preview post (see above).
 - Tool-progress edits follow the active preview streaming mode; they are skipped when preview streaming is `off` or when block streaming has taken over the message.
+- To keep preview streaming but hide tool-progress lines, set `streaming.preview.toolProgress` to `false` for that channel. To disable preview edits entirely, set `streaming.mode` to `off`.
