​
Overview

The SynapseX CLI provides a comprehensive set of AI-powered development capabilities directly in your terminal. Whether you’re building a new project from scratch, debugging complex issues, or deploying to production, SynapseX CLI handles it all through natural language commands.

​
Project Development

Build complete, production-ready projects with a single command: 
synapsex "create a full-stack SaaS application with Next.js frontend, FastAPI backend,
PostgreSQL database, Stripe payments, and user authentication"
SynapseX will:
  • Scaffold the complete project structure
  • Install and configure all dependencies
  • Write boilerplate code with best practices applied
  • Set up environment configuration files
  • Generate a README with setup instructions
Supported project types:
TypeExample Command
Web APIsynapsex "create a REST API with FastAPI and SQLAlchemy"
Frontend Appsynapsex "create a React app with TypeScript, Tailwind, and React Query"
Full-Stacksynapsex "create a Next.js app with Prisma and NextAuth"
CLI Toolsynapsex "create a Node.js CLI tool with Commander.js"
Microservicesynapsex "create a message consumer microservice with Kafka and Docker"

​
Debugging & Testing

Identify and fix bugs faster with AI-powered analysis: 
# Describe the error
synapsex "getting CORS errors when calling the API from the frontend. Fix the backend config."

# Paste a stack trace
synapsex "TypeError: Cannot read properties of null (reading 'id')
  at UserController.getProfile (src/controllers/user.ts:45:23)"

# Run tests and fix failures
synapsex "run the test suite and fix any failing tests"
Testing capabilities:
  • Generate comprehensive unit tests from scratch
  • Add integration and end-to-end tests
  • Fix failing tests with context-aware analysis
  • Enforce coverage thresholds
  • Mock external dependencies automatically

​
Build & Deployment

Automate build and deployment workflows: 
synapsex "set up a GitHub Actions CI/CD pipeline for this project with automated tests,
Docker build, and deploy to Azure Container Apps"

synapsex "create a production Dockerfile with multi-stage build and security hardening"

synapsex "deploy the current build to staging and run smoke tests"
Supported platforms:
  • Azure Container Apps, Azure App Service, Azure Functions
  • Docker and Docker Compose
  • GitHub Actions, GitLab CI, CircleCI
  • Vercel, Netlify (static deployments)

​
Multi-Language Support

SynapseX CLI works fluently across all major programming languages and frameworks:

Python

FastAPI, Django, Flask, SQLAlchemy, Pydantic, PyTest

TypeScript / JavaScript

Node.js, Next.js, React, Express, NestJS, Prisma

Go

Standard library, Gin, Echo, GORM

Rust

Tokio, Actix, Axum, Serde

Java / Kotlin

Spring Boot, Gradle, Maven

C# / .NET

ASP.NET Core, Entity Framework, Azure SDK

​
Intelligent File Management

SynapseX understands your project structure and manages files intelligently: 
# Reorganize a messy codebase
synapsex "reorganize the src directory to follow feature-based architecture"

# Rename with full refactoring
synapsex "rename UserController to AccountController across the entire codebase"

# Generate documentation
synapsex "create API documentation from the route definitions in the routes/ directory"

# Clean up unused code
synapsex "find and remove all unused imports, variables, and dead code"

​
Natural Language Processing

No memorizing CLI flags or syntax — just describe what you want: 
# Plain English works perfectly
synapsex "add pagination to the users endpoint"
synapsex "make the login endpoint rate-limited to 5 attempts per minute per IP"
synapsex "add Redis caching to all database read operations with 5-minute TTL"

# Technical descriptions also work
synapsex "implement the repository pattern for all data access using interfaces and dependency injection"

​
Performance Optimization

Analyze and improve code performance with AI guidance: 
synapsex "profile the application and identify the top 3 performance bottlenecks"
synapsex "optimize this SQL query — it's taking 2 seconds on a table with 1M rows"
synapsex "implement database connection pooling and query caching"
synapsex "analyze the bundle size and reduce it by tree-shaking unused dependencies"

​
Web Search & Real-Time Information

SynapseX CLI can search the web for up-to-date information and incorporate it into your code — including technical news, documentation, and real-time data: 
# Search for latest library versions
synapsex "/search what is the latest stable Prisma version and update our dependencies"

# Get current documentation
synapsex "/search Next.js 15 App Router breaking changes and update our router config"

# Real-time data integration
synapsex "/search current Bitcoin price from CoinGecko API and display it in the dashboard"

# News and feeds
synapsex "/search latest tech headlines from X/Twitter about AI development"
The /search command augments SynapseX with live web data, making responses accurate for rapidly evolving technologies and real-time data requirements.

​
Multi-Agent Execution

The most powerful feature of SynapseX CLI — run multiple AI agents in parallel, each working on their own git branch simultaneously.

​
How It Works

synapsex /multi-agent build a complete authentication system with OAuth, JWT, and MFA
SynapseX automatically:
  1. Analyzes the task and breaks it into parallel sub-tasks
  2. Spawns a separate AI agent (sub-process) for each task
  3. Creates a dedicated git branch per agent:
    • multi-agent-synapsex-<timestamp>
    • multi-agent-claude-<timestamp>
    • multi-agent-gemini-<timestamp>
  4. Each agent works independently on its branch
  5. You review all branches and pick the best implementation (or merge selectively)

​
Available Agents for Multi-Agent Mode

AgentProviderBest For
synapsexSynapseX PlatformDefault — balanced quality and speed
claudeAnthropicComplex reasoning, large codebases
codexOpenAICode-specific tasks, refactoring
geminiGoogleLong context, multi-file tasks
gooseBlockAutonomous workflows, tool use
opencodeOpenCodeOpen source alternatives
qwenAlibaba CloudCost-effective at scale

​
Multi-Agent Examples

# Compare multiple AI implementations of the same feature
synapsex /multi-agent implement a caching layer for the API — compare Redis vs in-memory

# Parallelize large refactors
synapsex /multi-agent refactor the entire backend to use async/await and TypeScript strict mode

# Speed up feature development
synapsex /multi-agent add full CRUD operations for: users, products, orders, and payments

# Parallel testing strategies
synapsex /multi-agent write tests for the payment service — unit, integration, and e2e

​
Reviewing Multi-Agent Results

After agents complete: 
# View all created branches
git branch | grep multi-agent

# Compare implementations
git diff multi-agent-claude-1234 multi-agent-gemini-1234

# Merge the best result
git merge multi-agent-claude-1234
Multi-agent execution works best for tasks that can be cleanly separated. Tasks with tight dependencies are better handled sequentially.

​
Background CLI from VS Code Agent

When using the VS Code Agent, trigger CLI tasks in the background without leaving the editor: 
> /cli run the full test suite and fix any failures
> /cli build the Docker image and run it locally
> /cli deploy to staging and run smoke tests
Background CLI tasks run in a terminal tab within VS Code while you continue working in the editor.
