GitLab Business Rule Checks

Protect important product rules inside GitLab merge requests.

Mo checks GitLab merge requests against approved business rules before merge. Teams use it to catch pricing drift, permission changes, onboarding flow issues, and other risky logic changes before they ship.

Works with Slack and GitLab. No separate review workflow required.

CONFLICT WITH APPROVED RULE

GitLab catches a lot. Mo catches a different kind of mistake.

GitLab can tell you if the pipeline passed.
Mo tells you if the merge request still follows an approved business rule.

That difference matters when the code is technically valid but the product behavior is wrong.

What GitLab teams use Mo for

Rule area

What changes

What Mo flags

Pricing

Trial duration, discount logic, plan access

Merge requests that change approved pricing behavior

Permissions

Role access, exports, billing visibility

Merge requests that widen access beyond what was approved

Onboarding

Activation steps, confirmations, approval gates

Merge requests that skip required onboarding logic

Sensitive workflows

Verification, restrictions, approvals

Merge requests that remove or bypass important controls

How it fits a GitLab workflow

Slack

Approve the rule where the conversation happens

→

GitLab MR

Developer opens the MR normally

→

Mo check

Mo reads the MR and compares it against approved rules

→

Before merge

If the rule is broken, the MR is flagged

Examples of business rules teams check in GitLab

Trial period must stay at 7 days

Only admins can export users

Guest accounts cannot view billing

Verification must complete before payout activation

Restricted regions cannot access this feature

Support users cannot delete customer accounts

Approval is required before partner activation

Premium features remain disabled until onboarding is complete

Why merge-request review is not enough

Merge-request review is good at catching implementation issues.

It is much worse at catching logic that quietly drifted away from what product, ops, or leadership approved.

Mo adds a merge-time check for exactly that.

Designed for teams that already live in GitLab

Fast-moving teams

Fast-moving product teams

Where review speed matters and small logic changes can have big downstream effects.

AI-assisted teams

AI-assisted development teams

Where more code is generated and less product logic is held in one reviewer's head.

Approval-heavy products

Ops-heavy or approval-heavy products

Where merge requests can affect sensitive flows, restricted access, or customer-visible rules.

Slack-first input. GitLab-level enforcement.

Teams do not need to move rule definition into another system just to protect a few important behaviors. Slack stays the easiest place to approve rules. GitLab stays the place where merge decisions are enforced.

When needed, rules can also be added from uploaded documents.
