OpenAI's Cookbook frames Codex Goals as a thread-scoped completion contract: the objective persists, but completion must be checked against evidence. This post fills in the official spec angle around SP-192, SP-197, and SP-207.

Jarrod Watts looked inside Codex Goals and found that it solves early stopping, not long-run drift. The real long-running agent stack needs upfront clarification, multi-agent review, and memory outside the context window.

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.

Paweł Huryn proposes the Vibe Engineering framework: instead of accepting raw AI output, use Context Engineering, Intent Engineering, and Sub-agent orchestration to upgrade AI coding from 'lucky demos' to 'reliable products'.
