The Software Factory Playbook — Dex Horthy's 4-gate workflow as a skill

A Claude Code Agent Skill built from Dex Horthy's (HumanLayer) playbook on David Ondrej's podcast.

"Once the model has written thousands of lines of code, it is harder to change. The sessions that generate design docs are context-light — you get the most model intelligence when you do the hard thinking early."

By default, agents build horizontally: all the backend, then all the frontend, then a 2,000-line diff lands in your lap and reviewing it is your problem. This skill flips that. Every decision that matters gets made before the code exists — where changing your mind costs a sentence, not a rewrite.

What it does

Project Requirements Document: The Urlist Website

The following table outlines the detailed functional requirements of The Urlist website.

Requirement ID	Description	User Story	Expected Behavior/Outcome
FR001	Creating a New URL List	As a user, I want to be able to start a new, empty list so I can begin adding URLs.	The system should provide a clear way for the user to initiate the creation of a new list, potentially presenting an empty list view or an "add new list" button.
FR002	A

Pakistan CNIC Number Validator

RegEx for validating CNIC numbers of Pakistan

CNIC stands for Computerized National Identiry Card. There are two ways we can actually write CNIC numbers:

12345-1234567-1
1234512345671

One with dashes and one without dashes but not mixed with other.

Only Allow Dashes

Pakistan Mobile Number Validator

RegEx for validating mobile numbers of Pakistan. To change it to work for your country just change 92 and 3 with your country code. Also you can change length of numbers by changing last {9}

^((\+92)?(0092)?(92)?(0)?)(3)([0-9]{9})$/gm

Test it online on RegExr or RegEx101

Explanation:

There are three groups:

	import { StorageSerializers } from '@vueuse/core';

	export default async <T>(url: string) => {
	// Use sessionStorage to cache the lesson data
	const cached = useSessionStorage<T>(url, null, {
	// By passing null as default it can't automatically
	// determine which serializer to use
	serializer: StorageSerializers.object,
	});

	addEventListener('fetch', (event) => {
	event.respondWith(handle(event.request))
	})

	// use secrets
	const client_id = CLIENT_ID
	const client_secret = CLIENT_SECRET
	const redirect_uri = 'https://url.workers.dev'
	const scope = 'repo,user'
