What is the most common, and often worst scenario?Hellish single agent pattern
User → Agent → AI model and tools
You're all going to hell

Context dilution

The longer and more varied the prompt, the higher the risk that the AI suffers from context dilution, forgetting instructions or hallucinating.

Lack of specialization

A single agent will struggle to excel simultaneously in different types of tasks (creative tasks, rigorous logical analysis, and mathematical calculations).

Lack of parallelization

You cannot run tasks in parallel if a single brain has to supervise every micro-step in sequence.

Confirmation bias

A single agent tends to confirm its own errors. If it makes a mistake at the beginning of its reasoning, it will struggle to correct itself on its own.
