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

Read the context monitor state file to get the current tool call count:

~/.claude/sessions/{project-hash}/context-monitor-state.json

The project hash is a SHA-256 of CLAUDE_PROJECT_DIR (first 12 chars). If the state file doesn't exist, report "No context monitor data — hook may not be active."
