Roomote vs Building Your Own
The model call is the easy 10%. Roomote is the other 90%.
Wiring Slack to a coding agent looks tractable from a demo. The model call is the easy 10%; the rest is context, permissions, verification, previews, audit trail, and the slow maintenance of a half-finished internal tool. Roomote is what teams build toward and rarely arrive at. If a homegrown version has been on your team's 'we should clean this up someday' list for six months, you've already paid for Roomote in opportunity cost.
Choose Building Your Own when
You have a strong internal tools engineer and the runway to maintain a non-trivial internal system as a strategic capability.
Choose
when
You'd rather your senior engineers spend their time on the product, not on the internal tool meant to give them more time for the product.
