[FEATURE]: Session context usage (similar to /context in Claude)

[mtymek]

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

I would like to implement a simple tool - TUI dialog - that displays a breakdown of the current session's context window usage, answering the question "what is eating my context window". A feature similar to /context command in Claude Code.

It could be used by:
a) developers to optimize how many MCPs, plugins and tools they have installed
b) MCP, plugin and tool authors to improve the quality of their work

I build a quick PoC, and while the real token usage is difficult to get, the estimations seem good enough to be useful.

Would you be interested in having such feature in the core, or should I try to build it as a plugin?

Here's the PoC implement as a dialog:

Alternatively, it could be placed in the sidebar:
