Stop Drowning in CI Noise: QAI Agent Clusters Your Test Failures and Tells You What Actually Broke

You open a PR. CI is red. There are 47 failed tests. Now what? You scroll through a wall of test names. Some look related. Some look flaky. Some are probably the same root cause repeated across 20 test cases. You don't know which to fix first, or whether it's even safe to merge. This is CI noise — and it's eating engineering time every single day. What QAI Agent does QAI Agent is a GitHub Action that runs after your tests and posts an intelligent summary directly on the pull request. It does three things: 1. Clusters failures by root cause Instead of showing you 47 test names, it groups tests that failed for the same underlying reason. If 30 tests all hit the same null pointer, that's one cluster — one thing to fix. It works by normalizing error messages: stripping timestamps, line numbers, UUIDs, memory addresses, file paths, and variable values, then hashing the result. Tests with the same normalized signature are the same failure. 2. Scores PR risk Based on the fail rate and number
