# Product

Create or refine a product contract with the user's authority.

1. Inspect existing product, README, goals, release, and evidence sources.
2. Ask only for decisions that cannot be grounded safely from those sources.
3. State mission, users, pains, value, differentiation, non-goals, proven facts,
   assumptions, evidence gaps, and success signals.
4. Label aspiration and measurement honestly.
5. Preserve an existing PRODUCT.md unless the user authorizes replacement.
6. Return the document to the caller; Plan may use it as intent context.

Product does not select work, invoke a loop, repair itself, validate itself, or
choose delivery.
