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 wshobson/agents at 46891e7e60.

    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 python-anti-patterns skill helps identify and avoid common poor coding practices in Python. It provides insights into anti-patterns such as overuse of global variables, excessive use of nested loops, or improper exception handling that can lead to bugs, maintenance challenges, or performance issues.

When to use it

  • Reviewing legacy code for potential refactoring opportunities
  • Teaching best practices during code reviews or training sessions
  • Analyzing new code submissions to catch harmful patterns early

Key capabilities

  • Detection of overuse of global variables
  • Identification of excessive nested loops
  • Recognition of improper exception handling
  • Highlighting unnecessary use of singletons or static classes

Example prompts

  • "Find all instances of global variable usage in this Python script."
  • "Identify any anti-patterns related to exception handling in the provided code."
  • "Review this function for nested loops that could be optimized."

Tips & gotchas

  • This skill works best with well-documented and structured code. Poorly formatted or obfuscated scripts may yield incomplete results.
  • While it identifies common anti-patterns, it does not provide automated fixes—manual review is still required for accurate refactoring.
