Group DMs (multi-person DMs, channel_type=mpim) were never delivered to
the Slack bot. The adapter already classifies mpim as a DM and replies
ambiently (adapter.py:2526, is_dm = channel_type in {im, mpim}), but the
generated app manifest only subscribed to message.im / im:history — the
1:1 DM pair. Without the message.mpim event subscription Slack drops
group-DM messages before the adapter ever sees them, so 1:1 DMs worked
while group-DM ambient mode was dead.
Add message.mpim to bot_events and mpim:history (the scope that event
requires per Slack docs) + mpim:read (mirrors im:read for the
conversations.info classification call) to bot_scopes. Update the
SLACK_BOT_TOKEN / SLACK_APP_TOKEN setup-help strings and the Slack docs
(EN + zh-Hans: scope table, event table, troubleshooting) so existing
installs are told to add the new scopes and reinstall.
Reported by an enterprise customer. Note: this is a manifest/scope
change, so it only takes effect after the app is reinstalled and the
new scopes are accepted.
Tests: assert message.mpim + mpim:history + mpim:read are in the
manifest (with and without assistant mode); both fail on current main
and pass with this change.
By default `hermes slack manifest` opts the app into Slack's AI Assistant
container (assistant_view feature + assistant:write scope +
assistant_thread_* events). Slack then renders DMs as the right-hand
Assistant split-pane, where every exchange is a thread and bare slash
commands (/help, /new, ...) are not delivered as normal command events —
they only work when the bot is @mentioned. There was no way to opt out
short of hand-editing the generated JSON.
Add --no-assistant to emit a flat-DM manifest that omits those three
pieces, so DMs render as a normal chat and slash commands dispatch
inline. The regular messaging surface (Messages tab, slash commands,
Socket Mode, channel + DM scopes/events) is preserved in both modes.
Default behaviour is unchanged (assistant mode still on).
Tests: cover both manifest modes and the argparse wiring.
