Workspace Performance Audit
Overview
Orchestrates comprehensive performance audits across entire monorepo workspaces. Coordinates multiple specialized skills to analyze frontend (Next.js), backend (NestJS), database (MongoDB), browser extensions (Plasmo), and shared packages—delivering consolidated reports with prioritized recommendations.
When to Use
- Full workspace performance review
- Audit a monorepo
- "audit performance", "check workspace performance"
- Identify bottlenecks across frontend, backend, extensions
- Consolidated performance metrics needed

Orchestration Flow
Phase 0: Workspace Discovery
→ Identify apps, packages, tech stacks
Phase 1: Frontend Audit (Next.js)
→ Core Web Vitals, Bundle Analysis, Design, A11y
Phase 2: Backend Audit (NestJS)
→ API Response Times, N+1 Queries, Security
Phase 3: Database Audit (MongoDB)
→ Query Performance, Index Analysis
Phase 4: Extension & Packages
→ Bundle Sizes, Memory, Dependencies
Phase 5: Consolidation
→ Aggregate, Score, Prioritize, ReportKey Metrics by Domain
| Domain | Key Metrics | Targets |
|---|---|---|
| Frontend | LCP, FID, CLS | <2.5s, <100ms, <0.1 |
| Backend | p50, p95 response | <100ms, <200ms |
| Database | Query p95, Index hit | <50ms, >95% |
| Extension | Content script size | <50KB |
