What problem does it solve? Local machines often lack a GPU, and locked-down Windows machines may lack WSL or administrator rights, blocking ML training, inference, and OCR workloads. This Skill routes those jobs to free Google Colab or Kaggle GPUs, handling CLI installation with uv, authentication, uploads, monitoring, artifact retrieval, and resource cleanup. ## Core Features & Use Cases - Environment-based routing: Chooses Colab CLI on Linux/macOS/WSL, native Kaggle on locked-down Windows, or a documented LiteBox/shim path for Colab without WSL. - Colab workflows: Supports one-shot colab run --gpu T4 job.py execution and named sessions for dependency installs, uploads, downloads, logs, and guaranteed cleanup via colab stop. - Kaggle workflows: Creates private GPU script Kernels with validated metadata, pushes them with an accelerator, polls status, and downloads outputs written under /kaggle/working. - Use Case: On a Windows laptop without admin rights, package a training script as a private Kaggle Kernel, run it on a Tesla T4, and retrieve the resulting model artifacts without installing anything system-wide. ## Quick Start Use the free-gpu skill to run my training script on a free Colab or Kaggle GPU and download the output artifacts.
