cargo-crev adds LLM-assisted code reviews — a second wind for supply-chain checks
What happened
It has been reported that cargo-crev, the Rust-focused implementation of the Crev review Web of Trust, now ships with LLM-assisted code review features. The maintainer says this was motivated by the long-running problem that developers simply don’t have the time to manually review every dependency — a noble idea stalled by reality. The emotional beat here is simple: a project that went quiet from exhaustion might be getting its mojo back, thanks to automation.
How it works
In the initial release the built-in flow uses a Claude Code agent to run reviews; it has been reported that support for other agents should be relatively easy to add. The tool exposes commands such as cargo crev ai review-loop --iterations 10 to run a repeat-review loop, and cargo crev ai skill review as the core review skill for custom workflows. Reviews are tagged to indicate LLM involvement, and options to ignore LLM-generated reviews are being kept for skeptics.
Why it matters
It has been reported that new LLMs are increasingly capable of surfacing non-trivial security issues, and Linux kernel and curl developers allegedly say AI-assisted reports are becoming more useful than the flood of low-value noise they once saw. Can AI handle the 90/10 noisy-but-useful scanning that humans won’t? Maybe not a silver bullet, but it could do the tedious heavy lifting — find mismatched crates.io vs git contents, odd build.rs tricks, or obvious malware traces — freeing human reviewers to focus on the subtle, high-impact problems.
In short: cargo-crev’s LLM integration isn’t flashy, but it’s practical. Give it a spin — or, at least, keep an eye on whether AI can finally do the busywork and let maintainers do the craft.
