When mobile Chrome keeps redirecting back to the login page after sign-in, the culprit isn't always OAuth or broken frontend state. In this case, the root cause was that the HTTP entry point for app-dev.daodao.so wasn't issuing a 301 redirect to HTTPS, so /auth/me requests sent with an http origin didn't include the auth_token cookie.
Stop stuffing all your tool descriptions into context at session start. Let the model write code, have the runtime execute it, and let tool definitions enter context only at the import line — Anthropic's GDrive→Salesforce example dropped from ~150K tokens to 2K, and Cloudflare's 2,500-endpoint schema shrank from 1.17M to 1K.
Karpathy proposed the llm-wiki pattern in 2026, having LLMs proactively maintain a markdown wiki instead of running RAG from scratch every time. Over 100 open-source implementations now exist, ranging from local CLI tools to serverless Telegram bots.
Cloudflare ran a Multi-Agent Code Review system internally for 30 days — 131K reviews, median 3 minutes. This post breaks down their architecture and compares it with solutions from Anthropic, GitHub, CodeRabbit, Greptile, and others.
AEO/GEO tools aren't a single category — they span three distinct layers: the input layer (is your website ready for AI to read), the traffic layer (how much are AI bots actually crawling), and the output layer (how is your brand mentioned in AI answers). This post maps out all three layers, from open-source self-hosted options to commercial SaaS.
env.AI is not just run(). It also exposes toMarkdown (document-to-Markdown conversion), autorag (managed RAG), gateway (external provider proxy), and models (metadata lookup). Understanding these four method groups is what unlocks Cloudflare as a full AI platform inside Workers.
Standard Playwright gets blocked by Cloudflare. Both playwright-extra + stealth and nodriver can bypass it. The final step is wrapping the solution into an MCP server so AI agents can use it automatically.
A brief error during nginx restart caused Cloudflare to mark the origin as unhealthy and stop forwarding requests, returning 502 on its own. The key clues: localhost hits to the origin return 200, and nginx access logs are completely empty. Just wait for Cloudflare to automatically re-check the origin — it recovers on its own.
Cloudflare Custom Error Pages require a paid plan. On the Free Plan, use a Worker with inline HTML to intercept 5xx responses instead.
Even when a route has prerender = true, Cloudflare Workers' Rollup bundler still attempts to bundle native modules, causing the build to fail. The fix is to move any native module work into a postbuild script.
To consolidate scattered notes and showcase diverse interests, I built a personal blog using Astro + Cloudflare Workers D1, paired with a Claude post skill for zero-friction writing.
In wrangler.jsonc, use custom_domain: true in routes with only the hostname as the pattern — no /* wildcard
Astro + the full Cloudflare suite — static-first, edge-computed, zero maintenance cost
