Barrage skill

Barrage is a Go CLI that answers one question: when an app slows down, is it the app, or the database / cache underneath it? It fires HTTP, DB, and Redis load on one clock, buckets every layer's latencies onto the same timeline, and flags exactly which bucket a storage layer spiked in — and whether the app felt it.

Use this skill whenever:

• someone says "the API is slow", "p99 is high", "it works locally but not under load", "find the bottleneck"
• you need to check a project for perf problems (N+1, missing index, pool exhaustion, cache miss, rate limiter, slow journey step)
• you need a before/after proof for a migration, tuning pass, or release
• you are editing the barrage repo itself
