AI-assisted development.
“The pope didn’t paint the Sistine Chapel.” The agent writes; the human directs — and every entry says which.
A practitioner's knowledge base for agentic coding patterns, DNS infrastructure, and the framework choices that fall out of building both. Every entry shipped so far is AI-drafted or AI-assisted under krow's editorial direction — labeled, not laundered. The about page explains the model.

The shortest path through the work that defines the site.
- guide Agentic Coding: Getting Started What agentic coding is, the plan–act–verify loop it runs on, and a first-task workflow that actually ships — a practical, experience-grounded guide.
- guide Writing an Effective CLAUDE.md Patterns for project instruction files that actually change how AI agents behave — boundaries, conventions, and the rules that matter.
- guide Reviewing AI-Generated Code A checklist and mental model for reviewing code you didn't write — what to look for when your coding agent hands back a diff.
- guide DNS Resolution: The Full Picture How DNS resolution works — root servers, TLD nameservers, record types, response codes, zone files, and why queries are nearly invisible.
- article How Websites Detect Bots in 2026 — JA4 & HTTP/2 Fingerprinting How modern bot detection works: TLS/JA4 and HTTP/2 fingerprinting, header order, and behavioral signals across Cloudflare, Akamai, and DataDome.
- article Building a Dev Blog with AI Agents in 7 Days 7 days building a real Astro 6 + Svelte 5 dev blog with Claude Code and Codex — concrete patterns, CLAUDE.md rules, drift, and what to skip.

Dead internet theory? Working as designed.
Everything here is AI-drafted and labeled — that's the premise, not an accident. Human-written entries will appear here as they ship.
