Java Documentation Generator with modular step-based configuration

Generate comprehensive Java project documentation through a modular, step-based interactive process that covers README.md, package-info.java, and Javadoc. This is an interactive SKILL.

What is covered in this Skill?

• README.md generation for single-module and multi-module Maven projects
• package-info.java creation with basic/detailed/minimal documentation levels
• Javadoc enhancement: comprehensive @param/@return/@throws tags
• File handling strategies: overwrite/add/backup/skip
• Final documentation validation with ./mvnw clean compile and ./mvnw javadoc:javadoc

Constraints

Before applying any documentation generation, ensure the project validates. If validation fails, stop immediately — do not proceed until all validation errors are resolved.

• MANDATORY: Run ./mvnw validate or mvn validate before applying any documentation generation
• SAFETY: If validation fails, stop immediately — do not proceed until all validation errors are resolved
• BEFORE APPLYING: Read the reference for detailed good/bad examples, constraints, and safeguards for each documentation generation pattern
• EDGE CASE: If request scope is ambiguous, stop and ask a clarifying question before applying changes
• EDGE CASE: If required inputs, files, or tooling are missing, report what is missing and ask whether to proceed with setup guidance

When to use this skill

• Improve the code with documentation
• Apply documentation
• Refactor the code with documentation

Workflow

1. Validate project before documentation changes

Run ./mvnw validate or mvn validate and stop immediately if validation fails.

1. Read documentation reference and gather scope

Read references/170-java-documentation.md and identify required outputs (README, package-info, Javadoc enhancements).

1. Generate selected documentation artifacts

Create or update documentation using the selected file-handling strategy (overwrite/add/backup/skip).

1. Run documentation validation checks

Execute ./mvnw clean compile and ./mvnw javadoc:javadoc (or equivalent) to validate generated docs.
