slop-detector

slop-detector is a skill for Claude Code from wpgaurav/claude-code-skills. It costs 96 tokens per session (1,401 once invoked), scanned A, original, MIT.

A review tool that rates writing for common signs of machine-generated, formulaic prose using four levels of severity. It examines the whole piece as well as individual words and repeated writing patterns.

In plain words
What is it for?
Use it to check articles, pages, captions, and other reader-facing copy before publication. It can identify exact process descriptions, repeated rhetorical patterns, broad word-choice signals, and document-level issues.
Why use it?
A simple banned-word list can flag harmless wording or miss writing that sounds artificial for other reasons. This tool helps decide what must be rewritten, what needs review, and what is only a possible concern.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

slop-detector scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/check-assets.py, scripts/scan.py, scripts/test-severity.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Slop Detector

Audit prose for AI slop and report findings by severity. Stop Slop tells a model what not to write; this skill checks what was written and says how bad it is.

A banned-words list fails in both directions. It flags "robust" in a sentence about a nonce implementation, and it passes a caption that says "a fresh capture, not a generic mockup." The severity model below separates the two.

Severity model

slop-detector.json in this folder is the authority. Four tiers:

Severity Meaning What to do
hard_fail Exact, high-confidence production or process narration in reader-facing copy ("captured with Playwright", "Status in this study", "Weak spot: I didn't test") Block publication and rewrite. A low score never rescues a hard fail.
warn_if_repeated Rhetorical scaffolds that can carry one real turn: mirrored "not X, it's Y" contrasts, "No X. No Y. No Z." triads, per-item disclaimers, templated roundup filler Count across the piece. Warn only at the family's repeat threshold.
contextual_review Broad lexical signals: "leverage", "seamless", "here's the thing", academic connectors, empty intensifiers Read the sentence. Quotations, code, proper names, and precise technical terms are not defects. Never auto-replace.
structural_diagnostic Document-level patterns: identical paragraph lengths, a dead table column, the same sentence closing every item, passive-voice density Diagnose the cause. Never add fragments, emotion, or asymmetry to make a metric pass.

Advisory score, counted only after context review: warn_if_repeated +2, confirmed contextual_review +1, structural_diagnostic +3, +2, or +1 by priority.

  • 0 to 5: clean
  • 6 to 15: needs editing
  • 16+: rewrite the affected passages or structure

Truth, source fidelity, and authorial intention sit above this model. An unsupported claim or invented first-person experience blocks publication even when the score is 0.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
