The Thesis

Most systems marketed as "AI agents" are prompt-chained wrappers around LLM APIs. This benchmark quantifies the architectural difference with empirical evidence by simulating three agent archetypes under controlled conditions and measuring success rate, context retention, cost efficiency, and resilience under stress.

The three archetypes:

Agent Type	Architecture	Planning	Memory	Recovery
Wrapper Agent	Single LLM call	None	Stateless	No retry
Marketing Agent	Basic orchestration	Static	Ephemeral	Limited
Real Agent	Full autonomous system	Hierarchical	Semantic	Multi-strategy

Core Results

Standard benchmark (5 iterations):

Agent Type	Success Rate	Context Retention	Cost per Success
Wrapper Agent	20-27%	11-13%	$0.008-$0.010
Marketing Agent	47-67%	62-63%	$0.090-$0.129
Real Agent	93%	93-94%	$0.031-$0.032

Performance gap: 66-73 percentage points between Real Agent and Wrapper Agent.

Under stress (tool failures + network issues): Real Agents maintain 75% success. Wrapper Agents collapse to 22%. Marketing Agents, which appeared functional in ideal conditions, drop to 25%, revealing that their orchestration layer provides no meaningful resilience.

Network resilience testing: Real Agents achieve a resilience factor of 5.17. Wrapper Agents score 0.59, meaning they perform almost 9x worse under unstable network conditions than the baseline would predict.

The Multi-Agent Finding

Every ensemble pattern tested performed worse than individual Real Agents.

Ensemble Pattern	Success Rate	vs Individual Real Agent
Pipeline	0.0%	-69.0%
Parallel	22.2%	-46.7%
Hierarchical	22.2%	-46.7%
Consensus	22.2%	-46.7%
Specialization	22.2%	-46.7%

0% positive synergy rate across all patterns. Average ensemble advantage: -40%. Coordination overhead adds 0.5-1.5 seconds per task with no performance benefit.
