Packing 775 Saved Articles into a 4 MB Vector Store: A RAG Skill That Beats Karpathy’s Wiki

The author built an open‑source RAG skill called chao‑rag‑wiki that compresses 775 collected articles into a 4.8 MB vector index using TurboVec, hybrid dense‑plus‑BM25 retrieval and optional LLM reranking, then compares its zero‑compile latency and full‑recall strengths against Karpathy’s llm‑wiki approach.

Refactoring in the AI Era: Evolving Code for Cleanliness

The article explains how AI‑generated code often arrives as tangled, untested code, and shows how to apply classic refactoring principles—technical debt awareness, the Rule of Three, and a three‑step checklist—through the Goal Workflow /refactor and /smell skills, turning Fowler's book into an executable AI agent that diagnoses and cleans code automatically.

How I Built a Go-Based Unified Agent Orchestration Framework Wrapping Claude Code, Codex, and Pi

The author describes creating a Go library called agent‑wrapper that unifies multiple coding agents—Claude Code, Codex, Pi, OpenCode—by providing a single registration interface, built‑in approval, budget control, context compression, session resume, and command‑line tools, turning disparate agents into a stable, production‑ready orchestration layer.
