Description
Describe the bug
The model details display can overstate total context if it derives context by adding max_prompt_tokens and max_output_tokens. These are independent maxima and their sum may exceed max_context_window_tokens.
Affected version
1.0.81
Steps to reproduce the behavior
- Return synthetic model metadata with
max_prompt_tokens: 100000,max_output_tokens: 20000, andmax_context_window_tokens: 100000. - Open the CLI model details display.
- Check whether it reports 120,000 tokens instead of the declared 100,000-token context window.
Expected behavior
Display max_context_window_tokens as the total context window. Treat prompt and output limits as independent maxima rather than values whose sum defines context.
Additional context
The Copilot SDK/runtime preserves the independent context value, so this appears limited to CLI presentation.

Research direction
Start at the CLI model details display and trace how synthetic model metadata is formatted. Reproduce with max_prompt_tokens 100000, max_output_tokens 20000, and max_context_window_tokens 100000; done means the display reports the declared 100000-token context window while keeping prompt and output limits independent.
