/skills

Teach your AI what took Alex over a decade to learn.

Skills are install-once knowledge packs for Claude Code: every gotcha, crash pattern, and production workflow documented so your agent doesn't rediscover them at your expense. Built from real shipped apps — the same pipelines that put Unreal and Godot builds on TestFlight overnight. Premium skills live on Capafy; the open-source ones are a npx skills add away.

Live now

Purchasable today — they run in your own Claude, on your machine.

ue5-testflight

Live on Capafy

Ship Unreal Engine 5 projects to TestFlight — macOS, iOS, and visionOS.

The autonomous UE5 → TestFlight pipeline, packaged as a skill your own Claude runs. Cook, stage, sign, version-bump, upload, distribute — every gotcha from shipping real visionOS apps documented inside.

ios-testflight

Live on Capafy

Archive and upload iOS / visionOS / macOS Xcode projects to TestFlight via CLI.

The native-Xcode sibling: altool-free uploads, signing-identity sanity checks, build-number discipline, and the export-options matrix that actually works. Runs entirely in your own Claude.

In the pipeline

Authored, tested, and queued for release. Watch this space.

godot-visionos

Coming soon

Build Godot apps for Apple Vision Pro — flat-plane and full immersive.

Everything learned shipping Cascade Countdown: the build switcher, simulator input, hand tracking, and the silent-failure traps that cost device round-trips.

Free forever

Open source on GitHub — because the ecosystem rises together.

ue5-mcp

Free & open source

A field manual for AI agents driving Unreal Engine 5 through MCP.

Free and open source. Reflection gotchas, crash patterns, subsystem quirks — install it and your agent stops rediscovering UE's sharp edges every session.
