🔥 Claude Power Mode

GPU-accelerated particle explosions, combo counter, screen shake, and fire effects for Claude Code — powered by Swift/SpriteKit.

What Is This?

A Claude Code plugin that renders real-time visual effects as a transparent overlay on your screen while Claude edits your code:

• 🎆 Particle Explosions — 8 GPU-accelerated presets (rightburst, stars, explosion, fountain, shockwave, emoji, disintegrate, fire) with bloom, additive blending, and physics fields
• 🔢 Combo Counter — Cinematic HUD tracking consecutive edits with 5 escalating levels, glow aura, scale-pop animations, and exclamation fly-ins
• 📳 Screen Shake — Camera-based shake with damped spring return, CIMotionBlur, and bloom flash on impact
• 🔥 Fire Wall — Multi-layer emitter fire (ember + flame + smoke) rising from the screen bottom at high combo levels

Every edit Claude makes triggers particle bursts. Chain edits fast enough and the combo escalates — bigger effects, screen shake, and eventually a wall of fire 🔥

How It Works

Claude Code Hook Events → Shell Script → Unix Socket → Swift/SpriteKit Overlay

1. Claude Code fires lifecycle hooks (PostToolUse, UserPromptSubmit, Stop)
2. Hook scripts transform events and send JSON over a Unix domain socket
3. A native macOS Swift app renders GPU-accelerated effects in a transparent, click-through overlay window
4. Effects scale with combo level — the faster Claude codes, the more spectacular it gets

Prerequisites

• macOS 13+ (Ventura or later)
• Swift 5.9+ (included with Xcode 15+ or Xcode Command Line Tools)
• Claude Code (with plugin support)

Installation

Quick Install

git clone https://github.com/your-org/claude-plugin-power-mode.git
cd claude-plugin-power-mode
./scripts/install.sh

Manual Install

# 1. Build the native overlay
cd native/macos && swift build -c release && cd ../..

# 2. Install as a Claude Code plugin
claude --plugin-dir /path/to/claude-plugin-power-mode

Verify Installation

# Start the overlay manually
./scripts/start.sh

# Send a test event
echo '{"event":"edit","tool":"Edit","file_path":"test.swift","timestamp":0}' | nc -U /tmp/claude-power-mode.sock

# Stop the overlay
./scripts/stop.sh

Usage

Once installed as a Claude Code plugin, Power Mode activates automatically. The overlay starts when you begin a Claude session and effects trigger on every file edit.

Slash Commands

Command	Description
/power-mode:powermode	Toggle power mode on/off
/power-mode:powermode on	Enable power mode
/power-mode:powermode off	Disable power mode

/power-mode:effects <preset>	Switch particle preset

Particle Presets

Preset	Description
rightburst	Arrow burst to the right with motion-blur trails (default)
stars	Twinkling stars with CIBloom glow halos
explosion	Radial burst with physics field and secondary debris
fountain	Parabolic arc with gravity simulation
shockwave	Expanding ring with animated radius
emoji	Full-color emoji with rotation and scale bounce

fire	Volumetric fire with layered emitters

Combo Levels

Level	Threshold	Color	Effects
1	10 edits	🟢 Green	Particles
2	25 edits	🔵 Cyan	Particles + Screen Shake
3	50 edits	🩷 Pink	Particles + Shake + Fire Wall
4	100 edits	🟣 Purple	All effects intensified
5	200 edits	🔴 Red	Maximum intensity

The combo resets after 3 seconds of inactivity.
