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 | $0.00133 | $0.01032 |
| Opus 5 | $0.00067 | $0.00516 |
| Sonnet 5 | $0.00027 | $0.00206 |
| Haiku 4.5 | $0.00013 | $0.00103 |
Grade A, and why
find-INetworkServerService_IsServerRunning 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 11d 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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Find INetworkServerService_IsServerRunning (final-guarantee fallback)
Recover the virtual function INetworkServerService::IsServerRunning in CS2 engine2.dll /
libengine2.so using IDA Pro MCP tools. This is the Agent fallback for the
find-INetworkServerService_IsServerRunning 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. They contain the annotated virtual
call site (; 0x0E8/0x0F0 = ... = INetworkServerService_IsServerRunning). Treat their addresses as
reference-build values only; verify against the current binary.
- Windows baseline:
ida_preprocessor_scripts/references/engine/CNetworkGameClientBase__ProcessNetworking.windows.yaml - Linux baseline:
ida_preprocessor_scripts/references/engine/CNetworkGameClientBase__ProcessNetworking.linux.yaml
Step 1. Load and decompile the predecessor
ALWAYS Use SKILL /get-func-from-yaml with func_name=CNetworkGameClientBase__ProcessNetworking 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="<CNetworkGameClientBase__ProcessNetworking.func_va>"
Step 2. Locate the virtual call to the target
INetworkServerService::IsServerRunning(this) is an indirect virtual call on the global
g_pNetworkServerService. Anchor by its semantic fingerprint, not a fixed offset:
- It is the (single)
call qword ptr [reg + <off>]wherereg = *g_pNetworkServerService(load the vtable from the global, then call through it). - It returns a boolean (
al) that is stored/tested to gate the per-tick client networking processing.
Reference build vtable offsets (verify, do not hardcode):
- Windows:
call qword ptr [rax+0E8h]->vfunc_offset = 0xE8(232),vfunc_index = 29 - Linux:
call qword ptr [rax+0F0h]->vfunc_offset = 0xF0(240),vfunc_index = 30
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-INetworkServerService_IsServerRunning is a skill published in the GitHub repository HLND2T/CS2_VibeSignatures (65 stars, last pushed yesterday), licensed MIT. It adds 133 tokens to every session and 1,032 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 2026-08-30.
