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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00093 | $0.04550 |
| Opus 5 | $0.00046 | $0.02275 |
| Sonnet 5 | $0.00019 | $0.00910 |
| Haiku 4.5 | $0.00009 | $0.00455 |
Grade A, and why
escribir-variantes-de-copy 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 13d 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 — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Escribir variantes de copy
Un skill para cada necesidad de variantes de copy. El parámetro job define la forma, las reglas de fuente y el formato de salida. Regla compartida en todas las tareas: cada variante se basa en una cita real de un cliente o una afirmación del documento de posicionamiento, nada de lenguaje de marketero, nada inventado.
Parámetro: job
headlines- 10 pares de titular + subtítulo para una página indicada, cada uno citando una frase textual de un cliente, con los 3 mejores marcados para probar primero. Salida:headline-variants/{page-slug}-{YYYY-MM-DD}.md.ctas- 5 a 7 variantes de copy para el botón de llamada a la acción, cada una emparejada con la objeción que responde y el resultado que implica. Salida:cta-variants/{page-slug}-{YYYY-MM-DD}.md.ad-copy- 10 titulares + 5 descripciones + 3 conceptos creativos para una campaña y plataforma indicadas, respetando los límites de caracteres de cada plataforma, cada uno basado en una cita fuente. Salida:ad-copy/{campaign-slug}.md.edit- una pasada de ajuste en cinco barridos sobre un copy existente (claridad, voz, especificidad, extensión, CTAs) con antes/después/por qué en cada línea cambiada. Salida:copy-edits/{page-slug}-{YYYY-MM-DD}.md.
El usuario nombra la tarea en lenguaje natural ("10 titulares para mi página de inicio", "mejor CTA para el registro", "copy de anuncios para el lanzamiento de Q2", "ajusta mi página de about") -> infiero. Si es ambiguo -> hago UNA pregunta nombrando las cuatro tareas.
Cuándo usarlo
headlines:
- "10 variantes de titular para mi página de inicio"
- "Ganchos alternativos para el hero de la landing page de {campaign}"
- "Opciones de titular para la página de precios"
- Suele seguir a
write-my-page-copyoaudit-a-surface(surface=landing-page) cuando el titular queda marcado como el arreglo a hacer.
ctas:
- "Mejor CTA para el botón de registro"
- "Variantes de CTA para la página de precios"
- "¿Qué debería decir el botón de demo?"
- Suele seguir a
write-copy-variants(job=headlines) owrite-copy-variants(job=edit) cuando el CTA queda marcado como débil.
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.
