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.

Content

85%

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

A well-structured, concise overview that defers detail to five genuine reference files and sequences its workflow with real validation checkpoints. The only gap is the absence of inline executable pattern examples, leaving actionability just below top.

Suggestions

Add one small inline Java example (e.g. a minimal Strategy or Repository snippet) to lift actionability from advice to copy-paste-ready.

Show a concrete 'when-not-to-use' trade-off example inline so the TRADE-OFFS REQUIRED constraint is operationalized rather than only stated.

DimensionReasoningScore

Conciseness

The body is lean: it does not re-explain what design patterns or Kafka are, and every section (scope, constraints, workflow, references) earns its place. It respects Claude's competence and stays well within token budget.

3 / 3

Actionability

Concrete guidance exists — real build commands ('./mvnw compile', 'mvn clean verify') and exact reference filenames — but no inline executable code or worked Java/pattern examples; guidance is actionable for an instruction skill yet stops short of copy-paste-ready material.

2 / 3

Workflow Clarity

A clear five-step sequence with explicit validation ('Validate the outcome', 'Run the project build for code changes') and build-safety checkpoints (compile before refactoring, verify after changes), matching the anchor for sequenced steps with explicit validation.

3 / 3

Progressive Disclosure

SKILL.md is an overview pointing to five real, one-level-deep reference files (all present in references/), signaled clearly in both the Workflow and Reference sections; no nested/deep references.

Description

100%

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, problem-led description that states concrete capabilities across five sub-domains and gives explicit natural-language triggers. It cleanly answers both 'what' and 'when' with no notable fluff.

DimensionReasoningScore

Specificity

Lists multiple concrete actions across five named domains — 'select, review, or implement' plus 'Apply Java design patterns; Review REST API patterns; Design Kafka event-driven patterns; Improve database persistence patterns; Add resilient integration patterns' — matching the 'lists multiple specific concrete actions' anchor.

3 / 3

Completeness

Explicitly answers both what ('select, review, or implement Java design and integration patterns') and when ('Use when you need to...', 'This should trigger for requests such as...'), satisfying the explicit-trigger anchor for a 3.

3 / 3

Trigger Term Quality

Trigger phrases like 'Apply Java design patterns', 'Review REST API patterns', 'Design Kafka event-driven patterns' are natural things a user would say, giving good coverage rather than jargon.

3 / 3

Distinctiveness Conflict Risk

The Java design/integration-pattern niche with domain-specific triggers (Kafka, REST, persistence, integration) is distinct and unlikely to fire for unrelated skills; scoped to the cursor-rules-java project.
