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

The debug:express skill assists in debugging Express.js applications. It can analyze error messages, identify potential causes of issues within the application code, and suggest fixes. This skill is particularly useful for pinpointing problems related to middleware configuration or route handling.

When to use it

  • You're encountering a 500 Internal Server Error in your Express app and need help understanding the cause.
  • Your API routes are returning unexpected results, and you suspect a problem with middleware execution order.
  • You’ve received error logs from production but lack context to understand the root of the issue.
  • You're refactoring an existing Express application and want assistance in identifying potential bugs introduced during the process.

Key capabilities

  • Error message analysis
  • Middleware configuration debugging
  • Route handling troubleshooting
  • Code suggestion for fixes

Example prompts

  • "I’m getting a 500 error, here's the stack trace: [paste stack trace]"
  • "My /users route isn't working. Here's my code: [paste relevant code snippet]"
  • "Can you help me understand why this middleware is causing an issue? [paste middleware code]"

Tips & gotchas

The skill requires access to the relevant application code or error logs for effective debugging. Providing clear and concise information about the problem will yield better results.
