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.

About this skill

What it does

This skill enables AI agents to read and inspect Supabase storage buckets, allowing for the discovery of stored files and verification of access permissions. It is specifically designed for security auditing and penetration testing workflows within Supabase environments.

When to use it

  • Auditing public storage buckets to identify exposed or sensitive user-uploaded files.
  • Verifying that private bucket policies are correctly restricting unauthorized read access.
  • Performing pre-deployment checks on file storage configurations in a development environment.
  • Investigating potential data leaks by scanning bucket contents for unexpected file types.

Key capabilities

  • Reads metadata and content of files within specified Supabase buckets.
  • Validates current access control lists (ACLs) and policy rules.
  • Integrates directly with the Supabase Pentest Skills suite for automated security checks.

Example prompts

  • "Audit all public buckets in my Supabase project to list accessible file paths."
  • "Check if the 'user-profiles' bucket allows read access from unauthenticated users."
  • "Scan the storage configuration for any buckets with overly permissive read policies."

Tips & gotchas

Ensure you have valid authentication credentials and appropriate permissions before attempting to read private buckets. This skill is part of a broader pentest suite; use it only in authorized testing environments to avoid triggering security alerts or violating data privacy laws.
