dotnet-init

An interactive setup assistant for .NET projects using Claude Code. It identifies the project type, asks about its architecture and technology choices, and creates a tailored CLAUDE.md instruction file.

In plain words
What is it for?
It helps initialize new or existing .NET web APIs, Blazor apps, background workers, shared libraries, and modular monoliths.
Why use it?
It removes the need to determine the project structure and copy configuration templates by hand before starting work with Claude Code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dotnet-init 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.

/dotnet-init

What

Interactively initializes a .NET project for use with dotnet-claude-kit. Detects the project type, asks targeted questions about architecture and tech stack, then generates a fully customized CLAUDE.md in the project root.

No manual template copying required.

When

  • Starting a new .NET project with Claude Code
  • Adding dotnet-claude-kit to an existing project
  • "init project", "setup project", "generate CLAUDE.md", "configure for dotnet-claude-kit"

How

Step 1: Detect or Ask Project Type

Analyze the current directory to determine if this is an existing or greenfield project:

→ Look for .slnx / .sln files
→ If found, scan .csproj files for SDK type:
  - Microsoft.NET.Sdk.Web → web-api or blazor-app
  - Microsoft.NET.Sdk.Worker → worker-service
  - Microsoft.NET.Sdk → class-library
  - Multiple projects with inter-module references → modular-monolith
  - If ambiguous, ask the user

→ If NO solution/project found (greenfield):
  - Ask: "What are you building?"
    - REST API / microservice → web-api
    - Blazor application → blazor-app
    - Background worker / queue processor → worker-service
    - NuGet package / shared library → class-library
    - Multi-module system → modular-monolith
  - Ask: "Project name?"
  - Scaffold the solution structure:
    - dotnet new sln -n ProjectName --format slnx   (modern XML solution format)
    - dotnet new webapi / worker / classlib as appropriate
    - Set up Directory.Build.props with .NET 10 defaults
    - Create src/ and tests/ folder structure

Step 2: Architecture Questionnaire

Load the architecture-advisor skill and ask targeted questions:

  1. Domain complexity — CRUD-heavy, moderate business rules, or rich domain?
  2. Team size — Solo, small team, or large team?
  3. Module boundaries — Single deployable or multiple bounded contexts?
  4. Existing patterns — (existing projects only) Detect conventions via convention-learner skill

→ Recommend: VSA, Clean Architecture, DDD, or Modular Monolith with rationale.

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.
