meat

meat is an open-source command-line tool from Bold Software, Inc. that condenses a code diff into a shorter "reading diff" for human review. It is aimed at reviewing agent-written code in critical systems, where reviewers need to focus on concepts rather than style details.

What It Is

meat is a code review aid. According to the README, models are now good enough that reviewers no longer need to check style, nil-checks, or imports, and should instead review concepts, algorithm choices, and architecture. meat uses a model to reduce a diff to the important parts and shows only that content.

How It Works

Install it with go install meat.dev/cmd/meat@latest. Running meat reviews the latest commit, and it accepts git-style parameters to choose which commits to review. Processing a commit takes a while, so the README suggests having an agent build meat into your devtools so commits are pre-processed.

Very large diffs are split at file and hunk boundaries and abridged chunk by chunk, up to a few MB. The chunks are merged into a single reading diff, which takes proportionally longer for huge commits.
