Feature request: show context used and remaining per agent

[stefanpieter]

Feature request

Please show context used / context remaining for each agent in the chat UI.

What I want

In multi-agent / delegated workflows, I want visibility into how much context window each agent is using and how much remains.

Examples of useful information:

• Lead: context used / remaining
• Reviewer: context used / remaining
• Validator: context used / remaining
• Sub-agent X: context used / remaining

Even approximate values are useful if exact numbers are not always available.

Why this matters

This would help a lot when working with long-running or orchestration-heavy chats, because I want to know:

• which agent is close to context exhaustion
• whether compression/summarization is likely soon
• whether a quiet / degraded response is related to context pressure
• how healthy each agent session is over time

Suggested UI options

Possible implementations:

• small per-agent context badge
• hover metadata showing used / remaining / total window
• session diagnostics panel for the active conversation
• timeline/analytics view that includes context pressure

Scope

This request is specifically about per-agent context visibility, not only a global total for the whole chat.
