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 majesticlabs-dev/majestic-marketplace at 04e97708c2.

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

About this skill

What it does

The fastapi-coder skill allows AI agents to generate FastAPI code based on natural language descriptions. It can create complete API endpoints, including request body validation and response formatting. This skill streamlines the backend development process by automating repetitive coding tasks.

When to use it

  • Rapid Prototyping: Quickly build out basic API functionality for testing or demonstration purposes.
  • API Endpoint Generation: Automate the creation of new endpoints based on specific requirements.
  • Backend Development Assistance: Generate boilerplate code and reduce manual coding effort during backend development.
  • Learning FastAPI: Explore how to implement different features by observing generated code examples.

Key capabilities

  • Generates FastAPI application code.
  • Creates API endpoints with request body validation.
  • Formats responses according to specifications.

Example prompts

  • "Create a FastAPI endpoint that accepts a JSON payload with 'name' and 'age' fields, and returns a greeting."
  • "Generate a FastAPI route for handling POST requests to /items, validating the data against a Pydantic model."
  • "Write a FastAPI API to retrieve user details by ID."

Tips & gotchas

The quality of generated code depends heavily on the clarity and specificity of the prompt. Providing detailed requirements and examples will yield better results.
