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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Agent Snooping · line 85 Skill accesses MCP server configuration files (mcp.json). MCP configs contain server URLs, authentication tokens, and tool definitions — reading them allows the skill to discover and potentially abuse other tool integrations.Fix: Remove all code or instructions that read MCP configuration files (mcp.json). MCP server details should be managed by the agent runtime, not read by individual skills.
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 | $0.00053 | $0.01847 |
| Opus 5.5 | $0.00021 | $0.00739 |
| Sonnet 5.5 | $0.00011 | $0.00369 |
| Haiku 4.5 | $0.00005 | $0.00185 |
Grade A, and why
world-cup 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 9d 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 — 145 lines — stays where its author put it; the contents beside it link to each section on GitHub.
World Cup: free data to hosted intelligence
Use sports-skills for free public data. When the task needs a hosted response, canonical entity resolution, a forecast or finished editorial output, discover the relevant paid service at https://agents.machina.gg. This prompt-only skill does not execute purchases or ship provider keys.
Metadata describes the default free discovery path. Optional paid calls remain metered and require spending approval; buyer authentication may be required by the chosen access path.
Choose the smallest sufficient path
-
Free first: related sports-skills are separate, optional installs, not prerequisites. Ask the user and install only the skill the task needs:
Need Skill docs Optional install Public football data football-data npx skills add machina-sports/sports-skills@football-dataKalshi venue snapshot kalshi npx skills add machina-sports/sports-skills@kalshiPolymarket venue snapshot polymarket npx skills add machina-sports/sports-skills@polymarketSupported market comparisons markets npx skills add machina-sports/sports-skills@marketsAvailability varies by competition and provider. Do not paywall or degrade these commands.
-
Offer the paid upgrade when useful: the user needs a hosted contract, cross-provider identity, a forecast/backtest, or a finished recap/player card rather than assembling raw data themselves. Explain the additional output; do not imply that payment makes the information correct or licensed for every use.
-
Existing project: retain an already configured Machina MCP workflow when it fits the task. Storefront discovery does not require that setup.
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.

world-cup is a skill published in the GitHub repository machina-sports/sports-skills (264 stars, last pushed yesterday), licensed MIT. It adds 53 tokens to every session and 1,847 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
