UX Specify

Enriches a feature specification with UX requirements that implementation must satisfy. Runs AFTER the core specify skill completes.

Mode: BUILD (light)

Review the spec and add these UX sections if missing. Don't rewrite the spec — append UX requirements.

Error States Inventory: For each user action in the spec, ask: "What happens when this fails?" Add to the spec:

• Network failure during this action → what does the user see?
• Invalid input → what message, where, how to fix?
• Permission denied → what explanation, what recovery path?
• Timeout → what feedback, what retry mechanism?
