channels.<channel>.streaming.mode: "progress" and OpenClaw creates the
message once real work starts, edits it as the agent reads, plans, calls
tools, or waits for approval, then turns it into the final answer.
Discord already defaults to
streaming.mode: "progress" when
channels.discord.streaming.mode/streamMode are unset, so progress drafts
show up there without any config. Every other channel defaults to partial
or off; see Streaming and chunking
for the full per-channel default table.Quick start
What users see
| Part | Purpose |
|---|---|
| Label | Short starter/status line such as Working or Shelling. |
| Progress lines | Compact run updates using the same tool icons and detail formatter as /verbose. |
🛠️ Bash: run tests,
🔎 Web Search: for "discord edit message", or ✍️ Write: to /tmp/file.
The final answer replaces the draft in place when the channel can safely do
that; otherwise OpenClaw sends the final answer through normal delivery and
cleans up or stops updating the draft (see Finalization).
Choose a mode
channels.<channel>.streaming.mode controls the visible in-progress behavior:
| Mode | Best for | What appears in chat |
|---|---|---|
off | Quiet channels | Only the final answer. |
partial | Watching answer text appear | One draft edited with the latest answer text. |
block | Larger answer-preview chunks | One preview updated or appended in bigger chunks. |
progress | Tool-heavy or long-running turns | One status draft, then the final answer. |
progress when users care more about “what is happening” than watching
answer text stream token by token; partial when the answer text itself is
the progress signal; block for larger preview chunks. On Discord and
Telegram, streaming.mode: "block" is still preview streaming, not normal
block-reply delivery — use streaming.block.enabled (or legacy
blockStreaming) for that.
Configure labels
Progress labels live underchannels.<channel>.streaming.progress. The
default label is "auto", which picks from OpenClaw’s built-in single-word
label pool:
label: "auto"):
Control progress lines
Progress lines come from real run events: tool starts, item updates, task plans, approvals, command output, patch summaries, and similar agent activity. They are enabled by default (progress.toolProgress, default true).
Tools can also emit typed progress while a single call is still running. That
is how a slow fetch or search updates the visible draft before the tool
returns its final result. The progress update is a partial tool result with
empty model content and explicit public channel metadata:
progress.text in the channel progress UI. The normal
tool result still arrives later as content/details and is the only part
returned to the model.
When adding progress to a tool, emit a short, generic message and delay it
until the operation has been pending long enough to be useful. web_fetch
does exactly this with a 5-second delay:
Detail mode
OpenClaw uses the same formatter for progress drafts and/verbose:
"explain" is the default and keeps drafts stable with concise labels.
"raw" appends the underlying command when available, which is useful while
debugging but noisier in chat. For example, a node --check /tmp/app.js call
renders differently by mode:
| Mode | Progress line |
|---|---|
explain | 🛠️ check js syntax for /tmp/app.js |
raw | 🛠️ check js syntax for /tmp/app.js · node --check /tmp/app.js |
Command/exec text
streaming.progress.commandText (default "raw") controls how much command
detail shows next to exec/bash progress lines, independent of the detail mode
above. Set it to "status" to keep a tool-progress line visible while hiding
the command text entirely:
Commentary lane
streaming.progress.commentary (default false) interleaves the model’s
pre-tool commentary/preamble narration (💬, for example “I’ll check… then
…”) with tool lines in the draft. See
Streaming and chunking for the
shared config shape across channels.
Line limits
Limit how many lines stay visible (default 8):Rich rendering (Slack)
Slack can render progress lines as structured Block Kit fields instead of plain text:Hide tool/task lines
Keep the single progress draft but hide tool and task lines:toolProgress: false, OpenClaw still suppresses the older standalone
tool-progress messages for that turn — the channel stays visually quiet until
the final answer, except for the label if one is configured.
Channel behavior
| Channel | Progress transport | Notes |
|---|---|---|
| Discord | Send one message, then edit it. | Defaults to progress mode; final text edits in place when it fits one safe preview message. |
| Matrix | Send one event, then edit it. | Account-level streaming config controls account-level drafts. |
| Microsoft Teams | Native Teams stream in personal chats. | streaming.mode: "block" maps to Teams block delivery instead. |
| Slack | Native stream or editable draft post. | Needs a reply thread target; top-level DMs without one still get draft preview posts and edits. |
| Telegram | Send one message, then edit it. | If a message lands between the progress draft and the answer, the draft reposts below it (post-new-then-delete-old) instead of scroll-jumping the client. |
| Mattermost | Editable draft post. | Tool activity folds into the same draft-style post. |
Finalization
When the final answer is ready, OpenClaw tries to keep the chat clean:- If the draft can safely become the final answer, OpenClaw edits it in place.
- If the channel uses native progress streaming, OpenClaw finalizes that stream when the native transport accepts the final text.
- Otherwise (media, an approval prompt, an explicit reply target, too many chunks, or a failed edit/send) OpenClaw sends the final answer through the normal channel delivery path instead of overwriting the draft.
Troubleshooting
I only see the final answer. Check thatchannels.<channel>.streaming.mode is progress for the account
or channel that handled the message. Some group or quote-reply paths disable
draft previews for a turn when the channel cannot safely edit the right
message.
I see the label but no tool lines.
Check streaming.progress.toolProgress. If it is false, OpenClaw keeps the
single draft behavior but hides tool and task progress lines.
I see a fresh final message instead of an edited draft.
That is the safety fallback described in Finalization. It can
happen for media replies, long answers, explicit reply targets, old Telegram
drafts, missing Slack thread targets, deleted preview messages, or failed
native stream finalization.
I still see standalone progress messages.
Progress mode suppresses default standalone tool-progress messages whenever a
draft is active. If standalone messages still appear, confirm the turn is
actually using progress mode and not streaming.mode: "off" or a channel
path that cannot create a draft for that message.
Teams behaves differently from Discord or Telegram.
Microsoft Teams uses a native stream in personal chats instead of the generic
send-and-edit preview transport, and maps streaming.mode: "block" to Teams
block delivery because it has no draft-preview block mode like Discord and
Telegram.
