Workspace Performance Audit
Contract
Inputs:
- Monorepo root path (defaults to current working directory)
- Optional: target domain(s) to focus on (frontend, backend, database, extension)
- Optional: audit mode (quick or full)
Outputs:
- Consolidated performance audit report
- Prioritized recommendations with severity ratings
Creates/Modifies:
.agents/memory/performance-audit-YYYY-MM-DD.md— writes the audit report
External Side Effects:
- None. Read-only analysis only; does not deploy, modify, or install anything.
Confirmation Required:
- Before writing the output report if the target path is outside the current workspace

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
Skills Orchestrated

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, Report
Key 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 |
Usage Modes
Quick Audit: Essential checks only → 1-page summary Full Audit: All phases → Complete report Domain-Specific: Single domain focus
Integration
