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 session-prs by itkrt2y (band), as modscode read it from the mod's code:
// https://modscode.com/gallery/itkrt2y-session-prs/
// 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, Link } = $.ui.resolve(e)
    const length = '…'
    const url = '…'
    const repo = '…'
    const number = '…'
    return (
      <Box flexDirection="column">
        <Box>
          <Text dimColor>
            PRs this session (
            {length}
            {") "}
          </Text>
          <Button label="Hide" />
        </Box>
        <Box>
          <Text>
            {"• "}
          </Text>
          <Link href={`${url}`} label={`${repo}#${number}`} />
        </Box>
        <Box>
          <Text>
            {"• "}
          </Text>
          <Link href={`${url}`} label={`${repo}#${number}`} />
        </Box>
        <Box>
          <Text>
            {"• "}
          </Text>
          <Link href={`${url}`} label={`${repo}#${number}`} />
        </Box>
        {await next(e)}
      </Box>
    )
  })
}

What its code calls

Ask Claude…

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 b476fe863f8b 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.plugins/session-prs/hooks/session-prs.tsx
Parses	Every file parses as TypeScript or JavaScript.1 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 and the desktop app, the same in both
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.listed in its repository's .claude-plugin/marketplace.json: installs from there
Programs on Windows	Whether every program it starts through $.process exists on Windows (tail, date, open, osascript, /usr/… do not).runs no program a Windows PC lacks
Network	Whether every fetch names its https host in the code.no network
Programs	Whether every program it starts is named in the code and is not a shell, an interpreter or a network tool.git (reaches the network), gh (reaches the network)
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.MIT

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 itkrt2y/claude-plugins

/plugin install session-prs@itkrt2y-claude-plugins

This installs the marketplace's latest commit, which may not be the one read here (b476fe863f8b). Compare them before you install.

Ask Claude about it
