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 firebase/skills at daaf0e1577.

    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 provides foundational capabilities for authentication using Firebase Authentication. It enables AI agents to manage user sign-in methods (email/password, Google, etc.), handle user account creation and deletion, and securely verify user identities within a Firebase project. This facilitates secure access control for applications built with Firebase.

When to use it

  • User Onboarding: Guide users through the registration process using email/password or social login providers (Google).
  • Secure Access Control: Verify user identity before granting access to sensitive application features or data.
  • Account Management: Allow users to reset passwords, delete their accounts, or update profile information.
  • Automated Testing: Automate testing of authentication flows and security protocols within a Firebase environment.

Key capabilities

  • Email/Password Authentication
  • Google Sign-In Integration
  • User Account Creation
  • User Account Deletion
  • Secure User Verification

Example prompts

Tips & gotchas

  • Requires a Firebase project set up with Firebase Authentication enabled.
  • Be mindful of rate limits when performing authentication operations in an automated environment.
