A command for searching Steam, the PC game store, by game name or AppID and showing store details and current player counts when available.

Use it to find matching games, open their store pages, and check live player numbers for a known Steam AppID.

It avoids checking several Steam pages by hand when you want to identify a game or see how many people are playing it now.

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	$0.00015	$0.00175
Opus 5.5	$0.00006	$0.00070
Sonnet 5.5	$0.00003	$0.00035
Haiku 4.5	$0.00002	$0.00017

Security

Grade A, and why

game 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

Search for the Steam game: $ARGUMENTS

Do the following in parallel:

Use steam_search_game with the query to find matching games (limit: 5)
If the argument looks like a number (an AppID), also call steam_get_current_players with that AppID

Display the search results table, then for each result include a direct Steam store link:

Store page: https://store.steampowered.com/app/{appid}/

If you ran steam_get_current_players, show the live player count next to the matching game.

After the table, list the clickable Steam store links for each result:

{Game Name}: https://store.steampowered.com/app/{appid}/

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.
