/debug

Toggles Debug mode, built for reproducing and narrowing down bugs.

/debug toggles Debug mode, or submits a prompt directly in Debug mode. Reproduction-step cards are shown with their own (red) accent in Debug mode, so the active mode stays clear.

✅ WHEN TO USE IT?

Narrow down a specific bug

/debug Login fails after a password reset

Work through reproduction steps systematically

/debug — activate the mode before pasting a bug report with a stack trace

⛔ WHEN NOT TO?

A new feature should be built directly

Debug mode is built for bug-finding and narrowing, not new development.

Better: Use normal agent mode or /plan for feature work

The bug is already clearly located

If the cause and the fix are already clear, Debug mode adds no value.

Better: Ask for the fix directly in agent mode
