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 janjaszczak/cursor at cb70ff7aec.

    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 allows AI agents to build and deploy backend applications using Python and FastAPI. It handles routing, data validation, and API endpoint creation, enabling agents to create RESTful APIs for various purposes. The agent can generate code, test endpoints, and manage dependencies related to the FastAPI application.

When to use it

  • Creating a simple API: An agent needs to quickly expose data or functionality through an API without managing complex infrastructure.
  • Building a backend for a web app: An agent is tasked with developing the server-side logic and endpoints for a new web application.
  • Automating API development tasks: The agent can generate boilerplate code, handle routing configurations, and perform basic testing of API endpoints.
  • Prototyping an API quickly: Rapidly create a functional API to demonstrate concepts or test ideas before full implementation.

Key capabilities

  • FastAPI framework usage
  • Python backend development
  • RESTful API creation
  • Data validation and serialization
  • Routing configuration

Example prompts

  • "Create a FastAPI endpoint that returns 'Hello, world!'"
  • "Generate a Python script with a FastAPI application that accepts GET requests to /items/{item_id}."
  • "Build an API for managing user accounts with endpoints for creating, reading, updating, and deleting users."

Tips & gotchas

The agent requires a working Python environment with FastAPI installed. While it can generate code, understanding of basic Python programming concepts is helpful to review and customize the generated application.
