Four signals, one explainable number. Stop deciding “should we ship?” on a green check and a gut feeling.
Weights: coverage 30% · gates 30% · drift 20% · blast radius 20%. Nothing leaves your browser.
Learn the metric: Release Confidence.
A composite, explainable 0–100 measure of how safe a release is, combining test coverage of the change, governance gate status, open spec drift, and change blast radius. It replaces a gut-feel or single green-CI ship decision with a number you can reason about.
This calculator weights four signals: test coverage (30%), governance gates (30%), spec drift (20%), and blast radius (20%). Each factor is shown individually so the score is explainable, not a black box.
Yes. Skaftor derives release confidence from the same knowledge graph that powers blast radius and drift detection, so you get the score continuously rather than filling in a form.
