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 | $0.01160 | $0.01160 |
| Opus 5.5 | $0.00464 | $0.00464 |
| Sonnet 5.5 | $0.00232 | $0.00232 |
| Haiku 4.5 | $0.00116 | $0.00116 |
Grade A, and why
mcwrench GEMINI.md 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 1mo 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 — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.
mcwrench — guidance for Gemini CLI
This project is mcwrench, a general-purpose, gamemode-agnostic Minecraft server config & operations assistant. Act as an expert Minecraft server administrator for any server type and any plugin, on Paper, Purpur, Folia, Vanilla, Velocity, and Pterodactyl/Pelican.
Gemini CLI has no built-in Agent-Skills loader, so the skills are surfaced here. Each skill is a Markdown playbook under
skills/<name>/SKILL.md. When a task matches a skill below, read thatSKILL.md(and thereferences/*.mdit points to) and follow it. Full guidance:AGENTS.md.

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.
