513-frameworks-micronaut-db-migrations-flyway
This Claude Code skill guides configuration and implementation of Flyway database migrations in Micronaut applications, covering micronaut-flyway dependency setup, SQL migration scripts in src/main/resources/db/migration, and datasource-specific configuration. Use it when adding new migrations, reviewing existing migration chains, configuring Flyway with JDBC or Micronaut Data, or ensuring migrations integrate properly with Testcontainers-based tests.

# Micronaut — Database migrations (Flyway) Apply Flyway migration guidelines for Micronaut. **What is covered in this Skill?** - `micronaut-flyway` with JDBC/Hikari and database drivers - Versioned SQL under `src/main/resources/db/migration` - `flyway.datasources.*` (per-datasource) configuration in YAML/properties - Tests with Testcontainers and real migration chains - Coordination with `@511-frameworks-micronaut-jdbc` and `@512-frameworks-micronaut-data` **Scope:** Apply recommendations based on the reference rules and good/bad examples. ## Constraints Before applying Flyway or SQL changes, ensure the project compiles. After improvements, run full verification. - **MANDATORY**: Run `./mvnw compile` or `mvn compile` before applying any change - **SAFETY**: If compilation fails, stop immediately - **VERIFY**: Run `./mvnw clean verify` or `mvn clean verify` after applying improvements - **BEFORE APPLYING**: Read the reference for detailed rules and good/bad patterns - **EDGE CASE**: If the user goal is ambiguous, stop and ask a clarifying question before editing files or running project-wide commands - **EDGE CASE**: If required context, files, credentials, or tools are missing, report the blocker explicitly and ask whether to proceed with setup or fallback guidance - **EDGE CASE**: If requested changes conflict with project constraints or safety boundaries, explain the conflict and ask for user confirmation on the preferred trade-off ## When to use this skill - Add or review Flyway migrations in a Micronaut project - Configure micronaut-flyway or db/migration layout ## Workflow 1. **Read reference and assess project context** Read `references/513-frameworks-micronaut-db-migrations-flyway.md` and inspect the current project setup before proposing changes. 2. **Gather scope and decide target improvements** Identify requested outcomes, constraints, and the minimum safe set of changes to apply. 3. **Apply framework-aligned changes** Implement or refactor configuration/code following the reference patterns and project conventions. 4. **Run verification and report results** Execute appropriate build/tests and summarize what changed, what was verified, and any follow-up actions. ## Reference For detailed guidance, examples, and constraints, see [references/513-frameworks-micronaut-db-migrations-flyway.md](references/513-frameworks-micronaut-db-migrations-flyway.md).
Use when you need to generate a checklist document with Java system prompts, following the embedded template exactly and producing INVENTORY-SKILLS-JAVA.md in the project root. This should trigger for requests such as Create Java system prompts checklist; Generate INVENTORY-SKILLS-JAVA.md; Use @001-skills-inventory. Part of cursor-rules-java project
Use when you need to generate a checklist document with embedded agents inventory, following the embedded template exactly and producing INVENTORY-AGENTS-JAVA.md in the project root. This should trigger for requests such as Create embedded agents inventory checklist; Generate INVENTORY-AGENTS-JAVA.md; Use @002-agents-inventory. Part of cursor-rules-java project
Use when you need to install the embedded robot agents into either .cursor/agents or .claude/agents, selecting the destination interactively and copying the embedded agent definitions from project assets. This should trigger for requests such as Install embedded agents; Bootstrap .cursor/agents; Bootstrap .claude/agents; Copy robot agents. Part of cursor-rules-java project
Guides the creation of agile epics with comprehensive definition including business value, success criteria, and breakdown into user stories. Use when the user wants to create an agile epic, define large bodies of work, break down features into user stories, or document strategic initiatives. This should trigger for requests such as Create an agile epic; Write an epic; I need to create an epic; Define an epic; Epic definition. Part of cursor-rules-java project
Guides the creation of detailed agile feature documentation from an existing epic. Use when the user wants to split an epic into feature files, derive features with scope and acceptance criteria, or plan feature documentation for stakeholders or engineering. This should trigger for requests such as Create features from an epic; Split epic into features; Feature files from epic; Derive features from epic. Part of cursor-rules-java project
Guides the creation of agile user stories and Gherkin feature files. Use when the user wants to create a user story, write acceptance criteria, define Gherkin scenarios, or author BDD feature files. This should trigger for requests such as Create a user story; Write a user story; I need to write a user story. Part of cursor-rules-java project
Use when you need to generate Architecture Decision Records (ADRs) for a Java project through an interactive, conversational process that systematically gathers context, stakeholders, options, and outcomes to produce well-structured ADR documents. This should trigger for requests such as Generate ADR; Create Architecture Decision Record; Document architecture decision; Architecture Decision Record for Java. Part of cursor-rules-java project
Facilitates conversational discovery to create Architectural Decision Records (ADRs) for functional requirements covering CLI, REST/HTTP APIs, or both. Use when the user wants to document command-line or HTTP service architecture, capture functional requirements, create ADRs for CLI or API projects, or design interfaces with documented decisions. This should trigger for requests such as Create ADR for functional requirements; Document functional requirements; Capture functional requirements; Generate functional requirements in an ADR.
