[Feature] No per-surface activity log for subscription usage

Summary

Claude subscription plans (Max) have no per-surface breakdown of activity.
There is no log showing which interface (Claude Code, claude.ai chat, Claude
Design, API via subscription, etc.) consumed usage at what time.

Impact

• Cannot audit unexpected quota consumption across surfaces
• When a rate limit hits, there is no way to determine which surface caused it
• Claude Design was silently merged into the shared Max quota pool on ~2026-05-28

with no announcement; without a per-surface log, users had no way to detect this

• Contrast: API console (console.anthropic.com) shows per-model token usage with

timestamps for API key users

What would help

A usage log at claude.ai/settings/usage showing:

• Timestamp
• Surface (Claude Code / claude.ai / Design / etc.)
• Model used
• Approximate token/usage amount

Even a rolling 7-day history would be sufficient for the primary use case
(diagnosing unexpected rate limits).

per-surface historical log, not in-session metrics)

Environment

• Claude Code v2.1.170, macOS 15.x
• Claude Max (5x) subscription
• Multiple surfaces in use: Claude Code, claude.ai, Claude Design
