An article titled "100 Consecutive Slop Expressions" (by todesking, 2026-10-12), which collected unnatural expressions appearing in Japanese written by AI, became a hot topic. After reading it, the question arises: "If I make this a prohibition list and hand it over, will the AI smelliness disappear?" Therefore, Claude Code (Sonnet) was used to write technical articles, practical texts, slides, and novels for comparison.

Following the article "100 Consecutive Slop Expressions" (by todesking, 2026-10-12), which collected unnatural expressions in Japanese written by AI, a verification was conducted to see if AI smelliness could be eliminated using a prohibition list. The verification used Claude Code (Sonnet) and targeted four patterns: technical articles, practical texts, slides, and novels.

The comparison methods were: 1. Do nothing, 2. Hand over an example article as a prohibition list, 3. Hand over only type definitions, and 4. After writing, put through refinement skills (yomiyasu). In the verification, 57 written pieces and 38 refined pieces were counted.
