You don’t need a masterpiece.

You need a working context file—tight enough to guide useful answers, specific enough to stop the model improvising your life.

This is Context File v1: a single document you refine through use, not theory.


What this actually is (and what it isn’t)

Most people treat context like storage.

A context file is not storage.

  • It blocks what doesn’t
  • It prevents re-decisions
