r/ClaudeAI: Claude Code Source Deep Dive Part VII — Community Reverse-Engineers Multi-Agent Architecture, Context Compression, and Memory System Internals

A r/ClaudeAI contributor published Part VII of an ongoing series reverse-engineering Claude Code's source, focusing this installment on the multi-agent system and the context compression (compact) mechanism and memory architecture. The analysis covers how Claude Code coordinates subagents, compresses context to manage long sessions, and persists state — derived from direct source inspection rather than documentation. Prior installments in the series have drawn strong engagement from Claude Code power users and developers building agentic workflows on top of the platform.
