PRereq

Hold the merge
until the prerequisites
land.

PRereq reads depends on #88 from your pull requests and posts a check that won't go green until every PR it needs has merged. Stacked work ships in the right order — on its own.

Four steps. Then it's just there.

The order matters, so the layout follows it — a single dependency line threaded through the whole flow.

  1. 01

    Write the dependency

    Drop “depends on acme/db#88” in your PR description — cross-repo refs welcome. Say it however your team already talks: blocked by, requires, needs.

  2. 02

    PRereq posts a check

    The moment the PR opens, a required status check named prereq/dependencies appears alongside your build and tests.

  3. 03

    The merge holds

    While any prerequisite is still open, the check stays red and GitHub won’t let the pull request merge. No accidental out-of-order landings.

  4. 04

    It clears itself

    Merge the PRs it depends on and the check turns green on its own. No re-runs, no comments to type, no babysitting.

Small check. Strong guarantees.

Cross-repo dependencies

Depend on a PR in any other repository. Just state the repo name and PR number and PRereq will find it.

Cycle detection

If two PRs end up waiting on each other, PRereq names the loop instead of quietly deadlocking your merges.

Reads your words

No new syntax to learn, just tell PRereq how your team expresses dependencies.

Enforced, not advisory

PRereq is a status check. Add it to your required checks and the merge order becomes a rule, not a reminder.

One install, every repo

Install once on the organization. New repositories are picked up automatically.

Fair metering

You're only counted for checks that actually enforce a dependency. A pull request with no prerequisites is free.

Priced by enforced checks.

Every plan is unlimited repositories and unlimited people. The only meter is how many times a dependency actually holds a merge.
