Purpose-Driven Development (PDD) Framework

Purposely helps you stay aligned with your project's core purpose throughout the entire development lifecycle.

🎯 Core Concept

Every project must have a GLOBAL_PURPOSE that defines:

• Why does this project exist? (Why)
• What problem does it solve? (Problem)
• How will it solve the problem? (Solution)
• How do we measure success? (Success Metrics)

All Phases, Designs, and Implementations must continuously align with this GLOBAL_PURPOSE.

🚀 Quick Start

Prerequisites

Install uv (recommended):

# macOS/Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"

Initialize Your Project

Run directly without installation using uvx:

# In your project directory
uvx --from git+https://github.com/nicered/purposely purposely init --lang en

# Or in Korean
uvx --from git+https://github.com/nicered/purposely purposely init --lang ko

Note: After PyPI publication, you can simply use uvx purposely init --lang en

This command creates:

• .purposely/config.json - Project configuration
• docs/ - Documentation directory
• .claude/ - Claude Code slash commands and templates

Upgrading Purposely

When a new version of Purposely is released, upgrade your project templates:

# Check for updates and upgrade
purposely upgrade

# Force reinstall templates even if at latest version
purposely upgrade --force

This updates:

• Slash commands (.claude/commands/)
• Instructions (.claude/instructions.md)
• Config version (.purposely/config.json)

Your documents are preserved - only templates are updated.

Creating Documents

Use the purposely create command to create documents:

# Create GLOBAL_PURPOSE
purposely create global-purpose

# Create a new phase
purposely create spec 01

# Create research documents
purposely create research 01 01 "Technology Stack Research"

# Create design documents
purposely create design-overview 01
purposely create design 01 01 "UserService"

# Create plan and implementation
purposely create plan 01
purposely create implementation 01

Using with Claude Code

Purposely is designed for AI-guided collaborative development. Use slash commands for interactive document creation:

1. Create GLOBAL_PURPOSE: /purposely-init

   • AI asks probing questions to understand your true purpose
   • Challenges vague answers, requires measurable metrics
   • Writes the document based on conversation

2. Start a Phase: /purposely-phase

   • AI reads GLOBAL_PURPOSE first, validates alignment
   • Challenges scope creep ruthlessly
   • Ensures all objectives connect to GLOBAL_PURPOSE

3. Document Research: /purposely-research

   • AI validates research necessity against SPEC
   • Prevents analysis paralysis
   • Connects findings to design decisions

4. Write Design: /purposely-design

   • AI reads GLOBAL_PURPOSE + SPEC + RESEARCH
   • Challenges over-engineering
   • Validates design against Success Criteria

5. Create Plan: /purposely-plan

   • AI reads all previous documents
   • Validates plan achieves all Success Criteria
   • Checks timeline feasibility

6. Track Implementation: /purposely-implement

   • AI compares actual vs planned
   • Extracts honest learnings
   • Prepares notes for next phase

The AI is your alignment guardian - it reads all previous documents and validates every decision against GLOBAL_PURPOSE.

🌟 Key Features

• Purpose-Driven Development: All documents reference GLOBAL_PURPOSE
• Structured Documentation: 7 document types with clear hierarchy
• i18n Support: English and Korean
• Claude Code Integration: Easy document creation with slash commands
• Consistency Checking: AI automatically checks alignment with purpose

📚 Document Types

GLOBAL_PURPOSE

The core purpose of your project. The foundation of everything.

SPEC (00_SPEC.md)

Defines objectives, scope, and success criteria for each phase.

RESEARCH (01_XX_RESEARCH_*.md)

Research and investigation results. Evidence for design decisions.

DESIGN (02_XX_DESIGN_*.md)

System design. How will it be implemented?

PLAN (03_PLAN.md)

Concrete implementation plan. Timeline, dependencies, risks.

IMPLEMENTATION (04_IMPLEMENTATION.md)

Actual implementation log. What was learned? How did it differ from the plan?
