CS2_VibeSignatures: Skill for Claude Code

Find CCSGameRules__sm_mapGcBanInformation

Locate CCSGameRules__sm_mapGcBanInformation (global variable) in CS2 server.dll or libserver.so using IDA Pro MCP tools.

Prerequisites

• CCSPlayerController_ResourceDataThink must be identified first (Linux method depends on it)
• Use SKILL /get-func-from-yaml to load CCSPlayerController_ResourceDataThink if its YAML already exists

Method

Windows: String-based approach

1. Search for the debug string

mcp__ida-pro-mcp__find_regex pattern="Notification about user penalty: %u/%u"

2. Get cross-references to the string

mcp__ida-pro-mcp__xrefs_to addrs="<string_addr>"

3. Decompile the referencing function

mcp__ida-pro-mcp__decompile addr="<function_addr>"

4. Identify the global variable

Look for the pattern after the DevMsg("Notification about user penalty: %u/%u (%u sec)\n", ...) call:

sub_XXXXXXXX(&unk_YYYYYYYY, &v10, &v12);

Where unk_YYYYYYYY (the second argument, offset by +8 from the base) is CCSGameRules__sm_mapGcBanInformation. The base address is unk_YYYYYYYY - 8.

More specifically, look for:

v12 = &unk_181E4C960;       // unk_181E4C960 is CCSGameRules__sm_mapGcBanInformation - 8
LOBYTE(v13) = 1;
v14 = &v17;
v18 = 0LL;
v19 = 0LL;
sub_XXXXXXXX(&unk_181E4C968, &v10, &v12);  // unk_181E4C968 is CCSGameRules__sm_mapGcBanInformation

The global variable to rename is the one passed as the first argument to the map lookup function (e.g., unk_181E4C968).

Linux: Decompilation-based approach

1. Load CCSPlayerController_ResourceDataThink address

Use SKILL /get-func-from-yaml to get the address, or decompile it directly:

mcp__ida-pro-mcp__decompile addr="<CCSPlayerController_ResourceDataThink_addr>"

2. Decompile the sub-function called inside ResourceDataThink

The wrapper function calls a sub-function as its second operation:

__int64 __fastcall CCSPlayerController_ResourceDataThink(__int64 a1, ...)
{
  ++*(_DWORD *)(a1 + 3084);
  sub_YYYYYY(a1, ...);    // <--- decompile this function
  ...
}
