Building the Automated Gauntlet

Green, yellow, red. The code never reaches a human until the gauntlet speaks.

Real-world application: Engineers who can compose lint + SAST + dependency scan + AI review into a pre-PR pipeline with green/yellow/red lanes demonstrate CI/CD engineering and quality gate design skills that teams using AI at scale need.

Introduction

Building the Automated Gauntlet

Objective

Run the automated gauntlet on 3 demo PRs, observe the green/yellow/red lane classification, and understand how the 70-point quality score and check results determine the lane.

Green, yellow, red. The code never reaches a human until the gauntlet speaks.
