# quality-standards: Inject quality block into CLAUDE.md
#
# Reads proactive skills from .skill-discovery-state.json, extracts their

# If no proactive skills are found or no checklists exist, falls back to
# the generic quality block template.
#
# Safe to run multiple times — removes existing block first.
