What it does

Unit Tests is an agent skill from genlayerlabs/genlayer-studio. Setup Python virtual environment and run unit tests with gltest

Its SKILL.md is about 440 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering Unit testing. It works with Python. The repository describes itself as: An interactive sandbox to explore the GenLayer Protocol. The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit c940729. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- pip
- brew
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Unit Tests loads about 441 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 48 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~19
When it runs · the whole SKILL.md, loaded when a task matches: ~441

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Run Unit Tests

Setup the Python environment and run unit tests for GenLayer Studio.

Prerequisites

Python 3.12 installed
virtualenv installed (pip install virtualenv)

Setup Virtual Environment (first time or reset)

bash

# Remove existing venv if present
rm -rf .venv

# Create new venv with Python 3.12
virtualenv -p python3.12 .venv

# Activate
source .venv/bin/activate

# Upgrade pip
pip install --upgrade pip

# Install all dependencies
pip install -r requirements.txt
pip install -r requirements.test.txt
pip install -r backend/requirements.txt

# Set Python path
export PYTHONPATH="$(pwd)"

Run Tests

bash

# Activate venv (if not already)
source .venv/bin/activate
export PYTHONPATH="$(pwd)"

# Run all unit tests
gltest --contracts-dir . tests/unit

# Run specific test file
gltest --contracts-dir . tests/unit/test_specific.py

# Run with verbose output
gltest --contracts-dir . tests/unit -v

# Run specific test function
gltest --contracts-dir . tests/unit/test_file.py::test_function_name

Quick One-Liner (after initial setup)

bash

source .venv/bin/activate && export PYTHONPATH="$(pwd)" && gltest --contracts-dir . tests/unit

Troubleshooting

Python 3.12 Not Found

bash

# Check available Python versions
which python3.12

# On macOS with Homebrew
brew install python@3.12

gltest Command Not Found

bash

# Make sure venv is activated
source .venv/bin/activate

# Reinstall test dependencies
pip install -r requirements.test.txt

Import Errors

bash

# Ensure PYTHONPATH is set

Questions about Unit Tests

What does Unit Tests do?

Setup Python virtual environment and run unit tests with gltest. Unit Tests is an agent skill from genlayerlabs/genlayer-studio.

When should I use Unit Tests?

Unit Tests fits situations like: tasks that involve Unit testing.

How do I install Unit Tests in Claude Code?

Run `npx skills add genlayerlabs/genlayer-studio --skill unit-tests -a claude-code`. Or copy the skill folder (.claude/skills/unit-tests in genlayerlabs/genlayer-studio) into .claude/skills/unit-tests in your project. Claude Code loads it when a task matches its description.

How do I install Unit Tests in Codex?

Run `npx skills add genlayerlabs/genlayer-studio --skill unit-tests -a codex`. Or copy the skill folder (.claude/skills/unit-tests in genlayerlabs/genlayer-studio) into .agents/skills/unit-tests in your project. Codex loads it when a task matches its description.

Can I use Unit Tests in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add genlayerlabs/genlayer-studio --skill unit-tests -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/unit-tests, .gemini/skills/unit-tests, .github/skills/unit-tests and .opencode/skills/unit-tests in your project.

What does Unit Tests need to run?

Going by SKILL.md and its folder, Unit Tests needs the command-line tools its instructions call (pip and brew). Our summary lists: Python 3.
