#Slack triggers

#Events

on	Fires when
slack.mention	The bot is mentioned in a channel it has been invited to.

The mention is required. Direct messages, slash commands, and interactive components do not produce this trigger.

#Filters

Slack filters use IDs, not display names:

filters:
  workspace: T01234567
  channels: [C01234567]
  from_users: [U01234567]
  pattern: "repo="

from_users matches the author's Slack user id. workspace is the team id. channels matches the channel id. pattern (or contains) matches the start of the text after the mention. All filters must pass.

#Invocation

Put leading inputs directly after the mention:

@Paseo repo=project agent=claude investigate the failed sync

Hub consumes only declared consecutive headers and passes investigate the failed sync as ${{ paseo.prompt }}. See Hub workflows for input types, defaults, choices, and rejection behavior.

#Replies and workflow shape

Put the reply capability on a step:

allow_outputs:
  - type: slack.reply
    max: 5

The reply is posted in the triggering thread. A root message gets a new thread; a threaded message stays in that thread. Use the shared workflow examples for complete configurations.
