Is This Really Required? Meet gh stack

The GitHub CLI extension 'gh stack' is gaining traction as a powerful tool for managing stacked pull requests, enabling developers to break large, complex changes into smaller, manageable, and reviewable layers. By allowing developers to stack branches that target the layer below them, the tool simplifies the workflow of rebasing and syncing, ensuring that diffs remain concise. This approach is particularly beneficial for improving code review quality, whether the reviewer is a human lead or an AI assistant. The article highlights how 'gh stack' handles the complexities of branch dependencies and suggests integrating it with AI agents to automate the creation and submission of these stacks. Ultimately, the tool helps maintain clean, modular codebases by encouraging developers to organize their work into logical, incremental units, reducing the friction associated with large pull requests and improving overall development productivity.
