14%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill reads more like a textbook summary of architecture patterns than actionable guidance for Claude. It extensively explains concepts Claude already knows (Clean Architecture layers, DDD building blocks, hexagonal architecture), resulting in poor token efficiency. The code examples are the strongest element but suffer from incomplete definitions and missing imports, while the complete absence of a workflow or decision-making process means Claude gets no guidance on *how* to apply these patterns in practice.
Suggestions
Remove all conceptual explanations (Core Concepts section, Best Practices, Common Pitfalls) that Claude already knows, and focus exclusively on project-specific conventions, decision criteria, or non-obvious implementation details.
Add a concrete workflow: e.g., 'When asked to architect a new service: 1. Identify bounded contexts → 2. Define ports/interfaces → 3. Implement domain entities → 4. Add adapters → 5. Verify dependency direction with import analysis'.
Fix incomplete code examples: define CreateUserResponse, add find_by_email to IUserRepository interface, define the Port interfaces used in the hexagonal example, and implement _to_entity.
Split content into separate referenced files per pattern (e.g., CLEAN_ARCHITECTURE.md, HEXAGONAL.md, DDD.md) with SKILL.md serving as a concise overview with decision criteria for choosing between them.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extensively explains concepts Claude already knows well—Clean Architecture layers, DDD tactical patterns, hexagonal architecture benefits. The 'Core Concepts' section is essentially a textbook summary that adds no novel information. The 'When to Use This Skill' list and 'Best Practices' / 'Common Pitfalls' sections are generic knowledge Claude possesses. The entire document could be reduced to the code examples with minimal framing. | 1 / 3 |
Actionability | The code examples are fairly concrete and near-executable (Python dataclasses, repository pattern, use cases), but several have incomplete references (e.g., CreateUserResponse is used but never defined, find_by_email is called but not in the interface, OrderRepositoryPort/PaymentGatewayPort/NotificationPort are referenced but undefined, _to_entity is called but not shown). The Stripe adapter has a comment placeholder instead of implementation. These gaps prevent copy-paste readiness. | 2 / 3 |
Workflow Clarity | There is no workflow or sequenced process for actually implementing these patterns. The skill describes what the patterns are and shows code snippets, but never guides through a multi-step process of architecting or refactoring a system. There are no validation checkpoints, no decision trees for choosing between patterns, and no feedback loops for verifying the architecture is correctly implemented. | 1 / 3 |
Progressive Disclosure | The content is a monolithic wall of text with no references to external files and no layered structure. All three architecture patterns plus DDD concepts, best practices, and pitfalls are dumped into a single file with no navigation aids or separation of concerns. For a skill of this complexity, content should be split across referenced files (e.g., separate files per pattern). | 1 / 3 |
