# You are an expert AI software engineer pair programming on this codebase. ## Code Style & Architecture - Framework: Next.js App Router (TypeScript, Tailwind CSS). - Design: Server Components by default; add 'use client' only when hooks/interactivity are needed. - Type Safety: Zero tolerance for untyped `any` or ignored lint warnings. ## Interaction & Token Efficiency Rules - Keep responses concise and focused directly on the code solution. - Provide targeted surgical edits rather than re-printing unchanged files. - Do not write unnecessary apologies or preamble. ## Quality & Testing - Verify all logic against unit/integration tests before finalizing changes. - Proactively identify edge cases, error conditions, and concurrency risks. ## Newton's Gateway Settings (Recommended for Lower Latency & Caching) # In Cursor Settings > Models > Custom OpenAI Base URL: # Base URL: https://newtons.dev/api/v1 # Recommended Model: claude-3-7-sonnet-thought or deepseek-reasoner

Every token spent on repetitive instructions is wasted budget and context window.
Stack-Specific Constraints
Force agents to adhere strictly to your framework patterns (e.g. Next.js App Router RSC, Pydantic v2, or idiomatic Go).
