Prepare ClickHouse context for new channels
Give every new project channel a useful data starting point on day one.
Trigger
New Channel Created Trigger
Triggered when a new channel is created in Slack.
Action
Get Database Schema
Get comprehensive schema overview of an entire database including all tables and optionally their column definitions. essential for ai agents to understand the complete database structure in a single call.
Why this helps
New channels often lack the data context needed to make early decisions.
- Reduce onboarding friction
- Create consistent project context
- Help teams find relevant data sooner
Setup
Build it in a few focused steps.
- 1Connect Slackbot and ClickHouse in Notis once.
- 2Create an automation and describe how to infer the channel purpose from its name or first message.
- 3Tell Notis to return a concise database overview relevant to that context.
- 4Pick New Channel Created as the trigger.
- 5Choose the report destination and test by creating one real channel.
Questions about this workflow
What if the channel name is vague?
Tell the automation to request a short purpose statement before choosing a database overview.
Will it post in the new channel?
Run reports go wherever you select during setup; the prompt can specify the desired destination.
