aparente

ambient-alerts

A Claude Code plugin for ambient light communication. Express states, respond to events, and build a shared visual language between you and Claude through smart lights.

Features

• State-based communication - Define what each state looks like (idle, thinking, completed, etc.)
• Gentle animations - Smooth color oscillations with configurable speed and range
• Automatic events - Lights respond to permission requests, tool completion, errors
• Volitional control - Claude can express states based on context and judgment
• Interview-based setup - Collaboratively design your light language through conversation
• Transitions - States can auto-transition (e.g., "completed" fades to "idle")
• Works with any smart light - Philips Hue (via OpenHue) or custom commands

Quick Start

# Add the marketplace (first time only)
/plugin marketplace add aparente/ambient-alerts

# Install the plugin
/plugin install ambient-alerts@aparente

# Or via CLI:
# claude plugin marketplace add aparente/ambient-alerts
# claude plugin install ambient-alerts@aparente

# Run interactive setup - just ask Claude:
# "Set up ambient alerts for my lights"

How It Works

States

Define what each state looks like in your config:

{
  "states": {
    "idle": { "color": "antique_white", "brightness": 40 },
    "thinking": { "color": "light_blue", "brightness": 60 },
    "completed": { "color": "pale_green", "brightness": 60 },
    "need_input": { "color": "gold", "brightness": 75 },
    "waiting": { "color": "lavender", "brightness": 50 },
    "error": { "color": "coral", "brightness": 70 }
  }
}

Automatic Events

Map system events to states:

{
  "events": {
    "PermissionRequest": "need_input",
    "PostToolUse.success": "completed",
    "PostToolUse.error": "error",
    "SessionStart": "idle",
    "SessionEnd": "off"
  }
}

Transitions

Define auto-transitions between states:

{
  "transitions": {
    "completed": {
      "duration_ms": 2000,
      "then": "idle"
    }
  }
}

Volitional Control

Claude can set states directly when appropriate:

{
  "volitional": {
    "enabled": true
  }
}

Installation

claude plugins install ambient-alerts@aparente

Setup

Interactive Setup (Recommended)

Just ask Claude:

Set up ambient alerts for my lights

Claude will guide you through:

1. Selecting your smart light system
2. Choosing which light to use
3. Interview 1: Automatic Events - What should happen on permission requests, completions, errors?
4. Interview 2: Volitional Presence - How should Claude express thinking, waiting, idle states?
5. Testing and fine-tuning until it feels right

Manual Setup

Create ~/.claude/ambient-alerts.json:

{
  "backend": "openhue",
  "light_name": "Pitcher",

  "states": {
    "idle": {
      "color": "antique_white",
      "brightness": 40,
      "description": "I'm here, all is well"
    },
    "thinking": {
      "color": "light_blue",
      "brightness": 60,
      "description": "Working on something"
    },
    "completed": {
      "color": "pale_green",
      "brightness": 60,
      "description": "Done!"
    },
    "need_input": {
      "color": "gold",
      "brightness": 75,
      "description": "When you have a moment..."
    },
    "waiting": {
      "color": "lavender",
      "brightness": 50,
      "description": "Ball's in your court, no rush"
    },
    "error": {
      "color": "coral",
      "brightness": 70,
      "description": "Something needs attention"
    },
    "off": {
      "description": "Light off"
    }
  },

  "events": {
    "PermissionRequest": "need_input",
    "PostToolUse.success": "completed",
    "PostToolUse.error": "error",
    "SessionStart": "idle",
    "SessionEnd": "off"
  },

  "transitions": {
    "completed": {
      "duration_ms": 2000,
      "then": "idle"
    }
  },

  "volitional": {
    "enabled": true
  }
}

Direct State Control

Set states directly via the script:

# Set to thinking state
~/.claude/plugins/cache/aparente/ambient-alerts/1.0.0/scripts/set-state.sh thinking

# Set to idle
~/.claude/plugins/cache/aparente/ambient-alerts/1.0.0/scripts/set-state.sh idle

# Turn off
~/.claude/plugins/cache/aparente/ambient-alerts/1.0.0/scripts/set-state.sh off

Custom Backend

For non-Hue systems (LIFX, Govee, Home Assistant, etc.):

{
  "backend": "custom",
  "custom_commands": {
    "set": "hass-cli light set office --color {color} --brightness {brightness}",
    "idle": "hass-cli light set office --color white --brightness 40",
    "thinking": "hass-cli light set office --color blue --brightness 60"
  }
}
