[FEATURE]: Show the model's context window limit in the TUI (footer and sidebar) #42929
Description
Feature hasn't been suggested before.
- I have verified this feature I'm about to request hasn't been suggested before.
Describe the enhancement you want to request
The TUI usage counter shows the current session's token usage with a percentage, e.g. 30.0K (15%), but there is no visible reference for what that percentage is relative to — the model's context window limit is not shown anywhere in the TUI.
Without the limit, it's hard to judge how much room is left in the context window, which matters in long sessions where compaction kicks in near the limit.
Requested: show the model's context window limit alongside the token count in both places the usage counter appears:
- Input bar / prompt counter:
30.0K / 200K (15%)instead of30.0K (15%). - Sidebar context panel:
30,000 / 200,000 tokensinstead of30,000 tokens.
The limit comes from the active model's limit.context (models.dev / provider config). Models without a known limit should keep the current behavior (token count + percentage only).
Related: builds on #13003 (display token usage in the TUI — its status-bar option already sketches Tokens: 19.9K/1M). #33745 asked for the utilization percentage, which the TUI now already shows; this request is specifically about the absolute context window limit.

This adds exactly what's requested — an OpenTUI sidebar showing the model's
context window, current usage, and a per-category breakdown, live per session.
I've built it as a plugin — opencode-context-indicator. Still in a testing
stage; with your help and feedback we can make it better together.

Thanks for the suggestion, @Haltarys! You're asking for the TUI to show the active model's context window limit next to the token count:
30.0K / 200K (15%)in the prompt footer and30,000 / 200,000 tokensin the sidebar context panel. Models without a known limit would keep the current format.The percentage is already calculated from the model's
limit.context, but the limit itself isn't shown anywhere. Maintainers will consider this.Related issues:
