A support-safe cmux health report with clear fixes.
terminal diagnostics
Collects and interprets support-safe cmux diagnostics for hooks, settings, sessions, notifications, and CLI health.
When to use it
Use when cmux behavior is failing or the user requests a health check, doctor report, or support-safe debug summary.
Give it a cmux problem or health-check request; it returns a read-only diagnostic report and interpretation.
