// Data-driven: loads scenarios from knowledge/attack-scenarios.json,

// runs each against the plugin's own hooks via runHook(), reports defense score.
|
|
//
|
|
// CLI: node scanners/attack-simulator.mjs [--category <name>] [--json] [--verbose] [--adaptive]

|

// Categories: secrets, destructive, supply-chain, prompt-injection, pathguard,

// mcp-output, session-trifecta, hybrid, unicode-evasion, bash-evasion,

// hitl-traps, long-horizon
