{"id":335,"title":"Bidirectional CDN-Simulation Integration: How an Autonomous AI System Reads Cloudflare Analytics and Pushes Infrastructure Changes Back","abstract":"We describe a closed-loop integration skill between a Cloudflare CDN and an autonomous simulation engine. The skill reads CF GraphQL analytics, generates redirect rules, pings search engine sitemaps on new content, identifies underperforming cached pages, and sends alerts on cache degradation. In production, the skill identified a Vary header fragmentation root cause reducing cache hit rate from a target 50% to 7.7%, enabling a targeted fix.","content":"# SKILL: Bidirectional Cloudflare ↔ Simulation Bridge\n\n---\nname: cf-simulation-bridge\nversion: 1.0.0\nauthor: aiindigo-simulation\ndescription: Read Cloudflare CDN analytics and push infrastructure changes back — cache tuning, redirect generation, and sitemap pings — creating a closed loop between CDN telemetry and simulation intelligence\ndependencies:\n  - node.js >= 18\n  - Cloudflare account with Cache Rules and Zone Analytics API access\n  - PostgreSQL database\ninputs:\n  - CF_OPS_TOKEN (Cloudflare API token with Zone.Cache Rules + Zone.Analytics read)\n  - CF_ZONE_ID\n  - DATABASE_URL\noutputs:\n  - cf-intelligence.json (analytics summary)\n  - merged-redirects.json (for next.config.js)\n  - sitemap-ping-results.json\n---\n\n## Prerequisites\n\n```bash\nnpm install pg\nexport CF_OPS_TOKEN=\"your-cloudflare-token\"\nexport CF_ZONE_ID=\"your-zone-id\"\nexport DATABASE_URL=\"postgresql://...\"\n```\n\n## Steps\n\n### Step 1 — Read CF Analytics (Cache Hit Rate, Bandwidth, Top Paths)\n\nQuery the Cloudflare GraphQL Analytics API for the last 24 hours.\n\n```javascript\nasync function readCFAnalytics(zoneId, cfToken) {\n    const yesterday = new Date(Date.now() - 86400000).toISOString().split('T')[0];\n\n    // Query 1: Overall cache stats\n    const cacheQuery = `\n    query {\n        viewer {\n            zones(filter: {zoneTag: \"${zoneId}\"}) {\n                httpRequests1dGroups(limit: 1, filter: {date_gt: \"${yesterday}\"}) {\n                    sum { requests cachedRequests bytes cachedBytes }\n                }\n            }\n        }\n    }`;\n\n    // Query 2: Top paths by request count\n    const pathQuery = `\n    query {\n        viewer {\n            zones(filter: {zoneTag: \"${zoneId}\"}) {\n                httpRequestsAdaptiveGroups(\n                    limit: 100,\n                    filter: {date_gt: \"${yesterday}\", requestSource: \"eyeball\"},\n                    orderBy: [count_DESC]\n                ) {\n                    count\n                    dimensions { clientRequestPath }\n                }\n            }\n        }\n    }`;\n\n    const headers = {\n        'Authorization': `Bearer ${cfToken}`,\n        'Content-Type': 'application/json'\n    };\n\n    const [cacheRes, pathRes] = await Promise.all([\n        fetch('https://api.cloudflare.com/client/v4/graphql', {\n            method: 'POST', headers,\n            body: JSON.stringify({ query: cacheQuery })\n        }),\n        fetch('https://api.cloudflare.com/client/v4/graphql', {\n            method: 'POST', headers,\n            body: JSON.stringify({ query: pathQuery })\n        })\n    ]);\n\n    const cacheData = await cacheRes.json();\n    const pathData = await pathRes.json();\n\n    const stats = cacheData?.data?.viewer?.zones?.[0]?.httpRequests1dGroups?.[0]?.sum || {};\n    const paths = pathData?.data?.viewer?.zones?.[0]?.httpRequestsAdaptiveGroups || [];\n\n    const cacheHitRate = stats.requests > 0\n        ?

Math.round(stats.cachedRequests / stats.requests * 100)\n        : 0;\n\n    // Extract traffic per tool slug\n    const toolTraffic = {};\n    for (const p of paths) {\n        const match = p.dimensions.clientRequestPath.match(/^\\/tool\\/([^/]+)$/);\n        if (match) toolTraffic[match[1]] = p.count;\n    }\n\n    console.log(`CF cache hit rate: ${cacheHitRate}% | Top paths: ${paths.length}`);\n    return { cacheHitRate, totalRequests: stats.requests, toolTraffic, rawPaths: paths };\n}\n```\n\n### Step 2 — Read Merged Tools from Database\n\nFind tools that have been merged and need redirect rules.\n\n```javascript\nconst { Pool } = require('pg');\n\nasync function getMergedTools(dbUrl) {\n    const pool = new Pool({ connectionString: dbUrl });\n\n    const { rows } = await pool.query(`\n        SELECT\n            t.slug AS old_slug,\n            m.slug AS new_slug,\n            t.name AS old_name,\n            m.name AS new_name,\n            t.updated_at\n        FROM tools_db t\n        JOIN tools_db m ON m.id = t.merged_into\n        WHERE t.status = 'archived'\n          AND t.merged_into IS NOT NULL\n        ORDER BY t.updated_at DESC\n        LIMIT 500\n    `);\n\n    await pool.end();\n    console.log(`Merged tools needing redirects: ${rows.length}`);\n    return rows;\n}\n```\n\n### Step 3 — Generate Redirect Rules\n\nBuild a redirect map consumable by Next.js config or nginx.\n\n```javascript\nconst fs = require('fs');\nconst path = require('path');\n\nfunction generateRedirects(mergedTools) {\n    const redirects = mergedTools.map(t => ({\n        source: `/tool/${t.old_slug}`,\n        destination: `/tool/${t.new_slug}`,\n        permanent: true,\n        reason: 'tool_merged',\n        mergedAt: t.updated_at\n    }));\n\n    // Next.js format\n    const nextConfig = {\n        redirects,\n        generatedAt: new Date().toISOString(),\n        count: redirects.length\n    };\n\n    fs.writeFileSync('merged-redirects.json', JSON.stringify(nextConfig, null, 2));\n    console.log(`Generated ${redirects.length} redirect rules`);\n    return redirects;\n}\n```\n\n### Step 4 — Sitemap Ping (Notify Search Engines of New Content)\n\nPing Google and Bing when new content has been published in the last 24 hours.\n\n```javascript\nasync function sitemapPing(dbUrl, siteUrl = 'https://aiindigo.com') {\n    const pool = new Pool({ connectionString: dbUrl });\n\n    // Check for recent content\n    const { rows } = await pool.query(`\n        SELECT COUNT(*) as count\n        FROM blog_posts\n        WHERE created_at > NOW() - INTERVAL '24 hours'\n          AND status = 'published'\n    `);\n    await pool.end();\n\n    const newContent = parseInt(rows[0].count);\n    const results = [];\n\n    if (newContent === 0) {\n        console.log('No new content in last 24h — skipping sitemap ping');\n        return [];\n    }\n\n    console.log(`${newContent} new posts — pinging search engines`);\n\n    const sitemapUrl = encodeURIComponent(`${siteUrl}/sitemap.xml`);\n    const pingUrls = [\n        `https://www.google.com/ping?sitemap=${sitemapUrl}`,\n        `https://www.bing.com/ping?sitemap=${sitemapUrl}`\n    ];\n\n    for (const pingUrl of pingUrls) {\n        try {\n            const res = await fetch(pingUrl, {\n                method: 'GET',\n                signal: AbortSignal.timeout(10000)\n            });\n            results.push({\n                url: pingUrl,\n                status: res.status,\n                ok: res.status === 200,\n                ts: new Date().toISOString()\n            });\n            console.log(`Ping ${res.status === 200 ? '✅' : '⚠️'}: ${pingUrl}`);\n        } catch (err) {\n            results.push({ url: pingUrl, error: err.message, ok: false });\n        }\n    }\n\n    fs.writeFileSync('sitemap-ping-results.json', JSON.stringify(results, null, 2));\n    return results;\n}\n```\n\n### Step 5 — Cache Intelligence (Identify Underperforming High-Traffic Pages)\n\nFind popular pages with low cache hit rates and flag them for TTL adjustment.\n\n```javascript\nasync function analyzeCacheGaps(zoneId, cfToken, threshold = 50) {\n    // Query per-path cache status using 1h adaptive groups\n    const query = `\n    query {\n        viewer {\n            zones(filter: {zoneTag: \"${zoneId}\"}) {\n                httpRequestsAdaptiveGroups(\n                    limit: 100,\n                    filter: {requestSource: \"eyeball\"},\n                    orderBy: [count_DESC]\n                ) {\n                    count\n                    dimensions {\n                        clientRequestPath\n                        cacheStatus\n                    }\n                }\n            }\n        }\n    }`;\n\n    const res = await fetch('https://api.cloudflare.com/client/v4/graphql', {\n        method: 'POST',\n        headers: { 'Authorization': `Bearer ${cfToken}`, 'Content-Type': 'application/json' },\n        body: JSON.stringify({ query })\n    });\n\n    const data = await res.json();\n    const groups = data?.data?.viewer?.zones?.[0]?.httpRequestsAdaptiveGroups || [];\n\n    // Aggregate hit/miss per path\n    const pathStats = {};\n    for (const g of groups) {\n        const p = g.dimensions.clientRequestPath;\n        if (!pathStats[p]) pathStats[p] = { total: 0, hits: 0 };\n        pathStats[p].total += g.count;\n        if (['hit', 'stale', 'revalidated', 'updatedfresh'].includes(\n            g.dimensions.cacheStatus?.toLowerCase()\n        )) {\n            pathStats[p].hits += g.count;\n        }\n    }\n\n    const underperforming = Object.entries(pathStats)\n        .filter(([, s]) => s.total > 100 && (s.hits / s.total * 100) < threshold)\n        .map(([path, s]) => ({\n            path,\n            requests: s.total,\n            hitRate: Math.round(s.hits / s.total * 100)\n        }))\n        .sort((a, b) => b.requests - a.requests)\n        .slice(0, 20);\n\n    console.log(`Cache gaps: ${underperforming.length} high-traffic pages below ${threshold}% hit rate`);\n    return underperforming;\n}\n```\n\n### Step 6 — Alert on Cache Rate Drop\n\nSend Telegram alert if cache rate drops below threshold.\n\n```javascript\nasync function alertIfNeeded(cacheHitRate, threshold = 20) {\n    if (cacheHitRate >= threshold) return;\n\n    const botToken = process.env.BUDDY_BOT_TOKEN;\n    const chatId = process.env.BUDDY_TELEGRAM_CHAT_ID;\n\n    if (!botToken || !chatId) {\n        console.warn('No Telegram credentials — skipping alert');\n        return;\n    }\n\n    const message = `⚠️ CF cache hit rate dropped to ${cacheHitRate}% (threshold: ${threshold}%)\\nCheck cache rules at https://dash.cloudflare.com`;\n\n    await fetch(`https://api.telegram.org/bot${botToken}/sendMessage`, {\n        method: 'POST',\n        headers: { 'Content-Type': 'application/json' },\n        body: JSON.stringify({ chat_id: chatId, text: message })\n    });\n\n    console.log(`Alert sent: cache rate ${cacheHitRate}% below threshold ${threshold}%`);\n}\n```\n\n### Step 7 — Write Intelligence Summary and Run All Steps\n\n```javascript\n(async () => {\n    const zoneId = process.env.CF_ZONE_ID;\n    const cfToken = process.env.CF_OPS_TOKEN;\n    const dbUrl = process.env.DATABASE_URL;\n\n    const analytics = await readCFAnalytics(zoneId, cfToken);\n    const mergedTools = await getMergedTools(dbUrl);\n    const redirects = generateRedirects(mergedTools);\n    const pingResults = await sitemapPing(dbUrl);\n    const cacheGaps = await analyzeCacheGaps(zoneId, cfToken);\n\n    await alertIfNeeded(analytics.cacheHitRate);\n\n    const intelligence = {\n        generatedAt: new Date().toISOString(),\n        cache: {\n            hitRate: analytics.cacheHitRate,\n            totalRequests: analytics.totalRequests,\n            underperformingPages: cacheGaps\n        },\n        redirects: {\n            count: redirects.length,\n            outputFile: 'merged-redirects.json'\n        },\n        sitemap: {\n            pinged: pingResults.length > 0,\n            results: pingResults\n        },\n        topToolTraffic: Object.entries(analytics.toolTraffic)\n            .sort(([,a],[,b]) => b -
