## What it does

The skill starts by detecting the project's architecture — Vertical Slice, Clean Architecture, DDD or Modular Monolith. Then it reads your existing conventions: class naming, folder layout, validation approach, test project structure. Only after that does it generate files from the templates for that architecture.

A nine-item checklist gates every feature. Endpoint via `IEndpointGroup`, `sealed` handler with a primary constructor, FluentValidation rules, DTO records, `IEntityTypeConfiguration<T>`, integration tests on `WebApplicationFactory` plus Testcontainers, OpenAPI metadata, `CancellationToken` on every async call, and the `Result<T>` pattern. Nothing gets skipped — the skill will not hand you half a feature.

Once files are written it builds and runs the tests with `dotnet build --no-restore` and `dotnet test --no-build --filter "FullyQualifiedName~{FeatureName}"`. If either fails, it fixes and re-runs before reporting back. You need the .NET 10 SDK, and since the integration tests use Testcontainers, Docker has to be available on the machine.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill scaffold -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/scaffold/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/scaffold/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill scaffold -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/scaffold/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill scaffold -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/scaffold/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install codewithmukesh/dotnet-claude-kit scaffold
```

2. **Manually: put the files in place**
- File: `.github/skills/scaffold/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill scaffold -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/codewithmukesh/dotnet-claude-kit --path skills/scaffold
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/scaffold/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill scaffold -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/codewithmukesh/dotnet-claude-kit/tree/HEAD/skills/scaffold/SKILL.md

## When to use it
- create an endpoint with its handler and validator in one pass
- place new feature files across Clean Architecture layers
- generate CRUD for an entity together with its EF configuration
- add an integration test to every new feature
- match generation to conventions the codebase already follows

## Example prompts
- /scaffold a Product Catalog feature with CRUD
- create an endpoint for orders in Vertical Slice style
- add an Invoice entity with fields and invariants

  Architecture-aware feature scaffolding for .NET 10 projects. Detects the

  the completeness checklist and per-architecture code templates every

# /scaffold — Architecture-Aware Feature Scaffolding

## What

Generates a complete feature with all required files based on the project's
architecture. Never generates half a feature — every scaffold includes the
endpoint, handler, validation, DTOs, EF configuration, and at least one
integration test as a single unit, written in modern C# 14 (primary
constructors, collection expressions, records, sealed handlers, TypedResults).

Supported architectures (file placement maps and code shape templates live in
`references/architecture-patterns.md`):

- **Vertical Slice Architecture (VSA)** — single-file features in `Features/`
- **Clean Architecture (CA)** — files split across Domain, Application, Infrastructure, Api
- **DDD + Clean Architecture** — aggregate roots, value objects, domain events, plus CA layers
- **Modular Monolith** — self-contained modules with their own DbContext and integration events

## When

- "Scaffold a [feature name]", "create an endpoint for", "add a feature"
- "Generate CRUD for", "add entity", "new module", "scaffold a module"
- Starting a new feature after `/plan` has produced an approved plan
- Customizing generation templates or defining what a complete slice includes
- Any time the user wants a complete, working feature skeleton

## How

### Step 1: Detect Architecture

Use the `architecture-advisor` skill to determine the project's architecture:
- Examine folder structure, project references, and existing patterns
- If architecture is ambiguous, ask the user rather than guessing
- Load the matching architecture skill (vertical-slice, clean-architecture, ddd)

### Step 2: Clarify Scope

Confirm with the user before generating (skip anything the plan already answers):
1. Feature/entity name and operations needed — full CRUD or a subset?
2. Key fields and invariants for any new entity
3. Module placement (Modular Monolith only) — existing module or new one?

### Step 3: Learn Conventions

Use the `convention-learner` skill and MCP tools to check:
```
