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 nicolasestrem/antigravity-gemini-skills at 5816ff4d9f.

    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 function as full-stack developers, capable of handling both front-end and back-end development tasks. It can generate code for web applications, assist in debugging existing projects, and provide guidance on architectural decisions. The agent is designed to streamline the software development process by automating repetitive coding tasks and offering expert advice.

When to use it

  • Rapid Prototyping: Quickly build a basic web application or landing page from scratch.
  • Debugging Assistance: Troubleshoot errors in existing codebases, identifying potential issues and suggesting fixes.
  • Code Generation: Generate boilerplate code for common functionalities like user authentication or database interactions.
  • Architectural Guidance: Get advice on structuring your project and choosing appropriate technologies.

Key capabilities

  • Front-end development (likely including HTML, CSS, JavaScript)
  • Back-end development (specific languages/frameworks not specified in source)
  • Code debugging
  • Software architecture guidance
  • Code generation

Example prompts

  • "Create a simple to-do list application with React and Node.js."
  • "I'm getting this error: 'TypeError: Cannot read property 'name' of undefined'. Can you help me debug it?"
  • "What are the pros and cons of using MongoDB versus PostgreSQL for my new web app?"

Tips & gotchas

The skill’s effectiveness depends on providing clear and specific instructions. While capable, the agent may require clarification regarding preferred technologies or coding styles.
