Confirmation message for Depends-On:

Expected Behavior

Sometimes the changes for feature/B depend on the changes for feature/A. The Depends-On: #1234 syntax allows me to block merging feature/B until the PR for feature/A merges, but a small typo can make that fail silently.

It would be nice if there was an obvious user-facing confirmation that Depends-On: was parsed successfully. One option would be to post a comment, like the existing "Mergify rebased successfully" comment. Another option would be an emoji on the PR description, like what is done when commenting "@mergifyio rebase".

Actual Behavior

depends-on: #1234, depends on: #1234, Depends-On #1234 etc don't create a dependency, but look correct at first glance.

Steps to Reproduce the Problem

1. Create two PRs
2. Add Depends-On: #1 to PR #2, but get the syntax wrong
3. Approve PR #2 and watch it merge automatically

• Mergify Config URL:

Start by tracing how the Depends-On: #1234 syntax is parsed and compare it with the existing “Mergify rebased successfully” comment and @mergifyio rebase emoji behavior. Done means a visibly user-facing confirmation appears when a dependency is parsed successfully, while malformed variants do not silently pass.
