111-java-maven-dependencies
This Claude Code skill guides users through adding Maven dependencies that enhance Java code quality, including nullness annotations via JSpecify, static analysis through Error Prone and NullAway, functional programming with VAVR, and architecture testing using ArchUnit. Use it when you need to evaluate and selectively add dependencies to improve code safety and maintainability while ensuring project validity through validation checks and a consultative question-driven approach.

# Add Maven dependencies for improved code quality Add essential Maven dependencies that enhance code quality and safety through a consultative, question-driven approach. **This is an interactive SKILL**. **What is covered in this Skill?** - JSpecify: (nullness annotations, `provided` scope) - Error Prone + NullAway: (enhanced static analysis with compile-time null checking) - VAVR: (functional programming with Try/Either and immutable collections) - ArchUnit: (architecture rule enforcement, `test` scope) ## Constraints Before adding Maven dependencies, ensure the project is in a valid state. Use a consultative, question-driven flow that adds only what the user selects. - **MANDATORY**: Run `./mvnw validate` or `mvn validate` before any changes - **SAFETY**: If validation fails, stop and ask the user to fix issues—do not proceed until resolved - **BEFORE ASKING QUESTIONS**: Read the reference to use the exact wording and options from the template. Ask questions one-by-one in strict order (JSpecify → Enhanced Compiler Analysis (conditional) → VAVR → ArchUnit) and add only what the user selects. Use consultative language, present trade-offs, and wait for user responses before implementing ## When to use this skill - Add Maven dependencies - Add JSpecify nullness dependencies - Add Error Prone NullAway dependencies - Add VAVR functional dependencies - Add ArchUnit architecture testing dependencies ## Workflow 1. **Validate project before changes** Run `./mvnw validate` or `mvn validate` and stop if validation fails. 2. **Read dependency reference and ask guided questions** Read `references/111-java-maven-dependencies.md` and ask one-by-one in strict order: JSpecify, conditional Enhanced Compiler Analysis, VAVR, and ArchUnit. 3. **Add only selected dependencies** Implement only the dependencies and scopes chosen by the user, preserving existing pom.xml structure. 4. **Report trade-offs and next checks** Summarize what was added, why, and any recommended follow-up validations or tooling alignment. ## Reference For detailed guidance, examples, and constraints, see [references/111-java-maven-dependencies.md](references/111-java-maven-dependencies.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.
