# 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)
