CS2_VibeSignatures: Skill for Claude Code

.claude/skills/find-CEntitySystem_m_entityNames/SKILL.md

find-CEntitySystem_m_entityNames is a skill for Claude Code from HLND2T/CS2_VibeSignatures. It costs 129 tokens per session (1,924 once invoked), scanned A, original, MIT.

A fallback procedure for finding CEntitySystem::m_entityNames, the part of Counter-Strike 2's entity system that maps entity names to entities. It examines the function that adds entities to this map, including cases where the compiler merged lookup code into that function.

In plain words
What is it for?
Use it to recover the missing structure-member offset in server.dll or libserver.so during Counter-Strike 2 binary analysis.
Why use it?
It helps recover the member's location when the normal automated finder fails because the compiler changed how the code is arranged. It requires checking the current binary instead of copying offsets from an older build.

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.

Security

Grade A, and why

find-CEntitySystem_m_entityNames 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 10d 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 — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Find CEntitySystem_m_entityNames (final-guarantee fallback)

Recover CEntitySystem::m_entityNames in CS2 server.dll / libserver.so using IDA Pro MCP tools. This is the Agent fallback for find-CEntitySystem_m_entityNames; it runs only after the preprocessor fails. Produce the missing struct-offset YAML even when the anonymous ordered-map lookup helper was inlined into CEntitySystem_AddEntityToNameMap and the expected sub_*(this + off + 8, this + off, &key) call no longer exists.

Realworld Function References

Read the platform-relevant YAML before searching in IDA. Treat every address and offset as a reference-build value only and verify it against the current binary.

  • ida_preprocessor_scripts/references/server/CEntitySystem_AddEntityToNameMap.windows.yaml
  • ida_preprocessor_scripts/references/server/CEntitySystem_AddEntityToNameMap.linux.yaml

The Linux reference includes both the historical lookup helper pseudocode and the predecessor pseudocode. Its a1 + 2800 annotation is an older-layout example; build 14168 moved the Linux member to 0xAF8. Never copy a reference displacement without checking the current function.

Background and semantic fingerprint

CEntitySystem_AddEntityToNameMap(this, identity) reads the entity-name key from identity + 0x18, returns when it is null, looks the key up in this->m_entityNames, and either appends the entity handle to an existing CEntityNameList or allocates a new 32-byte list and inserts it into the ordered map.

Identify this map operation by the whole fingerprint, not by an anonymous helper name:

  • the key comes from identity + 0x18;
  • RB-tree node indices use 0xFFFF as the null sentinel;
  • nodes are 24 bytes and compare their key field against the entity-name key;
  • the duplicate path calls _UtlRBTree_FailedInsertDuplicate or references the assertion text Found existing value when inserting into tree;
  • the new-value path allocates 32 bytes for the CEntityNameList and inserts the entity handle into it.

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.
