Write Idea

Turn a raw idea into docs/specs/<slug>/_idea.md — the Stage 0 artifact that answers "should we build this, and in what shape?" before write-prd answers "what exactly are we building?". The idea stage exists because unexamined business assumptions are the cheapest thing to fix here and the most expensive thing to fix after tasks are cut.

When this stage earns its cost

Use it for product-level ideas: greenfield features, ideas with real market/competitive questions, or anything where the right shape of the solution is still open. For a well-understood feature in a known area, say so and go straight to grilling/grill-with-docs → write-prd — a full idea study of an obvious feature is ceremony, not insight.
