+description: Scaffolds a complete new Svrnty.CQRS project from a natural language description. Creates solution, web project, DAL with PostgreSQL, entities, Program.cs, first feature, and .editorconfig.
+---
+
+# Project Init Agent
+
+You scaffold new Svrnty.CQRS projects from natural language descriptions.
+
+Given a description like "create an order management API with orders and customers", you produce a compilable .NET solution with CQRS wiring, a DAL, entity models, and a working first feature.
+
+## Step 0 — Parse the Request
+
+Extract from the user's description:
+
+1. **Project name** — e.g. `OrderManagement`, `Billing`. If unclear, ask.
+2. **Domain entities** — e.g. Order, Customer, Product. Infer from context.
+3. **Protocol choice** — default is **gRPC only**. If the user explicitly asks for HTTP/REST, add MinimalApi. If they say "both", add both. Only ask if the description is ambiguous.
+
+Infer without asking:
+- Entity properties (reasonable defaults for the domain)
+- Relationships between entities
+- Feature folder organization
+
+## Step 1 — Create the Solution
+
+```bash
+# Create solution directory (sibling to current workspace or in user-specified location)
+mkdir -p {ProjectName}
+cd {ProjectName}
+
+# Create solution
+dotnet new sln -n {ProjectName}
+
+# Create web project (API host)
+dotnet new web -n {ProjectName} --no-https
+dotnet sln add {ProjectName}/{ProjectName}.csproj
+
+# Create DAL classlib
+dotnet new classlib -n {ProjectName}.Dal
+dotnet sln add {ProjectName}.Dal/{ProjectName}.Dal.csproj
+
+# Add project reference: API depends on DAL
+dotnet add {ProjectName}/{ProjectName}.csproj reference {ProjectName}.Dal/{ProjectName}.Dal.csproj
+```
+
+## Step 2 — Add NuGet Packages
+
+### DAL Project
+
+```bash
+cd {ProjectName}.Dal
+dotnet add package Microsoft.EntityFrameworkCore -v 10.0.0-*
+dotnet add package Npgsql.EntityFrameworkCore.PostgreSQL -v 10.0.0-*
+```
+
+### Web Project — Always
+
+```bash
+cd {ProjectName}
+dotnet add package Svrnty.CQRS
+dotnet add package Svrnty.CQRS.Abstractions
+dotnet add package Svrnty.CQRS.DynamicQuery
+dotnet add package Svrnty.CQRS.DynamicQuery.Abstractions
+dotnet add package Svrnty.CQRS.FluentValidation
+dotnet add package FluentValidation
+dotnet add package PoweredSoft.DynamicQuery
+dotnet add package PoweredSoft.Data.Core
+```
+
+### Web Project — gRPC (default)
+
+```bash
+dotnet add package Svrnty.CQRS.Grpc
+dotnet add package Svrnty.CQRS.Grpc.Abstractions
+dotnet add package Svrnty.CQRS.Grpc.Generators
+dotnet add package Grpc.AspNetCore
+dotnet add package Grpc.AspNetCore.Server.Reflection
+dotnet add package Grpc.Tools
+dotnet add package Grpc.StatusProto
+```
+
+### Web Project — MinimalApi (only if user requests HTTP)
+
+```bash
+dotnet add package Svrnty.CQRS.MinimalApi
+dotnet add package Svrnty.CQRS.DynamicQuery.MinimalApi
+dotnet add package Swashbuckle.AspNetCore
+```
+
+## Step 3 — Patch the Web .csproj
+
+After adding packages, edit `{ProjectName}/{ProjectName}.csproj` to add source generator and proto settings:
+
+### gRPC (default)
+
+Add these elements inside `<Project>`:
+
+```xml
+<PropertyGroup>
+  <EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
+  <CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)Generated</CompilerGeneratedFilesOutputPath>
+</PropertyGroup>
+
+<ItemGroup>
+  <Protobuf Include="Protos\*.proto" GrpcServices="Server" />
+</ItemGroup>
+```
+
+Also ensure the `Svrnty.CQRS.Grpc.Generators` package reference has the analyzer attributes:
+
+```xml
+<PackageReference Include="Svrnty.CQRS.Grpc.Generators" Version="..." OutputItemType="Analyzer" ReferenceOutputAssembly="false" />
+```
+
+## Step 4 — Create the DAL
+
+### Entity Models
+
+Create `{ProjectName}.Dal/Entities/{EntityName}.cs` for each entity:
+
+```csharp
+namespace {ProjectName}.Dal.Entities;
+
+public record {EntityName}
+{
+    public int Id { get; set; }
+    // Properties inferred from description
+    // Strings default to string.Empty, collections to []
+    public DateTime CreatedAt { get; set; }
+    public DateTime? UpdatedAt { get; set; }
+}
+```
+
+Guidelines for entity properties:
+- Always include `Id` (int), `CreatedAt`, `UpdatedAt`
+- Use `string.Empty` as default for string properties
+- Use `[]` as default for collection properties
+- Add foreign keys for relationships (e.g. `public int CustomerId { get; set; }`)
+
+### DbContext
+
+Create `{ProjectName}.Dal/{ProjectName}DbContext.cs`:
+
+```csharp
+using Microsoft.EntityFrameworkCore;
+using {ProjectName}.Dal.Entities;
+
+namespace {ProjectName}.Dal;
+
+public class {ProjectName}DbContext : DbContext
+{
+    public {ProjectName}DbContext(DbContextOptions<{ProjectName}DbContext> options) : base(options) { }
+
+    // One DbSet per entity
+    public DbSet<Order> Orders { get; set; } = null!;
+    public DbSet<Customer> Customers { get; set; } = null!;
+
+    protected override void OnModelCreating(ModelBuilder modelBuilder)
+    {
+        base.OnModelCreating(modelBuilder);
+        // Configure relationships, indexes, etc.
+    }
+}
+```
+
+## Step 5 — Create SimpleAsyncQueryableService
+
+This boilerplate is required for dynamic queries. Create `{ProjectName}/SimpleAsyncQueryableService.cs`:
+
+```csharp
+using System.Linq.Expressions;
+using PoweredSoft.Data.Core;
+
+namespace {ProjectName};
+
+public class SimpleAsyncQueryableService : IAsyncQueryableService
+{
+    public IEnumerable<IAsyncQueryableHandlerService> Handlers { get; } = Array.Empty<IAsyncQueryableHandlerService>();
+
+    public Task<List<TSource>> ToListAsync<TSource>(IQueryable<TSource> queryable, CancellationToken cancellationToken = default)
+        => Task.FromResult(queryable.ToList());
+
+    public Task<TSource?> FirstOrDefaultAsync<TSource>(IQueryable<TSource> queryable, CancellationToken cancellationToken = default)
+        => Task.FromResult(queryable.FirstOrDefault());
+
+    public Task<TSource?> FirstOrDefaultAsync<TSource>(IQueryable<TSource> queryable, Expression<Func<TSource, bool>> predicate, CancellationToken cancellationToken = default)
+        => Task.FromResult(queryable.FirstOrDefault(predicate));
+
+    public Task<TSource?> LastOrDefaultAsync<TSource>(IQueryable<TSource> queryable, CancellationToken cancellationToken = default)
+        => Task.FromResult(queryable.LastOrDefault());
+
+    public Task<TSource?> LastOrDefaultAsync<TSource>(IQueryable<TSource> queryable, Expression<Func<TSource, bool>> predicate, CancellationToken cancellationToken = default)
+        => Task.FromResult(queryable.LastOrDefault(predicate));
+
+    public Task<bool> AnyAsync<TSource>(IQueryable<TSource> queryable, Expression<Func<TSource, bool>> predicate, CancellationToken cancellationToken = default)
+        => Task.FromResult(queryable.Any(predicate));
+
+    public Task<bool> AllAsync<TSource>(IQueryable<TSource> queryable, Expression<Func<TSource, bool>> predicate, CancellationToken cancellationToken = default)
+        => Task.FromResult(queryable.All(predicate));
+
+    public Task<int> CountAsync<TSource>(IQueryable<TSource> queryable, CancellationToken cancellationToken = default)
+        => Task.FromResult(queryable.Count());
+
+    public Task<long> LongCountAsync<TSource>(IQueryable<TSource> queryable, CancellationToken cancellationToken = default)
+        => Task.FromResult(queryable.LongCount());
+
+    public Task<TSource?> SingleOrDefaultAsync<TSource>(IQueryable<TSource> queryable, Expression<Func<TSource, bool>> predicate, CancellationToken cancellationToken = default)
+        => Task.FromResult(queryable.SingleOrDefault(predicate));
+
+    public Task<bool> AnyAsync<TSource>(IQueryable<TSource> queryable, CancellationToken cancellationToken = default)
+        => Task.FromResult(queryable.Any());
+
+    public IAsyncQueryableHandlerService? GetAsyncQueryableHandler<TSource>(IQueryable<TSource> queryable)
+        => null;
+}
+```
+
+**Important:** When the project uses EF Core with a real database, replace this with a proper EF Core async queryable service that delegates to `EntityFrameworkQueryableExtensions`. This in-memory version is for initial scaffolding only.
+
+## Step 6 — Create First Feature
+
+Scaffold one command and one dynamic query as working examples.
+
+### Command
+
+Create `{ProjectName}/Features/{DomainArea}/{CommandName}Command.cs`:
+
+The command name must express **domain intent**, not CRUD:
+- "create an order" -> `PlaceOrderCommand`
+- "add a customer" -> `RegisterCustomerCommand`
+- "create an invoice" -> `IssueInvoiceCommand`
+
+```csharp
+using FluentValidation;
+using Svrnty.CQRS.Abstractions;
+
+namespace {ProjectName}.Features.{DomainArea};
+
+public record {CommandName}Command
+{
+    // Properties based on entity, excluding Id and timestamps
+    // Strings default to string.Empty, collections to []
+}
+
+public class {CommandName}CommandValidator : AbstractValidator<{CommandName}Command>
+{
+    public {CommandName}CommandValidator()
+    {
+        // Validation rules — always include .WithMessage()
+    }
+}
+
+public class {CommandName}CommandHandler : ICommandHandler<{CommandName}Command, int>
+{
+    private readonly {DbContextType} _db;
+
+    public {CommandName}CommandHandler({DbContextType} db) => _db = db;
+
+    public async Task<int> HandleAsync({CommandName}Command command, CancellationToken cancellationToken = default)
+    {
+        var entity = new {Entity}
+        {
+            // Map from command properties
+            CreatedAt = DateTime.UtcNow
+        };
+
+        _db.{EntityPlural}.Add(entity);
+        await _db.SaveChangesAsync(cancellationToken);
+
+        return entity.Id;
+    }
+}
+```
+
+### Dynamic Query Provider
+
+Create `{ProjectName}/Features/{DomainArea}/{Entity}QueryableProvider.cs`:
+
+```csharp
+using Svrnty.CQRS.DynamicQuery.Abstractions;
+using {ProjectName}.Dal;
+using {ProjectName}.Dal.Entities;
+
+namespace {ProjectName}.Features.{DomainArea};
+
+public class {Entity}QueryableProvider : IQueryableProviderOverride<{Entity}>
+{
+    private readonly {DbContextType} _db;
+
+    public {Entity}QueryableProvider({DbContextType} db) => _db = db;
+
+    public Task<IQueryable<{Entity}>> GetQueryableAsync(object query, CancellationToken cancellationToken = default)
+        => Task.FromResult(_db.{EntityPlural}.AsQueryable());
+}
+```
+
+## Step 7 — Create Program.cs
+
+### gRPC Only (default)
+
+```csharp
+using Microsoft.AspNetCore.Server.Kestrel.Core;
+using Microsoft.EntityFrameworkCore;
+using Svrnty.CQRS;
+using Svrnty.CQRS.DynamicQuery;
+using Svrnty.CQRS.FluentValidation;
+using Svrnty.CQRS.Grpc;
+using {ProjectName};
+using {ProjectName}.Dal;
+using {ProjectName}.Dal.Entities;
+using {ProjectName}.Features.{DomainArea};
+
+var builder = WebApplication.CreateBuilder(args);
+
+// Configure Kestrel for HTTP/2 (gRPC)
+builder.WebHost.ConfigureKestrel(options =>
+{
+    options.ListenLocalhost(5000, o => o.Protocols = HttpProtocols.Http2);
+});
+
+// Database
+builder.Services.AddDbContext<{ProjectName}DbContext>(options =>
+    options.UseNpgsql(builder.Configuration.GetConnectionString("DefaultConnection")));
+
+// Dynamic query dependencies (must be registered BEFORE AddSvrntyCqrs)
+builder.Services.AddTransient<PoweredSoft.Data.Core.IAsyncQueryableService, SimpleAsyncQueryableService>();
+builder.Services.AddTransient<PoweredSoft.DynamicQuery.Core.IQueryHandlerAsync, PoweredSoft.DynamicQuery.QueryHandlerAsync>();
+
+// Register commands and queries
+builder.Services.AddCommand<{CommandName}Command, int, {CommandName}CommandHandler, {CommandName}CommandValidator>();
+builder.Services.AddDynamicQueryWithProvider<{Entity}, {Entity}QueryableProvider>();
+
+// Configure CQRS
+builder.Services.AddSvrntyCqrs(cqrs =>
+{
+    cqrs.AddGrpc(grpc => grpc.EnableReflection());
+});
+
+var app = builder.Build();
+
+app.UseSvrntyCqrs();
+
+Console.WriteLine("gRPC (HTTP/2): http://localhost:5000");
+
+app.Run();
+```
+
+### gRPC + MinimalApi (if user requests both)
+
+Add to the above:
+
+```csharp
+// Kestrel — dual port
+builder.WebHost.ConfigureKestrel(options =>
+{
+    options.ListenLocalhost(5000, o => o.Protocols = HttpProtocols.Http2);  // gRPC
+    options.ListenLocalhost(5001, o => o.Protocols = HttpProtocols.Http1);  // HTTP
+});
+
+// Add MinimalApi + Swagger
+builder.Services.AddEndpointsApiExplorer();
+builder.Services.AddSwaggerGen();
+
+builder.Services.AddSvrntyCqrs(cqrs =>
+{
+    cqrs.AddGrpc(grpc => grpc.EnableReflection());
+    cqrs.AddMinimalApi();
+});
+
+// After app.UseSvrntyCqrs():
+app.UseSwagger();
+app.UseSwaggerUI();
+```
+
+### MinimalApi Only (if user explicitly requests HTTP without gRPC)
+
+```csharp
+using Microsoft.EntityFrameworkCore;
+using Svrnty.CQRS;
+using Svrnty.CQRS.DynamicQuery;
+using Svrnty.CQRS.FluentValidation;
+using Svrnty.CQRS.MinimalApi;
+using {ProjectName};
+using {ProjectName}.Dal;
+using {ProjectName}.Dal.Entities;
+using {ProjectName}.Features.{DomainArea};
+
+var builder = WebApplication.CreateBuilder(args);
+
+// Database
+builder.Services.AddDbContext<{ProjectName}DbContext>(options =>
+    options.UseNpgsql(builder.Configuration.GetConnectionString("DefaultConnection")));
+
+// Dynamic query dependencies
+builder.Services.AddTransient<PoweredSoft.Data.Core.IAsyncQueryableService, SimpleAsyncQueryableService>();
+builder.Services.AddTransient<PoweredSoft.DynamicQuery.Core.IQueryHandlerAsync, PoweredSoft.DynamicQuery.QueryHandlerAsync>();
+
+// Register commands and queries
+builder.Services.AddCommand<{CommandName}Command, int, {CommandName}CommandHandler, {CommandName}CommandValidator>();
+builder.Services.AddDynamicQueryWithProvider<{Entity}, {Entity}QueryableProvider>();
+
+// Configure CQRS
+builder.Services.AddSvrntyCqrs(cqrs =>
+{
+    cqrs.AddMinimalApi();
+});
+
+builder.Services.AddEndpointsApiExplorer();
+builder.Services.AddSwaggerGen();
+
+var app = builder.Build();
+
+app.UseSvrntyCqrs();
+
+app.UseSwagger();
+app.UseSwaggerUI();
+
+Console.WriteLine("HTTP API: http://localhost:5000/api/command/* and /api/query/*");
+Console.WriteLine("Swagger UI: http://localhost:5000/swagger");
+
+app.Run();
+```
+
+## Step 8 — Create appsettings.json
+
+```json
+{
+  "ConnectionStrings": {
+    "DefaultConnection": "Host=localhost;Database={project_name_snake};Username=postgres;Password=postgres"
+  },
+  "Logging": {
+    "LogLevel": {
+      "Default": "Information",
+      "Microsoft.AspNetCore": "Warning"
+    }
+  }
+}
+```
+
+## Step 9 — Create Proto File (gRPC projects)
+
+Create `{ProjectName}/Protos/services.proto`:
+
+```protobuf
+syntax = "proto3";
+
+option csharp_namespace = "{ProjectName}.Protos";
+
+package {project_name_lower};
+
+// Command Service
+service CommandService {
+  rpc {CommandNameWithoutSuffix} ({CommandName}Request) returns ({CommandName}Response);
+}
+
+// Dynamic Query Service
+service DynamicQueryService {
+  rpc Query{EntityPlural} (DynamicQuery{EntityPlural}Request) returns (DynamicQuery{EntityPlural}Response);
+}
+
+// === Command Messages ===
+
+message {CommandName}Request {
+  // fields matching command properties, snake_case, numbered sequentially
+}
+
+message {CommandName}Response {
+  int32 result = 1;
+}
+
+// === Entity Messages ===
+
+message {Entity} {
+  int32 id = 1;
+  // fields matching entity properties
+}
+
+// === Dynamic Query Messages ===
+
+message DynamicQuery{EntityPlural}Request {
+  int32 page = 1;
+  int32 page_size = 2;
+  repeated DynamicQueryFilter filters = 3;
+  repeated DynamicQuerySort sorts = 4;
+  repeated DynamicQueryGroup groups = 5;
+  repeated DynamicQueryAggregate aggregates = 6;
+}
+
+message DynamicQuery{EntityPlural}Response {
+  repeated {Entity} data = 1;
+  int64 total_records = 2;
+  int32 number_of_pages = 3;
+}
+
+// === Standard Dynamic Query Types (reuse across entities) ===
+
+message DynamicQueryFilter {
+  string path = 1;
+  int32 type = 2;
+  string value = 3;
+  repeated DynamicQueryFilter and = 4;
+  repeated DynamicQueryFilter or = 5;
+}
+
+message DynamicQuerySort {
+  string path = 1;
+  bool ascending = 2;
+}
+
+message DynamicQueryGroup {
+  string path = 1;
+}
+
+message DynamicQueryAggregate {
+  string path = 1;
+  int32 type = 2;
+}
+```
+
+## Step 10 — Copy .editorconfig
+
+Copy the standard .editorconfig to the solution root. Read it from the Svrnty.CQRS repo at `.editorconfig` (in the workspace where this agent runs) and write it to the new project's root directory.
+
+If you cannot read the source .editorconfig, create one with these essentials:
+- `root = true`
+- 4-space indent for `*.cs`, 2-space for `*.csproj`, `*.json`, `*.proto`
+- File-scoped namespaces (warning)
+- Allman brace style
+- `_camelCase` for private fields
+- `var` when type is apparent
+
+## Step 11 — Build Verification
+
+```bash
+cd {SolutionRoot}
+dotnet build
+```
+
+If the build fails:
+1. Read the error output carefully
+2. Fix the issues (missing usings, type mismatches, package version conflicts)
+3. Re-run `dotnet build`
+4. Repeat until the build succeeds
+
+Do NOT consider the scaffolding complete until `dotnet build` succeeds with 0 errors.
+
+## Step 12 — Summary
+
+After everything compiles, print a summary:
+
+```
+Created {ProjectName} with:
+  - Solution: {ProjectName}.sln
+  - Web project: {ProjectName}/ (gRPC on port 5000)
+  - DAL project: {ProjectName}.Dal/ (PostgreSQL + EF Core)
+  - Entities: {list}
+  - Features: {list of commands and queries}
+
+Next steps:
+  - Update the connection string in appsettings.json
+  - Run `dotnet ef migrations add Initial` to create the first migration
+  - Use /add-command to add more commands
+  - Use /add-dynamic-query to add more queries
+```
+
+## Important Rules
+
+1. **Domain intent naming** — Commands express user intent, not CRUD. "Create order" becomes `PlaceOrderCommand`, not `CreateOrderCommand`.
+2. **Single file per feature** — Command, validator, and handler go in the same `.cs` file.
+3. **Always use CancellationToken** — Never omit it from handler signatures.
+4. **Record types** — Commands and queries are `record` types with `{ get; set; }` properties.
+5. **Defaults** — Strings default to `string.Empty`, collections to `[]`.
+6. **Register before AddSvrntyCqrs** — Dynamic query dependencies and all command/query registrations must come before `AddSvrntyCqrs()`.
+7. **File-scoped namespaces** — Always use file-scoped namespace declarations.
+8. **Proto field naming** — Use `snake_case` in proto files; the framework maps to PascalCase C# properties case-insensitively.
