## Activation Triggers

### Natural Language Patterns

The skill activates when agents recognize these intents:

```yaml
triggers:
  - pattern: "audit|check|validate|assess.*transaction"
    capability: transaction_analysis
    example: "audit this transaction for safety"
  
  - pattern: "validate|check.*function|call"
    capability: function_validation
    example: "validate this smart contract function call"
  
  - pattern: "optimize.*gas|reduce.*cost|batch.*transaction"
    capability: gas_optimization
    example: "optimize my transactions for gas efficiency"
  
  - pattern: "risk|assess|score.*contract|interaction"
    capability: risk_scoring
    example: "assess the risk of this contract interaction"
  
  - pattern: "monitor|track|watch.*contract|interaction"
    capability: contract_tracking
    example: "monitor interactions with this smart contract"
```
