git-sync-band
A band above the prompt with branch, ahead/behind, changed files and last push; pulls before your prompt when it is safe; Pull, Files and Commit & push buttons that run git without a model turn.
Code you can checkTerminal + desktopBandToastBoxButtonSvgText
What it does
- Draws a band above the prompt, toasts
- Watches tool calls
- Hooks prompt.submit, session.start, turn.complete
- Keeps its own state between turns
- Starts processes
Good points
- No network calls
- Written in TypeScript
- Has a desktop-specific branch
- Handles errors
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)
register.tsx
import type { Register } from 'claude-code'
// Drawn like git-sync-band by Mohab Yasser (band, toast), as modscode read it from the mod's code:
// https://modscode.com/gallery/mohabyasser2-git-sync-band/
// 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 band above the prompt; what else goes there is drawn under it

Drawn from the mod's source at the commit read, not from a run: a list is drawn three times, a condition takes its first branch that draws in the desktop app, and a value only the run time knows is shown as a made-up sample (dotted underline) or left out. Colours and type are this site's.
What its code shows
Read from the source at commit 6732b3bf4d59 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.git-sync-band/hooks/register.tsx |

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:
Read the modscode design "mohabyasser2-git-sync-band" with its code and make me a pane like itSearch them from Claude: the MCP connector
