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 rmyndharis/antigravity-skills at 3eff4af253.

    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

The backend-security-coder skill empowers AI agents to generate, audit, and harden server-side code against common vulnerabilities. It focuses on implementing secure coding practices directly within application logic to protect data integrity and system availability.

When to use it

  • Refactoring legacy codebases to comply with OWASP Top 10 security standards.
  • Generating secure API endpoints that validate inputs and sanitize outputs automatically.
  • Auditing existing backend functions for injection flaws, broken authentication, or insecure configurations.
  • Creating automated scripts to patch identified security gaps in production-ready environments.

Key capabilities

  • Identifies and mitigates common backend vulnerabilities like SQL injection and XSS.
  • Generates secure authentication mechanisms and session management logic.
  • Implements input validation and output encoding strategies.
  • Produces hardened configuration files for web servers and application frameworks.

Example prompts

  • "Review this Node.js Express route and suggest fixes to prevent SQL injection attacks."
  • "Generate a Python Flask endpoint that securely handles user authentication with password hashing."
  • "Audit the following backend code snippet for insecure direct object references (IDOR) and provide a corrected version."

Tips & gotchas

Ensure you provide complete context, including the specific programming language and framework being used, to get accurate security implementations. While this skill excels at generating secure patterns, it should be part of a broader DevSecOps strategy that includes regular penetration testing and dependency scanning.
