Adds Telegram's native streaming-draft API as a streaming transport so DM
replies render with smooth animated previews as tokens arrive, dropping
the per-edit jitter of the legacy editMessageText polling path.
Adapter contract (gateway/platforms/base.py):
- supports_draft_streaming(chat_type, metadata) -> bool. Default False.
Telegram returns True only for DMs and only when the bound python-
telegram-bot version exposes Bot.send_message_draft (PTB 22.6+).
- send_draft(chat_id, draft_id, content, metadata) -> SendResult.
Default raises NotImplementedError. Telegram delegates to PTB's
send_message_draft. Drafts have no message_id (Bot API contract);
SendResult.message_id is None on success.
Telegram adapter (gateway/platforms/telegram.py):
- supports_draft_streaming gates on chat_type='dm' AND PTB capability.
- send_draft trims to MAX_MESSAGE_LENGTH using utf16_len, threads
message_thread_id through metadata, and routes failures back as
SendResult(success=False, error=...) so the consumer can fall back.
Stream consumer (gateway/stream_consumer.py):
- StreamConsumerConfig gains transport ('auto'|'draft'|'edit'|'off')
and chat_type fields.
- run() resolves _use_draft_streaming once via a probe at the top of
the run, allocating a fresh class-wide draft_id_counter so each
response animates as its own preview (no animation collision across
consecutive responses to the same chat).
- _send_or_edit gains a pre-edit branch: when drafts are active AND
not finalizing AND no edit-path message_id is established, the
frame routes through _send_draft_frame instead of edit_message.
Drafts intentionally do NOT set _already_sent so the gateway's
final sendMessage path still fires — drafts have no message_id and
the user needs a real message in their chat history.
- _reset_segment_state bumps the draft_id when the consumer is in
draft mode so each text block after a tool boundary animates as a
fresh preview below the tool-progress bubble (avoids the inter-
tool-call leak openclaw documented in their #32535).
- Per-response fallback: any send_draft failure (transient network,
server reject, capability gap) flips _use_draft_streaming to False
for the rest of the run, gracefully returning to the edit path.
Gateway config (gateway/config.py):
- StreamingConfig.transport default flips edit -> auto. The auto path
is identical to edit on every chat type that doesn't currently
support drafts (groups, supergroups, forum topics, every non-
Telegram platform), so the default is backwards-compatible for
non-DM users.
Lifecycle model (Telegram Bot API 9.5):
1. sendMessageDraft(chat_id, draft_id, text='') opens the bubble.
2. Repeated sendMessageDraft calls with the SAME draft_id animate
the preview as text grows.
3. Drafts have no message_id and cannot be edited or deleted.
4. When the response finishes the gateway's normal sendMessage path
delivers the final answer; the draft preview clears naturally on
the client and the user sees a real message in their history.
Inspired by PR #3412 by @NivOO5. Re-authored against current main
(stream_consumer.py is now ~4x larger than at #3412's branch base, with
new _NEW_SEGMENT/_COMMENTARY/finalize/_on_new_message machinery the
original PR didn't account for) but the design call (DM-only, edit-
fallback, transport=auto|draft|edit|off) is faithful to the original
proposal, with two improvements baked in:
1. Per-response draft_id (monotonic counter, not a time hash) — no
collision risk across consecutive responses on the same chat.
2. Tool-boundary draft_id bump — prevents the inter-tool-call leak
openclaw hit during their rollout (their #32535).
Closes #21439 (duplicate feature request).

Merged via salvage PR #23512 (#23512). Re-authored against current main since stream_consumer.py is now ~4x larger than at your branch base, with new state machine pieces (_NEW_SEGMENT, _COMMENTARY, finalize, _on_new_message) that the original cherry-pick wouldn't have accounted for. Your authorship is preserved on the substantive commit (re-attributed from your local hostname-derived git config to your GitHub noreply). The design call (DM-only, edit-fallback, transport=auto|draft|edit|off) stays faithful to your proposal, with two improvements based on openclaw's rollout experience: per-response monotonic draft_id counter (no collision risk vs your time.monotonic() hash), and tool-boundary draft_id bump to dodge the inter-tool-call leak openclaw documented in their #32535. Also added regression tests and docs. Thanks for the feature! |

not finalizing AND no edit-path message_id is established, the
frame routes through _send_draft_frame instead of edit_message.
Drafts intentionally do NOT set _already_sent so the gateway's
final sendMessage path still fires — drafts have no message_id and
the user needs a real message in their chat history.
- _reset_segment_state bumps the draft_id when the consumer is in
draft mode so each text block after a tool boundary animates as a
fresh preview below the tool-progress bubble (avoids the inter-
tool-call leak openclaw documented in their NousResearch#32535).
- Per-response fallback: any send_draft failure (transient network,
server reject, capability gap) flips _use_draft_streaming to False
for the rest of the run, gracefully returning to the edit path.
Gateway config (gateway/config.py):
- StreamingConfig.transport default flips edit -> auto. The auto path
is identical to edit on every chat type that doesn't currently
support drafts (groups, supergroups, forum topics, every non-
Telegram platform), so the default is backwards-compatible for
non-DM users.
Lifecycle model (Telegram Bot API 9.5):
1. sendMessageDraft(chat_id, draft_id, text='') opens the bubble.
2. Repeated sendMessageDraft calls with the SAME draft_id animate
the preview as text grows.
3. Drafts have no message_id and cannot be edited or deleted.
4. When the response finishes the gateway's normal sendMessage path
delivers the final answer; the draft preview clears naturally on
the client and the user sees a real message in their history.
Inspired by PR NousResearch#3412 by @NivOO5. Re-authored against current main
(stream_consumer.py is now ~4x larger than at NousResearch#3412's branch base, with
new _NEW_SEGMENT/_COMMENTARY/finalize/_on_new_message machinery the
original PR didn't account for) but the design call (DM-only, edit-
fallback, transport=auto|draft|edit|off) is faithful to the original
proposal, with two improvements baked in:
1. Per-response draft_id (monotonic counter, not a time hash) — no
collision risk across consecutive responses on the same chat.
2. Tool-boundary draft_id bump — prevents the inter-tool-call leak
openclaw hit during their rollout (their NousResearch#32535).
Closes NousResearch#21439 (duplicate feature request).

Adds Telegram's native streaming-draft API as a streaming transport so DM
replies render with smooth animated previews as tokens arrive, dropping
the per-edit jitter of the legacy editMessageText polling path.
Adapter contract (gateway/platforms/base.py):
- supports_draft_streaming(chat_type, metadata) -> bool. Default False.
Telegram returns True only for DMs and only when the bound python-
telegram-bot version exposes Bot.send_message_draft (PTB 22.6+).
- send_draft(chat_id, draft_id, content, metadata) -> SendResult.
Default raises NotImplementedError. Telegram delegates to PTB's
send_message_draft. Drafts have no message_id (Bot API contract);
SendResult.message_id is None on success.
Telegram adapter (gateway/platforms/telegram.py):
- supports_draft_streaming gates on chat_type='dm' AND PTB capability.
- send_draft trims to MAX_MESSAGE_LENGTH using utf16_len, threads
message_thread_id through metadata, and routes failures back as
SendResult(success=False, error=...) so the consumer can fall back.
Stream consumer (gateway/stream_consumer.py):
- StreamConsumerConfig gains transport ('auto'|'draft'|'edit'|'off')
and chat_type fields.
- run() resolves _use_draft_streaming once via a probe at the top of
the run, allocating a fresh class-wide draft_id_counter so each
response animates as its own preview (no animation collision across
consecutive responses to the same chat).
- _send_or_edit gains a pre-edit branch: when drafts are active AND
not finalizing AND no edit-path message_id is established, the
frame routes through _send_draft_frame instead of edit_message.
Drafts intentionally do NOT set _already_sent so the gateway's
final sendMessage path still fires — drafts have no message_id and
the user needs a real message in their chat history.
- _reset_segment_state bumps the draft_id when the consumer is in
draft mode so each text block after a tool boundary animates as a
fresh preview below the tool-progress bubble (avoids the inter-
tool-call leak openclaw documented in their NousResearch#32535).
- Per-response fallback: any send_draft failure (transient network,
server reject, capability gap) flips _use_draft_streaming to False
for the rest of the run, gracefully returning to the edit path.
Gateway config (gateway/config.py):
- StreamingConfig.transport default flips edit -> auto. The auto path
is identical to edit on every chat type that doesn't currently
support drafts (groups, supergroups, forum topics, every non-
Telegram platform), so the default is backwards-compatible for
non-DM users.

Summary
send_message_draftstreaming support for DM chatstransport: auto|draft|edit|offWhy
Telegram now exposes a native draft streaming API that renders progressively in supported clients much better than repeated
editMessageTextupdates. Hermes currently uses edit-based streaming only, which can appear as a single final chunk for Telegram users even when OpenClaw/native draft streaming works in the same client.This patch adds the safer first step:
Implementation details
StreamingConfig.transportnow defaults toautoGatewayStreamConsumerchoosesdraftonly when:autoor explicitlydraftdmalready_sent=true, so the normal final send path still delivers the completed messageTest plan
Result locally:
Risk / scope
This intentionally does not replace Hermes' global streaming implementation.
It adds a DM-only optimization with edit fallback, which keeps the blast radius modest while letting Telegram private chats take advantage of the newer API.
