microsoft/win-dev-skills is a collection of AI-agent instructions and tools for creating native Windows applications with WinUI 3 and the Windows App SDK. Windows developers use it to guide agents through app development tasks from scaffolding and design to testing, packaging, and release. The catalogue entries are its agents, skills, and plugin components.
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.

Only the verdict fits; the numbers stay here.

windbg 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 installs
The manifest is a name and a version. 11 skills, 2 agents travel with it, and installing the plugin installs all of them — 643 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.
