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 kevmoo/dash_skills at 0b6371c265.

    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 best practices for using matcher in Dart, a powerful library designed to simplify testing and pattern matching. It helps developers write more readable, maintainable, and robust test assertions by leveraging advanced matching capabilities.

When to use it

  • Writing unit tests where you need flexible assertion logic without strict type constraints.
  • Implementing complex pattern matching scenarios in Dart applications.
  • Ensuring code quality and readability when building test suites for larger projects.
  • Avoiding common pitfalls associated with manual comparison logic in testing frameworks.

Key capabilities

  • Simplifies the process of writing effective test assertions in Dart.
  • Offers advanced pattern matching features to handle complex data structures.
  • Enhances code maintainability by promoting standardized testing patterns.
  • Reduces boilerplate code typically required for custom comparison logic.

Example prompts

  • "How can I use matcher to assert that a list contains specific elements in any order?"
  • "What are the best practices for writing readable assertions using Dart's matcher library?"
  • "Show me an example of using isNotNull and isNotEmpty matchers in a unit test."

Tips & gotchas

Ensure you have the latest version of the matcher package installed to access all current features. While powerful, overusing complex matchers can sometimes make tests harder to debug; keep assertions clear and focused on specific behaviors.
