What it does
Mediator Reference is an agent skill from fullstackhero/dotnet-starter-kit. CQRS interface reference for FSH. This project uses the Mediator source generator, NOT MediatR. Reference when implementing commands, queries, and handlers.
Its SKILL.md is about 710 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Backend & APIs, covering Event-driven systems and Project scaffolding. The repository describes itself as: Production Grade Cloud-Ready .NET 10 Starter Kit (Web API + React Client) with Multitenancy Support, and Clean/Modular Architecture that saves roughly 200+ Development Hours! All… The licence is MIT.
When your agent uses it
- Tasks that involve Event-driven systems
- Tasks that involve Project scaffolding
Example prompts
- “/mediator-reference”
What it can do on your machine
Read from SKILL.md and the folder at commit 0bd98e3. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are csharp).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Mediator Reference loads about 709 tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 183 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Mediator Reference
⚠️ FSH uses the Mediator source-generator package (using Mediator;), NOT MediatR. Different
interfaces — MediatR types won't compile. The CQRS interfaces below are the library's own (no FSH wrapper).
Interfaces
| Purpose | ✅ Mediator (use) | ❌ MediatR (don't) |
|---|---|---|
| Command | ICommand<TResponse> | IRequest<TResponse> |
| Query | IQuery<TResponse> | IRequest<TResponse> |
| Command handler | ICommandHandler<TCommand, TResponse> | IRequestHandler<…> |
| Query handler | IQueryHandler<TQuery, TResponse> | IRequestHandler<…> |
| Notification / domain event | INotification (IDomainEvent : INotification) | INotification |
Pattern
// Command/Query → the Contracts project (Modules.{X}.Contracts/v1/{Area}/)
public sealed record Create{Entity}Command(string Name) : ICommand<Guid>;
// Handler → the runtime project (Modules.{X}/Features/v1/{Area}/{Feature}/), public sealed
public sealed class Create{Entity}CommandHandler({X}DbContext db)
: ICommandHandler<Create{Entity}Command, Guid>
{
public async ValueTask<Guid> Handle(Create{Entity}Command command, CancellationToken cancellationToken)
{
// …
}
}Rules: handlers return ValueTask<T> (not Task<T>); parameter named command/query (not request);
public sealed; .ConfigureAwait(false) on awaits. Send via mediator.Send(command, ct) (the IMediator
interface name matches MediatR's — that part is fine).
Registration — the four places
The source generator only scans assemblies listed in o.Assemblies, and that list exists in two host
files. A new module needs two markers (a Contracts type and the module type) added to the Mediator
list plus an entry in the moduleAssemblies array — in both FSH.Starter.Api/Program.cs and
FSH.Starter.DbMigrator/Program.cs:
builder.Services.AddMediator(o =>
{
o.ServiceLifetime = ServiceLifetime.Scoped;
o.Assemblies = [
/* … */
typeof(FSH.Modules.{X}.Contracts.{X}ContractsMarker), // Contracts assembly
typeof(FSH.Modules.{X}.{X}Module)]; // runtime assembly
});See add-module for the full procedure.
Common errors
| Symptom | Cause → fix |
|---|---|
IRequest<T> / IRequestHandler<,> not found | MediatR interface → use ICommand/IQuery + ICommandHandler/IQueryHandler |
Task<T> vs ValueTask<T> mismatch | Handler must return ValueTask<T> |
| Handler not invoked at runtime | Assembly missing from o.Assemblies (in one or both Program.cs files) |
