Automated safety checks
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.

About this skill
What it does
The m15-anti-pattern skill helps identify and avoid common anti-patterns in software development, particularly within Rust projects. It analyzes code structures, design choices, and implementation strategies to flag practices that may lead to inefficiencies, bugs, or maintenance challenges.
When to use it
- During code reviews to catch problematic patterns before they are merged into the main branch.
- When refactoring legacy code to ensure adherence to best practices.
- Before deploying a new feature to verify that no harmful design choices were made.
- As part of an automated CI/CD pipeline to enforce coding standards and quality.
Key capabilities
- Detects overuse of global state or singletons in Rust applications.
- Identifies unnecessary complexity in function signatures or module structures.
- Highlights improper error handling patterns that may lead to silent failures.
- Warns against unsafe code practices that violate Rust's safety guarantees.
Example prompts
- "Analyze this Rust module for anti-patterns."
- "Check the use of
unsafeblocks in this file for potential issues." - "Review the function signature and suggest improvements."
Tips & gotchas
- This skill works best when used alongside a linter or static analysis tool for comprehensive code quality checks.
- It may not catch all anti-patterns, especially those that are context-specific or require domain knowledge to identify.
