AI / Dependabot Interview questions
What triggers Dependabot to create a pull request?
Two distinct triggers exist, matching Dependabot's two core features. For version updates, the trigger is simply the scheduled check (daily/weekly/monthly, per your configuration) finding that a newer version of a monitored dependency is available. For security updates, the trigger is the dependency graph matching against a newly published (or newly relevant) entry in the GitHub Advisory Database.

A[Scheduled check per dependabot.yml] --> B{Newer version available?}
B -->|Yes| C[Version update PR opened]
D[New security advisory published] --> E{Repo depends on affected version?}
E -->|Yes| F[Security update PR opened]
Security update PRs can appear at any time, independent of your configured schedule, since they're event-driven by advisory publication rather than tied to a fixed check interval — a genuinely critical vulnerability doesn't wait for your next scheduled weekly check to be addressed.
