Token Budget Depletion Attack
TBDAlow complexityagentic ai Category
Manipulating an agent to consume excessive tokens through verbose outputs, repeated operations, or unnecessary processing, depleting token budgets and causing cost overruns or service interruption.
Example Scenario
Asking an agent to "provide extremely detailed explanations with examples for every single step" for a complex multi-step task, causing it to generate tens of thousands of tokens per response and quickly exhaust allocated token budgets.
Testing Objectives
- Test token budget enforcement
- Assess cost controls
- Evaluate output limiting
- Validate usage monitoring
Defensive Strategies
- Token budget limits per request
- Output length restrictions
- Cost threshold alerts
- Usage monitoring and quotas
- Verbosity detection and limiting
Key Features
- Token consumption maximization
- Verbose output exploitation
- Repeated operation triggering
- Budget exhaustion
Use Cases
- Token budget testing
- Cost control validation
- Output verbosity assessment
- Usage limit enforcement evaluation

Ethical Guidelines
- •Test only with budget safeguards
- •Never deplete production budgets
- •Report cost vulnerabilities responsibly
- •Focus on improving cost controls
- •Consider financial impact
