FAQ

Questions about Slack + OpenAI.

How do I build a GPT bot in Slack?

Slack App Mentioned → fetch recent channel history → OpenAI Chat Completion → Slack Reply in Thread. Bot answers when @-mentioned in channels it's in.

Can GPT summarize Slack threads?

Yes. Slash command /summarize → Get Thread Replies → OpenAI summarizes → reply as ephemeral message visible only to requester.

How do I give GPT internal-doc knowledge (RAG)?

Index Notion/Confluence/Drive into vector store. On question, retrieve top-3 docs, pass to GPT as context with "answer only from these". Cite sources in reply.

Can GPT triage support requests in #help channels?

Yes. New message in #help → OpenAI classifies (urgency + team) → either answer if confident, or @-mention the right team with summary. Async-team time-saver.

How do I avoid GPT responding to bot messages?

Filter Slack trigger to skip messages with subtype = "bot_message" and skip own bot user. Otherwise the bot loops on its output indefinitely.

Can I use GPT tool-calling to take actions from Slack?

Yes. Define tools (create_jira_issue, search_docs, update_record). GPT decides which to call based on user message. Workflow executes calls + feeds results back.
