Conciseness

The body duplicates the frontmatter description verbatim in the 'When to use this skill' section, and three generic 'EDGE CASE' bullets ('If the user goal is ambiguous, stop and ask a clarifying question...') restate default Claude behavior Claude already knows. Not level 2 because the core content is terse with no concept explanations; not level 4 because the duplication and boilerplate are more than minor trimmable instances.

Actionability

Concrete commands are present ('Run ./mvnw compile or mvn compile', 'Run ./mvnw clean verify or mvn clean verify') and exact reference file paths are named, but workflow steps 2–4 stay high-level ('Implement or refactor configuration/code following the reference patterns'). Not level 5 because no inline config or migration example covers the common case; not level 3 because the commands and file pointers are executable and specific.

Workflow Clarity

The 4-step workflow (read references → gather scope → apply → verify and report) is clearly sequenced, and the Constraints section supplies explicit checkpoints: mandatory compile before changes, stop immediately on failure, full clean verify after. Not level 5 because there is no explicit fix-and-re-verify loop if verification fails — important for database operations.

Progressive Disclosure

The body is a clean overview: a coverage list, constraints, and a workflow that points to three real, existing reference files (main, antipatterns, parallel-change), each linked in the Reference section. All three bundle files verified on disk, one level deep with no nested references. This matches the level-5 anchor.

Specificity

The description lists multiple concrete actions — 'add or review Flyway database migrations in a Quarkus application — quarkus-flyway extension, db/migration scripts, quarkus.flyway.* configuration, migrate-at-start' plus six distinct task types (configure layout, add versioned SQL, review ordering, configure clean/migrate/baselines). Coverage of the skill's capability space is comprehensive; not level 4 because there are no minor gaps — actions, artifacts, and config surface are all named.

Completeness

Explicitly answers both questions: the 'what' ('add or review Flyway database migrations in a Quarkus application — quarkus-flyway extension, db/migration scripts, quarkus.flyway.* configuration') and the 'when' via both 'Use when you need to...' and an explicit trigger list ('This should trigger for requests such as...'). This matches the level-5 anchor exactly.

Trigger Term Quality

Strong natural phrasing users would actually say ('Add or review Flyway migrations in a Quarkus project', 'Configure quarkus-flyway or db/migration layout', 'Review Quarkus database migration ordering'), plus config keys like migrate-at-start. Falls short of level 5 because common synonyms such as 'schema migrations', 'database evolution', or '.sql' file extensions are absent.

Distinctiveness Conflict Risk

The Quarkus+Flyway niche is very narrow and every trigger phrase is Flyway-migration-specific, so it will not fire for generic Quarkus work. The mention of 'alignment with JDBC or Panache' defines coordination boundaries with sibling skills rather than claiming their scope, keeping conflict risk minimal.
