Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00048 | $0.02469 |
| Opus 5.5 | $0.00019 | $0.00988 |
| Sonnet 5.5 | $0.00010 | $0.00494 |
| Haiku 4.5 | $0.00005 | $0.00247 |
Grade A, and why
ghostwriter 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 335 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Ghostwriter Skill
Purpose
This skill transforms source material - transcripts, notes, research, interviews - into authentic, human-written content that reads naturally without obvious AI tells. It extends the anti-ai-writing skill by adding voice adaptation and source material conversion techniques.
Core Philosophy: The best ghostwriting is invisible. Readers should feel like they're reading a real person's thoughts, not a filtered or processed version of source material.
This skill assumes you've read the anti-ai-writing skill. It builds on those fundamentals with additional techniques for voice adaptation and source material conversion.
When to Use This Skill
Use the Ghostwriter skill when:
- Converting transcripts or interviews into polished articles or newsletters
- Refining notes into publishable content
- Converting source material into different voices or styles
- Building content that maintains a distinctive, personal voice
- Adapting writing to match a specific author's style
Use in conjunction with:
- anti-ai-writing skill for core humanization patterns
- Voice style profiles for adapting to specific voices
- Source material that needs authentic conversion
- brand-identity-wizard profile for brand voice consistency
The 8 Human Desires Framework
Great writing taps into core human desires. Choose 1-2 per piece:
1. Safety of Tribe
Belonging, community, fitting in
- "The hidden skills that separate successful people from struggling ones"
- Use when: Readers need to feel part of something larger
2. Survival & Success
Progress, achievement, security
- "The greatest threat to your potential is getting tied down too early"
- Key phrases: "breakthrough," "advancement," "finally," "unlocked"
3. Life Enjoyment
Pleasure, experiences, freedom
- "Why most people miss the best parts of their work"
- Key phrases: "savor," "freedom," "experience," "joy"
4. Social Acceptance
Status, respect, recognition
- "What successful people know that average people don't"
- Key phrases: "elite," "leaders know," "insiders understand"
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.

ghostwriter is a skill published in the GitHub repository cdeistopened/skill-stack (30 stars, last pushed 3mo ago), licensed MIT.
