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 | $0.00086 | $0.04991 |
| Opus 5 | $0.00043 | $0.02495 |
| Sonnet 5 | $0.00017 | $0.00998 |
| Haiku 4.5 | $0.00009 | $0.00499 |
Grade A, and why
openfootball scanned grade A with 1 finding 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 10d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

openfootball / football.json API
openfootball is a free, open, public domain collection of football (soccer) data. The football.json repository provides pre-built JSON files for major leagues and tournaments worldwide. No API key or authentication is required.
Data Sources
There are two ways to access the data:
1. Raw GitHub URLs (Primary)
https://raw.githubusercontent.com/openfootball/football.json/master/{season}/{league}.json
2. GitHub Pages Mirror
https://openfootball.github.io/{country}/{season}/{league-name}.json
Recommendation: Use the raw GitHub URLs for the
football.jsonrepo — they use a simple, consistent naming convention and are the most reliable.

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
