Optimize
Benchmark, analyze, and optimize a function's execution time. Produces a before/after performance table with real numbers. Never presents a change without proving it is faster.
Performance Deity
A Claude skill from v0idOS/performance-deity.
Concurrency
Detect and fix race conditions and deadlocks. Fires thousands of concurrent requests to prove thread-unsafety, then applies the minimal synchronization primitive needed.
Database Deity
A Claude skill from v0idOS/performance-deity.
Ui
Fix UI rendering performance issues. Audits React re-renders, migrates animations to GPU-composited CSS properties, and virtualizes long lists. Target is 60 FPS.
Memory
Detect and fix memory leaks. Instruments memory tracking across thousands of iterations, proves the leak with growth data, identifies the uncollected reference, and verifies the fix.
Stress Test Deity
A Claude skill from v0idOS/performance-deity.
Telemetry Deity
A Claude skill from v0idOS/performance-deity.
Build Deity
A Claude skill from v0idOS/performance-deity.
Stress Test
Stress test and harden code against extreme inputs, malformed data, and simulated infrastructure failures. Acts as a red team. Documents every crash, then hardens the boundary.
Database
Diagnose and fix slow database queries. Runs EXPLAIN ANALYZE, identifies missing indexes, eliminates N+1 ORM patterns, and provides exact CREATE INDEX statements.
Network
Reduce API payload sizes and network latency. Profiles byte sizes, enforces compression and HTTP caching, and migrates heavy endpoints to GraphQL or protobuf when warranted.
Memory Deity
A Claude skill from v0idOS/performance-deity.
Telemetry
Add production observability to a function. Wraps it in an OpenTelemetry or Sentry trace span, injects execution metadata, and proposes a concrete alert rule with threshold and severity.
Concurrency Deity
A Claude skill from v0idOS/performance-deity.
Network Deity
A Claude skill from v0idOS/performance-deity.
Ui Deity
A Claude skill from v0idOS/performance-deity.
Build
Reduce CI/CD build times. Analyzes Dockerfiles, Webpack/Vite configs, and GitHub Actions workflows to identify the slowest step and apply targeted caching and build optimizations.
