Why This Matters

✅ Build plugins in ANY project:

• Recruitment app → /recruitment-app/ ✓
• Marketing site → /marketing-site/ ✓
• Internal tools → /internal-tools/ ✓
• ANY directory → Works!

✅ Slash commands reference docs portably:

@~/.claude/docs/frameworks/claude/component-decision-framework.md
@~/.claude/plugins/marketplaces/domain-plugin-builder/plugins/domain-plugin-builder/skills/build-assistant/templates/...

✅ Scripts work from anywhere:

# Run from ANY directory:
bash ~/.claude/plugins/marketplaces/domain-plugin-builder/plugins/domain-plugin-builder/skills/build-assistant/scripts/validate-plugin.sh

✅ Portable across users and machines:

• Uses ~/ not /home/username/
• Uses $HOME in scripts
• No hardcoded paths
