Beyond Laravel: Applying the Agent Harness to Any Stack

The Strategy Is the Point This series followed a Laravel + React codebase. But if you've been reading for the strategy and not the syntax, you already know: none of this is Laravel-specific . Tests before agents. Linting as machine-checkable standards. Clean architecture so the agent follows patterns instead of inventing them. Trunk-based development for fast feedback. Harness files that scope guidance to where the agent is working. Custom skills that turn your workflow into structure. Every step has an equivalent in whatever stack you're using. The tools change. The progression doesn't. The Seven Steps Here's the agent harness approach distilled to its language-agnostic core. Each step builds on the ones before it. You cannot skip ahead: the entire system is load-bearing. Step 1: Test Infrastructure What you're doing: Wrapping the existing codebase in tests that run against real dependencies (the same database engine, the same cache, the same queue) so you have a machine-checkable saf
