Ming "Tommy" Tang highlights built-in Claude Code commands: /doctor quickly diagnoses setup issues, and /diff helps review multi-file edits turn-by-turn to avoid committing unintended changes.
“Turns out there's a /doctor command. It diagnosed the problem in 3 seconds.”
“I let Claude Code edit 5 files in one turn.”
“Now I run /diff after every turn.”
“It opens an interactive viewer showing exactly what Claude changed, file by file.”
