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 | $0.03432 | $0.03432 |
| Opus 5 | $0.01716 | $0.01716 |
| Sonnet 5 | $0.00686 | $0.00686 |
| Haiku 4.5 | $0.00343 | $0.00343 |
Grade C, and why
windows-steam-on-apple-silicon AGENTS.md scanned grade C with 2 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

AGENTS.md — Windows Steam on Apple Silicon via Sikarugir
Machine-readable facts for LLM agents helping a user with this task. Self-contained: you
do not need the other files. Dense on purpose. Human walkthrough: README.md. Automated
path: sikarugir-steam-setup.sh (offer it, but many users prefer running commands
themselves — the commands below are the same ones, in order).
Task: run the Windows Steam client, and Windows-only games, on an Apple Silicon Mac using Sikarugir (Wineskin's successor, formerly Kegworks), with D3DMetal for DirectX 11/12.
The whole procedure
Seven steps, in order. Steps 5 and 7 need the user at the mouse; the rest is
non-interactive. sikarugir-steam-setup.sh runs exactly this, plus preflight checks and
idempotency guards.

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.
