Context Window Indicator Plugin

Shows real-time context window usage percentage in the Agent Zero chat UI bar.

Features

• Displays current token usage as a percentage of the model's context window
• Color-coded indicator: green (ok), yellow (warning), orange (danger), red (critical)
• Visual progress bar alongside the percentage
• Tooltip with detailed token count, context length, model name, and percentage
• Auto-polls every 5 seconds to keep stats current
• Responsive design: hides progress bar on mobile, keeps percentage visible

Configuration

Edit default_config.yaml to customize thresholds:

Setting	Default	Description
warning_threshold	50	Percentage to show yellow warning
danger_threshold	75	Percentage to show orange danger
critical_threshold	90	Percentage to show red critical
show_bar	true	Show/hide the progress bar
poll_interval_seconds	5	How often to refresh stats

How It Works

1. Extension Hook: response_stream_end hook computes token stats after each agent response and caches them
2. API Endpoint: /plugins/context_indicator/context_stats serves cached or fresh stats per context
3. Alpine Store: Frontend store polls the API and provides reactive data
4. UI Badge: Rendered in chat-input-bottom-actions-end slot with color-coded display
