6-Layer agent system design canvas and 8+4 core patterns from the Claude Code source leak (512K lines TS). From the Circuit Breaker that stopped 250K/day wasted API calls with 3 lines, to 23-step bash AST security.
52 built-in tools' common interface, 10-step execution pipeline, safe=parallel/unsafe=sequential concurrency model, 5-stage permission pipeline, and 888KB Tree-sitter 23-step bash security.
