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 secondsky/claude-skills at 8837836131.

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

About this skill

What it does

This skill enables AI agents to create and manage WebSocket servers using Bun, a modern JavaScript runtime. It leverages Bun's built-in WebSocket support integrated within Bun.serve(), allowing for real-time bidirectional communication between clients and the server. The skill provides handlers for connection events (open, close), message reception, ping/pong exchanges, and buffer draining.

When to use it

  • Building real-time applications like chat rooms or collaborative editors.
  • Creating APIs that require persistent connections, such as streaming data feeds.
  • Developing backend services needing bidirectional communication with clients.
  • Implementing simple echo servers for testing WebSocket functionality.

Key capabilities

  • Handles WebSocket connection establishment (open event).
  • Processes incoming messages from clients (message event), supporting both string and binary data.
  • Sends messages back to connected clients using ws.send().
  • Manages WebSocket disconnections (close event).
  • Provides handlers for ping/pong events to maintain connection health.
  • Includes a buffer drain handler (drain event).

Example prompts

  • "Create a simple WebSocket server that echoes back any messages it receives."
  • "Set up a Bun WebSocket server with handlers for opening and closing connections."
  • "Implement a WebSocket endpoint that sends JSON data to clients."

Tips & gotchas

  • This skill requires the Bun runtime environment to be installed.
  • The server.upgrade(req) function is crucial for upgrading HTTP requests to WebSockets.
  • Message handling supports both string and binary data types, requiring appropriate processing within your handlers.
