Risk-scored PR triage layer that decides which AI-generated changes a human actually needs to look at

dev tool real project •• multiple requests

Teams shipping AI-generated code say review, not coding, is now the bottleneck, and today's AI reviewers just post more comments on every PR instead of deciding what needs human eyes at all. The opportunity is a layer that scores each PR's risk (blast radius, test coverage, path sensitivity) and auto-merges the trivial low-risk majority while escalating only genuinely risky changes to scarce human reviewers.

builder note

Don't build another AI reviewer; the gap is the policy engine on top, a risk score teams trust enough to auto-merge the boring 70%, because trust is the only thing that actually removes review load.

The 2026 AI-review tools all add review signal to every PR; none act as a triage layer that decides which changes can bypass human review, which is precisely the bottleneck teams describe.

CodeRabbit Diff-based AI review that comments on every PR, adding to the reading load rather than triaging which PRs can skip a human entirely.

Greptile Deep codebase-graph bug catching, but it still produces review signal to read and has historically been noisy (many false positives); it does not route PRs by risk.

Graphite Stacked-diff workflow with AI review woven in; optimizes PR size, not risk-based allocation of human attention, and has no auto-approve-low-risk gate.
