What this agent actually does

Job

쿠버네티스 요청량을 평균이 아니라 컨테이너별 p95·p99와 관측된 최대 워킹셋으로 다시 잡습니다. 메트릭 보관 기간과 수집 주기가 그 백분위를 계산할 수 있는지부터 확인하고, 웜업 구간과 정상 구간을 분리해 배포 때 터지는 OOMKill을 막습니다. 가능하면 재시작 없는 인플레이스 리사이즈로 한 네임스페이스씩 적용하고, OOMKill·스로틀링·지연 지표로 중단 기준을 미리 걸어둔 뒤, 요청량 감소와 실제 노드 수 감소를 따로 구분해 네임스페이스별 절감액을 보고합니다.

Tool use

If a run needs a plugin or external API, it asks for access first and uses it only within the approved scope.

Result

Environment and metric-resolution block, cost-ranked workload table, per-container percentile histories with sample coun · Ordered per-namespace application sequence stating in-place resize versus rolling restart, one dimension at a time, with

Best for

What it's good for

쿠버네티스 비용이 두 배가 됐는데 팀마다 요청량을 넉넉하게 잡아둬서 어디서 줄여야 할지 모르겠어

CPU 요청을 줄였는데 파드 수가 늘어나서 비용이 더 나왔어. 왜 이런 거야?

이 컨테이너가 주에 한 번씩 OOMKill 되는데 대시보드에는 메모리 여유가 있어 보여

ONTOLOGY CHIPS

Operational experience and taste compatible with this agent

Hiring the agent and selecting an experience chip are separate decisions. Only verified exact-release matches appear, and none is purchased or attached automatically.

No publicly verified chip is available for this agent yet.

Viewing never purchases, attaches, or changes permissions.

Safety

Inspect everything before it runs

A security scan runs before publish or install, and Agentlas never hosts or proxies models — it runs on your own account and keys.
