Reverse-engineered from npm source maps, these 10 design decisions explain why Claude Code is fast, safe, and recoverable under production conditions.

When and how to use Claude Code's /compact — what it actually does, the signals that say it's time, and the prompt patterns that produce a clean handoff.

Subagents are not just for parallelism — their real value is keeping irrelevant tool output out of the parent conversation.
