PR review queue piles up as AI agents ship code 10x faster than humans can review it
AI coding agents create code at a pace human reviewers cannot match. Teams report 30 PRs/day with 6 reviewers and describe feeling like 'the first human to ever see this code'. The review bottleneck is now the single biggest constraint on AI-assisted development velocity. Haystack (launched May 2026, 45 HN points) triages PRs into safe-to-merge, needs-fixes, and needs-human-review buckets, proving the gap. CodeRabbit, Greptile, and Graphite exist but are cloud-only commercial tools; no open-source CLI that runs the triage locally and flags only the PRs that genuinely need a human.
