The #1 support issue with Slack is 'bot works in DMs but not channels'.
This is almost always caused by missing event subscriptions (message.channels,
message.groups) or missing OAuth scopes (channels:history, groups:history).
Changes:
- slack.md: Move channels:history and groups:history from optional to required
scopes. Move message.channels and message.groups to required events. Add new
'How the Bot Responds' section explaining DM vs channel behavior. Add Step 8
for inviting bot to channels. Expand troubleshooting table with specific
'works in DMs not channels' entry. Add quick checklist for channel debugging.
- setup.py: Expand Slack setup wizard with all required scopes, event
subscriptions, and a warning that without message.channels/message.groups
the bot only works in DMs. Add link to full docs. Improve Member ID
discovery instructions.
- config.py: Update SLACK_BOT_TOKEN and SLACK_APP_TOKEN descriptions to list
required scopes and event subscriptions inline.
