What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00135 | $0.01073 |
| Opus 5 | $0.00068 | $0.00536 |
| Sonnet 5 | $0.00027 | $0.00215 |
| Haiku 4.5 | $0.00014 | $0.00107 |
Grade A, and why
find-IVEngineServer2_GetClientSteamID scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Find IVEngineServer2_GetClientSteamID (final-guarantee fallback)
Recover the virtual function IVEngineServer2::GetClientSteamID in CS2 server.dll /
libserver.so using IDA Pro MCP tools. This is the Agent fallback for the
find-IVEngineServer2_GetClientSteamID skill: it runs only when the preprocessor script returned
failure (almost always a transient LLM error, or the predecessor's call structure moved).
Realworld Function References
Read the platform-relevant reference YAMLs before searching in IDA. Treat their addresses as reference-build values only; verify against the current binary.
- Windows baseline:
ida_preprocessor_scripts/references/server/CBasePlayerController_HandleCommand_JoinTeam.windows.yaml - Linux baseline:
ida_preprocessor_scripts/references/server/CBasePlayerController_HandleCommand_JoinTeam.linux.yaml
Step 1. Load and decompile the predecessor
ALWAYS Use SKILL /get-func-from-yaml with
func_name=CBasePlayerController_HandleCommand_JoinTeam to obtain its func_va. If it returns an
error, STOP and report to user (this fallback cannot run without the predecessor).
Decompile it:
mcp__ida-pro-mcp__decompile addr="<CBasePlayerController_HandleCommand_JoinTeam.func_va>"
Step 2. Locate the vtable-slot reference to the target
IVEngineServer2::GetClientSteamID is reached through the global g_engine. Important: in this
predecessor the compiler hoists the slot into a register instead of calling it in place, so the
reference is a mov, not a call. Searching only for call qword ptr [reg+...] will find nothing.
Anchor by the semantic fingerprint, not a fixed offset — load the interface pointer from
g_engine, load its vtable, then fetch the slot:
- Linux:
lea rax, g_engine->mov r12, [rax]->mov rax, [r12]->mov r13, [rax+228h] - Windows:
mov rax, cs:g_engine->mov rcx, [rax]->mov rbx, [rcx+228h]
Reference build vtable offset (verify, do not hardcode): vfunc_offset = 0x228 (552),
vfunc_index = 69 on both platforms. The predecessor contains more than one such fetch; any of them
resolves the same slot.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

find-IVEngineServer2_GetClientSteamID is a skill published in the GitHub repository HLND2T/CS2_VibeSignatures (65 stars, last pushed yesterday), licensed MIT. It adds 135 tokens to every session and 1,073 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
