FAQPage Schema
How do I monitor Claude Code context window token usage in real-time?▼

You can monitor Claude Code context window token usage by running the context-bar command, which calculates token percentages from JSONL transcript data and displays a visual progress bar to track active session consumption.

Can I display a token usage progress bar in the Claude Code statusline?▼

Yes, you can integrate the context bar directly into the Claude Code statusline. This configuration provides immediate visual feedback on your context window usage without interrupting your active coding workflow.

How does the color-coded context bar indicate different token usage levels?▼

The color-coded context bar uses green, amber, and red to indicate low, medium, and high context usage respectively, helping you quickly assess when you are approaching token limits during a coding session.

What is the best way to prevent unexpected token limits when working with large codebases in Claude Code?▼

The best way to prevent unexpected token limits is to monitor context window usage with a visual progress bar, allowing you to see how much of your available context is being consumed by your current session.

Does the context bar require parsing JSONL transcript data to calculate token percentages?▼

Yes, the context bar relies on parsing JSONL transcript data to calculate token percentages against a defined context window, ensuring accurate monitoring of your current Claude Code session consumption.
