The Hook
The entire PasteDrop codebase was written in a single 21-minute sitting. Three commits, start to finish. Eight days later, it was live on the Mac App Store. No pivots, no stalled weekends, no half-finished branch sitting on a second monitor. Idea on a Sunday, approval the following Sunday.
This is the story of how that happened, and why it's repeatable.

What PasteDrop Does
PasteDrop
macOS 14+ menu-bar clipboard utility
PasteDrop lives in the menu bar, watches the clipboard, and offers one-click transformations based on what you just copied. Copy a URL, get encode, decode, and strip query params. Copy a hex color, get a rendered swatch plus RGB and HSL conversions. Copy JSON, get pretty-print and minify. Nothing leaves the device. No network calls, no telemetry, no data collection.
8 detected content types:
JSONURLhex coloremailcodenumberUUIDplain textEach type gets its own set of transforms, plus 5 universal ones that apply to any string. Thirty plus transforms in total, all offline, all instant.

Three commits. Twenty-one minutes. Then eight days of waiting for Apple.
This Wasn't a Lucky One-Off
A 21-minute codebase only lands clean when the groundwork is already in place. PasteDrop was the first app shipped through a deliberate system called ship-apps: a small, opinionated pipeline for going from an idea to an App Store listing without reinventing the boring parts every time.
The real product isn't PasteDrop. It's the pipeline. PasteDrop is the proof that the pipeline works.
The Five Ingredients
Everything below already existed before PasteDrop. That's the point. Each piece was built once, tuned on earlier experiments, and then composed for this release.
The scaffold skill
/ship-app
A Claude Code skill that copies a platform template, renames every AppTemplate reference, inits git, and verifies the build compiles. One command from zero to "it builds."
Platform templates
~/templates/macos-utility
Pre-wired Package.swift, CLAUDE.md, Sources/, entitlements, PrivacyInfo.xcprivacy. A macOS variant and an iOS variant, both ready to be copied into a new app.
XcodeGen contract
project.yml
Every app regenerates its Xcode project from a yaml file. No .xcodeproj merge conflicts, no drift between what’s in git and what’s on disk.
Standardized CLAUDE.md
Rules / Build / Conventions
A shared contract across every app: Swift 6 strict concurrency, App Sandbox, SwiftUI-first, SF Symbols, conventional commits. The 25-line spec that served as the entire design doc.
Shared ASC playbook
APP_STORE_CONNECT_GUIDE.md
One document at ~/ship-apps/ with launch order, screenshot specs, common settings, and the com.87n1 bundle prefix. Every app inherits the same launch runbook.
Composed together: scaffold skill + platform template + XcodeGen + standardized CLAUDE.md + shared ASC playbook = a repeatable idea-to-App-Store flow.
Technical Shape
The app itself is small on purpose. Every dependency, every line of Swift, every entry in the entitlements file was a conscious choice, not an accumulation of defaults.

Strict concurrency
All three dependencies are sindresorhus libraries: KeyboardShortcuts, Defaults, and LaunchAtLogin-Modern. The CoreLib module is a pure-Swift framework with no AppKit dependency, which keeps the 80-test suite fast and lets future apps in the pipeline reuse the same content-detection logic without pulling in the menu-bar UI layer.
PasteDrop is shipped. The pipeline is still running, with more apps moving through the same five ingredients behind it.
