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 yoanbernabeu/supabase-pentest-skills at 0f9612276b.

    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 extracts anonymous API keys from Supabase projects, enabling AI agents to interact with database instances without requiring user authentication tokens. It is specifically designed for security auditing and penetration testing scenarios where access verification is necessary.

When to use it

  • Automating security assessments of public or misconfigured Supabase deployments.
  • Verifying whether an application inadvertently exposes credentials in source code or environment variables.
  • Simulating unauthorized access attempts to test database isolation controls.
  • Recovering lost access when only the project URL is known but no valid key exists.

Key capabilities

  • Parses Supabase project configurations to locate anonymous keys.
  • Validates extracted keys against active Supabase instances.
  • Integrates with AI agent workflows for automated security testing pipelines.

Example prompts

  • "Extract the anonymous API key from this Supabase project configuration file."
  • "Scan the provided codebase for exposed Supabase anon keys and report findings."
  • "Use the extracted anon key to query the public tables in this Supabase instance."

Tips & gotchas

This skill should only be used on systems you own or have explicit permission to test. Extracting anonymous keys from unauthorized projects may violate terms of service or laws. Always verify project ownership before attempting extraction.
