# Slack Team HITL: Team Tool Confirmation (Simple)

> Simple port of AgentOS human_in_the_loop/team/team_tool_confirmation.py.

Slack Team HITL — Team Tool Confirmation (Simple)
==================================================

Simple port of AgentOS human_in_the_loop/team/team_tool_confirmation.py.

The confirmation-required tool is on the team itself (not a member agent).
When the team leader decides to use the tool, the run pauses and Slack shows
an Approve/Deny card.

Try in Slack:
  @bot deploy auth-service to production

Slack scopes: app_mentions:read, assistant:write, chat:write, im:history
