HOW TO BRIEF AN AI CODING AGENT BEFORE IT STARTS BUILDING
A practical brief for AI coding agents: the person, useful result, behaviour, boundaries, evidence and checks, with a worked example and reusable template.

A practical brief for AI coding agents: the person, useful result, behaviour, boundaries, evidence and checks, with a worked example and reusable template.
Design systems were built to give humans consistent options. Agents do not want options, they want a single correct answer. That turns the design system into constraint logic rather than a component library.
Most of the features I have shipped across solo projects were ones I wanted, not ones anyone asked for. Building for yourself is a brilliant starting point. It is a terrible finishing line.
AI features often fail because of where they sit in the experience—not because the technology is weak. Placement, timing, and flow matter more than raw capability.
Claude Design collapses thinking, design, and early building into one flow—not just faster UI. What that structural shift means for teams, and where people miss the point.
Junior routes are thinner, expectations stay high, and remote work made informal learning harder. Until we adapt how we develop people, the entry-level gap will stay—and building real things can be one path you control.
