## Description

Claude Usage Meter brings transparency to your AI workflow by showing your exact usage metrics directly inside the <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/cf6f55cbba6731f7030d49478c86cb1b6c503e9ea8cb3f1a019bd0e646726ebe/http%3A//Claude.ai" rel="nofollow">Claude.ai</a> chat interface. It helps you stay within limits and manage your context window without leaving the conversation.

<strong>Key Features:</strong>
1. <strong>Live Usage Bars:</strong> Displays two progress bars (Session and Weekly) at the bottom of the chat composer.
2. <strong>High Precision:</strong> Shows usage to the decimal point (e.g., 22.832%), sourced directly from the API stream.
3. <strong>Token Counter:</strong> Real-time calculation of conversation tokens with a 200k context window indicator.
4. <strong>Cache Timer:</strong> Shows exactly how long your conversation remains prompt-cached to save on usage limits.
5. <strong>Visual Alerts:</strong> Color-coded bars (Blue → Amber → Red) signal when you are approaching limits.
6. <strong>One-Click Refresh:</strong> Instantly sync data with Claude's servers.

<strong>How it works:</strong>
The extension reads usage data your browser already receives from Claude's servers. It intercepts the network stream to extract the hidden <code>message_limit</code> field. Token counting is performed locally using a bundled BPE tokenizer.

<strong>Privacy First:</strong>
1. Runs 100% locally in your browser.
2. No external server requests.
3. No data collection or analytics.
4. No conversation content ever leaves your machine.
