agui-dotnet-wire-types

Add or modify a wire/protocol type in the AG-UI .NET SDK AGUI.Abstractions package — a new event, message, or content-part type, the AOT source-gen serializer context, or a polymorphic JSON converter, keeping it AOT-safe, JSON-wire-compatible with the TypeScript reference, and PublicAPI-clean. USE FOR: adding an AG-UI event type, adding a message role or input-content type, editing AGUIJsonSerializerContext, editing BaseEventJsonConverter / AGUIMessageJsonConverter / AGUIInputContentJsonConverter, fixing PublicAPI.Unshipped analyzer build failures on protocol types, wire-format round-trip serialization. DO NOT USE FOR: writing integration/SSE tests (use agui-dotnet-integration-tests), server hosting/endpoint code, or non-Abstractions packages.

Quality

Content

80%

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

An executable, lean protocol recipe with strong code examples and a clear multi-step sequence. Its main gaps are the missing explicit validation feedback loop and the absence of any progressive-disclosure reference split for a longish single-file skill.

Suggestions

Add an explicit feedback loop under 'Validate': 'If dotnet build or the round-trip test fails, fix the offending converter/PublicAPI registration and re-run both before proceeding.'

Consider splitting the PublicAPI.Unshipped.txt format detail and the full polymorphic converter pattern into a references file (e.g. PUBLICAPI.md / CONVERTERS.md) referenced from SKILL.md to shorten the inline body.

Surface the 'four coordinated spots' hard-rule checklist as an explicit pre-submit checklist the reader ticks off, mirroring the validation step.

DimensionReasoningScore

Conciseness

Dense and technical with no padding; it assumes Claude knows C#/System.Text.Json and does not explain what a JSON converter or AOT is — every line carries actionable rule or code.

3 / 3

Actionability

Provides copy-paste-ready C# property patterns, exact file paths, exact converter switch arms, exact PublicAPI lines, test code, and concrete 'dotnet build' / 'dotnet test' commands.

3 / 3

Workflow Clarity

The 6-step recipe and mandatory Validate section give a clear sequence with a checkpoint, but there is no explicit 'if build/test fails → fix → re-validate' recovery loop for an operation the doc itself calls out as silently breaking deserialization.

2 / 3

Progressive Disclosure

Well-sectioned but a single ~108-line inline document with no bundle reference files split out; over the 50-line simple-skill carve-out, so the all-inline structure is not ideal progressive disclosure.

Description

100%

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-triggered description with explicit use/exclusion guidance and third-person imperative voice. It cleanly names the package, the type of change, and the boundary against adjacent skills.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'Add or modify a wire/protocol type', 'new event, message, or content-part type, the AOT source-gen serializer context, or a polymorphic JSON converter' — rather than vague language.

3 / 3

Completeness

Explicitly answers both what (add/modify wire/protocol types, AOT-safe, JSON-wire-compatible, PublicAPI-clean) and when via an explicit 'USE FOR' trigger clause plus a 'DO NOT USE FOR' exclusion clause.

3 / 3

Trigger Term Quality

The 'USE FOR' list covers natural in-codebase triggers a developer would actually say: 'adding an AG-UI event type', 'fixing PublicAPI.Unshipped analyzer build failures', and the named converter/context types.

3 / 3

Distinctiveness Conflict Risk

A clear niche (AG-UI .NET SDK AGUI.Abstractions protocol types) with a 'DO NOT USE FOR' clause that disambiguates sibling skills like 'agui-dotnet-integration-tests', making wrong-skill triggering unlikely.
