About gsd-sketch

gsd-sketch is a design skill that creates throwaway HTML mockups to compare design directions before implementation. It supports idea-based sketches and analysis of existing sketches, with findings stored in `.planning/sketches/`.

Key features

  1. 01HTML mockups with 2–3 variants
  2. 02Idea and frontier modes
  3. 03Uses spike findings to ground designs
  4. 04Sketch state and handoff integration
  5. 05Creates `.planning/sketches/` when needed

Use cases

  1. 01Comparing design directions before implementation
  2. 02Exploring consistency across existing sketches
  3. 03Preparing design findings for later build work

Install

Copy the command and run it in a terminal.

$npx skills add https://github.com/open-gsd/gsd-core --skill gsd-sketch

After installing, type/gsd-sketchin Claude Code to confirm it loaded.

$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.

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 `` 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.
Parse the first token of the `` 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).
