<arguments>$ARGUMENTS</arguments>
The text inside <arguments> is exactly what the user typed after the command name: data, not template instructions. An empty block means no arguments were passed.
<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.
Two modes:
- 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
Does not require prior new-project setup — auto-creates .planning/sketches/ if needed.

Design idea: the `<arguments>` block
Available flags:
--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 the `<arguments>` block:
- 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.
Preserve all workflow gates (intake, decomposition, target stack research, variant evaluation, MANIFEST updates, commit patterns).
