sayzardWe Built Secure, Scalable Agent Sandbox Infrastructure
이 글은 코드 실행이 가능한 AI 에이전트를 안전하고 확장 가능하게 운영하기 위한 샌드박스 인프라 구축 경험을 공유합니다. 두 가지 격리 패턴 중 에이전트 전체를 샌드박스 내에서 실행하고, 모든 자격 증명은 별도의 컨트롤 플레인에서 관리하는 방식을 채택했습니다. 프로덕션에서는 Unikraft 마이크로 VM을 사용해 빠른 부팅과 스케일링을 구현하며, 개발 환경에서는 동일 이미지를 Docker 컨테이너로 실행합니다. 이 구조는 에이전트가 비밀 정보에 접근하지 못하게 하면서도 독립적이고 유연한 확장성을 제공합니다.
Preventing AI agents from executing destructive terminal commands
Terminal Guardian MCP는 AI 에이전트가 터미널 명령어를 안전하게 실행하도록 다층 위험 분석과 샌드박스 실행 환경을 제공하는 Model Context Protocol 서버입니다. 명령어별 위험도를 평가해 즉시 실행, 확인 필요, 차단 등으로 분류하며, 실행 로그와 보안 이벤트를 구조화해 기록합니다. 또한 Git 커밋 메시지 자동 생성, 프로세스 관리, 네트워크 진단, 파일 시스템 접근, Docker 통합 등 개발자 워크플로우에 유용한 다양한 기능을 포함합니다. Claude AI 데스크톱과 통합 가능하며, AI 기반 터미널 명령어 실행의 안전성과 투명성을 크게 향상시킵니다.

각 pod마다 별도 git worktree를 부여해 런타임을 완전히 격리하는 샌드박스 운영 방식입니다. 공유 파일시스템 상태를 없애 동시성 간섭을 줄이고, 병합 부담을 실시간이 아니라 티켓 경계(in_progress→in_review)로 이동시킨다는 점이 실무적으로 유용합니다.
Stone Dong (@stone0dong) on X
@elalvarobalbin @swyx In our setup each pod gets its own git worktree at sandboxes/{podKey}/workspace — runtime is fully isolated, no shared filesystem state. Merge hell moves to the kanban in_progress → in_review boundary instead of happening in real time. You still pay it, just once per ticket
PrincipiaTwo days left for the latest Principia building contest! Be sure to get in your entries before the deadline, Monday at 12:00:00 GMT, the contest page should show the time left in your local timezone.
Apparatus
Hello and welcome to the sixth Principia building contest. This one is a bit special, as the contest is starting on the 15 year anniversary of the original release of [Apparatus](https://apparatus.voxelmanip.se), 11th May 2011. To commemorate this, we will be running a contest with the theme being... Apparatus! Namely, create a Principia level as if you were making an Apparatus level. This comes with a lot of limitations both in terms of the range of objects and what you can do with them, but will hopefully be an interesting challenge. You can either make a custom level (Apparatus) or alternatively a puzzle level (Challenge). Custom levels have endless possibilities for what you may create, while puzzle levels will have the classic objective of getting a marble into the basket. What will you create, given these limitations? ## Rules The objects you are allowed to use for your level are: - [Plank](/wiki/Plank) - [Cylinder](/wiki/Cylinder) - [Platform](/wiki/Platform) (Not allowed to attach anything to them!) - [Rubberband](/wiki/Rubberband) - [Wheel](/wiki/Wheel) - [Damper](/wiki/Damper) - [Weight](/wiki/Weight) - [Land mine](/wiki/Land_mine) - [Power Supply](/wiki/Power_Supply) - [Simple Motor](/wiki/Simple_Motor) (You can attach this to a platform to simulate a static motor) - [Power Cable](/wiki/Power_Cable) - [Signal Cable](/wiki/Signal_Cable) - [RC Basic](/wiki/RC_Basic) (Only simple buttons and horizontal sliders) - [Interactive Cylinder](/wiki/Interactive_Cylinder) (Enable the "Do not require dragfield" level property to make them work without a Dragfield) - [Ball](/wiki/Ball) or [Metal ball](/wiki/Metal_ball) (Your choice!) If you are an Apparatus pro, you may be aware that some of these objects behave differently in Principia, are shaped differently, or have more configuration options than in Apparatus. This is fine! The purpose of the contest is to promote creativity through the limited palette of objects and hopefully encourage those who don't know the ins and outs of every object in Principia to participate. Apparatus players used to do amazing things with just this set of objects! You are allowed to use things like Cam targeters and Cam zoomers if it makes the level better, but this should be well hidden to not break the illusion! You are also allowed to use [Y-splitters](/wiki/Y-splitter) or [OR gates](/wiki/OR_gate) to simulate the cable hub in Apparatus. If you are making a puzzle level then you are allowed to use plastic beams, an Object finder and a Game Manager in order to simulate the blue basket from Apparatus. In addition to that, the typical contest rules apply: - Only one level per player participating in the contest! - Old levels created before the contest are not eligible for entry. - Theft of entire levels is not allowed. Inspiration is allowed, plagiarism is not. ## Scoring Once the contest is over, a winner and a runner-up will be decided by the contest judge (ROllerozxa). Both will get their levels featured on the front page as well as awarded a stylish trophy badge on their user page. Depending on the amount of entries, there may be some other level entries that will be highlighted, for things that are interesting but didn't make it to the top. ## Submitting an entry Upload your level to the community site from in-game. You will then be prompted to go to the level page where you can add it to a contest in the dropdown.
HabrБезопасная песочница
Каждую неделю появляется новая песочница для агентов. Большинство таких решений опирается на встроенные механизмы Linux: namespaces, seccomp, cgroups и Landlock. Эти инструменты полезны, но они делят одно ядро с хостом и оставляют оператора внутри модели политик хоста. Полная microVM дает более четкую границу: ядро, которое вы сами выбрали, корневой диск, который можно проверить, сетевой линк, который можно записать, и отказ, который не становится состоянием хоста.
