skill

anombyte93

AI-powered PRD generation for Claude Code with taskmaster integration

spring-boot-resilience4j

giuseppe-trisciuoglio

Implement fault tolerance and resilience patterns in Spring Boot applications using Resilience4j library. Use for circuit breaker, retry, rate limiter, bulkhead, time limiter, and fallback patterns. Apply when building resilient microservices that need to handle failures gracefully, prevent cascading failures, and manage external service dependencies.

protocolsio-integration

K-Dense-AI

Integration with protocols.io API for managing scientific protocols. This skill should be used when working with protocols.io to search, create, update, or publish protocols; manage protocol steps and materials; handle discussions and comments; organize workspaces; upload and manage files; or integrate protocols.io functionality into workflows. Applicable for protocol discovery, collaborative protocol development, experiment tracking, lab protocol management, and scientific documentation.

spring-boot-integration-test-patterns

giuseppe-trisciuoglio

Integration testing patterns with Testcontainers for Spring Boot applications. Database, cache, and external service testing. Use when writing integration tests that require real service dependencies.

modern-javascript-patterns

wshobson

Master ES6+ features including async/await, destructuring, spread operators, arrow functions, promises, modules, iterators, generators, and functional programming patterns for writing clean, efficient JavaScript code. Use when refactoring legacy code, implementing modern patterns, or optimizing JavaScript applications.

rag-implementation

wshobson

Build Retrieval-Augmented Generation (RAG) systems for LLM applications with vector databases and semantic search. Use when implementing knowledge-grounded AI, building document Q&A systems, or integrating LLMs with external knowledge bases.

algorithmic-art

anthropics

Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.

anndata

K-Dense-AI

Manipulate AnnData objects for single-cell genomics. Load/save .h5ad files, manage obs/var metadata, layers, embeddings (PCA/UMAP), concatenate datasets, for scRNA-seq workflows.

shap

K-Dense-AI

Model interpretability and explainability using SHAP (SHapley Additive exPlanations). Use this skill when explaining machine learning model predictions, computing feature importance, generating SHAP plots (waterfall, beeswarm, bar, scatter, force, heatmap), debugging models, analyzing model bias or fairness, comparing models, or implementing explainable AI. Works with tree-based models (XGBoost, LightGBM, Random Forest), deep learning (TensorFlow, PyTorch), linear models, and any black-box model.
