+# Prototype: Example Prototype
+
+## One-Line Pitch
+
+A placeholder example showing how prototype cards should be structured.
+
+## Stage
+
+Prototype Candidate
+
+## Target User or Audience
+
+Potential early users, collaborators, or customers.
+
+## Problem / Desire / Curiosity
+
+This placeholder should be replaced with a concrete problem, desire, curiosity, or opportunity.
+
+## Learning Question
+
+What would we need to learn to know whether this idea deserves another step?
+
+## Smallest Useful Test
+
+Create a one-page concept note and ask three relevant people for feedback.
+
+## Expected Signal
+
+At least one person asks for a concrete next step, gives specific use-case feedback, or identifies a realistic context where the idea would matter.
+
+## Signal Strength
+
+S0
+
+## Promotion Target
+
+None yet
+
+## Risks
+
+The idea may seem interesting without being useful.
+
+## Agentic Suitability
+
+Agents may help turn rough notes into a sharper prototype card.
+
+## Next Action
+
+Replace this example with a real candidate or delete it after the first real prototype cards exist.
+
+## Notes
+
+Example only.
