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 test-writer skill enables AI agents to generate automated tests for JavaScript code. It supports writing unit, integration, and end-to-end tests using popular testing frameworks like Jest or Mocha.
When to use it
- You need to quickly create test cases for new JavaScript functions.
- You want to ensure code coverage after making changes to a project.
- Your team follows a test-driven development (TDD) workflow.
- You're automating the process of setting up testing infrastructure for a JavaScript application.
Key capabilities
- Generates unit tests for individual functions
- Writes integration tests for module interactions
- Supports Jest and Mocha testing frameworks
- Can create end-to-end tests using tools like Cypress or Playwright
Example prompts
- "Write a Jest test for the
addfunction inmath.js." - "Generate integration tests for the user authentication module."
- "Create end-to-end tests for the login flow using Cypress."
Tips & gotchas
- Ensure your codebase has clear, modular functions to make testing easier.
- The skill may require additional configuration if you're using a non-standard test framework or project structure.
