FAQPage Schema
How do I check remaining context window usage on a mobile phone?▼

Check context window usage by invoking the /window command, which aggregates active session JSONL logs and token counts to compute and emit a compact, phone-friendly status line reporting live usage.

What is a context window and when do I need to monitor it?▼

A context window is the maximum token capacity a session supports. Monitor context window usage to assess whether to continue a session before hitting the 1M token limit, preventing unexpected truncation.

Does the context window check work on small screens without overwhelming the display?▼

Yes, the context window check works on small screens by design. It computes live token usage and delivers the result as a single line, ensuring the output remains concise and readable on mobile phones.

How to compute live context token counts from session logs?▼

Compute live context token counts from session logs by triggering the /window command, which aggregates the active session's JSONL logs to calculate current token usage and reports it as a single status line.

When should I avoid relying on a single-line context summary?▼

Avoid relying on a single-line context summary when you need detailed token breakdowns or historical usage trends, as this approach intentionally provides only a compact, live status line for quick checks on mobile screens.
