Context Status: Session Health Check

On-demand diagnostic showing context usage, preservation state, and open work items. Fast and lightweight — no vault queries.

What to Check

1. Context Usage Estimate (host-aware)

Use the active client's native context meter when it is exposed. A client adapter may provide a tool-call counter, but it is optional and must never be treated as shared memory. If no meter is available, report SKIPPED (client does not expose context telemetry); do not guess a percentage from conversation length.

Calculate:

• Tool calls so far
• Estimated percentage (calls / 150)
• Which thresholds have fired (from the fired array)
• Time since last warning
