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

About this skill

What it does

This skill enables AI agents to programmatically extract Supabase service keys from configuration files or environment variables. It automates the retrieval of authentication credentials necessary for connecting to Supabase databases, streamlining setup and testing workflows without manual copy-pasting.

When to use it

  • Automating database connection initialization in CI/CD pipelines.
  • Quickly retrieving credentials during local development environment provisioning.
  • Validating access permissions by programmatically inspecting active service keys.
  • Integrating Supabase authentication into custom scripts or automation tools.

Key capabilities

  • Parses various configuration formats to locate embedded keys.
  • Extracts specific Supabase service key strings accurately.
  • Supports integration within broader AI agent workflows for database access.

Example prompts

  • "Extract the Supabase service key from my current project's environment variables."
  • "Locate and output the service key defined in this configuration file for my Supabase instance."
  • "Retrieve the authentication service key needed to connect to my Supabase database programmatically."

Tips & gotchas

Ensure your AI agent has read access to the specific files or environment where the keys are stored, as extraction depends on available context. Be cautious when handling extracted keys in logs or output to prevent accidental exposure of sensitive credentials.
