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.

system-design-skills 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 8d 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": "system-design-skills",
"version": "1.0.0",
"description": "24 architecture skills for system design: 9 task skills that make design decisions (design-an-api, choose-a-datastore, scale-a-system, make-it-resilient, secure-the-system, design-a-payment-flow, choose-deployment-strategy, apply-a-reference-architecture, system-design-blueprint) plus 15 domain reference skills, all grounded in a bundled knowledge base distilled from ByteByteGo system-design-101. Task skills fire on design/creation intent and force implementation-level concreteness (real DB constraints, state machines, exact configs); reference skills answer concept lookups from the audited docs.",

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.
