Analyzes and optimizes application performance across frontend, backend, and database layers. Use when diagnosing slowness, improving load times, optimizing queries, reducing bundle size, or when asked about performance issues.
Optimize API response times through caching, compression, and efficient payloads. Improve backend performance and reduce network traffic.
Find and debug Chalk query plan cache misses from engine logs. Use when a query is replanning on every request, an "ad-hoc query request missed the plan cache" warning shows up, latency spikes from repeated planning, or someone asks why two seemingly identical queries don't share a cached plan. Drives the `chalk logs` CLI search.
Read-only audit of performance and reliability — event-loop discipline, streaming and backpressure, memory and CPU diagnostics, shutdown/timeout/job habits, resilience topology (circuit breakers, retry budgets, queue bounds), and frontend delivery (Core Web Vitals, bundle size, hydration) — with evidence per finding and a SHIP / FIX / BLOCK verdict. Use when a service or page is slow, memory climbs, tail latency is bad, a worker OOMs, before a load event, or 'почему тормозит'. Measures and reports; rewrites no hot paths. Do not use for retry/idempotency contracts (awesome-error-standards) or render style rules (awesome-code-standards).
End-to-end front→back performance debugging for the Kodus web app. Use when a screen is slow, blank, looping, or you need to trace a UI perf problem down to the API query. Drives Playwright/Chrome MCP to open + measure the screen, then reads the API use-case/repository and the DB (Postgres/Mongo indexes, explain) to find and fix the root cause, verifying live.
