Setup
- Create or open a Switchy Project.
- Open Integrations and connect PromptLayer.
- Authorise through api_key. Switchy stores the connection against your org.
- Everyone in the Project can now @-mention the PromptLayer tools in chat.
What teammates see: by default, memories from PromptLayer are scoped to the Project (PROJECT visibility) - you can mark any memory PRIVATE or share it ORG-wide.
