understand what you shipped

Are you climbing above your protection?

You ship code faster than you can understand it. RUNOUT quizzes you on what your agents merged — and warns you before the 2am incident in code you don't actually grasp.

In climbing, the runout is the distance above your last piece of protection. Here: protection is understanding you've verified; the runout is code merged since; the fall is the incident in code nobody on the team really knows.

Reacts to change

Open a PR or merge to main and RUNOUT reads the diff — automatically, through a GitHub App, or on demand with a click.

Asks sharp questions

Three-option questions about why a decision was made, what trade-off it resolved, and what breaks if an invariant is violated — never "what does this method do."

Targets your blind spots

Miss a topic and about half your next quiz drills it. A comprehension trend shows whether your understanding is keeping pace with your shipping.
