A command that examines a player's Steam library, including owned games, playtime, unplayed games, and recent activity. Steam is a store and online service for PC games.

Use it to review a player's library, identify games they have never started, list their most-played games, and describe their gaming preferences.

It turns a large game collection into a short view of the player's backlog, habits, most-played games, and recent activity.

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	$0.00017	$0.00314
Opus 5.5	$0.00007	$0.00126
Sonnet 5.5	$0.00003	$0.00063
Haiku 4.5	$0.00002	$0.00031

Security

Grade A, and why

library 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

Analyse the Steam library for: $ARGUMENTS

Do the following in parallel:

steam_get_owned_games with limit=500, sort_by="playtime", include_appinfo=true
steam_get_recently_played with count=10

Then compute and present:

Library Analysis - {Player}

Overview:

Total games owned: X
Games never launched (backlog): Y (Z%)
Games with > 100h: N
Total hours tracked: H

Top 10 Most Played: | # | Game | AppID | Playtime | (with store links: https://store.steampowered.com/app/{appid}/)

Backlog highlights (owned but 0 minutes played - show up to 10 random ones): | Game | AppID | Store |

Gamer profile (AI-generated based on the data): Write 2-3 sentences describing the player's gaming habits based on the genres/games visible in their top played list. Example: "You seem to favour long-form open-world games and competitive shooters, with a strong investment in simulation titles."

Recent activity (last 2 weeks): (from steam_get_recently_played)

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.
