Plan a feature before writing any code
This prompt makes the AI act as a tech lead and plan before anyone writes code. You get the approach, the files and data that change, the risks and a step-by-step build order, plus one simpler alternative.
Act as a tech lead. Before we write code, help me plan. Feature: [WHAT AND WHY] Current system: [SHORT DESCRIPTION OR RELEVANT CODE] Constraints: [e.g. must ship in 1 week, no new services, must work offline] Give me: a short summary of the approach, the files and parts that change, the data model changes, risks and unknowns, and a step-by-step build order where each step can be tested on its own. Offer one simpler alternative and say when it would be the better choice. Do not write code yet.
In Claude Code, use plan mode for this. Agree on the plan, then say "go ahead with step 1".
