Architect

Design before implementing. Sketch types, function signatures, class shapes, and module boundaries with not implemented bodies and pseudocode. Synthesize across multiple model perspectives, then fill in code against the chosen sketch. If implementation proves the sketch wrong, throw it out and redesign.

Start

Open a todolist with one entry per phase before starting. Autonomous mode without checkpoints needs the list to show phase position and keep phases from silently disappearing.

Phase A: Ground the problem

Build a real mental model of every system the new code touches. Run the explore skill over the relevant subsystems. Use critique mode when existing structure is the constraint or the design must push back on it.
