Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00079 | $0.03386 |
| Opus 5.5 | $0.00032 | $0.01354 |
| Sonnet 5.5 | $0.00016 | $0.00677 |
| Haiku 4.5 | $0.00008 | $0.00339 |
Grade A, and why
clean-architecture 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 1mo 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.

Clean Architecture, Hexagonal Architecture & DDD for Spring Boot
Overview
This skill provides comprehensive guidance for implementing Clean Architecture, Hexagonal Architecture (Ports & Adapters), and Domain-Driven Design tactical patterns in Java 21+ Spring Boot 3.5+ applications. It ensures clear separation of concerns, framework-independent domain logic, and highly testable codebases through proper layering and dependency management.
When to Use
- Architecting new Spring Boot applications with clear separation of concerns
- Refactoring tightly coupled code into testable, layered architectures
- Implementing domain logic independent of frameworks and infrastructure
- Designing ports and adapters for swappable implementations
- Applying Domain-Driven Design tactical patterns (entities, value objects, aggregates)
- Creating testable business logic without Spring context dependencies
Instructions
1. Understand the Core Concepts
Clean Architecture Layers (Dependency Rule)
Dependencies flow inward. Inner layers know nothing about outer layers.
| Layer | Responsibility | Spring Boot Equivalent |
|---|---|---|
| Domain | Entities, value objects, domain events, repository interfaces | domain/ - no Spring annotations |
| Application | Use cases, application services, DTOs, ports | application/ - @Service, @Transactional |
| Infrastructure | Frameworks, database, external APIs | infrastructure/ - @Repository, @Entity |
| Adapter | Controllers, presenters, external gateways | adapter/ - @RestController |
Hexagonal Architecture (Ports & Adapters)
- Domain Core: Pure Java business logic, no framework dependencies
- Ports: Interfaces defining contracts (driven and driving)
- Adapters: Concrete implementations (JPA, REST, messaging)
Domain-Driven Design Tactical Patterns
- Entities: Objects with identity and lifecycle (e.g.,
Order,Customer) - Value Objects: Immutable, defined by attributes (e.g.,
Money,Email) - Aggregates: Consistency boundary with root entity
- Domain Events: Capture significant business occurrences
- Repositories: Persistence abstraction, implemented in infrastructure
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

clean-architecture is a skill published in the GitHub repository giuseppe-trisciuoglio/developer-kit (360 stars, last pushed 1mo ago), licensed MIT. It adds 79 tokens to every session and 3,386 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-10.
