A command for checking whether Steam player accounts have Valve Anti-Cheat (VAC) or other platform bans. It accepts SteamID64 numbers or Steam profile names and reports the results for multiple players.

Use it to screen player accounts, review VAC and game bans, check community or economy restrictions, and collect profile links.

It avoids checking each Steam account separately and puts ban details into one readable table.

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	$0.00013	$0.00305
Opus 5.5	$0.00005	$0.00122
Sonnet 5.5	$0.00003	$0.00061
Haiku 4.5	$0.00001	$0.00030

Security

Grade A, and why

vac 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 2mo 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.

What it actually says

Check ban status for: $ARGUMENTS

The argument is one or more Steam identifiers separated by spaces (SteamID64 or vanity URLs). Examples:

stealthylabs
gabelogannewell robinwalker
player1 player2 player3

Steps:

For any vanity URLs (non-numeric), use steam_get_player_summary to resolve names and SteamID64s
Collect all SteamID64s, then call steam_get_player_bans with the full list in one request
Call steam_get_player_summary for each ID to get display names (can batch if already resolved above)

Present the results as a clear table:

VAC / Ban Check

Player	SteamID	VAC Banned	VAC Bans	Game Bans	Community Ban	Economy	Days Since Ban

Use clear indicators:

No bans: "Clean"
VAC banned: "VAC x{N}" with days since last ban
Game banned: "Game x{N}"
Community banned: "Community"

After the table, add Steam profile links for each player:

{Name}: https://steamcommunity.com/profiles/{steamid64}

If any player has bans, add a note at the bottom summarizing the flagged accounts.

Changes

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.
