Full Analysis

Before entrusting changes to Claude Code, it is advisable to prepare a CLAUDE.md file and ask the AI to explore the codebase before any modifications. Jumping straight to implementation is presented as a source of token waste and misleading evaluation of responses. These practices are also recommended for other sophisticated AI tools.

Claude first reads CLAUDE.md, then explores the codebase

A persistent framing can be recorded in a CLAUDE.md file, presented as the first file read by the assistant upon starting a project. It is also recommended to ask the AI to explore the codebase before any modifications. A prompt reused for each new project includes two simple instructions: start by examining the existing solution and the design system in use, and refrain from changing anything immediately.

Jumping straight to code wastes tokens and skews judgment

Jumping directly to implementation is described as the most common pitfall among product designers. This haste leads to unnecessary token waste and the mistaken belief that the assistant only produces mediocre solutions. The error pointed out lies in starting without prior understanding of the product by the AI.

Providing context: architecture, components, conventions, constraints

The first recommended step is to provide the assistant with adequate context. This includes understanding the existing architecture, components, conventions, and constraints of the product. This approach is proposed for Claude Code and, more broadly, for other AI tools considered sophisticated.
