Why it matters

It is one of 196 sightings filed under Productivity on Agent Sightings (number 133 by interest), and one of 164 involving Claude Code.

Help me test local web apps and fix errors in one session. Break it into steps, show your work, and wait for confirmation before anything irreversible, paid, or outbound.
