Loop Engineering: The End of Prompting
How the shift from writing prompts to designing systems is redefining how we work with AI coding agents

Designing, building, and running unattended AI coding loops: the building blocks, patterns, model tiering, and hard realities of loops that work while you sleep.
Hooks are the enforcement layer inside these loops. Start with the Cursor hooks.json guide for the guardrails, then come back for the loop architecture.

A deep dive into the six primitives that every unattended AI coding loop needs to function

How GitHub Issues, CI, Slack, and Linear become loop input: the intake pipeline nobody explains

A step-by-step walkthrough of scaffolding and running Daily Triage L1 on Souso (smart-cart): report-only, zero risk

Seven production loop patterns with concrete Souso (smart-cart) scenarios, cadences, and risk levels

Failure modes, token economics, and Souso-specific guardrails: what nobody tells you about unattended AI coding loops

Running every loop role on a frontier model is expensive and unnecessary. Here's what the research says about tiering models per role, and what's still missing.
