Mo

Ensure every merge matches what your team approved in Slack

April 8, 2026 I built Mo to stop PRs from breaking decisions made in Slack

So I built Mo. You invite it to a Slack channel, tag @mo to approve a decision, and Mo checks every PR against it before merge. If there's a conflict, it blocks the merge and shows exactly what was violated.

It doesn't review code quality. It only cares if the code matches what the team actually agreed to.

Would love feedback from anyone who's dealt with this and to know if this maps to how your team actually works.

We kept shipping code that contradicted decisions already made in Slack. The PR just never got checked against them. After it hit production one too many times, I built Mo to make that check automatic.
