What it does

Structure software around the Dependency Rule: source code dependencies point inward from frameworks to use cases to entities. Use when the user mentions "architecture layers", "dependency rule", "ports and adapters (hexagonal)", "onion architecture", "screaming architecture", "where should business logic go", "decouple from the database", "swap the framework without a rewrite", or "keep business rules independent".

What this skill changes about the agent has not been set out here as a list. Its SKILL.md, shown below, says it in the author’s own words.

The skill itself

A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.

10# Clean Architecture Framework
11
12A disciplined approach to structuring software so that business rules remain independent of frameworks, databases, and delivery mechanisms. Apply these principles when designing system architecture, reviewing module boundaries, or advising on dependency management.
13
14## Core Principle
15
16**Source code dependencies must point inward — toward higher-level policies.** Nothing in an inner circle can know anything about an outer circle. This single rule produces systems that are testable and independent of frameworks, UI, database, and any external agency. Business rules are what matter; databases, web frameworks, and delivery mechanisms are details — when details depend on policies, you can defer decisions, swap implementations, and test business logic in isolation.
17
18## Scoring
19
20**Goal: 10/10.** Score one point for each of the seven Quick Diagnostic rows the architecture satisfies (0-7), then map to a 0-10 band: 6-7 satisfied = **9-10** (Dependency Rule holds, business logic is framework- and DB-independent); 4-5 = **6-8** (core is testable but some details leak inward); 2-3 = **3-5** (framework or persistence dictates structure); 0-1 = **0-2** (no boundaries — business rules live in controllers and ORM models). Report the score, the failed diagnostic rows, and the specific inversion needed to fix each.
21
22### 1. Dependency Rule and Concentric Circles
23
24**Core concept:** Organize the architecture as concentric circles — Entities (enterprise business rules) innermost, then Use Cases (application business rules), then Interface Adapters, with Frameworks and Drivers outermost. Source code dependencies always point inward.
25
26**Why it works:** When high-level policies don't depend on low-level details, you can swap the database, web framework, or API style without touching business logic — the system becomes resilient to the most volatile parts of the stack.

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

≈220
always loaded
The name and description, so the model knows the skill exists and when to reach for it.

13.6%
of a 200k window
Ten skills this size would not fit in the window together.
050k100k150k200k context window

27.2k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Heavy. Teams tend to install this one per project rather than globally, and load it only when the job comes up.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.

What it asks for
Writes filesnot declared
Network accessnot declared

This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

7 files, 108.7 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

  • SKILL.md16.4 kB
  • references/adapters-frameworks.md15.9 kB
  • references/boundaries.md18.3 kB
  • references/component-principles.md12.8 kB
  • references/dependency-rule.md13.6 kB
  • references/entities-use-cases.md14.8 kB
  • references/solid-principles.md16.9 kB
What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 7 files you can review in full before installing. The MIT licence covers the templates and examples as well as the instructions.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

# Clean Architecture Framework · 27.2k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/clean-architecture-framework/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/clean-architecture-framework" ] && { [ ! -e .claude/skills/clean-architecture-framework ] || { mv .claude/skills/clean-architecture-framework "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/clean-architecture-framework" .claude/skills/ && echo "Installed .claude/skills/clean-architecture-framework"
On Windows, or any OS with Node 20+
npx mcprush@latest skill add wondelai/clean-architecture-framework

Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/clean-architecture-framework/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/clean-architecture-framework/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/clean-architecture-framework" ] && { [ ! -e ~/.claude/skills/clean-architecture-framework ] || { mv ~/.claude/skills/clean-architecture-framework "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/clean-architecture-framework" ~/.claude/skills/ && echo "Installed ~/.claude/skills/clean-architecture-framework" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/clean-architecture-framework/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where. It appears as clean-architecture in Gemini CLI, Codex, Copilot and Grok (its own name); Claude Code lists it by the folder name, clean-architecture-framework.

Which clients pick it up on their own

A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.

Versions

v1.4.0 is what is on the shelf; no release here carries a date. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

v1.4.0
  • No earlier releases have been published to the marketplace.
Pinning

The install command always fetches the release that is current the day you run it — v1.4.0 today — and cannot ask for an earlier one. The copy on your disk does not change until you run it again.
