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 poletron/custom-rules at aba6668777.

    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

The poletron-express skill provides a framework for building and deploying Express.js applications within an AI agent environment. It handles routing, middleware management, and request handling, allowing agents to create simple web servers or APIs. This enables agents to expose functionality through HTTP endpoints.

When to use it

  • Creating Simple APIs: When you need your AI agent to provide data or services via a basic API endpoint.
  • Webhooks: To enable the agent to receive and process incoming webhook requests from external services.
  • Internal Tools: For building lightweight internal tools accessible through a web interface.
  • Rapid Prototyping: Quickly test and deploy backend logic without complex infrastructure setup.

Key capabilities

  • Express.js framework integration
  • Routing functionality
  • Middleware management
  • Request handling

Example prompts

  • "Create an endpoint at /hello that returns 'Hello, world!'"
  • "Add a middleware function to log all incoming requests."
  • "Deploy the Express application to a test environment."

Tips & gotchas

This skill requires familiarity with JavaScript and basic web development concepts. The agent's capabilities are limited by the underlying infrastructure available for deployment; complex deployments may require additional configuration.
