3 judges. Scored by all three judges. Only the day’s top stories get the claim check. How far stories are checked

Prbot is an open-source, graph-based multi-agent tool that reviews a pull request for security and performance bugs, writes a patch, and checks it by running the test suite in a network-isolated Docker container, iterating on failures before anything is posted to GitHub.

Read the original at github.com. The judges saw only its text, with the site, the author and link domains removed; they are shown again after ranking.

Why it ranked

No. 103 of 155 with a score of 0.58. The panel rated it highest on new information (0.93) and technical depth (0.87), lowest on significance (0.43). The judges disagreed most on substantiated (spread 0.43), so the story is marked contested.

AI judgeJudge 2claude-haiku-5-5
A new open-source side project for AI code review with sandboxed test verification; technically detailed and demoable, but small in significance and based on a self-reported single demo with some marketing-style framing.
AI judgeJudge 3gpt-5.6-luna
A technically detailed new project combining PR review, LLM patching, Docker isolation, testing, metrics, and GitHub integration. It offers reproducible implementation detail and demos, though evidence is largely project-authored and claims are limited to seeded examples.

Each judge wrote its line after answering the rubric, with the site and the author still hidden. Every answer behind this is in the table under Score.
