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 raudbjorn/claude at bd02b72353.

    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 enables real-time data updates from a Supabase database. It allows an AI agent to subscribe to changes in specific tables and receive immediate notifications when those changes occur, facilitating dynamic applications and reactive workflows. The agent can then react to these updates programmatically without needing to constantly poll the database.

When to use it

  • Live dashboards: Displaying real-time data visualizations based on Supabase table updates (e.g., live chat counts, inventory levels).
  • Automated notifications: Triggering actions or sending alerts when specific events occur in a Supabase database (e.g., new order placed, user signup).
  • Collaborative applications: Keeping multiple users synchronized with changes made by others in real-time (e.g., shared document editing).
  • Real-time game development: Updating game state and player positions based on data stored in a Supabase database.

Key capabilities

  • Subscribe to table updates
  • Receive immediate notifications of changes
  • Works with Supabase databases

Example prompts

  • "Listen for new entries in the 'orders' table."
  • "Notify me when the 'status' field in the 'payments' table changes to 'failed'."
  • “Show me updates from the ‘messages’ table.”

Tips & gotchas

  • Requires a Supabase project and API key.
  • Be mindful of potential costs associated with real-time subscriptions, especially for high-volume data streams.
