What is find-CNetChan_SendMessages-inlined?

A reverse-engineering procedure for finding the Counter-Strike 2 function CNetChan::SendMessages in a compiled program. It uses IDA Pro to distinguish the target function from a similar caller when the normal automated search cannot decide between them.

Use it to locate SendMessages in CS2's Windows or Linux networking library and record its address, size, signature, and virtual-table slot.

It helps recover the function after compiler inlining or code changes make fixed signatures and string references unreliable.

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	$0.00146	$0.03530
Opus 5.5	$0.00058	$0.01412
Sonnet 5.5	$0.00029	$0.00706
Haiku 4.5	$0.00015	$0.00353

Security

Grade A, and why

find-CNetChan_SendMessages-inlined 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 15d 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 — 254 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Find CNetChan_SendMessages (final-guarantee fallback)

Recover CNetChan::SendMessages in CS2 networksystem.dll / libnetworksystem.so using IDA Pro MCP tools.

This is the Agent fallback for the find-CNetChan_SendMessages-inlined skill. It runs only when the preprocessor returned failure. The preprocessor's inlined path locates the target by the xref string "SendMessage reliable failed AllocateMessage (%d).", which actually lives inside the shared helper CNetChan_SendMessages_Internal — so that anchor identifies the helper's callers, two of which exist (CNetChan::SendMessages and CNetChan::Transmit). When the sibling -noinline path cannot disambiguate them, this fallback is what resolves the real target.

Realworld Function References

Read the platform-relevant real-world YAMLs before searching in IDA. They provide concrete disassembly and semantic anchors for the neighbouring CNetChan vfuncs and document the decoy. Treat their addresses and offsets as reference-build values only; verify every result against the current binary.
