A viral YouTube clip ties Jev to Claude Code, but Jev cannot be the CLI chat model. This post covers the official skill, boundary hooks, MCP, and per-turn routing, contrasts NobodyWho’s 25-line minimal build, and discusses OpenAI fast-follow pressure.
From Anthropic's official guidance to Karpathy's program.md paradigm, from the two-strikes rule to Darwinian memory, from Spec-Driven to Eval-Driven — a long-form survey of how we write project files for AI coding agents, and the counterintuitive mental models worth borrowing.
What makes a production agent loop survive the real world? We extract the Agent Harness Pattern from Claude Code's source — a generalizable blueprint for building resilient, self-recovering AI agent runtimes.
Claude Code's source was briefly exposed. We read all 1,884 TypeScript files. Here is what the architecture reveals about where AI coding tools are actually heading.
A complete guide to the Claude Agent SDK, covering architecture, queries, custom MCP tool extensions, the Hook system for automation, debugging, and implementation.
