What is gh-envcheck?
EnvCheck serves as a vital infrastructure component for developers and automated systems working with AI agents. It provides a standardized API to perform pre-flight checks, ensuring that all necessary dependencies—such as specific environment variables and CLI binaries—are correctly configured before a workflow begins. This utility is designed to integrate seamlessly into the ecosystem of Openclaw Skills, helping to prevent runtime errors caused by missing paths or unset configuration keys.
By exposing a simple FastAPI-based endpoint, EnvCheck allows agents or shell scripts to programmatically confirm system readiness. This is particularly useful in multi-agent environments or containerized setups where environment parity is essential for consistent performance across different nodes.
gh-envcheck Use Cases
- Verifying system dependencies before launching complex Openclaw Skills workflows.
- Automated environment auditing during CI/CD pipeline execution.
- Programmatic health checks for containerized AI agent environments.
- Dynamic dependency resolution when paired with static analysis tools like ScopeCheck.
How gh-envcheck Works
- The user or an automated supervisor starts the EnvCheck server on a designated port.
- A POST request is sent to the /v1/check-env endpoint containing a JSON payload of required_env and required_bins.
- The skill checks the local OS environment for the existence of the specified keys.
- The skill attempts to locate the specified binaries within the system PATH.
- A structured JSON response is returned containing a ready boolean and detailed lists of present and missing requirements.
gh-envcheck Setup
To get started with this utility, ensure you have python installed and then set up the server:
# Install required dependencies
uv pip install fastapi uvicorn pydantic
# Start the EnvCheck server
uvicorn envcheck.app:app --port 8007
You can then test the environment using curl:
curl -s -X POST http://localhost:8007/v1/check-env \
-H "Content-Type: application/json" \
-d '{"required_env": ["HOME", "PATH"], "required_bins": ["python", "git"]}' | jq
gh-envcheck Data Schema & Taxonomy
The skill returns a structured JSON object to help orchestrators decide whether to proceed with Openclaw Skills execution:
| Property | Type | Description |
|---|---|---|
ready |
Boolean | True if every required environment variable and binary is found. |
present_env |
Array | A list of environment variables successfully detected. |
missing_env |
Array | A list of environment variables that were requested but not found. |
present_bins |
Array | A list of CLI binaries found on the system PATH. |
missing_bins |
Array | A list of CLI binaries missing from the system PATH. |
gh-envcheck Advanced Features
- Intelligent pairing with ScopeCheck to automatically extract requirements from SKILL.md files and verify them in real-time.
- High-performance FastAPI backend suitable for high-frequency environment polling.
- Pydantic-validated request/response models for robust integration with other Openclaw Skills.
- CLI-friendly output that integrates perfectly with jq for shell-based automation scripts.
