Claude Code Agent Architecture

Skill by ara.so — AI Agent Skills collection.

Overview

sanbuphy/learn-coding-agent is a research repository that reverse-engineers and documents the architecture of Claude Code (the CLI coding agent). It provides deep technical analysis of:

• Core agent loop: How messages, tools, and API calls form the execution cycle
• Tool system: 40+ built-in tools with permission flows
• Telemetry & privacy: What data is collected and how
• Hidden features: Undercover mode, killswitches, remote control
• Architecture patterns: Production-grade harness mechanisms

This is a learning resource for understanding production coding agents, not the actual Claude Code source code.
