One Human + One Agent = One Browser From Scratch

kept by eddie jan 28

A single Codex CLI agent built a basic HTML+CSS browser in three days with 20,000 lines of Rust, challenging the need for large multi-agent projects.

Why AI Swarms Cannot Build Architecture | An analysis of the structural limitations preventing AI agent swarms from producing coherent software architecture
AI agent swarms cannot produce coherent software architecture because architecture requires global invariants, temporal persistence, and enforcement authority—properties that swarms structurally lack.

Scaling long-running autonomous coding
Cursor's autonomous coding system using multi-agent orchestration successfully built a web browser from scratch and migrated codebases.

What you're actually writing when you write a SKILL.md
Skills are loader specifications with three execution stages, not static prompts, and understanding this runtime architecture is the key to writing efficient, portable agent skills.

How System Prompts Define Agent Behavior
System prompts shape coding agent behavior as much as the underlying model, with swaps between agents like Claude and Codex producing distinctly different workflows.
