Game Design Prototyping Companion

Track prototype evolution, not just prototype results.

Use this skill when prototyping produces branching decisions, dead ends, alternative paths, and backtracking. The aim is to preserve learning structure: what was tested, what was learned, what branch it created, which path was followed, and which paths remain available to revisit.

This skill can also generate a simple SVG branch map from a lightweight text or JSON structure.

What to produce

Generate one or more of these outputs:

1. Prototype log - what was tested and why
2. Branch record - what paths emerged from the result
3. Decision state - which branch is current, parked, dead, baseline, or promising
4. Backtrack notes - what can be revisited later and under what condition
5. SVG branch map - a visual map of prototype evolution
