The Death of Prompt Engineering

In 2023, everyone was a "Prompt Engineer". We spent hours tweaking words: "Think step by step", "Act as an expert", "Take a deep breath".

It felt like casting magic spells.

The Problem with Spells

Spells are fragile. A model update breaks them. A slightly different input breaks them. They are not engineering.

Enter Cognitive Architectures

Instead of one giant prompt, we now build Architectures.

• Decomposition: Break the task into 5 sub-steps.
• Routing: Send each step to the best model.
• Reflection: Have a second agent critique the first agent's work.
• Memory: Retrieve relevant context before generating.

The Data

We ran a benchmark comparing "Super Prompting" vs "Simple Chain of Thought Architecture".

• Prompting: 68% accuracy on complex reasoning.
• Architecture: 92% accuracy.

Stop casting spells. Start building systems.
