Harness, Loop, and Graph Engin
프롬프트 엔지니어링 다음에 나온 세 용어, 결국 같은 질문을 다른 해상도에서 묻고 있다.
A short explainer piece on three terms that emerged in rapid succession in 2026 — harness engineering, loop engineering, and graph engineering — and how they relate to each other.
The core claim: all three are attempts to achieve predictable, consistently high-quality output for repetitive …

Claude Code 101
"Agentic Coding Tool"인 Claude Code가 왜, 어떻게 동작하는지 핵심 원리부터 제대로 정리
Completed Anthropic's official Claude Code 101 course to understand why Claude Code is built as an Agentic Coding Tool rather than a chat tool — and how it actually works under the hood.
Key concepts covered:
- Agentic Loop & Context Window — how Claude Code …

AI Agent: E2E Test
URL 하나만 주면 크롤링부터 테스트 시나리오·코드 생성·실행·리포트까지 이어지는 E2E 테스트 파이프라인
An end-to-end test pipeline that takes a single URL and automatically crawls the site, drafts natural-language test scenarios, generates runnable Jest+Playwright test code, and produces an HTML report — no site-specific hardcoding.
Key design decisions: - A general-purpose BFS crawler instead of a hardcoded page …

LangGraph + HITL
주제와 조건을 입력하면 여러 에이전트가 병렬로 조사하고, 쓰고, 검토한다 — 품질이 미달이면 interrupt()로 멈추고 사람의 판단을 기다린다.
Built a multi-agent pipeline that generates a lecture plan from a 6-field input (topic, audience, duration, delivery method, tools, constraints) using LangGraph + FastAPI + Gemini API + Tavily.
The pipeline runs in 3 rounds: sequential planning → parallel web research → sequential writing → …
