It helps analyse the Windows or Linux engine binary and recover the current function that synchronizes and waits for loading to finish.

It provides a recovery path when the normal preprocessor script cannot find the function. This avoids relying on stale addresses or signatures from a different engine build.

find-CEngineServer_SynchronizeAndBlockUntilLoaded

Q: What is find-CEngineServer_SynchronizeAndBlockUntilLoaded?

A binary-analysis fallback for locating the CEngineServer::SynchronizeAndBlockUntilLoaded function in Counter-Strike 2 engine files. It uses an IDA Pro analysis database and verifies the current virtual-function table and function behaviour.

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	$0.00078	$0.01696
Opus 5.5	$0.00031	$0.00678
Sonnet 5.5	$0.00016	$0.00339
Haiku 4.5	$0.00008	$0.00170

Security

Grade A, and why

find-CEngineServer_SynchronizeAndBlockUntilLoaded 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 13d 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.

Find CEngineServer_SynchronizeAndBlockUntilLoaded (Agent fallback)

Recover the single output of find-CEngineServer_SynchronizeAndBlockUntilLoaded using the assigned IDA Pro MCP database. The preprocessor ida_preprocessor_scripts/find-CEngineServer_SynchronizeAndBlockUntilLoaded.py remains the normal fast path.

Realworld Function References

Read the applicable current inputs and the annotated references below. Source-owned 14192 YAMLs and stored disassembly are reference-build evidence; verify addresses, slot indices and semantics in the assigned binary. Never copy a reference target YAML into the active output directory as a substitute for analysis.

ida_preprocessor_scripts/references/engine/CNetworkGameServerBase_SpawnGroupThink.windows.yaml
ida_preprocessor_scripts/references/engine/CNetworkGameServerBase_SpawnGroupThink.linux.yaml
bin_artifacts/14192/engine/CNetworkGameServerBase_SynchronizeAndBlockUntilLoaded.windows.yaml
bin_artifacts/14192/engine/CEngineServer_vtable.windows.yaml
bin_artifacts/14192/engine/CNetworkGameServerBase_SynchronizeAndBlockUntilLoaded.linux.yaml
bin_artifacts/14192/engine/CEngineServer_vtable.linux.yaml

Output inventory

Module: engine. Platform scope: Windows and Linux. Analyze only the platform of the assigned database; the runner invokes platforms separately.

Platform	Output filename	14192 reference entry	Reference slot / offset
windows	`CEngineServer_SynchronizeAndBlockUntilLoaded.windows.yaml`	`0x1800a1d40`	67 / `0x218`
linux	`CEngineServer_SynchronizeAndBlockUntilLoaded.linux.yaml`	`0x538440`	67 / `0x218`

Output metadata uses exactly vtable_name=CEngineServer_vtable; the concrete table artifact is CEngineServer_vtable.<platform>.yaml. Generate a validated function signature after identifying the current entry.

Step 0. Bind the task and skip an existing output

Call idb_list and reuse the database assigned by the runner. Confirm the input path, image base and platform with IDA; do not open, switch, close or quit the runner's database. The binary is engine2.dll / libengine2.so. Resolve the active artifact module directory from CS2VIBE_ARTIFACT_DIR (also visible inside IDA's environment). If unset, stop and request the assigned artifact directory; never write YAML beside the binary. For the current platform, skip the output if it already exists there and parses as a non-empty mapping. Do not overwrite a result produced by an earlier alternative.
