AI Tool Tuesday: Gemini CLI vs Claude Code — When AI Coding Agents Battle It Out
Week 2 of my AI Tool Tuesday series, where I test AI tools in real scenarios so you don’t have to. What Are These Tools? Unlike last week’s Cursor review (which was an AI-enhanced editor), both Gemini CLI and Claude Code are coding agents — AI assistants that work directly from your command line to understand, modify, and debug your entire codebase without needing a specific IDE. Gemini CLI leverages Google’s Gemini model with a massive context window, letting it read extensive logs and trace runtime execution like a detective following breadcrumbs through your code. Claude Code (Anthropic’s command-line tool) excels at structured exploration and agentic searches, using tools like grep and find to navigate large projects methodically before making changes. Think of it as having two different senior developers: one who’s incredible at spotting bugs in real-time, and another who’s meticulous about understanding your entire project structure first.
