Generate and run realistic seed data for the project's database. Use when the user says "seed the database", "add some fake data", "I need test data", or the app looks empty during a demo.

Operate Railway infrastructure: create projects, provision services and databases, manage object storage buckets, deploy code, configure environments and variables, manage domains, troubleshoot failures, check status and metrics, and query Railway docs. Use this skill whenever the user mentions Railway, deployments, services, environments, buckets, object storage, build failures, or infrastructure operations, even if they don't say "Railway" explicitly.

Audit the app for real-time performance bottlenecks and fix them — slow queries, missing indexes, N+1 problems, cache misses, and polling that should be websockets. Use when the user says "make it faster", "it's slow under load", "optimize the DB", or "add real-time updates".
