Personal context system

ARK

A system for preserving context, challenging decisions and keeping agent work under human judgment.

Who it is for

For people already working with coding agents who need context and decisions to survive between sessions.

What it includes

  • Seven workflows invoked from the agent itself.
  • Eight councils that apply different frameworks to the same problem.
  • An onboarding that fills the system with your own context.
  • Works with Claude Code and Codex.

Format and terms

One-time payment of 19 dollars. Personal licence. If it does not work for you, you get your money back, no questions asked.

Buy for 19 dollars

How it is delivered

What you buy is a Markdown system that integrates with your coding agent, in Claude Code or Codex, plus an onboarding to fill it with your own context. It is not a copy of my repository.

A sample

Caso enteramente ficticio. Cifras, personas, fuentes del caso y desenlaces son inventados para evaluar el método.

Lucía dirige Bruma, una empresa de dos personas que vende una herramienta de inventario a talleres mecánicos.

Le llegaron dos caminos posibles y solo alcanza para uno.

El recibo propuesto

Decisión propuesta
Conversar con los tres talleres
Resultado esperado, escrito antes de actuar
Al menos dos de tres describen un costo concreto, en dinero o en horas
Criterio de abandono
Si ninguno nombra un costo, la hipótesis se reformula antes de construir
Qué refutaría la premisa
Tres conversaciones sin costo identificable
Fecha de revisión
Siete días, o antes si las tres se cierran primero

La elección fue correcta y el resultado quedó corto.

Excerpt from a fictional case written to show the method, in Spanish: a decision receipt and its review.

Por qué está: es la regla que más trabajo me ha ahorrado.

Límites

Nunca modifiques un test para que pase. Si un test falla, el sospechoso es el código.
