cache-keeper

Context, quota and prompt-cache meters above the prompt; while the session is idle on a 1-hour cache, keeps it alive and compacts before it lapses, holding off system sleep meanwhile (Linux, Windows, macOS).

Code you can checkTerminal + desktopPaneBandStatus lineBoxButtonText

What it does

  • Draws a band above the prompt, a pane
  • Hooks prompt.submit, session.compact, session.end, session.measure and 4 more
  • 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 cache-keeper by oioi555 (pane, band, status), as modscode read it from the mod's code:
// https://modscode.com/gallery/oioi555-cache-keeper/
// 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

What its code calls

The design, read from code

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 4c285053da49 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 readEvery module hooks/hooks.json names was read.plugins/cache-keeper/hooks/register.tsx
ParsesEvery file parses as TypeScript or JavaScript.3 files parsed
All its code is in the modEvery import is a file of the mod or the engine's own module; no packages, no require.all its code is in the mod
ReadableNo 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 openNetwork 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 drawsThe 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 lineWhether 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 WindowsWhether every program it starts through $.process exists on Windows (tail, date, open, osascript, /usr/… do not).runs no program a Windows PC lacks
NetworkWhether every fetch names its https host in the code.no network
ProgramsWhether every program it starts is named in the code and is not a shell, an interpreter or a network tool.plugins/cache-keeper/hooks/register.tsx:277 a program named at run time
Reads and sendsWhether it both reads files or environment variables and reaches the network.reaches no network
Keys in the sourceWhether the source holds what looks like an API key or a private key.no keys in the source
LicenceAn 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 oioi555/claude-code-mods
/plugin install cache-keeper@oioi555

This installs the marketplace's latest commit, which may not be the one read here (4c285053da49). 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:

Read the modscode design "oioi555-cache-keeper" with its code and make me a pane like it
