About this skill
Fire the moment the user proposes a build. Instantly surface the 1-3 consequential choices hidden in their idea. Can also be invoked with /before-building.
What this skill tells your AI
The instructions your AI receives, as published by davidondrej/skills in skills/thinking-and-docs/before-building/SKILL.md and read by Ahel’s review.
Respond INSTANTLY, from the gut. Do NOT read files, search, or use any tool — your very next message is the answer, based only on what the user just said. List the 1-3 truly consequential choices hidden in their idea (fewer is better). For each: the options in a few words + your gut recommendation. Classics: one-off vs repeated later, few lines vs proper module, biggest thing it could break. Skip anything minor. Then stop and wait for their answers.
