## Questions & Clarifications

### Common Questions

**Q: Why focus on four quality dimensions?**
A: These dimensions cover the most impactful quality aspects: code maintainability (complexity, duplication, style), test confidence (coverage + effectiveness), architectural health (organization, dependencies), and risk (security). Together they give a complete picture.

**Q: What makes this different from existing tools?**
A: Most tools focus on single dimensions. This tool integrates four dimensions with project-specific awareness, actionable remediation, and scoring. It's built for the snippet-pastebin project's structure (atomic design, Redux).

**Q: Can thresholds be customized?**
A: Yes, via .qualityrc.json. Teams can override defaults to match their standards.

**Q: How long will analysis take?**
A: Target <30 seconds for typical project. Actual time depends on codebase size and complexity.

**Q: Can it automatically fix issues?**
A: Not in v1.0. Tool identifies and recommends fixes; developers implement them. Auto-fix planned for v2.0.

**Q: Does it require external services?**
A: No. All analysis is local. Only npm audit API is called for dependency scanning.
