Built this after a recurring frustration at our agency: the team would agree on something in Slack ("only admins can export users"), someone would open a PR two weeks later that quietly broke it, and nobody caught it until QA or after deploy.Mo watches a Slack channel for decisions. When someone tags @mo to approve something, it stores it. When a PR opens, Mo checks the diff against the approved decisions and flags conflicts before merge.It doesn't review code quality. It only cares whether the code matches what the team actually agreed to.Would love feedback, especially from anyone who's been burned by this exact problem.Try it here: https://hey-mo.io

Could you build this?
Yes It listens to Slack messages via webhooks to store team decisions, then runs an LLM evaluation on GitHub PR diffs against those saved decisions using GitHub Actions or webhooks.
