Use it with IDA Pro to find the refresh function in Windows or Linux CS2 engine files.

It helps recover the function when the normal preprocessor search fails. It records function information such as its address and size for later analysis, while requiring reference values to be checked against the current binary.

find-CLoopTypeClientServer_RefreshNetworkGameState

Q: What is find-CLoopTypeClientServer_RefreshNetworkGameState?

A reverse-engineering procedure for locating the function that refreshes Counter-Strike 2's client/server network state. It starts from a related per-frame update function and follows its direct call in the engine binary.

Token cost

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	$0.00155	$0.01127
Opus 5.5	$0.00062	$0.00451

Security

Grade A, and why

find-CLoopTypeClientServer_RefreshNetworkGameState 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 yesterday.

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.

Find CLoopTypeClientServer_RefreshNetworkGameState (Agent fallback)

Locate CLoopTypeClientServer_RefreshNetworkGameState in CS2 engine2.dll / libengine2.so using IDA Pro MCP tools. This is the Agent fallback for the find-CLoopTypeClientServer_RefreshNetworkGameState preprocessor: it runs only when the preprocessor returned failure, and reproduces its LLM_DECOMPILE step by hand.

The target is a regular (non-virtual) function. The output YAML carries func_sig, func_va, func_rva, func_size.

Realworld Function Reference

Read the platform-relevant reference YAML first. It has the disassembly, the decompiler output, and the annotated call sites. Treat addresses as reference-build values only.

Windows: ida_preprocessor_scripts/references/engine/CLoopTypeClientServer_Update.windows.yaml
Linux: ida_preprocessor_scripts/references/engine/CLoopTypeClientServer_Update.linux.yaml

Background

CLoopTypeClientServer_Update(this, ...) is the per-frame update of the client/server loop type. In the loop-mode switch paths it calls CLoopTypeClientServer_RefreshNetworkGameState(this) with only this as argument (rcx on Windows, rdi on Linux). The callee releases the cached client/server game objects (this+0x130 / this+0x138), re-queries them from g_pNetworkClientService / g_pNetworkServerService, calls AddRef on the new ones and refreshes the this+0x128..0x12A availability flags.

There are two call sites in Update; both call the same function. One follows a g_pEngineServiceMgr/g_pSource2V8System vcall run and a sub_* call, the other sits next to the mov byte ptr [..], 0 that clears a local flag. Both resolve to the same address.

Step 0. Skip if already produced

If CLoopTypeClientServer_RefreshNetworkGameState.<platform>.yaml already exists beside the binary and parses to a non-empty mapping, skip.

Step 1. Decompile the caller

ALWAYS use SKILL /get-func-from-yaml with func_name=CLoopTypeClientServer_Update to obtain its func_va. If it returns an error, STOP and report it.
