gsd-sketch

<objective> Explore design directions through throwaway HTML mockups before committing to implementation. Each sketch produces 2-3 variants for comparison. Sketches live in `.planning/sketches/` and integrate with GSD commit patterns, state tracking, and handoff workflows. Loads spike findings to ground mockups in real data shapes and validated interaction patterns.

• Idea mode (default) — describe a design idea to sketch
• Frontier mode (no argument or "frontier") — analyzes existing sketch landscape and proposes consistency and frontier sketches

<context> Design idea: $ARGUMENTS

• --quick

  — Skip mood/direction intake, jump straight to decomposition and building. Use when the design direction is already clear.

• --wrap-up

  — Package sketch design findings into a persistent project skill for future build conversations. Runs the sketch-wrap-up workflow. </context>

<process> Parse the first token of $ARGUMENTS: - If it is `--wrap-up`: strip the flag, execute the sketch-wrap-up workflow end-to-end. - Otherwise: execute the sketch workflow end-to-end.
