What is init-gamebin?

A repository command for preparing the exact CS2 game binaries and their local recovery files. CS2 is Counter-Strike 2, and BinSync is a tool for recovering shared binary-analysis data.

Use it when explicitly initializing or restoring binaries for a game version listed in `download.yaml`, with optional BinSync setup.

It prevents analysis from starting with the wrong game version or incomplete local binary data.

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	$0.00043	$0.01140
Opus 5.5	$0.00017	$0.00456
Sonnet 5.5	$0.00009	$0.00228

Security

Grade A, and why

init-gamebin 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 11d 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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Initialize Game Binaries

Use the repository-root script as the only entry point for downloading, merging, and depot fallback. Never overwrite an existing binary, substitute an unlisted version, or continue after a failed step. This skill handles only disposable binary/IDA state: never restore snapshot YAML into bin/ or hydrate tracked bin_artifacts. Source-owned symbol truth is already versioned under bin_artifacts/<GAMEVER>/.

Select GAMEVER

Extract an exact GAMEVER from the user's request. Resolve latest only when the user explicitly requests latest.
If the user did not specify a version, run:
```
uv run init_gamebin.py versions
```
Tell the user which entry is latest and ask: Which GAMEVER do you want to initialize? Wait for an explicit version before continuing.
Reject values absent from download.yaml; do not guess or silently use latest.

Decide IDB Download

A rebuilt Release also publishes gamebin-with-idb-<GAMEVER>.7z, its warm IDA databases. Downloading it skips the slow, resource-heavy local warmup. Decide before preparing binaries:

Probe whether the selected GAMEVER publishes the archive:
```
uv run init_gamebin.py check-idb <GAMEVER>
```
If the probe exits 0 (available), ask the user whether to download the IDB-bundled gamebin and wait for an explicit yes/no.
- Yes → prepare with --with-idb. The warm databases are merged into bin/<GAMEVER> and the "Warm Up IDB" step below is skipped (the binaries are already warm).
- No → prepare without the flag and keep the "Warm Up IDB" step below.
If the probe exits 1 (unavailable), tell the user which GAMEVER publishes no warm IDB archive and why, then prepare without the flag and keep the "Warm Up IDB" step below. Do not retry.

A tracked (rebuild-free) release is published without any IDA analysis and therefore never carries this archive; --with-idb also fails loudly for a GAMEVER whose Release declares none.

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.
