Mo

Checks PRs against decisions your team approved in Slack

Website hey-mo.io

What it is

Your team agrees on something in Slack. Two weeks later a PR quietly breaks it. Nobody catches 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 every approved decision and flags conflicts before merge. It doesn't review code quality. It only cares if the code matches what the team actually decided.

Intent

I need it when

Maintain compliance and onboarding flow integrity by catching deviations from approved product behavior before release

Mo enforces onboarding steps, compliance gates, and product decisions approved in Slack. When a PR removes an email verification step, bypasses a region restriction, or changes guest user access, Mo flags it immediately with the source rule and exact code change, ensuring approved behavior stays intact.

Prevent pricing rule drift and catch trial, discount, or entitlement logic changes before they ship to production

Mo captures pricing rules approved in Slack (e.g., 'Trial must stay at 7 days') and automatically checks every GitHub or GitLab pull request before merge. If code changes pricing logic in violation of the approved rule, Mo flags the PR with the exact conflict, file, and line number, blocking merge until the rule is restored.

Audit and trace which decisions were approved, by whom, and what code changes violated them for compliance and accountability

Mo maintains a full audit trail of every approved rule, including who approved it, when, and all change history. The Mo portal shows decision history, conflict logs, and PR alignment. Each PR conflict links back to its source Slack message or document, providing complete traceability for compliance and post-incident review.

Enforce permission and access control decisions so unauthorized role or feature access changes don't ship unnoticed

Mo stores permission rules approved in Slack (e.g., 'Only admins can export users') and detects when pull requests remove role checks or widen access. It posts inline PR comments showing the approved rule, the detected violation, and who approved it, preventing access drift before merge.

Turn Slack conversations and written policies into enforceable merge checks without adding new tools or workflows

Mo integrates directly into Slack (@Mo approve this) and GitHub/GitLab without requiring developers to change their workflow. Teams approve rules where decisions already happen, and Mo automatically checks every PR. Rules can also be extracted from uploaded PDFs or documents, making enforcement lightweight and non-disruptive.

Drop

Not a fit when

Team does not use Slack for decision-making or approval workflows
Organization uses only Bitbucket or other code hosts not supported (Mo only checks GitHub PRs, GitLab MRs, and Bitbucket PRs)
Team needs code quality, syntax, or security vulnerability detection rather than business rule enforcement
Rules cannot be expressed in natural language or violations are not detectable in code diffs (runtime-only behavior)
Organization requires per-seat pricing or needs more than 20 approved decisions and 100 PR checks per month without custom arrangement
