Midnight Example DApp Constitution

This constitution defines non-negotiable standards for all example dApps built with the dapp-sdd plugin.

Stack (Non-Negotiable)

• Runtime: Node.js ≥22.0.0
• Language: TypeScript 5.9+ (strict mode enabled)
• Contracts: Compact smart contracts in contracts/ directory
• SDK: Midnight SDK packages (@midnight-ntwrk/*)
• Scaffold: Project structure from create-mn-app

Code Quality (Zero Tolerance)

All code must pass quality checks with zero warnings or errors:

Quality gates are mandatory before every commit.

Example App Standards

Educational Focus

• README.md must explain what the dApp demonstrates
• Code should be readable and educational (clarity over cleverness)
• Include inline comments explaining Midnight-specific concepts
• Keep scope minimal - demonstrate ONE concept well

Documentation

• README.md follows readme-and-co:documentation-standards
• Include "How to Run" section with exact commands
• Document environment setup requirements
• Explain the Compact contract's purpose and circuits

Git Workflow

Commits

• Follow git-lovely:useful-commits skill for commit messages
• Commit and push after each completed task
• All work on feature branch, PR to main

Branch Naming

• Format: {feature-name} (provided by user)
• Example: counter-example, token-transfer

Phase Reviews (Mandatory)

After each implementation phase, run BOTH reviews:

1. Compact Code Review

Use compact-reviewer:compact-reviewer agent

Instructions: "You are reviewing an example dApp for the Midnight Network.
This project is intended to demonstrate concepts to developers learning Midnight.

Be pragmatic with suggestions:
- Focus on correctness and clarity over production concerns
- Flag anything that would confuse learners
- Flag bad practices that learners might copy
- Accept reasonable shortcuts that keep the example focused
- Ensure educational comments are accurate"

2. TypeScript Code Review

Use devs:code-reviewer agent

Instructions: "You are reviewing an example dApp for the Midnight Network.
This project is intended to demonstrate concepts to developers learning Midnight.

Be pragmatic with suggestions:
- Focus on correctness and clarity over production concerns
- Flag anything that would confuse learners
- Flag bad practices that learners might copy
- Accept reasonable shortcuts that keep the example focused
- Ensure educational comments are accurate"

All review issues must be addressed before proceeding to next phase.

Testing Requirements

• Include basic happy-path tests for main functionality
• Test contract circuits with TestContext
• Document how to run tests in README
• Tests must pass before PR can be marked ready

State Management

Plugin state is stored in .dapp-sdd/ directory (gitignored):

.dapp-sdd/
├── spec.md           # Expanded specification
├── plan.md           # Implementation plan
├── tasks.md          # Task list with checkboxes
└── pr-context.json   # PR metadata
