  • 4 specialist .mdc rules engineered for C#/.NET
  • Stateful LEARNING_LOG.md protocol — the "brain" of your project
  • Drop-in install. Zero config. Works in 60 seconds.
  • One-time payment. Lifetime updates. No subscription.

The Hidden Cost

You're Paying the "Context Tax" Every Single Morning.

Be honest. The first 15 minutes of every Cursor session, you're not coding — you're re-explaining your codebase to a goldfish.

15 mins/day, lost to re-context

That's 62 hours a year typing the same "we use Mediator and Result<T> in this project…" preamble. Your senior salary deserves better.

🧠

The AI "drifts" by Wednesday

By mid-week it's suggesting HttpClient instantiations in your repository layer. Generic prompts can't enforce your SOLID boundaries.

🌀

Hallucination loops cost hours

The AI invents methods, doubles down when corrected, and burns tokens. There's no circuit breaker. So you become one.

📉

"Big Ball of Mud" by sprint 3

Without persisted architectural rules, every PR slowly drags your clean architecture back into the swamp. You feel it. You can't stop it.

This isn't a Cursor problem. It's a persistence problem.

The Persistence Protocol

Lock your architecture into the AI's long-term memory.

Agentic Architect isn't another prompt pack. It's a directory-level configuration system — 4 specialist .mdc rules + a stateful Learning Log — that loads only the right context for the file you're editing.

BEFORE

Generic prompts & chat-bot Cursor

  • Re-context every session
  • AI forgets last week's refactor
  • Suggests anti-patterns confidently
  • Loops on the same hallucination
  • Token bloat — entire rules dumped every prompt
  • Architecture decays sprint after sprint
AFTER

Cursor with Agentic Architect

  • Sessions start hydrated — log auto-loads
  • Knows every architectural decision you've made
  • Refuses patterns that violate your boundaries
  • Circuit breaker halts hallucination loops
  • Scoped loading — only relevant rules per file
  • Architecture compounds over time
What's Inside the Kit

Four specialist rules. One stateful brain.

Each rule is engineered for a specific architectural concern, loaded only when relevant — so the AI is always sharp and never overloaded.

arch-core.mdc Architecture

The Boundary Guardian

Enforces SOLID boundaries and prevents "Big Ball of Mud" suggestions. Stops the AI from crossing layer lines — no DbContext in controllers, no business logic in repositories, ever.

  • SOLID compliance audits on every suggestion
  • Layered architecture boundary enforcement
  • Anti-pattern early-warning system
dotnet-di.mdc .NET DI

The DI Auditor

A specialized auditor for constructor injections and service lifetimes. Catches Scoped → Singleton capture bugs before they ship. Knows IServiceCollection, Scrutor, Autofac patterns by heart.

  • Lifetime conflict detection
  • Constructor-injection best practices
  • Module registration discipline
bug-breaker.mdc Circuit Breaker

The Hallucination Killer

A circuit-breaker that stops the AI when it enters a hallucination loop. Detects repeated failed solutions, forces it to step back, re-read the file, and ask — instead of doubling down.

  • Loop-detection on failed attempts
  • Forced context re-read protocol
  • Token waste prevention
persistence.mdc ★ The Engine

The Project's Long-Term Memory

The engine that maintains your LEARNING_LOG.md — the persistent "brain" of your project. Every architectural decision, refactor reason, and "we tried that, don't do it again" lesson gets logged and re-hydrated automatically.

  • Auto-append architectural decisions (ADR-style)
  • Session-start hydration protocol
  • Cross-session continuity — true statefulness

Plus, you'll also get:

📘 Quickstart PDFFrom zero to hydrated in 60 seconds.
🧩 LEARNING_LOG templatePre-seeded for a typical .NET solution.
🛠 Daily Senior Rule UpdatesNew patterns dropped via the repo.
♾ Lifetime updatesFuture rules & protocol upgrades free.
How It Works

From zero to a stateful AI partner in three steps.

  1. 01

    Purchase & download

    Instant access via Gumroad. You get the full .cursor/rules/ folder and a pre-seeded LEARNING_LOG.md template.

  2. 02

    Drop into your project

    Copy .cursor/rules/ into your repo root. Cursor auto-detects the rules. No build step. No CLI. No config files to edit.

  3. 03

    Initialize the Log

    Run the included "hydrate" prompt once. The AI seeds your LEARNING_LOG.md from your codebase and starts tracking decisions automatically.

Why Senior Engineers Switch

This isn't theory. It's how serious teams use Cursor.

"I've burned hours every week fighting AI drift on a complex DDD codebase. The Learning Log alone paid for itself in the first afternoon. The DI auditor caught a Scoped-into-Singleton bug that would've shipped."
James M.Principal Engineer, FinTech (.NET 8 / DDD)
"The bug-breaker rule is genuinely novel. The AI used to spiral when it didn't know an answer — now it stops, re-reads the file, and asks me. That's the behavior I actually want from a senior pair-programmer."
Sara R.Tech Lead, Clean Architecture shop
"Finally — Cursor rules that respect token budgets. Scoped loading per directory means the relevant .mdc kicks in for that file, not a 2,000-token preamble on every prompt."

✅ This is for you if…

  • You're a Senior / Staff / Principal engineer on a real .NET codebase.
  • You use Cursor daily and feel the "context tax" pain.
  • You care about architecture, not just shipping features.
  • You want the AI to be a partner, not a fancy autocomplete.
  • You want a system you can commit to your repo and onboard your team to.

❌ This isn't for you if…

  • You're learning your first language. (Come back when you have a codebase to protect.)
  • You think "good enough" prompts are fine.
  • You don't use Cursor.
  • You don't write C#/.NET. (Rules are tuned for the .NET ecosystem.)
  • You'd rather pay a £30/mo SaaS than own your tooling.

Honest Answers

Frequently asked (and the objections we hear).

Isn't this just a few prompt files I could write myself?

You could — and we did, over hundreds of hours, across real production .NET codebases. The framework isn't the prompts; it's the directory-level loading strategy, the circuit-breaker pattern, and the Learning Log protocol that gives Cursor true statefulness. Writing it yourself is a weekend project. Maintaining it is a second job.

Will this work with Cursor's built-in rules feature?

Yes — that's exactly what it's built for. The .mdc files plug directly into Cursor's native rules system. We just use it with discipline.

Does it work for non-.NET languages?

The persistence.mdc engine and bug-breaker.mdc are language-agnostic. arch-core.mdc and dotnet-di.mdc are tuned for C#/.NET. If you're not in the .NET world, you'll get value from 2 of the 4 rules — your call whether £19.99 is worth that.

Is it a subscription?

No. One-time £19.99. Lifetime updates. MIT-licensed. We hate subscriptions as much as you do.

How is this different from generic "Cursor rules" repos on GitHub?

Most public rules are monolithic — a single rule dumped on every prompt, blowing your token budget. Agentic Architect uses scoped, directory-aware loading so only relevant rules activate for the file you're in. Plus, none of them solve persistence — the actual root cause of AI drift.

What if my team doesn't want to adopt it?

They don't have to. The rules live in .cursor/rules/ and the Learning Log is just a markdown file. Both can be in .gitignore or committed for the team — your call.

What if it doesn't work for me?

14-day no-questions refund. Email agenticstandardcontact@gmail.com. We'd rather refund you than have an unhappy senior engineer telling their network.

Why is it £19.99 and not £99?

Founder's pricing. It will go up. The countdown at the top is real — we raise the price each cohort to fund ongoing rule development.

You can keep paying the Context Tax.
Or you can stop, today.

Drop the .cursor/rules/ folder in. Hydrate the log. Watch your AI go from forgetful intern to stateful architectural partner — by tomorrow morning.
