The proof

I pointed the whole toolkit at a real production .NET 10 codebase

Real client project, so the name stays private. Here is some of what the AI caught.

No distributed tracing across services. Metrics only.
Only 1 of 75 endpoints actually required authorization.
Sensitive data logging left on in every environment.
In-memory filtering and N+1 queries hiding in the data layer.
No central package management across 30+ NuGet packages.

And the AI passed the parts that were already solid. No invented problems.


What you get

AI tools for every part of .NET

50+ AI tools, and growing

Architecture, EF Core, performance, observability, testing, security and DevOps. New tools added all the time.

Runs on your real code

A file, a folder, a whole project, or a GitHub link. It finds the relevant files itself. No pasting snippets.

AI code review for C#

Senior-level review, security audits and EF Core optimization with findings down to file and line.

Built on Claude, MCP-ready

Standard Claude skills and agents you can run in Claude Code or Cowork, designed to plug into MCP workflows.

A local dashboard

One self-contained page that catalogs everything in the toolkit plus your run history. Just ask it to open.

New AI tools every week

Something new or updated every week, and a changelog you can actually see.


Built for the AI-powered .NET developer

AI, .NET, agents, MCP and Claude - in one place

This is where .NET meets modern AI. Use AI agents for C# code review and security auditing, optimize Entity Framework Core queries, generate xUnit tests, wire up OpenTelemetry observability, and ship cleaner ASP.NET Core services. Everything is built as Claude skills and agents, designed to fit Model Context Protocol (MCP) workflows and the wider AI tooling you already use - so you can finally use AI on your real .NET projects, not toy examples. And the library keeps growing every week.

How it works

From install to senior-level output

STEP 01
01

Install a tool

Drop a skill or agent into your Claude / Cowork setup. One folder, zero dependencies.

STEP 02
02

Point it at your code

"Optimize the EF queries in src/Orders" or "Audit this repo for security". A file, folder, project, or GitHub link.

STEP 03
03

Get senior-level output

Findings with file and line, ranked by impact, with the fix. It even tells you what is already good.

FAQ

AI and .NET, answered

What is TheCodeMan AI Toolkit?

It is a growing library of AI tools for .NET developers - skills, agents and more - plus a community. They run on your real C# codebase and cover architecture, EF Core, performance, observability, testing, security and DevOps.

How do the AI tools work on my .NET code?

You point a tool at a target - a file, a folder, a whole project, or a GitHub link - and it finds the relevant files itself, then reports back like a senior engineer with findings down to file and line. You never paste code into a chat window.

Is it built on Claude and does it work with MCP?

Yes. The tools are standard Claude skills and agents you run in Claude Code or Cowork. They are designed to fit modern AI workflows, including Model Context Protocol (MCP) setups.

Can I use it for AI code review in C#?

Yes. There are dedicated tools for code review, security auditing (OWASP), architecture review, database performance and observability gaps - all tailored to .NET and C#.

Is my code safe?

The tools run inside your own AI tooling on the target you choose. You stay in control of what each one is pointed at.

Is there a free trial and can I cancel anytime?

Yes. You start with a 7-day free trial and can cancel anytime.
