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 snakeo/claude-debug-and-refactor-skills-plugin at e2e79df88e.

    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 assists in debugging FastAPI applications. It can analyze error messages, identify potential causes of issues within the code, and suggest fixes for common problems encountered during development. The tool aims to streamline the debugging process and accelerate problem resolution for FastAPI projects.

When to use it

  • You're encountering unexpected errors or behavior in your FastAPI application.
  • You need help understanding a complex error message from your FastAPI server.
  • You are looking for suggestions on how to improve the performance of an endpoint.
  • You want assistance identifying and resolving issues related to data validation within your API.

Key capabilities

  • Error analysis
  • Root cause identification
  • Fix suggestion
  • Performance optimization advice

Example prompts

  • "I'm getting a 500 error on my FastAPI endpoint /items/. Can you help me debug it?"
  • "This is the traceback from my FastAPI application: [paste traceback here]. What could be causing this issue?"
  • "How can I improve the performance of my FastAPI endpoint that handles image uploads?"

Tips & gotchas

The skill's effectiveness depends on providing clear and complete error messages or code snippets. It is designed for debugging, not writing, FastAPI applications from scratch.
