Documentation

README

Excerpt

If no argument is provided, check whether design/assets/entity-inventory.md exists:

If it exists: read it, find the first entity or screen with status "Needed" but no spec file yet, and use AskUserQuestion:
- Prompt: "The next unspecced item is [name]. Generate specs for it?"
- Options: [A] Yes — spec [name] / [B] Pick a different item / [C] Stop here
If no entity inventory: check design/assets/asset-manifest.md. If manifest exists, same flow above but reading from manifest.
If neither exists: start the Entity & Screen Inventory flow (Phase 0b below) rather than failing.

Phase 0b: Entity & Screen Inventory (runs when no arguments and no existing inventory)

This is the opening of the README. Read the full README on GitHub.
