112 Days Late: I Built a Product Anthropic Had Already Shipped
A field report with the full data. I spent 22 days and 215 commits building a macOS app to manage Claude Code sessions — Anthropic had shipped most of it 112 days before my first line, and my one competitive check scoped itself around the mobile line and missed the desktop redesign entirely. Includes the 48-feature audit (18 replaced / 15 overlapping / 15 unique), the review economics (~190 agents for ~170 findings, 33% hit rate at one stage), six dated incidents including a symlink that destroyed an 823MB corpus, and a full data appendix with timestamps.
