diagnose

When NOT to use this

This skill diagnoses the 5dive agent runtime — auth state, service health, disk, memory, recent CLI errors, skill integrity — on the VM the agent runs on.

It is not the handler for a failed command in ordinary work. A build that breaks, a test that goes red, a script that exits non-zero, a compiler error, a network call that 404s: debug those in place. Reach for diagnose only when the evidence points at the runtime itself — the agent cannot authenticate, 5dive commands fail systemically, a service is down, the box is out of disk or memory, or installed skills are missing or corrupt.

This skill turns your agent into its own first-line support. Instead of forwarding "something's wrong" messages to a human, the agent inspects the VM, identifies the root cause, and either fixes it or reports a precise diagnosis.
