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.

About this skill

What it does

The browser-extension-builder skill enables users to create custom browser extensions with ease. It provides tools for writing, testing, and packaging extensions directly within the AI agent interface, eliminating the need for complex setup or external development environments.

When to use it

  • You want to build a lightweight tool that runs in the browser without requiring server-side code.
  • You're developing an ad-blocker or content filter for personal or team use.
  • You need to quickly prototype and test a browser extension idea before full deployment.

Key capabilities

  • Code generation for manifest files and background scripts
  • Live preview of extension functionality in the browser
  • Packaging and exporting as .crx or .zip files

Example prompts

  • "Create a browser extension that highlights all links on a page."
  • "Generate a manifest file for an ad-blocker extension."
  • "Package my current extension code into a downloadable ZIP file."

Tips & gotchas

  • Ensure you have basic knowledge of JavaScript and the Chrome Extension API.
  • Some advanced features may require manual configuration outside the AI agent interface.
