▌
Dev Perf · eriklieben bundle
ALWAYS use this skill when investigating API performance, endpoint latency, or trace analysis. This skill provides the exact Aspire CLI commands and span pattern knowledge needed to diagnose N+1 queries, excessive storage reads, duplicate aggregate rehydration, and missing projections. You MUST consult this skill whenever the user mentions: slow endpoints, high latency, too many spans, N+1 patterns, storage reads, trace analysis, span counts, projection vs factory performance, before/after performance comparison, profiling requests, or asks 'why is this slow'. Even if you think you can handle it directly, this skill contains project-specific trace patterns and CLI commands you don't know without it.

Dev Watch · eriklieben bundle
Unified start/watch/test workflow for Aspire apps. ALWAYS use this skill when the user says: 'start it for testing', 'start and watch', 'run the app', 'start the apphost', 'watch the app', 'monitor for errors', 'keep an eye on logs', 'start the app and watch it', 'rebuild and check', 'anything weird in the logs?', 'babysit the app', or wants ongoing telemetry monitoring while they work. This skill starts the AppHost, discovers all resources, waits for health, then continuously monitors for errors and regressions.
