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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

game-development 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 3d 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.
What it actually says
{
"name": "game-development",
"source": "./skills/game-development",
"description": "Game development orchestrator that routes to platform-specific skills based on project needs. Use when building games or game-related systems."
}What it installs
The manifest is a name and a version. 11 skills travel with it, and installing the plugin installs all of them — 206 tokens a session between them. Each is measured on its own page, and each can be installed alone.
- Skill game-development A 27 tokens
- Skill pc-games A 19 tokens
- Skill web-games A 20 tokens
- Skill 3d-games A 18 tokens
- Skill multiplayer A 15 tokens
- Skill game-audio A 18 tokens
- Skill game-design A 18 tokens
- Skill game-art A 17 tokens
- Skill vr-ar A 16 tokens
- Skill 2d-games A 20 tokens
- Skill mobile-games A 18 tokens
What ships with it
1 file beside marketplace.json#game-development 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.
