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 thebushidocollective/han at 19caa51d5f.

    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 allows AI agents to analyze and optimize the performance of Vitest test suites. It identifies bottlenecks in tests, provides insights into execution times for individual tests, and suggests strategies for improving overall test suite speed. The skill aims to reduce testing time and improve developer productivity by pinpointing areas where tests can be made more efficient.

When to use it

  • Slow Test Suites: When your Vitest test suites are taking an excessively long time to run, hindering development cycles.
  • Performance Regression Detection: To identify performance degradations in existing test suites after code changes or dependency updates.
  • Test Optimization Efforts: As part of a broader initiative to improve the efficiency and reliability of your testing process.
  • Debugging Slow Tests: When you suspect that specific tests are unusually slow and need detailed analysis.

Key capabilities

  • Performance profiling of Vitest test suites.
  • Identification of slowest tests within a suite.
  • Insights into execution time breakdowns for individual tests.
  • Recommendations for optimizing test performance.

Example prompts

  • "Analyze the performance of my Vitest test suite and identify any bottlenecks."
  • "Show me the slowest tests in my project's 'components/button.test.ts' file."
  • "Give me suggestions on how to improve the speed of my Vitest tests."

Tips & gotchas

This skill requires a Vitest testing environment to be set up and running within your project. It is most effective when used proactively, rather than reactively addressing performance issues after they become critical.
