error-handling-patterns
About
This skill provides Svelte 5 error handling patterns for developers. It covers error boundaries using `<svelte:boundary>`, async operations with loading states, and form error management. Use it to implement graceful error handling with retry functionality and pending states in your Svelte applications.

Error Handling Patterns
Quick Start
<svelte:boundary>
<ul>
{#each await get_contacts() as contact}
<li>{contact.name}</li>
{/each}
</ul>
{#snippet pending()}
<div class="loading">Loading...</div>
{/snippet}
{#snippet failed(error, reset)}
<div class="error">
<p>Error: {error.message}</p>
<button onclick={reset}>Retry</button>
</div>
{/snippet}
</svelte:boundary>
Core Principles
- Error boundaries: Use
<svelte:boundary>to catch component errors - Pending snippet: Show loading state while awaiting data
- Failed snippet: Display errors with retry via
resetfunction - Await expressions: Use
{#each await query()}directly in markup - Granular boundaries: Wrap individual features, not entire pages
- Form errors: Check remote function
.errorproperty (e.g.,create_contact.error)

sglang
MetaSGLang is a high-performance LLM serving framework that specializes in fast, structured generation for JSON, regex, and agentic workflows using its RadixAttention prefix caching. It delivers significantly faster inference, especially for tasks with repeated prefixes, making it ideal for complex, structured outputs and multi-turn conversations. Choose SGLang over alternatives like vLLM when you need constrained decoding or are building applications with extensive prefix sharing.
evaluating-llms-harness
TestingThis Claude Skill runs the lm-evaluation-harness to benchmark LLMs across 60+ standardized academic tasks like MMLU and GSM8K. It's designed for developers to compare model quality, track training progress, or report academic results. The tool supports various backends including HuggingFace and vLLM models.
llamaguard
OtherLlamaGuard is Meta's 7-8B parameter model for moderating LLM inputs and outputs across six safety categories like violence and hate speech. It offers 94-95% accuracy and can be deployed using vLLM, Hugging Face, or Amazon SageMaker. Use this skill to easily integrate content filtering and safety guardrails into your AI applications.
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.
