name	struct-info
description	Get class/struct layout info including members, offsets, parents, and inheritance chain. Also look up which field is at a specific offset. Use when debugging struct alignment or verifying class layouts.

Struct Info Skill

Query the struct database for class/struct layout information.

Arguments

$ARGUMENTS

Steps

1. Parse the arguments. $0 is a class name. Optional $1 is an offset to look up a specific field.

2. If an offset is given, look up the field at that offset:

   python3 tools/struct_db.py lookup $0 $1
   

3. Otherwise, show full class info:

   python3 tools/struct_db.py info $0
   

4. Present the results showing:

   • File path where the class is defined
   • Parent classes and inheritance chain
   • Member table with offsets, types, and names

Tips

• Offsets can be hex (0x48) or decimal (72)
• If the struct DB is missing, rebuild it: python3 tools/struct_db.py build src/
• Use python3 tools/struct_db.py list --pattern '*Rnd*' to search for classes by name pattern
• Use /dc3-pair to find the DC3 source as a cross-reference (same MSVC compiler, same flags — best oracle for engine classes)
• Compare with /ghidra-struct to cross-check against Ghidra's analysis of orig/45410914/default.xex
