Determine Feature Slug

Interactively determine the next feature slug for personal workspace in the thoughts directory structure.

How It Works

1. Determine Namespace:

   • Default to git user: git config user.name | tr '[:upper:]' '[:lower:]' | tr ' ' '-'
   • Or accept namespace parameter
   • Personal workspace: thoughts/{namespace}/
   • Shared workspace: thoughts/shared/ (used by share-docs skill)

2. Find Next Number:

   • Scan thoughts/{namespace}/ directory for existing feature directories
   • Pattern: ^[0-9]{4}-.*
   • Find highest number and add 1
   • Default to 0001 if no features exist
