How I Built a Full Production App in 2 Weeks with Claude Code (Zero Manual Coding)

Has your Claude Code session ever lost track of architectural decisions after context compaction? Have you tried running a multi-phase project with AI only to find it "forgetting" what it decided 30 minutes ago?

I built KnowMint — a full-stack marketplace with Solana payments, MCP server, CLI, x402 protocol support, and Cloudflare Workers deployment — in 14 days. 46 development phases. 16,000+ lines of code. Zero lines written by hand. Every phase passed Codex security review with ISSUES_FOUND: 0.

The key wasn't better prompts. It was a session management strategy that eliminates context compaction as a failure mode.

What you'll learn:

• The exact session structure that kept 46 phases coherent (one concern per session — never mix design and implementation)
• The Claude Code Harness + Codex MCP review loop that caught every security issue before it shipped
• How to give phase-level instructions instead of line-level instructions
• The 3 biggest mistakes I made (EVM dead code, premature infrastructure, mainnet anxiety) and how to avoid them
