claude-keeper has moved to https://github.com/nevyn/claude-keeper, which has signed and notarized releases that install without a compiler. This gist no longer holds the code.

api-tour: a guided tour of Claude Code mods

A Claude Code mod that exercises the whole mods API, so you can see what a mod can draw and do instead of reading about it. Run /tour and step through eight tabs: every drawing element, hover effects, form controls, a 10 fps pixel animation, a Julia set drawn as an image, a tiny paint program running on the drawing thread, and about twenty buttons that each call a different part of the engine.

Image tab in Ghostty: a Julia set from raw RGBA bytes, 5 fps	Raster tab in Ghostty: a plasma of half-block cells, 10 fps

| Raster tab on desktop: the Svg fallback, animated | Engine tab: one button per

#!/usr/bin/env bash
# coolify — a bash CLI wrapper for Coolify's REST API
#
# Why: the Coolify API has enough sharp edges (field name asymmetries, multiple
# create-app endpoints, JSON payload gymnastics) that wrapping it pays for itself
# after a handful of deployments. This script is what I use on my own Coolify
# instance, with Claude Code agents driving it via SSH.

GH Actions workflow for Mac and Vision Pro

This is taken from my app koja.works, as an attempt to get full notarized + appstore builds made in a single CI workflow so that I can keep track of all moving parts, without involving Fastlane (which in my experience breaks way too often due to system rubies etc).

Builds for both Mac and visionOS, and the vision file is probably easily extensible to iOS as well (maybe with matrix builds?)

I'm using a self-hosted Mac mini on my desktop, which is why I have to fiddle with PATH etc. I'm doing this because I require metal support during build, which Xcode Cloud does not support.
