Monitors CockroachDB background job health by identifying failed, paused, and long-running jobs using SHOW JOBS and SHOW AUTOMATIC JOBS. Surfaces schema changes, backups/restores, automatic statistics collection, and SQL stats compaction jobs without DB Console access. Use when investigating schema change delays, failed backups, or automatic job issues.
Drizzle ORM v1 RC upgrade and migration patterns. Use when upgrading drizzle-orm/drizzle-kit to v1 (beta), migrating from Relational Queries v1 to v2, updating relations schema definitions, or working with new v1 features like `through` for many-to-many relations and object-based `where`/`orderBy` syntax.
PostHog feature flags for Ruby applications
PostHog integration for Flask applications
Run the SPARC Architecture and Implementation phases — design module boundaries, write pseudocode, implement code, and run tests
Use when the user asks to write SQL queries, optimize database performance, generate migrations, explore database schemas, or work with ORMs like Prisma, Drizzle, TypeORM, or SQLAlchemy.
Production-grade payment integration for Stripe, Paddle, Adyen, and more. Use when implementing checkout, subscriptions, webhooks, or billing.
Build, refactor, debug, or review a Convex backend inside a Next.js app. Use when the user mentions Convex, `convex/nextjs`, `npx convex dev`, `NEXT_PUBLIC_CONVEX_URL`, `useQuery`, `useMutation`, `usePaginatedQuery`, schema/indexes, auth, App Router server components/actions, realtime data, chat, notifications, collaborative features, or deploying Convex with Vercel. Also use when deciding whether Convex is a good fit for a Next.js app that needs reactive shared state. Do not use for generic frontend-only Next.js work or non-Convex backends unless the task is specifically about adopting, migrating to, or evaluating Convex.
Oracle APEX skills for Oracle APEX application development.
Workday SOAP integration. Manage Organizations. Use when the user wants to interact with Workday SOAP data.
Build and manage shipping integrations with Israeli carriers, including Israel Post, Cheetah, HFD, and Mahir Li, plus locker pickup services (BOX2GO, Shlager, Done). Use when user asks about "shipping Israel", "Cheetah delivery", "meshloach", "shipping label", "HFD", "locker pickup Israel", "tawit mishloach", or setting up carrier integrations for an e-commerce store. Covers carrier selection, Israeli address formatting, label generation, cross-carrier tracking system setup, and customer delivery notifications. Do NOT use for looking up a specific package tracking status (direct the user to mypost.israelpost.co.il or hfd.co.il instead). Do NOT use for international shipping outside Israel or customs/import.
Design and optimize systems for high concurrency, throughput, scalability, and elastic scale—concurrency models (threads, async/await, actors), lock-free patterns, connection pooling, caching stampede mitigation, horizontal scaling, load balancing, backpressure, queueing, rate limiting, bulkheads, read replicas, sharding, pool tuning, profiling, capacity planning, SLO-driven autoscaling, multi-region and CDN edge architecture. Use when the user asks about high concurrency, scalability, throughput, horizontal scaling, connection pooling, backpressure, rate limiting, caching stampede, read replica, sharding, autoscaling, capacity planning, lock contention, async scalability, or load balancing—not service decomposition (microservices-developer), event buses only (event-driven-architecture), generic CRUD (senior-software-engineer), SRE on-call only (site-reliability-engineer), load tests without architecture (performance-engineer), or cost-only FinOps (cloud-economist).
