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 polarsource/polar at 6a4f2f6d60.

    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 AI agents to understand and generate code related to backend development. It can assist with tasks like generating API endpoints, creating database schemas, and writing server-side logic in common languages. The agent can also help debug existing backend code snippets and suggest improvements based on best practices.

When to use it

  • API Development: Generate boilerplate code for REST APIs, including request handling and response formatting.
  • Database Design: Create SQL schemas or NoSQL database structures based on provided data models.
  • Code Debugging: Identify and suggest fixes for errors in existing backend code.
  • Server-Side Logic: Write functions and modules to handle specific business logic within a backend application.

Key capabilities

  • API endpoint generation
  • Database schema creation (SQL & NoSQL)
  • Backend code debugging
  • Server-side logic implementation

Example prompts

  • "Generate an API endpoint for creating user accounts with email and password."
  • "Write a SQL query to retrieve all orders placed in the last week."
  • "Debug this Python function: [code snippet]"
  • "Create a Node.js module to handle file uploads."

Tips & gotchas

The skill's effectiveness depends on providing clear and specific instructions regarding programming languages, frameworks, and desired functionality. It’s best used with well-defined requirements for optimal results.
