dotnet-backend-patterns

Master C#/.NET backend development patterns for building robust APIs, MCP servers, and enterprise applications. Covers async/await, dependency injection, Entity Framework Core, Dapper, configuration, caching, and testing with xUnit. Use when developing .NET backends, reviewing C# code, or designing API architectures.

Quality

Content

65%

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

The body is highly actionable with complete, executable C# examples, but it is verbose (re-teaching standard .NET concepts inline) and structurally monolithic — it duplicates detail that the provided reference and asset files are meant to hold, rather than acting as a lean overview pointing to them.

Suggestions

Trim inline tutorial commentary (DI lifetime explanations, async/await basics, the ConfigureAwait/.Result wrong-way callouts) since Claude already knows these; keep only the pattern decisions that are non-obvious.

Slim SKILL.md into an overview and move the full EF Core, Dapper, and multi-level caching implementations into the existing references/assets files, linking to them as one-level-deep detail.

Add a short sequenced workflow with explicit validation/checkpoint steps (e.g., build → run tests → verify) so the skill guides multi-step backend work rather than only cataloging patterns.

Dimension	Reasoning	Score
Conciseness	The ~815-line body re-teaches concepts Claude already knows (DI lifetimes, async/await, ConfigureAwait, blocking on .Result) with tutorial-style inline comments such as "// Scoped: One instance per HTTP request" and "// ❌ WRONG: Blocking on async (deadlock risk)"; it is mostly efficient but padded with unnecessary explanation.	2 / 3
Actionability	Provides fully executable, copy-paste-ready C# across DI registration, EF Core DbContext/configuration, Dapper repositories with real parameterized SQL, multi-level caching, and xUnit tests, matching the fully-executable anchor.	3 / 3
Workflow Clarity	This is a topical patterns catalog (Core Concepts, Data Access, Caching, Testing) with a 'When to Use' list and DO/DON'T guidance rather than a sequenced multi-step process, and it lacks the explicit validation checkpoints/feedback loops the rubric associates with a score of 3.	2 / 3
Progressive Disclosure	Bundle files exist and are correctly referenced in the Resources section (assets/service-template.cs, assets/repository-template.cs, references/ef-core-best-practices.md, references/dapper-patterns.md), but the SKILL.md body is a monolithic ~815 lines that inlines full EF Core, Dapper, and caching implementations that should live in those separate files — matching the 'content that should be separate is inline' anchor.	2 / 3

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.

The description is specific, complete, and well-triggered: it names concrete technologies and actions, includes an explicit 'Use when' clause with natural keywords, and occupies a distinct niche unlikely to conflict with other skills.

Dimension	Reasoning	Score
Specificity	Lists multiple specific concrete capabilities and technologies — "async/await, dependency injection, Entity Framework Core, Dapper, configuration, caching, and testing with xUnit" — rather than vague language, matching the comprehensive-actions anchor.	3 / 3
Completeness	Explicitly answers both what ("Master C#/.NET backend development patterns for building robust APIs, MCP servers, and enterprise applications") and when ("Use when developing .NET backends, reviewing C# code, or designing API architectures"), satisfying the explicit-trigger requirement.	3 / 3
Trigger Term Quality	Includes natural phrasing a user would actually say — "developing .NET backends, reviewing C# code, or designing API architectures" — plus common terms like C#/.NET, EF Core, Dapper, and xUnit, giving good coverage.	3 / 3
Distinctiveness Conflict Risk	Has a clear niche (C#/.NET backend patterns) with distinctive triggers (C# code, EF Core, Dapper, xUnit) that are unlikely to fire for unrelated skills.	3 / 3
	Total	12 / 12 Passed
