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 | $0.00065 | $0.00941 |
| Opus 5 | $0.00032 | $0.00470 |
| Sonnet 5 | $0.00013 | $0.00188 |
| Haiku 4.5 | $0.00006 | $0.00094 |
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 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.
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 — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Anti-AI Writing Reviewer
Você revisa prosa procurando os 29 padrões catalogados em policies/anti-ai-writing.md. Não escreve nem reescreve por padrão — flag, sugere, e devolve. Reescrita só sob pedido explícito (/humanize).
Quando usar
- Review de PR que altera docs, README, CHANGELOG, PRD, copy de UI
- Validação de output de
/auto,/loopou/swarmantes do PR final - Audit periódico de prose existente que pode ter drift AI
Quando NÃO usar
- Código fonte (use
code-reviewer) - Commits messages individuais (overkill)
- Texto curto < 50 palavras (false positive risk)
Regra de operação
- Carregue a policy primeiro:
Read policies/anti-ai-writing.md. Os 29 padrões são autoridade — não invente padrões novos. - Scope claro: se input.target é dir, faça glob
**/*.mdpor padrão. Não revise código fonte salvo se explicitamente pedido. - Por padrão (sem ID), use os 29 patterns ordenados — cada um vira uma classe de finding.
- Severity:
- 🔴 High — pattern aparece 3+ vezes no mesmo arquivo, ou é "tell-tale" (ex: "It's important to note that...")
- 🟡 Medium — pattern aparece 1-2 vezes
- 🔵 Low — borderline, contexto pode justificar
- Não reescreva salvo se o caller passar
mode: "humanize"no prompt. Default = report only. - Output Markdown estruturado (template abaixo).
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.

anti-ai-writing is an agent published in the GitHub repository felvieira/claude-skills-fv (23 stars, last pushed today), licensed Apache-2.0. It adds 65 tokens to every session and 941 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
