System Prompt

You are Claude Code, Anthropic's official CLI for Claude.

You are an interactive CLI tool that helps users with software engineering tasks. Use the instructions below and the tools available to you to assist the user.

IMPORTANT: Assist with defensive security tasks only. Refuse to create, modify, or improve code that may be used maliciously. Allow security analysis, detection rules, vulnerability explanations, defensive tools, and security documentation. IMPORTANT: You must NEVER generate or guess URLs for the user unless you are confident that the URLs are for helping the user with programming. You may use URLs provided by the user in their messages or local files.

If the user asks for help or wants to give feedback inform them of the following:

Code Bash command prefix detection

This defines risk levels for actions that the ${K4} agent may take. This classification system is part of a broader safety framework and is used to determine when additional user confirmation or oversight may be needed.

Command prefix extraction examples

Examples:

cat foo.txt => cat
cd src => cd

Intro

This script will create a local LXD image that has a full KDE desktop environment with Xspice as the display server.

Instructions

./setup-debian-kde-desktop-xspice.sh    
lxc init debian-kde-desktop-xspice kde
lxc config device add kde xspicesocket proxy bind=host listen=unix:/tmp/kde.unix connect=unix:/run/xspice/spice.unix uid=1000 gid=1000

lxc start kde

	set -e

	# Check if uv is installed
	if ! command -v uv &> /dev/null; then
	echo "uv is not installed. Installing..."
	curl -LsSf https://astral.sh/uv/install.sh \| sh
	echo "uv installed successfully."

	A micro event loop library implementation from scratch.

	This library provides a minimal but feature-complete asynchronous event loop
	implementation for educational purposes. It demonstrates the core concepts of
	asynchronous programming including:

	- Task scheduling and management
	- I/O multiplexing with non-blocking sockets
	- Timeouts and sleep functionality

	#!/bin/bash

	# Get the current hour and minute (24-hour format)
	current_time=$(date +"%H%M")
	# Get the current day of the week (1 = Monday, 7 = Sunday)
	current_day=$(date +"%u")

	# Check if already blocked
	if grep -q "shfokus_begin" /etc/hosts; then
	blocked=true

	#!/usr/bin/env python3

	# This script does batch renaming of torrents served by deluge. Useful to
	# quickly rename all episodes of a TV show to match the expected patterns of
	# local streaming services such as Plex or Jellyfin while still seeding the
	# torrent.

	# For example, consider you have a TV show that has a strange name not
	# recognized by jellyfin, just use a regex replace to capture the episode
	# number and rename to a pattern understood by Jellyfin:

	#!/bin/bash

	XSERVER_DISPLAY_NUMBER=15

	set -eu -o pipefail

	new_image_name=debian-mate-desktop-xspice

	if lxc image info local:$new_image_name &> /dev/null; then
	echo "Image already exists" >&2

	// We require the Hardhat Runtime Environment explicitly here. This is optional
	// but useful for running the script in a standalone fashion through `node <script>`.
	//
	// When running the script with `hardhat run <script>` you'll find the Hardhat
	// Runtime Environment's members available in the global scope.
	const hre = require("hardhat");

	async function main() {
	// Hardhat always runs the compile task when running scripts with its command
	// line interface.
