“Design”

Event-Driven / CQRS / Saga Designer

Designs reliable event flows (Kafka/RabbitMQ/EventBridge): contracts, ordering, duplicates, sagas, and read models — including when NOT to use events.

Rate Limiting, Quota & Throttling Designer

Designs limiters (per-user/IP/tenant/API key), algorithm choice, and 429 contracts — including distributed counters and fairness.

Search & Recommendation System Designer

Designs search (ES/OpenSearch/vector/hybrid) with relevance tuning pipelines — includes ranking eval and zero-result handling.

Log Pipeline / SIEM Design (ELK/Loki/Splunk)

Designs application logging pipelines: schemas, sampling, retention, access control, and PII redaction at scale.

FTUE / Onboarding Flow Designer

Designs the first-time-user-experience beat-by-beat: teach by doing, hook timing, and drop-off measurement. Critical for F2P retention.

确定性设计（deterministic-design）

deterministic-design Skill 的源码项目：通过确定性测量和视觉评审循环，对渲染后的 UI 布局与可用性进行审计（MIT）。

CKW设计（ckw-design）

ckw-design Skill 的源码项目：涵盖前端设计方向、设计系统指导、视觉理念、空间检查、可用性审查和生产级 UI 优化工作流（MIT）。

更好的设计（better-design）

- 使用 Better Design 设计系统构建和审查界面

REST API Designer + Implementer

Produces a consistent, versioned REST API: OpenAPI spec first, then implementation, auth, rate limits, idempotency, and docs. Great for new services.

Design the error boundary: domain exceptions mapped to transport codes,

Property-Based Test Designer

Finds invariants and writes property-based tests (Hypothesis/fast-check) that discover edge cases humans miss.

Email/Notification Service Designer

Transactional + marketing notification system across channels with deliverability, templates, preferences, and suppression.

Analytics Event Pipeline Designer

Product analytics ingestion: schema, SDK, batching, idempotency, warehouse load.

Feature Engineering Transformer Designer

Production-safe feature pipelines: fitting on train only, consistent train/serve, and leakage-free transforms.

Model Validation / Experiment Designer (CV Strategy)

Chooses correct validation (grouped/time-series/nested CV), prevents over-opt, and reports uncertainty — the difference between local scores and prod results.

Model Monitoring / Drift Detection Designer

Production ML monitoring: data/concept drift, staleness, fairness over time, and retraining triggers — with alert thresholds tied to impact.

Partnership / Affiliate Program Design

联盟/分销/合作伙伴体系：佣金、规则、招募物料、防作弊。

Market Research / Survey Designer

问卷设计：避免诱导题，含配额、跳转逻辑与分析计划。

Notion / Knowledge Base Structure Designer

个人/团队知识库信息架构：主页结构、数据库关系、模板与维护规则。

Course/Syllabus Designer (Teachers)

为教师设计课程：学习目标 → 评估 → 活动的对齐（逆向设计）。
