How to write tests that catch bugs and prove the work — edge cases, error branches, mocks of external dependencies, the arrange-act-assert shape, regression tests for caught bugs, coverage as a map of the holes. For writing tests, raising coverage and TDD.

Read a web source — an article OR a non-article (GitHub repo, project homepage, service site) — and write a TIL document (in Korean). The H1 title is written in Korean. Published pieces (articles, posts, papers, tweets, videos) get a `원문: [원문 제목](URL)` titled-link source line and a `## 요약` section; non-articles get bare `<URL>` line(s) with NO `원문:` label, no titled link, and a fitting first heading like `## 소개`. Body structure follows the source's own job — analytical for a piece that argues, practical for one that teaches. The document shape is a closed spec enforced by scripts/check_format.py, which must print OK before the file is reported as written. Takes a URL as an argument. Use when the user asks to analyze an article/repo/site, document it, or organize a technical post.

Player-facing input signs for browser games: WASD, vehicles, flight, FPS mouse-look, and the #1 failure mode (inverted A/D). Mandatory control self-tests and a tiny test interface so you can verify A turns left before shipping. Load for ANY game with movement, steering, flying, driving, tanks, boats, mechs, drones, planes, karts, third-person follow cams — not only racing. Triggers on "controls", "WASD", "inverted", "steer", "flight", "airplane", "kart", "vehicle", "yaw", "roll", "pitch", "mouse look", "A/D".
