anti-ai-writing

anti-ai-writing is a skill for Claude Code, Codex from cdeistopened/skill-stack. It costs 61 tokens per session (3,197 once invoked), scanned A, original, MIT.

A writing guide for making AI-assisted drafts sound more like natural human writing. It identifies common signs of machine-generated prose and explains how to revise them.

In plain words
What is it for?
Use it to review AI-generated drafts, edit prose for authenticity, write content that should not appear AI-assisted, and check writing before publication.
Why use it?
It helps remove stiff, repetitive, overly polished, or formulaic language before content is published. This makes the writing feel more personal and readable.

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

anti-ai-writing 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 5d 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.

Anti-AI Writing Engine

Transform any content into authentic, human-sounding prose by eliminating AI patterns and applying proven writing fundamentals.

Purpose

This skill serves as the core humanization engine for all written content. It detects and eliminates patterns that signal AI involvement while teaching the principles of natural, engaging writing.

Core Philosophy: The best writing is invisible. Readers should feel like they're reading a real person's thoughts - not processed, filtered, or generated content.

When to Use This Skill

  • Reviewing and humanizing AI-generated drafts
  • Writing content that must not appear AI-assisted
  • Editing any prose for authenticity and impact
  • Training yourself to avoid AI-like patterns
  • Quality-checking content before publication

Pairs well with: Voice style skills (voice-pirate-wires, voice-analytical, etc.) for writing in a specific author's style.


Universal Writing Fundamentals

Master these principles first, then layer on specific style choices.

1. Energy Transfer

The best writing is a transfer of energy from writer to reader.

  • Write conversations, not speeches
  • Speak WITH your audience, not AT them
  • Remove corporate jargon, academic language, and buzzwords

Example:

  • ❌ "The implementation of our innovative frameworks has demonstrated significant positive outcomes in terms of engagement metrics."
  • ✅ "Our new approach works. People are paying attention."

The second version transfers energy. Readers feel conviction, not formality.

2. Conciseness is King

Every word must earn its place.

Process:

  1. Write your first draft freely
  2. Read it aloud
  3. Delete anything that:
    • Repeats an idea already stated
    • Softens your main point
    • Sounds formal instead of conversational
    • Takes more words than necessary

Example:

  • ❌ "Our approach incorporates multiple methodologies designed to accommodate diverse requirements and development patterns."
  • ✅ "We adapt to how you work."

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.
