git
★ 34Git version control and GitHub CLI workflows for commits, branches, pull requests, and code reviews with professional commit message practices.
python
★ 34Use uv for fast Python project management, script execution, dependency handling, and tool installation. AVOID pip - always use uv commands (uv add, uv sync, uv run) instead.
transformers
★ 22Work with state-of-the-art machine learning models for NLP, computer vision, audio, and multimodal tasks using HuggingFace Transformers. This skill should be used when fine-tuning pre-trained models, performing inference with pipelines, generating text, training sequence models, or working with BERT, GPT, T5, ViT, and other transformer architectures. Covers model loading, tokenization, training with Trainer API, text generation strategies, and task-specific patterns for classification, NER, QA, summarization, translation, and image tasks.
