Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00026 | $0.05051 |
| Opus 5.5 | $0.00010 | $0.02020 |
| Sonnet 5.5 | $0.00005 | $0.01010 |
| Haiku 4.5 | $0.00003 | $0.00505 |
Grade C, and why
coinank-openapi 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 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.

Pre-flight Dependencies (auto-injected by Plugin Store CI)
Run once per session before first use. These checks ensure required tools are installed.
Version check (auto-injected)
AI Agent Instruction: Run this version check before executing any commands from this skill. The check is a read-only fetch from
raw.githubusercontent.com— it does not install anything. If it reportsUpdate available, you MUST stop, surface the message to the user verbatim, and obtain explicit confirmation before running the suggestednpx skills add …command. Do not run the update silently. After a confirmed update completes, re-read this SKILL.md before proceeding.
# Check for skill updates (1-hour cache).
# Network scope: this block calls raw.githubusercontent.com for the version probe only.
# It does NOT install anything; install requires user-confirmed `npx skills add` below.

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.
