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 B, and why

writing-quality scanned grade B with 2 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 12d ago.

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.

Downloads and executes remote codemediumSupply chain

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

curl -s "https://en.wikipedia.org/w/api.php?action=parse&page=Wikipedia:Signs_of_AI_writing&prop=wikitext&format=json" | python3 -c "

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 605 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Writing Quality

Unified writing quality audit and fix. Combines AI slop detection, evidence-based craft rules, reading level enforcement, and grammar credibility into one skill with one checklist and one scoring system.

What this covers: Everything about writing quality that isn't author-specific voice. What this doesn't cover: Voice alignment — that's voice-editor with VOICE.md.

Workflow:

[Draft] -> writing-quality -> voice-editor -> [Final]
            |                    |
      Fix quality issues    Match author voice

The 30-Second Test

The Horoscope Test:

"Could anyone have written this, for anyone?"

If yes, it's slop. Like a horoscope — technically applicable to everyone, resonant with no one.

What fails:

  • Vague claims without specific examples
  • Advice that applies universally without context
  • Content missing the author's distinct perspective
  • Writing that could have any byline

What passes:

  • Specific tools, dates, outcomes mentioned
  • Personal observations grounded in experience
  • Opinions that not everyone would agree with
  • Details only this author would know

Part 1: Slop Detection

Tier 1: Almost Always AI (Remove Immediately)

These phrases are so strongly associated with AI that their presence alone suggests unedited output.

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.
