-**Artifact Workflow Enhancements:**
-- Schema-aware apply instructions with inline guidance and XML output
-- Agent schema selection for experimental artifact workflow
-- Per-change schema metadata via `.openspec.yaml` files
-- Agent Skills for experimental artifact workflow
-- Instruction loader for template loading and change context
-- Restructured schemas as directories with templates
-
-**Improvements:**
-- Enhanced list command with last modified timestamps and sorting
-- Change creation utilities for better workflow support
