+description: Run comprehensive web performance analysis (Core Web Vitals, network, accessibility)
+agent: Build+
+mode: subagent
+---
+
+Analyze web performance for the specified URL using Chrome DevTools MCP.
+
+URL/Target: $ARGUMENTS
+
+## Workflow
+
+### Step 1: Parse Arguments
+
+```text
+Default: Full audit (performance + accessibility + network)
+Options:
+  --categories=performance,accessibility,network  Specific categories
+  --device=mobile|desktop         Device emulation (default: mobile)
+  --iterations=N                  Number of runs for averaging (default: 3)
+  --compare=baseline.json         Compare against baseline
+  --local                         Assume localhost URL
+```
+
+### Step 2: Check Prerequisites
+
+```bash
+# Verify Chrome DevTools MCP is available
+which npx && npx chrome-devtools-mcp@latest --version || echo "Install: npm i -g chrome-devtools-mcp"
+```
+
+### Step 3: Read Performance Subagent
+
+Read `~/.aidevops/agents/tools/performance/performance.md` for:
+- Core Web Vitals thresholds
+- Common issues and fixes
+- Actionable output format
+
+### Step 4: Run Analysis
+
+Using Chrome DevTools MCP:
+
+1. **Lighthouse Audit** - Performance, accessibility, best practices, SEO scores
+2. **Core Web Vitals** - FCP, LCP, CLS, FID, TTFB measurements
+3. **Network Analysis** - Third-party scripts, request chains, bundle sizes
+4. **Accessibility Check** - WCAG compliance issues
+
+### Step 5: Generate Report
+
+Output in actionable format:
+
+```markdown
+## Performance Report: [URL]
+
+### Core Web Vitals
+| Metric | Value | Status | Target |
+|--------|-------|--------|--------|
+| LCP | X.Xs | GOOD/NEEDS WORK/POOR | <2.5s |
+| FID | Xms | GOOD/NEEDS WORK/POOR | <100ms |
+| CLS | X.XX | GOOD/NEEDS WORK/POOR | <0.1 |
+| TTFB | Xms | GOOD/NEEDS WORK/POOR | <800ms |
+
+### Top Issues (Priority Order)
+1. **Issue** - Description
+   - File: `path/to/file:line`
+   - Fix: Specific recommendation
+
+### Network Dependencies
+- X third-party scripts
+- Longest chain: X requests
+- Total blocking time: Xms
+
+### Accessibility
+- Score: X/100
+- X issues found
+```
+
+### Step 6: Provide Fixes
+
+For each issue, provide:
+1. **What**: The specific problem
+2. **Where**: File path and line number (if in repo)
+3. **How**: Code snippet or configuration change
+4. **Impact**: Expected improvement
+
+## Examples
+
+```bash
+# Full audit of production site
+/performance https://example.com
+
+# Local dev server
+/performance http://localhost:3000 --local
+
+# Mobile-specific audit
+/performance https://example.com --device=mobile
+
+# Compare against baseline
+/performance https://example.com --compare=baseline.json
+
+# Specific categories only
+/performance https://example.com --categories=performance,accessibility
+```
