👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Pull request overview
packages/web의 주간 리포트 생성 로직(weekly-report.ts)에서 eligibleUsers 관련 데이터 가공을 단일 루프로 통합해, 불필요한 중간 배열 생성과 반복 순회를 줄여 대규모 워크스페이스에서의 리포트 생성 성능을 개선합니다.
Changes:
userStats에서 eligibility(세션 3회 이상) 필터링 + candidate 배열 생성 작업을 단일 루프로 통합eligibleUserCount를eligibleUsers.length대신 루프에서 집계된 값으로 대체

- This optimization still creates an extra
baseobject plus three object spreads per eligible user. If the goal is to minimize allocations, pushing the candidate objects directly avoids the extra object and spread overhead while keeping the single-pass loop.

- The new loop creates an extra
baseobject per eligible user and then spreads it into three more objects. This adds an additional allocation and spread cost compared to constructing the candidate objects directly, partially undermining the stated goal of reducing allocations.
const base = { userId: u.userId, userName: u.name, avatarUrl: u.avatarUrl }
skillUsageCandidates.push({ ...base, value: u.skillCalls })
delegationCandidates.push({ ...base, value: u.agentCalls })
sessionCountCandidates.push({ ...base, value: u.sessionCount })
packages/web/src/lib/server/weekly-report.ts:356
- The candidate array element type is duplicated three times inline here and also matches
pickLeader’s parameter type. Introducing a local type alias will reduce repetition and make future changes less error-prone.

💡 What
weekly-report.ts의eligibleUsers데이터 가공 과정에서 발생하는 다수의.filter()및.map()호출을 단일 루프로 통합했습니다.🎯 Why
기존 방식은 O(N) 순회를 5번 이상 반복하고 중간 배열들을 불필요하게 생성하므로 GC 부하와 성능 저하를 야기했습니다.
📊 Impact
userStats배열 데이터 처리에 필요한 순회 횟수가 O(5N)에서 O(N)으로 감소하며, 메모리 할당 빈도가 크게 줄어 대규모 워크스페이스 리포트 생성 시 응답 시간이 개선됩니다.🔬 Measurement
packages/web의 테스트 스위트 통과를 확인하였으며, 타입 호환성 및 기존 데이터 흐름에 이상이 없음을 확인했습니다.PR created automatically by Jules for task 596302616946246885 started by @seonghobae
