The source was extracted from npm source maps — the .js.map files that shipped with Claude Code contained a sourcesContent field with the full original TypeScript. Nearly two thousand files comprising the complete architecture.
36 AI agents analyzed and wrote the entire book in four phases:
Exploration 6 parallel agents read every file in the source tree
Analysis 12 agents wrote 494KB of raw technical documentation
Writing 15 agents rewrote everything from scratch as narrative chapters
Review & Revision 3 reviewers produced 900 lines of feedback; 3 agents applied all fixes
The entire process — from source extraction to final revised book — took approximately 6 hours. A final audit pass ensured no verbatim source code remained — every code block was rewritten as pseudocode with different variable names.
