Quack — Rubber Duck Debugger 🦆

The duck never answers your bug. It only asks the questions that make you find it.

• Click the 🦆 in the status bar (or Ctrl+Alt+Q / Cmd+Alt+Q) to summon the duck.
• Select code → right-click → Quack: Explain This to the Duck.
• The duck reads your selection, the active file's real errors, and the language — and asks sharper questions for it. Everything stays on your machine: no network, no telemetry.

Five personalities (quack.mode): socratic, senior, savage, zen, chaos.

Part of the quack monorepo — same engine and question dataset as the CLI: npx quack.
