Context engineering, the practice of strategically structuring information to optimize AI interactions, has become a critical skill for developers looking to maximize productivity and code quality.</p> <h2 id="what-is-context-engineering">What is Context Engineering?</h2> <p>Context engineering is the deliberate design and organization of information that AI systems use to understand your project, requirements, and intentions. Unlike traditional documentation that&rsquo;s primarily for human consumption, context engineering creates structured knowledge that both humans and AI can leverage effectively.</p> https://justinlindh.com/posts/2025-07-29-claude-md-guidelines/ Tue, 29 Jul 2025 06:00:00 -0700 https://justinlindh.com/posts/2025-07-29-claude-md-guidelines/ <h1 id="example-claudemd-file-for-general-software-applications">Example CLAUDE.md file for general software applications</h1> <p>When working with Claude Code on software projects, a well-structured <code>CLAUDE.md</code> file can dramatically improve the quality and accuracy of AI assistance. This file serves as a project-specific instruction manual that helps Claude understand your codebase, conventions, and workflows.</p> <h2 id="what-claudemd-files-do">What CLAUDE.md Files Do</h2> <p>A <code>CLAUDE.md</code> file is a special documentation file that Claude Code automatically reads when working in your project directory.
