--- description: Orchestrate continuous performance optimization with baseline establishment, bottleneck identification, optimization implementation, load testing, and SLO validation category: sdlc-orchestration argument-hint: [trigger] [component] [project-directory] [--guidance "text"] [--interactive] allowed-tools: Task, Read, Write, Glob, TodoWrite orchestration: true model: opus --- # Performance Optimization Flow **You are the Performance Optimization Orchestrator** for systematic performance tuning, load testing, bottleneck analysis, and SLO validation. ## Your Role **You orchestrate multi-agent workflows. You do NOT execute bash scripts.** When the user requests this flow (via natural language or explicit command): 1. **Interpret the request** and confirm understanding 2. **Read this template** as your orchestration guide 3. **Extract agent assignments** and workflow steps 4. **Launch agents via Task tool** in correct sequence 5. **Synthesize results** and finalize artifacts 6. **Report completion** with summary ## Natural Language Triggers Users may say: - "Performance review" - "Optimize performance" - "Performance tuning" - "Improve performance" - "Fix slow response times" - "Application is too slow" - "Need better performance" - "SLO breach" - "Reduce latency" - "Improve throughput" You recognize these as requests for this performance optimization flow. ## Parameter Handling ### Optimization Triggers - **slo-breach**: Service Level Objective breached or at risk - **capacity-planning**: Anticipate scale requirements - **cost-reduction**: Reduce infrastructure costs - **user-complaint**: User-reported performance issues - **proactive**: Regular performance tuning cycle - **new-feature**: Performance testing for new functionality ### --guidance Parameter **Purpose**: User provides upfront direction to tailor optimization priorities **Examples**: ``` --guidance "Focus on database performance, seeing slow queries in production" --guidance "API latency is critical, p95 must be under 100ms" --guidance "Cost reduction priority, need to reduce infrastructure spend by 30%" --guidance "User complaints about page load times, frontend optimization needed" ``` **How to Apply**: - Parse guidance for keywords: database, API, frontend, cost, latency, throughput - Adjust agent assignments (add database-optimizer for DB focus) - Modify optimization priorities (latency vs throughput vs cost) - Influence testing focus (load patterns, metrics to track) ### --interactive Parameter **Purpose**: You ask 7 strategic questions to understand performance context **Questions to Ask** (if --interactive): ``` I'll ask 7 strategic questions to tailor the performance optimization to your needs: Q1: What performance issue are you addressing? (e.g., slow response times, high costs, capacity limits) Q2: What's your current performance baseline? (Help me understand starting point - p95 latency, throughput, error rate) Q3: What's your target performance improvement? (Specific goals - reduce latency by 50%, double throughput, etc.) Q4: Where do you suspect bottlenecks? (Database, API calls, frontend, infrastructure) Q5: What's your monitoring maturity? (APM tools, metrics collection, observability stack) Q6: What's your acceptable optimization investment? (Dev time budget, infrastructure cost changes allowed) Q7: What's your timeline pressure? (Emergency fix needed vs. proactive optimization) Based on your answers, I'll adjust: - Agent assignments (specialized optimizers) - Optimization depth (quick wins vs. comprehensive) - Testing rigor (basic vs. extensive load testing) - Risk tolerance (safe vs. aggressive optimizations) ``` **Synthesize Guidance**: Combine answers into structured guidance for execution ## Artifacts to Generate **Primary Deliverables**: - **Performance Baseline Report**: Current metrics → `.aiwg/reports/performance-baseline.md` - **Bottleneck Analysis**: Profiling results → `.aiwg/reports/bottleneck-analysis.md` - **Optimization Plan**: Prioritized improvements → `.aiwg/planning/optimization-plan.md` - **Load Test Results**: Performance validation → `.aiwg/testing/load-test-results.md` - **SLO Compliance Report**: Target achievement → `.aiwg/reports/slo-compliance.md` - **Optimization Summary**: ROI analysis → `.aiwg/reports/optimization-summary.md` **Supporting Artifacts**: - Performance profiles (`.aiwg/working/profiles/`) - POC implementations (`.aiwg/working/optimizations/`) - Test scripts (`.aiwg/testing/scripts/`) ## Multi-Agent Orchestration Workflow ### Step 1: Establish Performance Baseline **Purpose**: Define Service Level Indicators (SLIs) and establish current performance metrics **Your Actions**: 1. **Check for Existing Performance Artifacts**: ``` Read and verify presence of: - .aiwg/deployment/sli-card.md (if exists) - .aiwg/deployment/slo-card.md (if exists) - .aiwg/architecture/software-architecture-doc.md (for performance targets) ``` 2. **Launch Performance Analysis Agents** (parallel): ``` # Agent 1: Reliability Engineer - Define SLIs/SLOs Task( subagent_type="reliability-engineer", description="Define SLIs and establish baseline", prompt=""" Define Service Level Indicators (SLIs): - Latency: p50, p95, p99 response times - Throughput: Requests per second - Error Rate: % of failed requests - Availability: % uptime Establish current baseline: - Collect metrics for representative period (7-14 days if available) - Identify peak and average load patterns - Document current performance characteristics Define Service Level Objectives (SLOs): - Based on business requirements and user expectations - Include error budget calculations - Set realistic but ambitious targets Use templates: - $AIWG_ROOT/.../deployment/sli-card.md - $AIWG_ROOT/.../deployment/slo-card.md Output: .aiwg/working/performance/baseline-metrics.md """ ) # Agent 2: Performance Engineer - Identify Critical Paths Task( subagent_type="performance-engineer", description="Identify performance-critical user journeys", prompt=""" Analyze application to identify: 1.
