Usage limits, seen and continued
Three small bars above the context gauge show how much of your plan's windows is used: Claude's 5-hour session, weekly and Opus windows; Codex's 5-hour and weekly limits. Hover for the reset time. When the agent refuses a turn for lack of credit, a no-entry bar counts down to the reset; Continue resends the prompt, Auto-continue does it for you the moment credit is back.
Things you can do with it
See the wall before you hit it
The session bar is orange and resets in 48 minutes. Give the agent the small task now and the big one after the reset.
Let the night shift finish
The weekly window ran out at 23:10. Tick Auto-continue and go to bed; the turn continues when the window resets, and the queue plays on after it.
Know it is a limit, not a bug
The session is not in error. The red bar says the agent refused for lack of credit and when it will be back, with what the agent said on hover.
Pick the model that still has room
The Opus window is full but Sonnet's is not. Switch the model picker and continue.
How it works
For Claude Code the figures come with the model calls the agent makes, so Inspect LLM must be on (it is by default) and they refresh with the first call of each turn; for Codex they are read after each turn. Devin does not report its ACUs to Sessionboxer and Cursor does not report its usage either, so their bars are hatched.
When a window is used up (You've hit your session limit, Codex's usage limit, Cursor's usage limit, Devin's Quota exhausted), the refused prompt is kept. Continue sends it again, or asks the agent to continue where it left off. Auto-continue asks the agent a one-line question every 10 seconds once the reset is due and continues the turn the moment it answers.

Claude Code's /usage and Codex's /status show plan usage in the terminal on request. Hosted agents bill on their own account and show usage in their dashboards; there is no subscription window to run into mid-turn, and no need to resume one. Sessionboxer keeps the windows in view and picks the turn up by itself when they reset.
