find-CEngineServer_GetPlayerInfo-noinline

Agent fallback for CEngineServer_GetPlayerInfo-noinline (auto-generated, category: vfunc). Locate CEngineServer::GetPlayerInfo in the CS2 engine module via IDA Pro MCP and emit a fresh, minimal-unique artifact. The deterministic preprocessor could not resolve this symbol on the current gamever - your job is the re-sign. Trigger: CEngineServer_GetPlayerInfo-noinline, CEngineServer::GetPlayerInfo

Find CEngineServer_GetPlayerInfo-noinline

Target: CEngineServer::GetPlayerInfo (vfunc) in the module loaded in THIS session.

The old artifact/preprocessor anchors no longer match this build. Use anchors only to locate candidates; derive the artifact from the ACTUAL bytes you read. Produce ONLY this session's platform output. NEVER open another binary.

Method

Resolve the owning class vtable via RTTI (typeinfo-name string -> _ZTI object -> vtable). Identify the slot by xrefs from expected call sites. Slots commonly differ between platforms - never assume identical indices.

Mandatory self-check before emitting

The pipeline re-reads the bytes at your func_va and regenerates func_sig from them - a mismatch aborts the run. Therefore: read the real bytes via IDA MCP, derive the artifact FROM those bytes (wildcard relocated operands as ??), start at the TRUE function head, and only then write the YAML. A mismatch is always a bug in YOUR output.

Output schema (STRICT)

Write CEngineServer_GetPlayerInfo.{platform}.yaml with EXACTLY these fields:

func_name: <TASK>
func_va: "<hex virtual address>"
func_rva: "<hex rva>"
func_size: "<hex size>"
vtable_name: <owning class RTTI name>
vfunc_offset: "<hex vtable byte offset>"
vfunc_index: <decimal slot index>

NEVER include func_sig.

Verification

  1. Decompile and confirm the behavior matches the symbol's semantics.
  2. Uniqueness: the pattern must match exactly ONE location in the loaded binary.
  3. If no candidate can be confirmed, report the shortlist - a skipped symbol is safer than a wrong signature.

create-agent-skill-fallback

Free

Create an Agent SKILL.md fallback for an existing find-XXXX finder that relies on a fragile discovery foundation — above all LLM_DECOMPILE (patterns C/D/E), which matches the decompiled shape of a predecessor function against a stored reference and breaks when a symbol is inlined or de-inlined in a way the reference does not cover. The generated fallback coexists with the preprocessor and runs only when it returns failure, recovering every target robustly by decompiling the predecessor and following the inline/de-inline boundary with semantic anchors. Use when a finder broke on a game update, or you want to durably backstop one before it does. The recipe generalizes to any finder foundation. Triggers: create agent skill fallback, add SKILL.md fallback, robust fallback for finder, backstop LLM_DECOMPILE finder, final guarantee skill
