architecture-advisor

architecture-advisor is a skill for Claude Code, Codex from codewithmukesh/dotnet-claude-kit. It costs 103 tokens per session (2,477 once invoked), scanned A, original, MIT.

A question-based guide for choosing an architecture for .NET applications. Architecture is the way an application organizes its code and responsibilities; the guide compares Vertical Slice, Clean Architecture, domain-driven design with Clean Architecture, and Modular Monolith approaches.

In plain words
What is it for?
Use it before selecting a .NET application architecture, when comparing the four supported patterns, or when documenting why one structure fits a project.
Why use it?
It helps teams match the amount of structure to their domain complexity, team size, system lifetime, compliance needs, and integrations. It avoids recommending an unnecessarily complicated design without first gathering project context.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

architecture-advisor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Architecture Advisor

Core Principles

  1. Ask before recommending — Never prescribe an architecture without understanding the project. Run the questionnaire first to gather context about domain, team, lifetime, and constraints.
  2. Right-size the architecture — The best architecture is the simplest one that handles the project's actual complexity. CRUD apps do not need DDD. Startups do not need Clean Architecture. Match complexity to real requirements, not aspirations.
  3. Architecture is not permanent — Every architecture has an evolution path. Start simple and add structure when complexity demands it. Document the decision so the team knows when to evolve.
  4. Four supported architectures — dotnet-claude-kit provides first-class patterns for Vertical Slice Architecture (VSA), Clean Architecture (CA), DDD + Clean Architecture, and Modular Monolith. Each has specific strengths and trade-offs.

The Architecture Questionnaire

Before recommending an architecture, ask questions across these 6 categories. Not every question applies to every project — skip irrelevant ones.

Category 1: Domain Complexity

# Question Low Signal High Signal
1 How many distinct business entities does the system manage? < 10 entities 20+ entities with relationships
2 Do business rules involve multiple entities interacting? Rules are per-entity CRUD Complex invariants across entity groups
3 Are there business workflows with multiple steps? Simple request → response Sagas, approval chains, state machines
4 Do domain experts use specialized vocabulary? Generic terms (create, update) Ubiquitous language (underwrite, adjudicate)

Category 2: Team & Organization

# Question Low Signal High Signal
5 How large is the development team? 1-3 developers 8+ developers, multiple teams
6 Do different teams own different parts of the system? Single team owns everything Teams aligned to business domains
7 What is the team's experience level with .NET? Junior or mixed Senior, experienced with patterns

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

architecture-advisor is a skill published in the GitHub repository codewithmukesh/dotnet-claude-kit (697 stars, last pushed 28d ago), licensed MIT. It adds 103 tokens to every session and 2,477 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
