<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>

Questions about gsd-sketch.
- Which coding agents can use gsd-sketch?
- gsd-sketch installs in Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode and Windsurf with the skills CLI, using each agent's flag shown on this page. Flowy's auto-invocation, which fires a skill when your prompt matches, runs in Claude Code only.
