123-java-design-patterns

Use when you need to select, review, or implement Java design and integration patterns — including classic Java design patterns, REST API patterns, Kafka and event-driven patterns, database and persistence patterns, and cross-cutting integration patterns. This should trigger for requests such as Apply Java design patterns; Review REST API patterns; Design Kafka event-driven patterns; Improve database persistence patterns; Add resilient integration patterns.

Quality

Content

78%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-organized instruction skill with a clear problem-led workflow, concrete build commands, and clean progressive disclosure to five real reference files. The main gaps are mild redundancy with the description and abstract pattern-selection guidance that defers concreteness to the references.

DimensionReasoningScore

Conciseness

The body is efficient with no padding of concepts Claude already knows, but the 'What is covered in this Skill?' and 'When to use this skill' sections largely duplicate content already present in the frontmatter description, which could be trimmed.

4 / 5

Actionability

Provides concrete commands ('./mvnw compile', 'mvn clean verify'), explicit reference file paths, and a sequenced workflow, but the core pattern-selection guidance ('Recommend the smallest useful pattern', 'Show how it changes responsibilities') stays abstract since concrete examples live in the references.

4 / 5

Workflow Clarity

A clear five-step sequence with an explicit validation step ('Validate the outcome' / run the build) and BUILD SAFETY constraints that run compile before and verify after, but the error-recovery feedback loop (validate -> fix -> retry) is implied rather than spelled out, so it is short of a 5.

4 / 5

Progressive Disclosure

A concise overview body that points to five one-level-deep reference files via clearly signaled markdown links, all verified to exist, with content appropriately split and easy to navigate.

Description

83%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, well-structured description that clearly states capabilities across five pattern families and provides explicit, natural trigger phrases for when to use it. The main weakness is that the action verbs (select/review/implement) are generic and the trigger phrasing is somewhat repetitive rather than offering synonyms.

DimensionReasoningScore

Specificity

Names the domain and five concrete pattern families (classic Java, REST API, Kafka/event-driven, database/persistence, cross-cutting) plus three actions (select, review, implement), but the action verbs are generic rather than concrete operations, leaving minor coverage gaps short of a 5.

4 / 5

Completeness

Explicitly answers both what ('select, review, or implement Java design and integration patterns' across five families) and when ('Use when you need to...' plus 'This should trigger for requests such as...') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Includes natural trigger phrases users would say ('Apply Java design patterns', 'Review REST API patterns', 'Design Kafka event-driven patterns') with good coverage across families, but the triggers are formulaic and omit synonyms, so it falls short of comprehensive.

4 / 5

Distinctiveness Conflict Risk

Clear niche focused on Java design and integration patterns across five distinct families with specific triggers, but it could still overlap with general Java code-review or architecture skills, so it is not a clean 5.
