Claude Skills by charlieviettq

Systematically triage failing tests by grouping errors, fixing root causes in priority order, and verifying incrementally. Use when CI fails, test suite is broken, or multiple tests fail after a refactor or merge.

Apply test-first discipline for behavior changes and bugfixes: define expected behavior, add or run a failing test, then implement minimally. Use when fixing bugs, changing logic, or adding features that need regression protection.

This skill should be used when working with pre-trained transformer models for natural language processing, computer vision, audio, or multimodal tasks. Use for text generation, classification, question answering, translation, summarization, image classification, object detection, speech recognition, and fine-tuning models on custom datasets.

UMAP dimensionality reduction. Fast nonlinear manifold learning for 2D/3D visualization, clustering preprocessing (HDBSCAN), supervised/parametric UMAP, for high-dimensional data.
