// General hints on defining types with constraints or invariants
// 
// Just as in C#, use a private constructor 
// and expose "factory" methods that enforce the constraints
//
// In F#, only classes can have private constructors with public members. 
//
// If you want to use the record and DU types, the whole type becomes
// private, which means that you also need to provide:
// * a constructor function ("create").

Multi-level arg parse

Shows how to structure a python app using arg parse that goes down many levels.

The "trick" is to

• add a subparsers S1[]
• add parsers P1[] to your subparser S1[x]
• add a new set of subparsers S2[] to one of those parsers P1[x]

Technical Documentation Template

First of all, you need to understand you are not writing documentation for you, nor for your current team. You are writing documentation for the future developers that were not there when you first wrote this code. Worst of it, they might think it is bad code for many reasons and won’t understand why you wrote this way.

Verified Spec-Driven Development (VSDD)

The Fusion: VDD × TDD × SDD for AI-Native Engineering

Overview

Verified Spec-Driven Development (VSDD) is a unified software engineering methodology that fuses three proven paradigms into a single AI-orchestrated pipeline:

• Spec-Driven Development (SDD): Define the contract before writing a single line of implementation. Specs are the source of truth.
• Test-Driven Development (TDD): Tests are written before code. Red → Green → Refactor. No code exists without a failing test that demanded it.
