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 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.

  • Declares what it does: failed

    No SKILL.md was found in the skill's directory.

    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 sickn33/antigravity-awesome-skills at 5a4cdd9df8.

    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 secure server-side code, focusing on vulnerability prevention and robust architecture. It assists developers in writing Python, JavaScript, or Go backends that integrate essential security protocols like authentication and encryption from the ground up.

When to use it

  • Generating API endpoints with built-in rate limiting and input sanitization to prevent injection attacks.
  • Creating database connection handlers that enforce parameterized queries and least-privilege access controls.
  • Developing serverless functions or microservices that include secure session management and token validation logic.
  • Refactoring legacy backend code to address common flaws such as hardcoded secrets or missing HTTPS enforcement.

Key capabilities

  • Writes production-ready backend code in multiple languages including Python, Node.js, and Go.
  • Implements industry-standard security patterns like OAuth2, JWT handling, and CORS configuration.
  • Generates code structures that automatically validate user inputs against known attack vectors.
  • Produces modular functions specifically designed to minimize the attack surface of web applications.

Example prompts

  • "Create a secure Python Flask API endpoint for user registration that hashes passwords using bcrypt and validates email formats."
  • "Write a Node.js middleware function to enforce strict CORS policies and sanitize all incoming JSON payloads."
  • "Generate a Go service for handling JWT authentication with proper expiration checks and refresh token rotation logic."

Tips & gotchas

This skill is designed for generating code, not for performing live penetration testing or scanning existing infrastructure. Ensure you review the generated code against your specific compliance requirements before deploying it to production environments.
