🔧 Usage Examples

Basic Memory Analysis

; Analyze memory region for patterns
(analyze-memory 0x401000 1024 "Look for string patterns and API calls")

; Get AI insights on assembly code
(disasm-ai 0x401000 32 "Explain what this function does")

; Search for vulnerabilities
(find-vulns 0x400000 0x500000 "Check for buffer overflows")

AI-Powered Debugging

; Ask natural language questions
(ask "What does this function at 0x401234 do?")
(ask "Are there any security issues in this code?")
(ask "Explain the calling convention used here")

; Pattern-based analysis
(find-patterns "encryption" 0x400000 0x500000)
