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.

  • No undeclared network calls: failed

    Contacts 1 host that is neither well-known infrastructure nor declared in the skill's frontmatter: abc123def.supabase.co.

    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.

  • 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 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 yoanbernabeu/supabase-pentest-skills at 0f9612276b.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

The supabase-audit-auth-users skill enables AI agents to systematically review Supabase authentication configurations and user data. It helps identify security vulnerabilities, permission misconfigurations, and potential unauthorized access points within your database instance.

When to use it

  • Before deploying a production application to ensure all auth settings are secure.
  • After adding new roles or policies to verify they don't grant excessive privileges.
  • During routine maintenance to detect anomalies in user activity logs.
  • When preparing for a security audit or compliance check involving user data.

Key capabilities

  • Analyzes Supabase authentication setup and identifies weak configurations.
  • Reviews user permissions and role assignments for potential risks.
  • Detects unauthorized access patterns or suspicious user behaviors.
  • Provides actionable recommendations to harden auth settings.

Example prompts

  • "Audit my Supabase project's authentication setup and list any security gaps."
  • "Review the current user roles and suggest improvements to restrict unnecessary access."
  • "Check for signs of unauthorized access in my Supabase user logs."

Tips & gotchas

Ensure your Supabase instance has proper logging enabled before running an audit, as missing logs can limit the skill's effectiveness. Always test changes in a staging environment first to avoid disrupting live user access.
