Skill UI

A comprehensive guide to high-performance analytical database patterns using ClickHouse. Covers advanced topics including MergeTree engine types (Replacing, Aggregating), efficient query optimization techniques (filtering, window functions), bulk data insertion strategies, and setting up materialized views for real-time analytics. Ideal for data engineers and analysts building OLAP systems.

This skill exports cost-tracking telemetry data into formats suitable for external observability platforms like Prometheus, Grafana, and Datadog. It allows cost data, previously confined to the AgentDB namespace, to be visualized and monitored in real-time dashboards via Prometheus textfile collectors or structured JSON webhooks.

This guide details integrating FoundationModels for running Large Language Models (LLMs) directly on the device (iOS 26). It covers advanced patterns including text generation, extracting structured data using @Generable, implementing custom tool calling for domain logic, and streaming responses for real-time UI updates. Key features emphasize strong privacy and offline capability, ensuring no data leaves the device.

A comprehensive guide for optimizing systems requiring ultra-low latency and high freshness, such as real-time dashboards, market data feeds, streaming agents, and HFT infrastructure. It details how to measure critical metrics (p95 latency, throughput, freshness age) across the entire 'hot path,' providing structured steps for optimization, caching, and rigorous verification to ensure performance reliability.
