Use it to identify the function's machine-code address, signature, and virtual-table slot, then write those results to YAML for later tooling.

It provides another way to locate the function when saved signatures or text references stop working after a new game build changes the compiled code.

find-CNetworkMessages_UnserializeMessageInternal

Q: What is find-CNetworkMessages_UnserializeMessageInternal?

A fallback reverse-engineering procedure for finding a specific Counter-Strike 2 networking function in compiled Windows or Linux game files with IDA Pro, a tool for inspecting compiled programs.

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	$0.00141	$0.03376
Opus 5.5	$0.00056	$0.01350
Sonnet 5.5	$0.00028	$0.00675

Security

Grade A, and why

find-CNetworkMessages_UnserializeMessageInternal 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 1mo 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 — 242 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Find CNetworkMessages_UnserializeMessageInternal (final-guarantee fallback)

Recover CNetworkMessages::UnserializeMessageInternal in CS2 networksystem.dll / libnetworksystem.so using IDA Pro MCP tools.

This is the Agent fallback for the find-CNetworkMessages_UnserializeMessageInternal skill: it runs only when the preprocessor returned failure. The preprocessor tries to reuse the previous build's func_sig and then falls back to two xref-string anchors; on a new build any of those can miss:

the stored func_sig breaks when the prologue is rewritten;
the xref-string fallback breaks when "size_exceeded_max" or "netmessage" lose their direct string xref — these are passed to __MakeGlobalSymbolCaseSensitive, a bare call whose string argument is frequently shared or folded so the XrefsTo lookup returns an empty set (this is exactly how it failed on 14189: empty candidate set for string xref: size_exceeded_max).

Your job is to locate the function by semantic anchors that survive those changes, then emit the YAML.

Realworld Function References

Read the platform-relevant real-world YAMLs before searching in IDA. CNetworkMessages::UnserializeMessageInternal has no dedicated reference YAML, so use the neighbouring CNetworkMessages finders and the ground-truth outputs for context and for the vtable cross-check. Treat addresses, offsets and sizes as reference-build values only; verify every result against the current binary.
