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 herdiansah/antigravity-skills-master at f642a05f9c.

    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 helps you generate secure backend code. It can identify potential vulnerabilities in existing code and suggest fixes, as well as create new code with security best practices already implemented. The skill focuses on improving the overall robustness of your server-side applications against common attacks.

When to use it

  • You need to review a codebase for potential security flaws before deployment.
  • You’re building a new backend and want to ensure secure coding from the start.
  • You're refactoring existing code to improve its security posture.
  • You require assistance in implementing specific security measures like input validation or authentication protocols.

Key capabilities

  • Vulnerability identification
  • Secure code generation
  • Security best practices implementation
  • Code review and suggestions for improvement

Example prompts

  • "Review this Python code snippet for SQL injection vulnerabilities: [code]"
  • "Generate a secure user authentication endpoint in Node.js."
  • "Suggest improvements to this Java function to prevent cross-site scripting (XSS) attacks: [code]"

Tips & gotchas

The skill’s effectiveness depends on the quality and clarity of the provided code. Providing context about the application's purpose can also help it generate more relevant security suggestions.
