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 failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 2 hosts that are neither well-known infrastructure nor declared in the skill's frontmatter: auth.myapp.com, jwt.io.

    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.

  • 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 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 giuseppe-trisciuoglio/developer-kit at fe73fb33a0.

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

About this skill

What it does

This skill enables AI agents to implement JSON Web Token (JWT) authentication in Spring Boot applications. It provides the necessary code and configuration for securing REST APIs using JWT, including token generation, validation, and integration with Spring Security.

When to use it

  • You need to secure a Spring Boot API with token-based authentication.
  • You are building a microservices architecture that requires stateless authentication.
  • Your application needs to support user login and session management without server-side sessions.

Key capabilities

  • JWT token generation upon successful user authentication
  • Token validation for incoming requests
  • Integration with Spring Security filters
  • Custom user details service implementation
  • Configuration of security rules for protected endpoints

Example prompts

  • "Implement JWT-based authentication in a Spring Boot REST API."
  • "Add token validation to secure the /api/users endpoint."
  • "Generate a JWT token after a user logs in successfully."

Tips & gotchas

  • Ensure that your application has proper dependencies for Spring Security and JWT libraries.
  • Customize token expiration times and signing keys according to your security requirements.
