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.

han-plugin-builder 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": "han-plugin-builder",
"description": "Guidance and tooling for building Claude Code skills and plugins. Carries the full body of skill-authoring, agent-authoring, and plugin-configuration guidance, and an init step that vendors that guidance into any repo as a path-scoped rule index so contributors get the right guidance loaded for the file they are editing. Standalone and opt-in: depends on nothing and is not bundled by the han meta-plugin.",
"version": "2.2.0"
}
What it installs
The manifest is a name and a version. 4 skills travel with it, and installing the plugin installs all of them — 505 tokens a session between them. Each is measured on its own page, and each can be installed alone.
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.
