| 5 | ## Playwright Browser Awareness |
| 6 | |
| 7 | **Note**: This agent primarily performs static SEO analysis and does not directly use Playwright MCP tools. However, when performance testing requires browser automation: |
| 8 | |
| 9 | 1. **Reference Constitution**: See `/templates/playwright/playwright-constitution.json` for browser management |
| 10 | 2. **Session Awareness**: Browser-testing agents handle Chromium installation separately |

| 30 | ## Constitution Integration |
| 31 | |
| 32 | Before performing SEO analysis, check for project constitutions in `.frontend-dev/`: |
| 33 | |
| 34 | ### Loading Constitutions |
| 35 | |
| 36 | ```javascript |
| 37 | // Check for project configuration |
| 38 | const configPath = '.frontend-dev/config.json'; |
| 39 | const config = await Read(configPath); |
| 40 | |
| 41 | // Load page-specific testing constitutions |
| 42 | const pageConstitutions = await Glob('.frontend-dev/testing/*.json'); |
| 43 | for (const path of pageConstitutions) { |
| 44 | const constitution = JSON.parse(await Read(path)); |
| 45 | // Extract page URLs, meta requirements, features |
| 46 | } |
| 47 | |
| 48 | // Load login constitution for understanding site structure |
| 49 | const loginConstitution = await Read('.frontend-dev/auth/login-constitution.json'); |
| 50 | ``` |
| 51 | |
| 52 | ### Constitution-Driven SEO Analysis |
| 53 | |
| 54 | When constitutions exist, use them to: |
| 55 | |
| 56 | 1. **Page Inventory from Constitutions** |
| 57 | - Get list of pages from `.frontend-dev/testing/*.json` |
| 58 | - Map page URLs for crawlability analysis |
| 59 | - Identify public vs authenticated pages |
| 60 | |
| 61 | 2. **Extract SEO Requirements** |
| 62 | - Check if constitutions define SEO requirements |
| 63 | - Look for `seo` or `meta` fields in page constitutions |
| 64 | - Verify requirements match implementation |
| 65 | |
| 66 | 3. **Performance Budget Validation** |
| 67 | - Use performance budgets from `config.json` |
| 68 | - Validate against constitution-defined thresholds |
| 69 | |
| 70 | ### Constitution Files Reference |
| 71 | |
| 72 | | Constitution File | SEO Use | |
| 73 | |-------------------|---------| |
| 74 | | `.frontend-dev/config.json` | Site settings, performance budgets, base URL | |
| 75 | | `.frontend-dev/auth/login-constitution.json` | Login page URL, auth pages to exclude from crawl | |
| 76 | | `.frontend-dev/testing/[page].json` | Page URLs, features for content analysis | |
| 77 | |
| 78 | ### SEO Constitution Fields |
| 79 | |
| 80 | If constitutions include SEO requirements, they may look like: |
| 81 | ```json |
| 82 | { |
| 83 | "pageName": "Dashboard", |
| 84 | "pageUrl": "/dashboard", |
| 85 | "seo": { |
| 86 | "title": "Dashboard - My App", |
| 87 | "description": "View your analytics and manage settings", |
| 88 | "indexable": false, |

| 93 | "targetCLS": 0.1 |
| 94 | } |
| 95 | } |
| 96 | ``` |
| 97 | |
| 98 | ### Reporting Constitution Status |

| 100 | Include in SEO report: |
| 101 | ```markdown |
| 102 | ## Constitution Status |
