Install target

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 cantagestudio/cosmicatlaspacker at 686ead8da4.

    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 refactors existing test suites to ensure safety and prevent regressions during code changes. It automatically identifies potential issues, adds necessary assertions, and adjusts tests for improved reliability. The goal is to create a robust testing foundation that protects against unintended consequences of development work.

When to use it

  • When introducing significant changes to backend codebases.
  • To proactively identify and address potential safety vulnerabilities in existing test suites.
  • During refactoring efforts where maintaining functionality is critical.
  • As part of a continuous integration/continuous deployment (CI/CD) pipeline for automated testing.

Key capabilities

  • Automated identification of missing assertions.
  • Test suite regression prevention.
  • Safety net creation during code changes.
  • Automatic adjustment of tests.

Example prompts

  • "Refactor the test suite for the payment_processing module to ensure safety."
  • "Analyze and improve the existing tests in /api/users to prevent regressions."
  • “Add missing assertions to the integration tests for the authentication service.”

Tips & gotchas

This skill is most effective when applied to well-structured test suites. Complex or poorly written tests may require manual intervention alongside this automated refactoring process.
