Mo is a developer tool that ensures code changes align with team decisions made in Slack. Mo connects to Slack and your Git provider (GitHub or GitLab) to capture approved decisions and automatically checks pull/merge requests against them. When a PR conflicts with a documented decision, Mo flags it before merge—helping teams prevent misalignment, rework, and unintended behavior. Instead of relying on memory or manual reviews, Mo creates a lightweight layer of enforcement between product decisions and code execution. It focuses specifically on decision consistency, not code quality, making it a complementary tool to existing code review workflows. Mo is designed for teams that use Slack to discuss and approve product or technical decisions and want to ensure those decisions are consistently reflected in their codebase.
