Topic Bible - Harness Engineering v1.0

This video will provide a overview look at the setup Covering: The Core Architecture: Explaining the "Model + Harness" philosophy and the "Thin Harness, Fat Skills" design pattern that keeps logic in Markdown and the conductor under 200 lines. Technical Engines: How the PPAF cycle (Perception, Planning, Action, Feedback) drives execution and how the four-tier memory architecture (Working, Episodic, Semantic, and Personal) ensures the agent learns over time. Strengths and Gains: The documented performance leaps, such as the 6x performance gap and 64% improvement on SWE-bench benchmarks compared to bare models. Weaknesses and Failures: A look at common anti-patterns like "one-shotting" (trying to do everything in one turn) and "god-tools" that lead to hallucinations and inefficiency. Gaps and Improvements: Exploring open problems like skill discovery beyond 50 files and the Manager-Worker pattern, which uses advanced models to supervise and teach cheaper ones. Comparative Analysis: How this "Bible" approach compares to other systems, highlighting the difference between lazy-loading schemas (like Claude Code) versus eager-loading (like Codex and OpenCode).
