Check for an existing CustomGPT project first
Find what is already available before anyone starts rebuilding it.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
List CustomGPT Projects
Tool to list all CustomGPT agents. Use when you need to retrieve agent projects with pagination support after setting your API key.
Why this helps
Teams can spend time planning a duplicate agent because project discovery is a separate manual step.
- Makes project discovery part of the conversation.
- Reduces avoidable duplicate exploration.
- Provides a current project list to inform next steps.
Setup
Build it in a few focused steps.
- 1Connect Slack and CustomGPT to Notis once in the portal.
- 2Create an automation in the portal or ask Notis conversationally.
- 3Describe in one instruction that channel questions about existing agents should retrieve the CustomGPT project list for review.
- 4Pick the Channel Message Received trigger and select a run-report channel.
- 5Test with a channel question about whether a named type of agent already exists.
Questions about this workflow
Does it search project contents?
No. The available action lists projects; it does not search their underlying knowledge or content.
Can it guarantee there is no duplicate?
It can show the project list for a person to review, but it does not infer project purpose from unavailable content.
