<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. </objective>

<runtime_note> **Copilot (VS Code):** Use `vscode_askquestions` wherever this workflow calls `AskUserQuestion`. </runtime_note>

<context> 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). </process>
