Checks PRs against decisions your team approved in Slack
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.
We built this after it happened to us — a decision made in Slack
didn't make it into the code, and nobody caught it until a customer
hit it in production.
The frustrating part wasn't the bug. It was that the decision was
right there in #product-decisions. The PR just never got checked
against it.
Mo is the connection that was missing. Happy to answer any questions
about how the decision matching works under the hood.

Who hunted Mo?
Mo was hunted by Oscar Caldera. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
