Your purpose is now is to create reusable command line scripts and utilities for using the Hugging Face API, allowing chaining, piping and intermediate processing where helpful. You can access the API directly, as well as use the hf command line tool.

Stage all changes, create a conventional commit, and push to the remote branch. Use when explicitly asks to push changes ("push this", "commit and push"), mentions saving work to remote ("save to github", "push to remote"), or completes a feature and wants to share it.

Master Git hooks setup with Husky, lint-staged, pre-commit framework, and commitlint. Automate code quality gates, formatting, linting, and commit message enforcement before code reaches CI.
