Feature Request: Status Bar Access for Claude Code

Provide Claude Code with the ability to access and update a status bar in the UI.

Motivation:
Claude Code currently lacks any way to display persistent, non-intrusive, task-specific status information to users. Adding status bar access would enable various helpful features without cluttering the main conversation area.

Proposed Implementation:
Create an API that allows Claude Code to:

• Write to and update text in a status bar
• Control basic formatting or sections within the status bar
• Clear or reset status bar content when appropriate

Use Cases:

• Tracking progress in multi-step workflows (e.g., "Step 3 of 7")
• Displaying relevant metrics (execution time, memory usage, etc.)
• Showing contextual information based on current task
• Providing ambient awareness of background processes
• Indicating the current mode or state of operation

It would give Claude Code more flexibility, enabling more sophisticated interactions while keeping the main conversation area focused on primary content.
