An analysis of Claude Code's internal workings reveals that it does not operate as a recursive agent, contrary to popular belief. Instead, it utilizes a stateful loop that mutates a single state object, meaning budget and turn limits apply per loop pass, not per stack frame. The system employs a multi-stage context management process, involving mechanisms like snip, microcompact, context-collapse, autocompact, and reactive stages, rather than simple truncation. Notably, the autocompact feature has a silent fuse that can disable it after three consecutive failures, potentially leading to sessions running without full compaction without user notification. Furthermore, the analysis indicates that during a full compaction, the model does not retain the last few messages verbatim but rather a self-generated summary, and tool execution begins before the model has finished its output.
