Mobile surfaces show no context-usage indicator — users can't see long-session degradation coming
Summary
When driving a Claude Code session from a phone (claude.ai on mobile / remote-session clients), there is no visible indicator of context usage or session length. The terminal statusline exposes context percentage; mobile surfaces expose nothing.
Why it matters
I ran one session continuously for ~2 days, mostly from mobile. Late in the session the assistant's error rate rose in a specific way — confidently mis-remembered timelines, decisions replayed from summarized rather than actual history — i.e. ordinary context-compaction degradation. From the phone there was no signal whatsoever that the session was deep into compaction territory. The model itself eventually diagnosed it when challenged, but a user shouldn't need to infer this from the assistant getting things wrong.
Request
- Show context usage (even a coarse meter or percentage) on mobile/web session views, as the terminal statusline does.
- Consider an explicit in-conversation notice when heavy compaction has occurred, so users know recall of earlier events is now summarized.
- Expose context usage via an API/status field so third-party remote clients can render it too.
