The Problem
Claude Code is powerful, but out of the box it doesn't know your .NET conventions. It generates DateTime.Now instead of TimeProvider. It wraps EF Core in repository abstractions. It picks an architecture without asking about your domain. It reads entire source files when a Roslyn query would cost 10x fewer tokens.
dotnet-claude-kit fixes all of that.
What This Is
A curated knowledge and action layer that sits between Claude Code and your .NET project. Drop a single CLAUDE.md into your repo and Claude instantly knows:
- Which architecture fits your project (VSA, Clean Architecture, DDD, Modular Monolith)
- How to write modern C# 14 with primary constructors, collection expressions, and records
- How to build minimal APIs with
IEndpointGroup auto-discovery, TypedResults, and proper OpenAPI metadata
- How to use EF Core without repository wrappers, with compiled queries and interceptors
- How to test with
WebApplicationFactory + Testcontainers instead of in-memory fakes
- How to navigate your codebase via Roslyn semantic analysis instead of expensive file reads
- How to scaffold complete features, run health checks, review PRs, and enforce conventions
No configuration. No setup wizards. Just copy one file and go.
What Makes This 10x
v0.4.0 adds an action layer on top of the knowledge layer — Claude doesn't just know the right patterns, it actively applies them:
| Capability | What It Does |
|---|
| Scaffolding | One command → complete feature with Result pattern, validation (FluentValidation + filter wiring), OpenAPI metadata, pagination, CancellationToken, and tests. 9-point checklist enforced. All 4 architectures. |
| Interactive Setup | Guided project initialization: architecture questionnaire → tech stack selection → customized CLAUDE.md generation. |
| Health Check | Automated codebase analysis using MCP tools: anti-pattern scan, diagnostics, dead code detection, test coverage → graded report card. |
| PR Review | Multi-dimensional code review: anti-patterns, diagnostics, API surface changes, blast radius, architecture compliance, test coverage. |
| Convention Learning | Detects project-specific patterns (naming, structure, modifiers) and enforces them in new code. Adapts to your codebase. |
| Smart Tools | 15 Roslyn-powered MCP tools including dependency graphs, circular dependency detection, dead code finder, and test coverage mapping. |
| Active Hooks | 6 hooks for automated quality: format on edit, anti-pattern checks on commit, test result analysis, structure validation. |
Why dotnet-claude-kit?
| Metric | Without Kit | With Kit | Impact |
|---|
| Architecture decisions | Claude picks randomly | Asks questions, recommends with rationale | Correct architecture from day one |
| Code quality | Generic C#, legacy patterns | Modern C# 14 with idiomatic .NET 10 | Zero "fix this pattern" revision cycles |
| Codebase navigation | Reads entire files (500-2000+ tokens each) | Roslyn MCP queries (30-150 tokens each) | ~10x token savings on exploration |
| Anti-patterns generated | DateTime.Now, repository-over-EF, new HttpClient() | TimeProvider, direct DbContext, IHttpClientFactory | Production-ready on first generation |
| Testing approach | In-memory fakes, mocked everything | WebApplicationFactory + Testcontainers | Tests that catch real bugs |
| Production resilience | No retry, no circuit breakers | Polly v8 pipelines with telemetry | Handles transient failures automatically |
The result: Less time reviewing and correcting Claude's output. More time shipping features.
Installation
Plugin Install (Recommended)
Install as a Claude Code plugin — all 47 skills, 10 agents, 16 commands, 10 rules, hooks, and MCP config activate globally:
# In your terminal — install the Roslyn MCP server
dotnet tool install -g CWM.RoslynNavigator
Then inside a Claude Code session:
