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 28 Sept 2026

This skill failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

Declares what it does: failed
No SKILL.md was found in the skill's directory.
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 github/awesome-copilot at 6c4d33b9cf.
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

The java-junit skill enables AI agents to write, execute, and interpret JUnit tests in Java. It supports creating unit tests for methods, asserting expected outcomes, and identifying test failures or errors. This helps ensure code correctness and maintainability in Java projects.

When to use it

Writing automated unit tests for Java classes during development.
Debugging failing tests by analyzing error messages and stack traces.
Refactoring legacy Java code with test coverage to prevent regressions.

Key capabilities

Generating JUnit test cases for Java methods.
Executing tests and reporting results (pass/fail).
Interpreting test failures and suggesting fixes.

Example prompts

"Write a JUnit test for the calculateSum method in the MathUtils class."
"Run all tests in the com.example.tests package and report any failures."
"Fix the failing test in TestUserDAO.java caused by an incorrect SQL query."

Tips & gotchas

Ensure your Java environment is properly configured with JUnit dependencies.
Some complex scenarios, like testing asynchronous or database-driven code, may require additional setup beyond basic JUnit support.
