AI DevKit

A CLI toolkit for AI-assisted software development with structured phase templates and environment setup for Cursor and Claude Code.

Features

• 🎯 Phase-based Development: Structured templates for each stage of the software development lifecycle
• 🤖 AI Environment Setup: Automatic configuration for Cursor and Claude Code
• 📝 Customizable Templates: Markdown-based templates with YAML frontmatter
• 🚀 Interactive CLI: User-friendly prompts with flag override support
• ⚙️ State Management: Tracks initialized phases and configuration

Installation

# Using npx (no installation needed)
npx ai-devkit init

# Or install globally
npm install -g ai-devkit

Quick Start

Initialize AI DevKit in your project:

# Interactive mode (recommended)
ai-devkit init

# With flags
ai-devkit init --environment cursor --all

# Initialize specific phases
ai-devkit init --phases requirements,design,planning

This will:

1. Create a .ai-devkit.json configuration file
2. Set up your AI development environment (Cursor/Claude Code)
3. Generate phase templates in docs/ai/

Available Phases

• Requirements: Problem understanding, requirements gathering, and success criteria
• Design: System architecture, data models, and technical design (include mermaid diagrams for architecture/data flow)
• Planning: Task breakdown, milestones, and project timeline
• Implementation: Technical implementation notes and code guidelines
• Testing: Testing strategy, test cases, and quality assurance
• Deployment: Deployment process, infrastructure, and release procedures
• Monitoring: Monitoring strategy, metrics, alerts, and observability

Commands

ai-devkit init

Initialize AI DevKit in your project.

Options:

• -e, --environment <env>: Specify environment (cursor|claude|both)
• -a, --all: Initialize all phases at once
• -p, --phases <phases>: Comma-separated list of specific phases

Examples:

# Interactive mode
ai-devkit init

# Initialize for Cursor with all phases
ai-devkit init --environment cursor --all

# Initialize specific phases
ai-devkit init --phases requirements,design,implementation

ai-devkit phase [name]

Add or update a specific phase template.

Examples:

# Interactive selection
ai-devkit phase

# Add specific phase
ai-devkit phase requirements
ai-devkit phase testing

Customizing Templates

All templates are plain Markdown files with YAML frontmatter. You can customize them to fit your project's needs:

---
phase: requirements
title: Requirements & Problem Understanding
description: Clarify the problem space, gather requirements, and define success criteria
---

# Your custom content here

Templates are designed to provide structure while remaining concise and AI-friendly.

Environment Setup

Cursor

Generated files:

• .cursor/rules/: Project-specific rules as Markdown files (per Cursor documentation)
• .cursor/commands/: Custom slash commands as Markdown files (per Cursor documentation)

Available slash commands:

• /new-requirement: Complete workflow for adding a new feature from requirements to PR
• /code-review: Structured local code review against design docs before pushing changes
• /execute-plan: Walk a feature plan task-by-task with interactive prompts
• /writing-test: Write unit/integration tests targeting 100% coverage
• /update-planning: Update planning and task breakdown
• /check-implementation: Compare implementation with design
• /review-design: Review system design and architecture
• /review-requirements: Review and summarize requirements

Each command is stored as a plain Markdown file in .cursor/commands/ and will automatically appear when you type / in Cursor's chat input.

Claude Code

Generated files:

• .claude/CLAUDE.md: Workspace configuration and guidelines
• .claude/commands/: Custom commands as Markdown files

Available commands:

• new-requirement - Complete workflow for adding a new feature from requirements to PR
• code-review - Structured local code review against design docs before pushing changes
• execute-plan - Walk a feature plan task-by-task with interactive prompts
• writing-test - Write unit/integration tests targeting 100% coverage
• update-planning - Update planning and task breakdown
• check-implementation - Compare implementation with design
• review-design - Review system design and architecture
• review-requirements - Review and summarize requirements

Commands can be referenced in Claude Code chats to guide AI assistance through your development phases.

Workflow Examples

Initial Project Setup

1. Initialize your project:

   ai-devkit init

2. Start with requirements:

   • Fill out docs/ai/requirements/README.md
   • Use your AI assistant to help clarify and document requirements

3. Design your system:

   • Complete docs/ai/design/README.md and feature-specific files
   • Include mermaid diagrams for architecture, component interactions, and data flow
   • Reference requirements when making design decisions

4. Plan your work:

   • Break down tasks in docs/ai/planning/README.md
   • Estimate and prioritize

5. Implement with guidance:

   • Follow patterns in docs/ai/implementation/README.md
   • Keep implementation notes updated

6. Test thoroughly:

   • Use docs/ai/testing/README.md as your testing guide
   • Document test cases and results

7. Deploy confidently:

   • Follow deployment procedures in docs/ai/deployment/README.md

8. Monitor and iterate:

   • Set up monitoring per docs/ai/monitoring/README.md

Adding a New Feature

Use the /new-requirement command for a guided workflow:

1. In Cursor or Claude Code, type /new-requirement
2. The AI will guide you through:
   • 📋 Capturing requirement details
   • 🔍 Creating feature-specific documentation
   • 📐 Designing the solution
   • 📅 Planning tasks and breaking down work
   • 💻 Implementation (task by task)
   • ✅ Testing and verification
   • 🔀 Git commits and PR/MR creation

Review and refine your documentation:

• After drafting requirements, run /review-requirements to validate completeness
• After drafting design, run /review-design to ensure architecture clarity and mermaid diagrams

Execute your plan:

• Run /execute-plan to step through tasks interactively:
  • Reads docs/ai/planning/feature-{name}.md
  • Presents tasks in order with context
  • Captures status/notes for each task
  • Prompts you to update documentation as you progress

Before pushing your code:

• Run /code-review to perform a structured local review:
  • Checks alignment with design docs
  • Spots logic/security/performance issues
  • Highlights redundant code and missing tests
  • Suggests documentation updates

Generate comprehensive tests:

• Run /writing-test to create unit and integration tests targeting 100% coverage

This workflow creates feature-specific files:

• docs/ai/requirements/feature-{name}.md
• docs/ai/design/feature-{name}.md
• docs/ai/planning/feature-{name}.md
• docs/ai/implementation/feature-{name}.md
• docs/ai/testing/feature-{name}.md

Use Cases

• New Projects: Scaffold complete development documentation
• Existing Projects: Add structured documentation gradually
• Team Collaboration: Share common development practices
• AI Pair Programming: Provide context for AI assistants
• Knowledge Management: Document decisions and patterns

Best Practices

1. Keep templates updated: As your project evolves, update phase documentation
2. Reference across phases: Link requirements to design, design to implementation
3. Use with AI assistants: Templates are designed to work well with AI code assistants
4. Customize for your needs: Templates are starting points, not rigid requirements
5. Track decisions: Document architectural decisions and their rationale

Configuration File

The .ai-devkit.json file tracks your setup:

{
  "version": "0.2.0",
  "environment": "cursor",
  "initializedPhases": ["requirements", "design", "planning"],
  "createdAt": "2025-10-14T...",
  "updatedAt": "2025-10-14T..."
}

Development

To work on ai-devkit itself:

# Clone the repository
git clone <repository-url>
cd ai-devkit

# Install dependencies
npm install

# Run in development mode
npm run dev init

# Build
npm run build

# Test locally
npm link
ai-devkit init

Note: ai-devkit init now ensures the current directory is a git repository. If git is available and the repo isn't initialized, it will run git init automatically.
