## What this automation is

This is a two-part setup: a chat assistant you have already trained on your own material, and a bridge that lets a Slack channel talk to it. The bridge runs as an automation scenario. A message posted in the channel triggers the scenario, the scenario sends the text to the assistant, and the reply comes back into the same thread.

You are not building a chatbot from nothing. The assistant is the part that holds your knowledge: policies, product notes, internal definitions, whatever you feed it. The automation is the wiring. Keeping those two pieces separate makes the whole thing easier to maintain, because you can retrain the assistant without touching the channel setup, and you can change channels without rebuilding the training.

## When to use it

Use it when a team keeps answering the same questions in chat. A support channel where people ask how refunds work. An onboarding channel where new hires ask where things live. A project channel where the answer is buried in a document nobody opens.

It is a poor fit for anything sensitive. Do not point it at a channel where people discuss customer data, credentials or confidential plans, because every message sent to the assistant leaves your workspace. It is also a poor fit for fast-moving decisions, since the assistant answers from what it was trained on, not from the conversation happening right now.

## How to set it up

1. Finish the assistant first. Train it, test it with twenty or so real questions, and fix the answers that come back vague or wrong. A weak assistant will stay weak no matter how clean the automation is.
2. Decide which channel it serves and who is allowed to trigger it. A single purpose channel works better than a general one, because you can train the assistant on material that matches that purpose.
3. Create the automation scenario and connect your Slack account. Grant it permission to read messages and post replies in the channel you chose.
4. Set the trigger to fire on new messages in that channel. Filter out bot messages and your own replies so the assistant cannot answer itself in a loop.
5. Add the step that calls your assistant, passing the message text as the input. Map the answer field to the next step.
6. Post the answer back into the channel, ideally as a threaded reply so the main feed stays readable.
7. Run one test message end to end, then a second one with a question you know the assistant handles badly. Confirm the failure mode is a polite fallback rather than a wrong answer stated with confidence.

## What a good result looks like

Someone asks a question in the channel and gets a short, correct answer in the thread within a few seconds, without pinging a colleague. The assistant says it does not know when it does not know. Threads stay tidy, and the channel feed is not flooded with bot output.

Keep a short list of questions the assistant got wrong and retrain on those. That loop, run monthly, matters more than any setting in the scenario.
