Conciseness

The body is dense and assumes competence: real commands, a prefix table, an anti-patterns table, and no primers on what databases or migrations are. Minor over-explanation keeps it below a 5: the meta 'Follow Steps 1 - 7 below in order; each numbered step is the single source' sentence and the narrative 'Safety property' paragraph that restates `outOfOrder` semantics already covered in the config comments.

Actionability

Mostly executable: `docker run --rm -e FLYWAY_PASSWORD flyway/flyway ... migrate`, `brew install flyway`, a real `flyway.conf` properties block, and a worked example with actual SQL (`CREATE INDEX idx_users_email ON users(email);`). The gap is the Maven path - the install snippet is a stub comment ('# add to pom.xml under <build><plugins>') with no actual plugin XML, and the Testcontainers pattern is deferred to the reference file.

Workflow Clarity

Steps 1-7 are clearly sequenced, the daily loop 'info -> migrate -> validate' is stated, and validation for destructive operations is explicit: the failed-migration path routes to `flyway repair` instead of editing applied files, the worked example shows `validate` catching a checksum mismatch and recovering with a `V3` migration, and `flyway clean` is guarded by the `cleanDisabled=true` production rule plus an anti-patterns row. This satisfies the destructive-operation feedback-loop requirement rather than triggering the cap at 3.

Progressive Disclosure

One reference file (references/commands.md) is one level deep, referenced inline twice with purpose stated ('Full command reference (baseline, undo, clean, and the rest)' and 'The full GitHub Actions job ... are in references/commands.md') and listed again in the References section; the file exists and delivers the promised command table and CI job. Minor gaps: the 'How to use' section is only a pointer sentence, and the trailing sister-tool list (`liquibase-migrations`, `atlas-migrations`, `sqlmesh-migrations`) names files that are not part of this bundle and give no navigation guidance.

Specificity

The description lists multiple concrete actions with real artifacts: 'Authors and runs Flyway database migrations - versioned (`V1__add_users.sql`), repeatable (`R__refresh_views.sql`), and undo (`U1__remove_users.sql`)', 'runs `flyway migrate` / `info` / `validate` / `clean` / `baseline` / `repair`', 'tracks state in the `flyway_schema_history` table'. Coverage is comprehensive with no notable gap, matching the 5 anchor.

Completeness

Both halves are explicit: a detailed 'what' (author, run, track, 50+ databases, integrations) followed by 'Use when the user works with Flyway-managed schemas, asks about migration ordering, or needs CI gates on schema changes' with concrete trigger phrases. This mirrors the 5 anchor example structure exactly.

Trigger Term Quality

Natural user terms are comprehensively covered: 'Flyway', 'database migrations', 'migration ordering', 'schema changes', 'CI gates', plus file naming patterns (`V1__...sql`), database names, and integration names (Maven, Gradle, CLI, Docker). A user needing this skill would naturally say any of these; nothing obvious is missing.

Distinctiveness Conflict Risk

Flyway is a specific named tool with distinct triggers (Flyway commands, file prefixes, `flyway_schema_history`), so overlap risk with generic SQL or migration skills is minimal. Sister tools like Liquibase are clearly out of scope.
