| 1 | # Context Window |
| 2 | |
| 3 | The bundled Context Window plugin adds a compact usage ring beside the chat's |
| 4 | model and agent selectors. Its popover shows token counts and full-window |
| 5 | percentages for Messages, System tools, Skills, MCP tools, System prompt, |
| 6 | Extras, and Free space. |
| 7 | |
| 8 | Older chats gain the detailed breakdown after their next model turn. Mobile and |
| 9 | desktop visibility can be changed under **Settings > Interface**. |
| 10 | |
| 11 | When a model provider reports usage, the popover shows price, cache-hit rate, |
| 12 | and input/output tokens. Unreported price and cache data are omitted. The |
| 13 | context breakdown does not guess model-specific image token costs. |
| 14 | |
| 15 | For streamed OpenRouter chat calls, the plugin requests and drains LiteLLM's |
| 16 | terminal usage event after Agent Zero has accepted the response. Price remains |
| 17 | hidden when LiteLLM does not report a cost or map the selected model. |
