frontend-design

onesixeight/IronMarket

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.

Skills
tessl-labs/springboot-error-handling
v0.2.0

Error handling for Spring Boot APIs — @ControllerAdvice, structured error

Contains:

springboot-error-handling

Production error handling that belongs in every Spring Boot REST API from day one. Apply whenever building, extending, or scaffolding a Spring Boot backend -- even if the task only asks for endpoints or CRUD operations. These patterns prevent stack trace leaks, inconsistent error formats, silent swallowed exceptions, and unstructured validation failures.

Skills

Optimize your skills and tiles: review SKILL.md quality, generate eval scenarios, run evals, compare across models, diagnose gaps, and re-run until scores improve.

Contains:

compare-skill-model-performance

Run task evals across multiple Claude models, compare results side-by-side, and optimise. Use when you want to understand how a skill performs across different models, identify model-specific gaps versus universal tile issues, or validate a skill before publishing it to the registry.

optimize-skill-instructions

Review and improve your SKILL.md with actionable recommendations. Reads skill bundle (SKILL.md + related docs), validates syntax, explains rubric, shows before/after scores. Use when reviewing skill quality, improving a skill file, checking skill scoring, making your skill better, or learning the skill rubric. This is the standalone review skill — for the full optimization cycle (review + evals + improve), use the `optimize-skill-performance-and-instructions` skill instead.

optimize-skill-performance-and-instructions

Run the full optimization cycle for a tile — review best practices, generate eval scenarios, run evals, diagnose gaps, fix, and re-run until scores improve. Use when someone says "optimize my skill", "improve my tile", "run evals", "benchmark my tile", or wants to measure and improve how well a tile helps agents solve tasks.

Skills

Implement data quality validation with Great Expectations, dbt tests, and data contracts. Use when building data quality pipelines, implementing validation rules, or establishing data contracts.

Skills

linkerd-patterns

wshobson/agents

Implement Linkerd service mesh patterns for lightweight, security-focused service mesh deployments. Use when setting up Linkerd, configuring traffic policies, or implementing zero-trust networking with minimal overhead.

Skills

Skills

deepgram-multi-env-setup

jeremylongshore/claude-code-plugins-plus-skills

Configure Deepgram multi-environment setup for dev, staging, and production. Use when setting up environment-specific configurations, managing multiple Deepgram projects, or implementing environment isolation. Trigger: "deepgram environments", "deepgram staging", "deepgram dev prod", "multi-environment deepgram", "deepgram config management".

Skills

cloud-penetration-testing

sickn33/antigravity-awesome-skills

Conduct comprehensive security assessments of cloud infrastructure across Microsoft Azure, Amazon Web Services (AWS), and Google Cloud Platform (GCP).

Skills

pt-maintaining-access

Skills

code-summarizer

ArabelaTso/Skills-4-SE

Generate concise summaries of source code at multiple scales. Use when users ask to summarize, explain, or understand code - whether it's a single function, a class, a module, or an entire codebase. Handles function-level code by explaining intention and core logic, and large codebases by providing high-level overviews with drill-down capabilities for specific modules.

Skills

abstract-trace-summarizer

ArabelaTso/Skills-4-SE

Performs abstract interpretation to produce summarized execution traces and high-level program behavior representations. Highlights key control flow paths, variable relationships, loop invariants, function summaries, and potential runtime states using abstract domains (intervals, signs, nullness, etc.). Use when analyzing program behavior, understanding execution paths, computing loop invariants, tracking variable ranges, detecting potential runtime errors, or generating program summaries without concrete execution.

Skills

langfuse-common-errors

jeremylongshore/claude-code-plugins-plus-skills

Diagnose and fix common Langfuse errors and exceptions. Use when encountering Langfuse errors, debugging missing traces, or troubleshooting integration issues. Trigger with phrases like "langfuse error", "fix langfuse", "langfuse not working", "debug langfuse", "traces not appearing".

Skills

langchain-core-workflow-b

jeremylongshore/claude-code-plugins-plus-skills

Build LangChain agents with tool calling for autonomous task execution. Use when creating AI agents, implementing tool/function calling, binding tools to models, or building autonomous multi-step workflows.
