How Claude Code Works — AI Summary

Summary

Claude Code transforms your terminal into an autonomous coding agent by utilizing a continuous loop of execution, verification, and context management. Unlike static chat windows, it actively interacts with your codebase through tools to complete tasks autonomously while maintaining security via configurable permission modes.

Key Topics

• Agentic Loop: This loop is the heart of Claude Code's autonomy. By evaluating its own work after every tool execution, the model can self-correct, which is fundamentally different from a static chat interface that generates text and stops.
• Context Compaction: When an agent works on a large project, it quickly hits its token limit. Context compaction automatically identifies what can be discarded or summarized, allowing the agent to work on larger codebases without losing memory.
• Tool-Based Agency: Tools allow the model to interact with the real world (the local file system). Without these, the model is trapped in a text output box; with them, it can actively solve bugs and modify code.
