Problem Statement

## Problem

Users on Claude for Teams plans have no way to view their own token consumption or usage history.

| Command | Result |
|---------|--------|
| /usage | _"Only available for subscription plans"_ — misleading for paid team users |
| /cost | _"You are currently using your subscription to power your Claude Code usage"_ — no actionable data |

## Expected Behavior

Individual users should be able to see:

| Metric | Description |
|--------|-------------|
| Session usage | Token consumption for the current session |
| Monthly usage | Cumulative token consumption for the current month |
| Usage history | Historical trends over time |

## Why This Matters

| Reason | Details |
|--------|---------|
| Rate limit awareness | No way to know you're approaching limits before hitting them |
| Productivity insights | Usage patterns help users work more efficiently |
| Regulated environments | In GxP / FDA 21 CFR Part 11 contexts, auditability is a compliance expectation |
| UX parity | API pay-as-you-go users get _better_ observability than paid subscription users |

Proposed Solution

## Suggested Solution

Re-enable /usage or /cost for team plan users with session and monthly token counts, or add a personal usage view under account settings at
claude.ai.
