+- The `/ai-slop:audit` description names commit messages, PR bodies, interface copy and generic headlines beside markdown, and sends code-comment requests to `/code-tidying:audit-comment-residue`. Measured before and after on the frozen probes and a blind held-out set on Opus 5.5 and Sonnet 5.5, every run VALID: no lost trigger, and held-out triggering rose from 58% to 83% on Opus and from 57% to 70% on Sonnet.

-description: "Audit markdown prose for AI-writing tells (slop): em dashes (zero-tolerance by default), emoji formatting, AI vocabulary, negative parallelisms, chatbot phrases, filler, stacked hedging, citation artifacts, model-era phrases ('that's the unlock', 'the part most people skip'), and the rest of the catalog (distilled from Wikipedia's Signs of AI writing plus an evolving model-era inventory), plus a judgment rubric for superficial analysis, vague attribution, promotional tone, metaphor jargon ('load-bearing', 'seam'), figures standing in for facts, over-compressed text, and mechanism-free claims. Use when: 'check for AI slop', 'de-slop this doc', 'unslop this', 'find AI tells', 'does this read AI-written', 'remove em dashes', or before publishing agent-written prose. Read-only by default; 'fix' as an explicit argument applies rewrites behind a semantic-diff guard and may be chained ('detect and rewrite'). Empty target audits the repo's tracked markdown, high-impact and high-velocity files first."
