Fed it a filter-word-heavy throwaway paragraph ('felt,' 'saw,' 'heard' six times across five sentences): it correctly named the issue as its own 'Filter Words' category and produced an original-vs-revised block through the Line Editing Report format -- a bare editing pass caught the same problem unprompted, so the real gain is the structured report and AskUserQuestion accept/reject workflow, not sharper prose sense.

What Crucible Editor does

A structured revision assistant for novel manuscripts that walks a draft through developmental, line, copy, and polish editing passes, using the AskUserQuestion tool for scope and accept/reject decisions at each stage. Triggers on 'edit my novel,' 'revise chapter X,' 'polish my manuscript,' or when a completed draft needs improvement, and is built to consume outputs (chapters, outline, style profile) from the companion Crucible drafting skills in the same repo. All four bundled reference docs and all four bundled scripts resolve correctly.
