Define Project

Author and maintain the project-documentation layer that sits ABOVE the feature workflow — the product north star, and the architecture invariants that keep independently-built features from drifting apart.

This layer is OPTIONAL and pays off on large, multi-feature projects. A small repo does not need it — the feature workflow (frame-change → spec → build-in-waves) works fully without it, and nothing here is a gate. If the user is not sure they need it, say so and let them decide.

Modes

Pick the mode from what the user asked; ask if it is unclear.

• create — nothing exists yet. Author the layer from scratch.
• update — the layer exists. Revise it against a change signal.
• validate — the layer exists. Check it against a checklist and conformance.
