agui-dotnet-protobuf

Use the protobuf wire transport (instead of the default Server-Sent Events) for an AG-UI connection with the AG-UI .NET SDK — a compact binary event stream negotiated via the Accept header. USE FOR: making an AGUIChatClient prefer protobuf by wiring an AGUIEventStreamHandler with ProtobufEventStreamFormatter (then SseEventStreamFormatter as fallback) into the HttpClient; enabling a server to answer protobuf by registering ProtobufEventStreamFormatter and negotiating the response format from the request Accept header; understanding the protobuf-or-SSE fallback. DO NOT USE FOR: the default SSE transport or first-time setup (use agui-dotnet-streaming-chat); JSON event serialization questions; tools, state, interrupts, multimodal, or generative UI.

Quality

Content

93%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

An efficient, highly actionable skill body with complete executable code for both sides of the transport and a solid verification section. The relative weak point is workflow clarity, which lacks an explicit validate-fix-retry loop, though no destructive or batch operation requires one.

Dimension	Reasoning	Score
Conciseness	Lean body that assumes .NET/HttpClient/ASP.NET Core competence; the only prose is AG-UI-specific protocol detail (Accept-header negotiation) rather than generic padding, and every section earns its place.	5 / 5
Actionability	Provides copy-paste-ready C# for both client (formatter-ordered AGUIEventStreamHandler) and server (per-request formatter selection from Accept), plus an install command and full endpoint wiring covering the common cases.	5 / 5
Workflow Clarity	Sections sequence cleanly (Install → Client → Server → Verify) and the Verify block gives three explicit validation checks including a fallback test, but there is no fix-and-retry feedback loop for failed validation.	4 / 5
Progressive Disclosure	Self-contained skill with no bundle files and no need for external references; content is organized into clearly headed sections (Goal, Install, Client, Server, Anti-patterns, Verify) with easy navigation and nothing buried.	5 / 5

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A highly specific, well-bounded description that clearly states what the skill does and when to use it, with strong negative-boundary guidance to avoid triggering for the default SSE path. The only soft spot is trigger-term quality, where implementation class names stand in for more natural user phrasings.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'wiring an AGUIEventStreamHandler with ProtobufEventStreamFormatter... into the HttpClient' and 'enabling a server to answer protobuf by registering ProtobufEventStreamFormatter and negotiating the response format from the request Accept header' — with comprehensive coverage of both client and server sides.	5 / 5
Completeness	Explicitly answers both 'what' (protobuf wire transport for AG-UI .NET, binary stream negotiated via Accept header) and 'when' via concrete 'USE FOR' / 'DO NOT USE FOR' clauses with specific trigger phrases.	5 / 5
Trigger Term Quality	Good natural-term coverage with synonyms ('protobuf' / 'compact binary event stream', 'SSE' / 'Server-Sent Events', 'fallback', 'transport', 'Accept header'), but several triggers are implementation class names (AGUIEventStreamHandler, ProtobufEventStreamFormatter) that users would not naturally voice.	4 / 5
Distinctiveness Conflict Risk	Occupies a clear niche (protobuf transport for AG-UI .NET) with an explicit 'DO NOT USE FOR' list and a pointer to the sibling skill agui-dotnet-streaming-chat, giving minimal conflict risk.	5 / 5
