# Simplify QE Agent Frontmatter to Only name and description (FIXED VERSION)
#
# Based on Claude Code best practices:
# https://docs.claude.com/en/docs/agents-and-tools/agent-skills/best-practices
#
# YAML frontmatter should contain ONLY:
# - name: agent identifier (required, max 64 chars)
# - description: what it does + when to use it (required, max 1024 chars)
#
# All other metadata goes in the body content for progressive disclosure
