- 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)
import type { Register } from 'claude-code'
// Drawn like context-band by LilianSu (band), as modscode read it from the mod's code:
// https://modscode.com/gallery/ericjamie-context-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
on('ui.render', { component: 'AbovePrompt' }, async ($, e, next) => {
const { Box, Text, Button } = $.ui.resolve(e)

What its code shows
Read from the source at commit d33e252ce957 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 | |
|---|---|

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 is its marketplace. Add that marketplace (in the terminal with these commands, or in the desktop app's plugin settings) and install the mod from it:
/plugin marketplace add EricJamie/claude-code-mods/plugin install context-band@claude-code-modsThis installs the marketplace's latest commit, which may not be the one read here (d33e252ce957). Compare them before you install.
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:
