🤖 What is The Agentic Startup?

The Agentic Startup is a spec-driven development framework for Claude Code. Create comprehensive specifications before coding, then execute with parallel specialist agents—Y Combinator energy meets engineering discipline.

Key Features:

• Native Claude Code Integration — Marketplace plugins with zero configuration
• Spec-Driven Development — PRD → SDD → Implementation Plan → Code
• Parallel Agent Execution — Multiple specialists work simultaneously
• Quality Gates — Built-in validation at every stage

Installation

Requirements: Claude Code v2.0+ with marketplace support

curl -fsSL https://raw.githubusercontent.com/rsmdt/the-startup/main/install.sh | sh

This installs the core plugins, configures the default output style, and sets up the statusline with a customizable config file.

# Add The Agentic Startup marketplace
/plugin marketplace add rsmdt/the-startup

# Install the Start plugin (core workflows)
/plugin install start@the-startup

# (Optional) Install the Team plugin (specialized agents)
/plugin install team@the-startup

After installation:

# (Optional) Create project governance rules
/start:constitution                # Auto-enforced during specify, implement, review

# Switch output styles anytime
/output-style start:The Startup    # High-energy, fast execution (default)
/output-style start:The ScaleUp    # Calm confidence, educational

🚀 Quick Start

Create a specification and implement it:

# Create a specification
/start:specify Add user authentication with OAuth support

# Execute the implementation
/start:implement 001

That's it! You're now using spec-driven development.

📖 The Complete Workflow

The Agentic Startup follows spec-driven development: comprehensive specifications before code, ensuring clarity and reducing rework.
