springboot-migration
Migrates Spring Boot applications to Boot 4 with Java 25, including related Spring Modulith 2 and Testcontainers 2 upgrade work. Use when the task is a concrete upgrade, dependency transition, starter rename, test-annotation migration, or phased migration plan. Do not use for greenfield project creation or for isolated repository design questions.

Discovery
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.
This is an excellent skill description that clearly defines its scope, provides specific concrete actions, includes natural trigger terms users would use, and explicitly states both when to use and when NOT to use the skill. The description uses proper third-person voice and is concise while being comprehensive.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Migrates Spring Boot applications to Boot 4 with Java 25', 'Spring Modulith 2 and Testcontainers 2 upgrade work', 'dependency transition, starter rename, test-annotation migration, phased migration plan'. | 3 / 3 |
Completeness | Clearly answers both what (migrates Spring Boot apps with specific upgrade tasks) AND when ('Use when the task is a concrete upgrade...') with explicit triggers. Also includes helpful negative guidance ('Do not use for greenfield project creation'). | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms users would say: 'Spring Boot', 'Boot 4', 'Java 25', 'Spring Modulith 2', 'Testcontainers 2', 'upgrade', 'dependency transition', 'starter rename', 'test-annotation migration', 'migration plan'. | 3 / 3 |
Distinctiveness Conflict Risk | Very clear niche targeting Spring Boot 4/Java 25 migrations specifically. The explicit exclusions ('Do not use for greenfield project creation or for isolated repository design questions') further reduce conflict risk with other skills. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a high-quality skill that demonstrates excellent structure for a complex multi-phase migration workflow. It provides concrete tooling (scanner script), clear sequencing with validation checkpoints, and well-organized references to detailed guides. The content respects Claude's intelligence while providing the specific, actionable guidance needed for migration work.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient, avoiding explanations of concepts Claude already knows. Every section serves a clear purpose with no padding or unnecessary context about what Spring Boot or migrations are. | 3 / 3 |
Actionability | Provides concrete executable commands (the scanner script), specific file paths to reference guides, clear phase breakdowns with specific tasks, and a structured output format template. Copy-paste ready where applicable. | 3 / 3 |
Workflow Clarity | Excellent multi-step workflow with clear sequencing (Steps 1-5), explicit validation checkpoint in Phase 4, progress reporting requirements after each phase, and a defined order for mixed upgrades. Includes feedback loop guidance ('stop when failures appear'). | 3 / 3 |
Progressive Disclosure | Well-structured overview with clear one-level-deep references to four specific markdown files. The reference loading guide and table clearly signal when to load each document. Content is appropriately split between overview and detailed references. | 3 / 3 |
Total | 12 / 12 Passed |
