context-bar

The context-bar skill provides developers working within the Claude Code environment with a vital observability tool: a real-time, color-coded visual representation of their current context window consumption. By integrating directly into the command-line statusline, it eliminates the need for guesswork regarding token limits, allowing developers to monitor their resource footprint continuously without interrupting their workflow. The visualization uses a clear threshold-based system—green for efficient usage (under 50%), amber for moderate usage (50-79%), and red for critical levels (80% and above)—enabling proactive management of long-running sessions, complex debugging tasks, or large codebase interactions.

• Real-time visualization of token usage percentage directly in the Claude Code statusline interface.

• Color-coded alerts to signal potential context overflow risks before they occur, helping to prevent truncated outputs or performance degradation.

• On-demand context status checks via the /context-bar slash command, providing quick snapshots without affecting terminal history.

• Seamless integration with existing Claude Code settings for project-level or user-level configuration.

• Supports observability of additional session metadata, including active git branches and current directory status.

• This tool is specifically designed for developers, software engineers, and AI-agent operators who frequently manage large-scale coding projects.

• Users should ensure their environment is configured with the provided bash script to ensure the statusline updates accurately after every interaction.

• It is a lightweight monitoring utility that relies on internal Claude Code state tracking (context_window.used_percentage) for maximum accuracy.

• The skill functions as a status plugin; it is not intended for heavy data manipulation but rather as an essential diagnostic overlay for maintaining session health and avoiding context-window-related errors during intense development cycles.
