syzygy by adenineio: Claude Code mod code and design

What it does

Draws toasts in the terminal
Hooks *, prompt.submit, session.start
Keeps its own state between turns
Calls the network
Starts processes

Good points

Written in TypeScript
Has a desktop-specific branch
Handles errors
Writes no files

Code to start from

Two kinds: a starter modscode writes from the design above, and the lines of the mod's own code that draw it.

Starter (register.tsx)

import type { Register } from 'claude-code'

// Drawn like syzygy by adenineio (band, toast), as modscode read it from the mod's code:
// https://modscode.com/gallery/adenineio-syzygy/
// Written by modscode from that reading, not copied from the mod: use it as you like.
// Each value below stands for one the mod works out at run time; put in your own.
export const register: Register = on => {
}

The mod's own code

What its code shows

Read from the source at commit 35fd8b7be3d3 on 2026-10-06. The first group decides whether a mod is listed; the rest is for you to weigh. A later commit is not read until the next crawl.

Decides the listing: code you can check
Entry read	Every module hooks/hooks.json names was read.syzygy/hooks/hud.tsx
Parses	Every file parses as TypeScript or JavaScript.2 files parsed
All its code is in the mod	Every import is a file of the mod or the engine's own module; no packages, no require.all its code is in the mod
Readable	No minified lines, no eval or new Function, no import of a computed path, no encoded blobs.no minified code, no eval, no encoded blobs
Calls in the open	Network and programs are reached as $.http.fetch and $.process.run in place, never passed around.every call outside goes through $ in the open
For you to weigh before installing
Where it draws	The terminal, the desktop app, both, or nothing (hooks only: a guard or a prompt rewriter), as its code says. Shown, never a reason to leave a mod out.draws in the terminal only
Install line	Whether its repository's own .claude-plugin/marketplace.json lists it, so it installs from that marketplace with the lines on its page.its repository's .claude-plugin/marketplace.json does not list it: no install line to give
Programs on Windows	Whether every program it starts through $.process exists on Windows (tail, date, open, osascript, /usr/… do not).syzygy/hooks/hud.tsx:1077 find (not on Windows); syzygy/hooks/hud.tsx:1093 tail (not on Windows); syzygy/hooks/hud.tsx:1480 cat (not on Windows)
Network	Whether every fetch names its https host in the code.syzygy/hooks/hud.tsx:1510 fetch(relayUrl('/api/health')); syzygy/hooks/hud.tsx:1544 fetch(relayUrl('/api/health')); syzygy/hooks/hud.tsx:1803 fetch(relayUrl('/api/health'))
Programs	Whether every program it starts is named in the code and is not a shell, an interpreter or a network tool.syzygy/hooks/hud.tsx:1522 sh (a shell or interpreter); syzygy/hooks/hud.tsx:1649 sh (a shell or interpreter)
Reads and sends	Whether it both reads files or environment variables and reaches the network.reaches the network, but reads no files and no environment variables
Keys in the source	Whether the source holds what looks like an API key or a private key.no keys in the source
Licence	An open licence (MIT, Apache-2.0, BSD, ISC, Unlicense, 0BSD, CC0) with its text lets modscode show its code; otherwise the code is linked.Apache-2.0

This is a reading of the code text, not a security review: it does not run the mod, and it cannot see what a program the mod starts does. The check before installing is yours. How mods are chosen

Install it

Check it yourself before you install it. Mods run unsandboxed, with your permissions, and modscode does not vouch for what this code does. Read the code below (or run claude plugin validate . in its folder), weigh what it reaches, and install the commit you read.

Its repository's .claude-plugin/marketplace.json does not list it, so there is no install line to give. Read it as code, or follow its author's README.

Ask Claude about it

With the modscode connector added, Claude can read this design, what its code reaches and its code, and build on them. Ask it like this:
