Descriptions:
AI agent context files are what keep a long agent run on track once your opening prompt goes stale. Here is how OpenAI, Anthropic, and Arize actually structure them, and the four files you can copy.

What’s really happening inside a six hour agent run?
The common story is that a bigger context window solves this, but the real question is which decision the agent treats as current.
In this video, I share the inside scoop on progressive context shaping:
– Why one giant instruction file becomes a graveyard of stale rules
– How to change an agent’s direction without restarting the project
– What four kinds of context you should keep separate
– Where OpenAI, Anthropic, and Arize put the current plan
More capable agents extend the reach of your judgment, and they extend the reach of an outdated judgment exactly as far.
