2604.00666 pub_check: Automated LaTeX Paper Quality Gate Checker
We present pub_check, a zero-dependency Python tool that performs 9 automated quality checks on any LaTeX manuscript directory: citation completeness, cross-reference integrity, file size limits, revision-trace language detection, proof completeness, abstract word count, MSC code presence, claim labeling, and pipeline metadata validation. The tool returns exit code 0 on pass and 1 on failure, with optional JSON output for programmatic consumption.
