slop-sense

Slop Sense

A three-skill plugin that detects, scores, and explains AI-generated text. Paste text in, get back an analysis of which AI patterns it contains, a rewritten version that sounds human, or a deep-dive on a specific pattern you want to understand.

The three skills

All three share the same 36-pattern catalog and the same scoring scripts. They differ in workflow and output.

What slop-sense does

1. Runs the slop-detector algorithmic scorer via npx (no install needed, just Node.js). Returns a 0-100 SLOP score with specific word hits, trigram matches, and contrast patterns found.
2. Runs a bundled rhythm checker (rhythm.py, pure Python, no dependencies) that measures what the SLOP scorer can't: sentence-length variation (burstiness), contraction ratio, aphoristic paragraph closers, and anaphora. These are the structural tells perplexity detectors like GPTZero score, and a text can rate "very human" on SLOP while failing badly here.
3. Scans for 36 qualitative AI writing patterns: significance inflation, promotional language, AI vocabulary, copula avoidance, em dash overuse, sycophantic tone, invented concept labels, rhetorical Q&A, false vulnerability, uniform sentence rhythm (low burstiness), and more.
4. Rewrites the text with a two-pass process: draft, then an anti-AI audit that catches what the first pass missed.
5. ai;dr mode: extracts the probable prompt that generated a piece of AI text, with an inflation ratio showing how many words the AI used to say something simple.

Both scripts are optional. The SLOP scorer needs Node.js; the rhythm checker needs only Python 3. Without either, the skill still does the full qualitative analysis and rewrite.

Accepts pasted text, URLs (fetches and analyzes the page), or file paths.

What slop-check does

A read-only verdict skill for when you want a score but plan to fix the text yourself (or run it in CI). Same input handling, same 36-pattern scan, same scoring scripts (lexical + rhythm). Output is a compact table of patterns found with one-line evidence per pattern, plus the verdict band. No rewrite, no audit, no edits to your text.

Triggers on requests like "score this," "rate this text," "how AI is this," "verdict only," "don't rewrite, just check."

What slop-explain does

A teaching skill. Ask "explain pattern 17" or "why is the rule of three a tell" and get a deep-dive on that single pattern: why LLMs produce it, why it reads as AI to a reader, two or three example rewrites, and a checklist for spotting the pattern in your own writing. Pairs naturally with slop-check — check flags pattern #17, explain teaches you why it matters.

Triggers on requests like "explain pattern N," "why is X a tell," "teach me about em dash overuse."

Quickstart

Install the skill with one command. It works for 50+ coding agents:

npx skills@latest add CyranoB/slop-sense

The installer detects your agents, asks which to install for, and places the skill in the right location.

Common variations:

npx skills@latest add CyranoB/slop-sense --list
npx skills@latest add CyranoB/slop-sense -a claude-code -y
npx skills@latest add CyranoB/slop-sense -a claude-code -g

Install For Your Coding Tool

Install as a skill/plugin when your agent supports them. The Quickstart command above is the cross-agent path; per-agent details follow for anyone who wants the specifics.
