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 pproenca/dot-skills at cf93c57cac.

    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 provides a comprehensive guide to Ruby on Rails testing best practices, maintained by Community. It offers 46 rules across eight categories, prioritized by impact, to assist with automated test generation, code review, and refactoring. The goal is to improve the quality and efficiency of Rails test suites.

When to use it

  • When writing new RSpec tests for models, requests, system tests, or jobs.
  • During setup of FactoryBot factories using traits and sequences.
  • While writing Capybara system tests to cover user journeys.
  • When reviewing existing test code for potential anti-patterns like flaky tests or slow specs.

Key capabilities

  • Provides a prioritized list of 46 testing rules across eight categories (Test Design & Structure, Test Data Management, Model Testing, Request & Controller Testing, System & Acceptance Testing, Async & Background Job Testing, Test Performance & Reliability, and Test Organization & Maintenance).
  • Offers specific guidelines for test design, such as using a four-phase test structure and focusing on observable behavior.
  • Includes references to detailed documentation for each rule (e.g., design-four-phase-test).

Example prompts

  • "Show me the rules related to Test Design & Structure."
  • "What are the best practices for testing background jobs in Rails?"
  • "How should I structure a test using FactoryBot?"

Tips & gotchas

  • The skill focuses on RSpec and Capybara, common tools within the Ruby on Rails ecosystem.
  • Prioritize rules based on their impact level (CRITICAL, HIGH, MEDIUM-HIGH, MEDIUM, LOW-MEDIUM) to focus your efforts effectively.
  • Refer to the detailed documentation linked for each rule to understand implementation details.
