ag-ui-dotnet

A plugin containing .NET SDK skills for building AG-UI applications. AG-UI is a protocol for communication between AI agents and user interfaces.

In plain words
What is it for?
Use it when building .NET AG-UI apps involving streamed chat, server or client tools, human approvals, shared state, multimodal messages, reasoning traces, protobuf transport, or troubleshooting.
Why use it?
It groups guidance for common agent-app tasks in one place, so developers can follow the repository's conventions for streaming, tools, approvals, shared state, messages, and transport.

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.

Grade A, and why

ag-ui-dotnet 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 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.
