reactive-ui-patterns
About
This skill provides reactive UI patterns for smooth in-place updates when working with remote functions. It enables managing loading states and preventing page jumps through the `.current` property on stored queries. Use it to maintain scroll position and create seamless user experiences during data refreshes.

Reactive UI Patterns
Quick Start
<script lang="ts">
const data_query = get_data(); // Store in variable for .current access
async function save(id: string, value: string) {
await update_data({ id, value });
await data_query.refresh(); // Updates in place!
}
</script>
{#if data_query.error}
<p>Error loading data</p>
{:else if data_query.loading && data_query.current === undefined}
<p>Loading...</p>
{:else}
{@const items = data_query.current ?? []}
<div class:opacity-60={data_query.loading}>
{#each items as item}<!-- Content updates smoothly -->{/each}
</div>
{/if}
Core Principles
- Store queries:
const query = get_data()enables.currentproperty access - Use
.current: Prevents page jumps, keeps scroll position during updates - Initial load only: Show spinner when
.current === undefined, not on every refresh - Avoid
{#await}: Causes jarring page reloads - use stored query pattern instead

langchain
MetaLangChain is a framework for building LLM applications using agents, chains, and RAG pipelines. It supports multiple LLM providers, offers 500+ integrations, and includes features like tool calling and memory management. Use it for rapid prototyping and deploying production systems like chatbots, autonomous agents, and question-answering services.
Algorithmic Art Generation
MetaThis skill helps developers create algorithmic art using p5.js, focusing on generative art, computational aesthetics, and interactive visualizations. It automatically activates for topics like "generative art" or "p5.js visualization" and guides you through creating unique algorithms with features like seeded randomness, flow fields, and particle systems. Use it when you need to build reproducible, code-driven artistic patterns.
webapp-testing
TestingThis Claude Skill provides a Playwright-based toolkit for testing local web applications through Python scripts. It enables frontend verification, UI debugging, screenshot capture, and log viewing while managing server lifecycles. Use it for browser automation tasks but run scripts directly rather than reading their source code to avoid context pollution.
requesting-code-review
DesignThis skill dispatches a code-reviewer subagent to analyze code changes against requirements before proceeding. It should be used after completing tasks, implementing major features, or before merging to main. The review helps catch issues early by comparing the current implementation with the original plan.
