Per-session and consolidated token usage visibility in Claude Code

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Currently there is no way to see how many tokens were consumed in an individual Claude Code session, or across sessions in a consolidated view. When using /resume to pick a past session, there is no token metadata shown alongside it.

Proposed Solution

A simple toggle between "Session View" and "Summary View" within the Claude Code interface, similar to how many tools show per-request vs. aggregate
metrics.

Use Case Example

Add token usage visibility at two levels, with the ability to toggle between them:

1. Per-session view — when browsing or resuming a session, show input tokens, output tokens, and total tokens consumed for that session
2. Consolidated view — an aggregate summary across all sessions (daily/weekly/all-time) so users can understand their overall consumption pattern

Why this matters

• Helps users understand which types of tasks are token-intensive
• Enables prompt optimization — users can experiment and see the impact
• Helps manage context window bloat by making it visible rather than invisible
• Particularly useful for non-technical users who are new to AI-assisted development and learning to work efficiently with Claude Code
