42%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The skill is well organized and its code is illustrative, but it spends substantial tokens teaching concepts Claude already knows and never gives an operative sequence for applying the patterns. The code examples also fall short of executable due to undefined types and one stubbed adapter.
Suggestions
Replace the 'Core Concepts' section with a one-line-per-pattern decision table (when to choose Clean vs Hexagonal vs DDD); Claude already knows these definitions, so the ~40 lines re-teach known material.
Make code examples self-contained and runnable: define CreateUserResponse, declare find_by_email on IUserRepository, complete the StripePaymentAdapter stub, and either define or trim the undefined supporting types in the Hexagonal/DDD snippets.
Add a stepwise application workflow (e.g., assess coupling boundaries → define ports → migrate logic inward → verify domain tests pass without infrastructure) and move the per-pattern code deep dives into references/ files to shorten the main body.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The ~40-line 'Core Concepts' section re-explains Clean Architecture layers, Hexagonal components, and DDD strategic/tactical patterns — textbook knowledge Claude already has — and the long illustrative code blocks add further bulk, matching 'noticeably verbose; several unnecessary explanations'. | 2 / 5 |
Actionability | The directory structure and use-case flow are concrete, but the code is not executable: CreateUserResponse is never defined, find_by_email is called but absent from IUserRepository, StripePaymentAdapter's body is just '# Implementation', and the Hex/DDD snippets depend entirely on undefined types. | 3 / 5 |
Workflow Clarity | There is no multi-step process at all — no sequence for choosing among the three patterns or applying one to an existing codebase — so the content describes rather than sequences, with no checkpoints or error-recovery guidance. | 3 / 5 |
Progressive Disclosure | Section headers are well organized, but ~295 lines are entirely inline with no references or bundle files, and the three per-pattern deep-dive code sections are content that clearly belongs in separate reference files. | 3 / 5 |
