Vast.ai Local Dev Loop
Overview
Set up a fast, reproducible local development workflow for Vast.ai.
Prerequisites
- Completed
vastai-install-authsetup - Node.js 18+ with npm/pnpm
- Code editor with TypeScript support
- Git for version control
Instructions
Step 1: Create Project Structure
my-vastai-project/
├── src/
│ ├── vastai/
│ │ ├── client.ts # Vast.ai client wrapper
│ │ ├── config.ts # Configuration management
│ │ └── utils.ts # Helper functions
│ └── index.ts
├── tests/
│ └── vastai.test.ts
├── .env.local # Local secrets (git-ignored)
├── .env.example # Template for team
└── package.json
Step 2: Configure Environment
# Copy environment template
cp .env.example .env.local
# Install dependencies
npm install
# Start development server
npm run dev
Step 3: Setup Hot Reload
{
"scripts": {
"dev": "tsx watch src/index.ts",
"test": "vitest",
"test:watch": "vitest --watch"
}
}
Step 4: Configure Testing
import { describe, it, expect, vi } from 'vitest';
import { Vast.aiClient } from '../src/vastai/client';
describe('Vast.ai Client', () => {
it('should initialize with API key', () => {
const client = new Vast.aiClient({ apiKey: 'test-key' });
expect(client).toBeDefined();
});
});
Output
- Working development environment with hot reload
- Configured test suite with mocking
- Environment variable management
- Fast iteration cycle for Vast.ai development
Error Handling
| Error | Cause | Solution |
|---|---|---|
| Module not found | Missing dependency | Run npm install |
| Port in use | Another process | Kill process or change port |
| Env not loaded | Missing .env.local | Copy from .env.example |
| Test timeout | Slow network | Increase test timeout |
Examples
Mock Vast.ai Responses
vi.mock('@vastai/sdk', () => ({
Vast.aiClient: vi.fn().mockImplementation(() => ({
// Mock methods here
})),
}));
Debug Mode
# Enable verbose logging
DEBUG=VASTAI=* npm run dev

evaluating-machine-learning-models: This skill allows Claude to evaluate machine learning models using a comprehensive suite of metrics. It should be used when the user requests model performance analysis, validation, or testing. Claude can use this skill to assess model accuracy, precision, recall, F1-score, and other relevant metrics. Trigger this skill when the user mentions "evaluate model", "model performance", "testing metrics", "validation results", or requests a comprehensive "model evaluation".

It should be used when the user requests the creation of a new neural network, modification of an existing one, or assistance with defining the layers, parameters, and training process. The skill is triggered by requests involving terms like "build a neural network," "define network architecture," "configure layers," or specific mentions of neural network types (e.g., "CNN," "RNN," "transformer").
