This skill no longer installs under the name modern-java-backend-playbook. flaviodotcom/quarkus-java-backend-playbook has no skill named "modern-java-backend-playbook" any more. It was renamed, moved or deleted upstream.

We check each listing against its upstream repository with the rules the skills CLI uses, last on 2026-09-28. We don't show a command we know will fail.

Taken from the source listing. We haven't verified who controls this account.

Install target

Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned flaviodotcom/modern-java-backend-playbook at e7b116c39f.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill enables AI agents to generate and understand code related to modern Java backend development. It can assist in creating REST APIs, implementing data persistence using frameworks like Spring Boot, and generating boilerplate code for common backend tasks. The playbook focuses on utilizing contemporary Java practices and technologies.

When to use it

  • Generating initial project structures for new Java-based microservices.
  • Creating basic CRUD (Create, Read, Update, Delete) operations for a database entity.
  • Developing REST API endpoints with request handling and response formatting.
  • Automating the creation of unit tests using frameworks like JUnit or Mockito.
  • Generating configuration files for Spring Boot applications.

Key capabilities

  • REST API generation
  • Data persistence implementation (Spring Boot)
  • Boilerplate code generation
  • Unit test generation (JUnit, Mockito)
  • Configuration file creation

Example prompts

  • "Generate a Spring Boot REST controller for managing 'products' with endpoints for create, read, update, and delete."
  • "Create a JUnit test case for the UserService class that verifies user authentication."
  • "Show me how to configure a database connection in a Spring Boot application using YAML."

Tips & gotchas

This skill assumes some familiarity with Java and backend development concepts. While it can generate code, understanding the underlying principles is crucial for debugging and customization.
