Slack to GitHub Rule Checks

Approve in Slack.
Check in GitHub.

Mo turns approved rules and decisions from Slack into GitHub pull request checks. No new process, no separate review workflow, and no need to move the team into another tool.

Slack stays the input. GitHub stays the checkpoint.

CONFLICT WITH APPROVED RULE

Most teams already approve things in chat.

Slack is where teams clarify product behavior, settle edge cases, approve exceptions, and lock in rules that matter. The problem is not approval. The problem is that those approvals usually stop at the conversation.

Mo carries them into GitHub.

Why teams use Slack first

Why Slack works
Fast
Already used every day
Easy to involve product and engineering
Easy to approve a rule in context
No extra system to maintain
What usually goes wrong
Decision stays in the thread
Pull request is opened later
Reviewer does not know the rule exists
Code ships something different
Nobody notices until later

What this looks like in practice

Pricing
Slack rule

"Trial must stay at 7 days."

GitHub check
Flags the pull request when trial logic changes to 14 days.
Permissions
Slack rule

"Guest users cannot see billing."

GitHub check
Flags the pull request when guest visibility is expanded.
Onboarding
Slack rule

"Users must confirm email before starting a trial."

GitHub check
Flags the pull request when trial access is enabled earlier.

No new workflow for the team

Product or engineering approves a rule in Slack. Developers keep using GitHub normally. Mo runs as part of the pull request process and flags drift before merge.

No extra planning tool.
No separate review queue.
No requirement to rewrite how the team works.

How it works

Slack Slack
Input
@mo approve this

Approve a rule or decision in any Slack channel.

Mo Mo
Bridge
Rule captured

Stores the approved rule and prepares it for code checks.

GitHub GitHub
Checkpoint
PR check

Checks pull requests against approved rules before merge.

Optional
Documents
Upload path

Teams can add rules from a document. Mo provides an upload path and lets the team approve what should be enforced.

Why Slack to GitHub is the simplest starting point

Most teams do not want to adopt another management layer just to protect a few important rules. Slack already holds the conversations. GitHub already holds the merge point.

Mo connects the two.

That is why teams can start small and still get value quickly.

Who this is for

01
Teams shipping quickly

Where review speed makes it easy to miss rule drift.

02
Teams using AI coding tools

Where more code is being generated and approvals are easier to lose.

03
Product-led teams

Where important behavior decisions are often made in Slack.

04
Teams that do not want another process

Where adoption only works if the workflow stays lightweight.

FAQ

Do we have to use the Mo portal?

No. Slack is the primary way teams approve rules and decisions. The portal is secondary and mainly useful for uploads or additional setup.

Can non-developers approve rules in Slack?

Yes. Product, ops, founders, and engineering leads can approve rules where the conversation already happens.

Does this work only for GitHub?

No. Mo also works with GitLab merge requests.

Do we need to approve every message?

No. Only what is explicitly approved becomes enforceable.

Keep Slack as the place where rules are approved.

Let GitHub be the place where those rules are checked.

Mo turns approved Slack rules into GitHub pull request checks. No new process. No new tool.
