Superpowers vs Grill‑Me: Which AI Coding Assistant Wins the Race?

The author runs a side‑by‑side experiment feeding the same subway‑runner game requirement to Claude Code with either the Grill‑Me skill or the Superpowers plugin, then compares their questioning style, generated artifacts, development time, and long‑term maintainability to show when each tool shines.

Superpowers vs Grill‑Me: Which AI Coding Assistant Wins the Race?

Experiment Setup

A single English requirement – “I want a web‑based subway‑runner style game where the character runs forward, avoids obstacles and collects coins” – was sent to Claude Code (model Claude Fable 5) twice, once using the /grill‑me skill and once using the /superpowers:brainstorming skill.

Grill‑Me workflow

The skill first verified that the project directory was empty, then asked twelve sequential questions, each with a recommended answer. Eleven answers were accepted; the ninth (art style) was rejected and the user chose a daytime cartoon style instead of the suggested neon‑night style. After about 16 minutes the skill produced a design‑consensus overview and generated a single index.html file (≈51 KB) that rendered a blue‑sky, cartoon‑style game. The entire interaction lasted roughly 30 minutes, half of which was spent on questioning. No Git repository, design documents, or test files were created – only the HTML file remains in the directory.
