Every new session, your AI agent forgets everything. Claude Code's leaked source hid a three-layer memory architecture and a design principle — 'Memory is hint, not truth' — that changes how you think about building agents. Here's the full breakdown.

The Claude Code source leak had everyone excited about KAIROS and model codenames. But the same codebase had a 3,167-line function, zero tests, silent model downgrades, and regex emotion detection. These aren't just Anthropic's mistakes — they're AI-generated code's default failure modes.

Prompt caching should save you 90% on token costs — but one obscure bug can silently make you pay 10x more. From DANGEROUS_uncachedSystemPromptSection to the cch=00000 billing trap hidden in Claude Code's DRM, here's why prompt engineers now need to be accountants too.

You spent months building a powerful AI agent. It just sits there waiting for you to say something. That's not a technical problem — it's a design philosophy problem. From KAIROS's Heartbeat Pattern to OpenClaw's background sessions, this is about when to let your agent decide to act on its own.

Hidden inside Claude Code's leaked source was a ~90-line file called undercover.ts — designed to make AI commits look like human commits. This surfaces a question the industry hasn't agreed on: when AI writes your code, should anyone know?

Claude Code: 512K lines of TypeScript, 64K lines of production code, zero tests. But the more interesting question isn't why Anthropic skipped tests — it's why they didn't use their own AI coding tool to write them. Static analysis, MITM proxies, cross-model testing, and the philosophical trap of asking the same brain to write the exam and grade it.
