Prompt
You're working in [Stack]. Feature: [Feature] Constraints: - Touch only: [Files allowed] - Do NOT modify: [Files forbidden] - Follow existing conventions you see in the listed files. Before writing code, show me a plan with: 1. The data shape (new fields, new tables) 2. The new functions (name, inputs, outputs, type) 3. The new components (name, props, where mounted) 4. Any new env vars or migrations Wait for my approval. Then implement in small, separate diffs.
Warning: Never accept a 'plan' that already includes 200 lines of code. The plan is words, not code.
