Table of words LLM generated, Binary Searched on the output going forward and local skill/CLAUDE.md line with instruction to conform. The comparison then is pretty fast due to the word limitation rules. Also standardized PR format so a bunch of what a dev would usually communicate is just a series of checkboxes and a place for adding an optional link for "additional discussion" on slack as the escape hatch for people who like to waffle.

Binary Searched against a table of words. It's rough at first, but once you add contextual exceptions the false positives calm down. Also the CLAUDE.md file has an instruction to conform before even submitting the PR and there's a skill too for it to self iterate.
