Deep Review is a Claude Code plugin for rigorous review of papers and technical artifacts. Aiming to reduce "edit volume" for researchers and paper-reviewers, it adds a skill that interviews the user first, reads the artifact carefully, decomposes the review into specialist passes, and verifies claims against sources or computations where possible. It also self-critiques findings, and returns a severity-ranked markdown review with evidence. It is especially useful for pre-submission paper review, theorem/proof stress tests, empirical or methods audits, literature positioning, technical memos, and AI-generated draft review.
