restore-function-signatures

What problem does it solve?

Decompiler output often replaces real function signatures with generic types and placeholder names, making recovered C/C++ code hard to compile and understand.

Core Features & Use Cases

• Function signature restoration: Recover return types, parameter types, parameter names, and calling conventions from degraded decompiler output.
• UB downgrade recovery: Detect and restore parameters dropped by signature-degrading casts (CWE-457 style) to reintroduce the missing arguments.
• Memory-semantics-first validation: Prioritize preserving dereference depth and data-flow paths while improving only the signature surface to reach strict compilation.

Quick Start

Use the restore-function-signatures skill on your decompiled .c file where function signatures look like __int64 sub_401230(__int64 a1, int a2) and ask it to restore return type, parameter types, parameter names, calling convention, and any dropped parameters.
