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

AI Text Humanizer 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 10d 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.

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.

AI Text Humanizer Guidelines

This skill provides techniques for modifying AI-generated text to make it sound natural, engaging, and genuinely human. AI often defaults to recognizable patterns and vocabulary that feel robotic or overly academic.

1. Avoid AI Tropes and Clichés

Language models tend to overuse certain dramatic or transitional words. Actively identify and replace them.

Words to Avoid (The "AI Blacklist"):

  • Delve, dive into
  • Tapestry, rich tapestry
  • Testament to
  • Landscape (e.g., "the digital landscape")
  • Paradigm shift
  • Unleash
  • Embark on a journey
  • "It is important to note that..."
  • "In conclusion..."

Strategy: Rewrite the sentence to state the fact directly without the metaphorical fluff.

2. Write in Active Voice

Passive voice makes writing feel distant, formal, and confusing. Active voice is direct and energetic.

  • Passive (AI default): The new feature was designed by our team to ensure user satisfaction is maximized.
  • Active (Human): Our team designed the new feature to maximize user satisfaction.
  • Rule: Subject + Verb + Object.

3. Vary Sentence Length and Structure

AI text often has a monotonous rhythm because it generates sentences of similar lengths. Human writing breathes; it has rhythm.

  • Use short, punchy sentences for emphasis.
  • Use longer, complex sentences to explain nuanced ideas.
  • Example Rhythm: This is a short sentence. Here is another one. Then, just when you expect a third short sentence, you encounter a longer, more elaborate structure that connects multiple ideas together seamlessly. It feels natural. It feels alive.

4. Adopt a Conversational Tone

Write as if you are explaining a concept to a smart colleague over coffee.

  • Use Contractions: Use don't, can't, it's, you're instead of do not, cannot, it is, you are.
  • Ask Rhetorical Questions: Engage the reader occasionally (e.g., Sound familiar?).
  • Embrace Imperfections: Minor conversational transitions (like starting a sentence with 'And' or 'But') are perfectly fine and often preferred.

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.
