In Part 14 we handled context misfires — cases where AgentContext builds a confident but wrong model of what the user is doing. That kind of pattern is useful. It shouldn't require the agent to watch you fail and recover a dozen…
If you have written any Spring Boot code, you have seen this: a class asks for another class in its constructor, and somehow the right object is just there. Nobody called new. Nobody looked anything up. Let's see who does…
Imagine you are looking for a word in a paper dictionary. You would not start at page 1 and flip one page at a time. You open it near the middle, see whether your word comes before or after that page,…

This CVE shares an incident timeline with certificate-validation findings in other ecosystems, but it is not an alias for the Python, Go, Java or Red Hat identifiers. Each ecosystem has a different artifact, version boundary and activation path. Use the…
핵심 요약: AI 에이전트가 API 키를 직접 보지 않고도 사용하게 만들려면, 에이전트의 컨텍스트에는 키의 이름만 전달하고 실제 값은 모델 바깥에서 확인(resolve)하도록 구성해야 합니다. 대표적인 방법은 세 가지입니다. 에이전트가 참조만 하고 절대 출력하지 않는 환경 변수, 시크릿 관리자(Secret…
The ticket read: "location button sometimes just spins forever." Not a crash, not an error toast — just a spinner that never stopped. QA couldn't reproduce it. It worked every time on the office Wi-Fi, every time on a laptop, every…
Someone opens a café app and taps "Find cafés near me." Android asks for location access. They choose "Don't allow." Sometimes the answer is: nothing. A dead-end screen, a "location is required" message, maybe a button that fires the same…
