What problem does it solve? Reviewing long pull requests or branch diffs to understand what actually changed is time-consuming, especially when commit messages are noisy or uninformative. This Skill condenses net changes into a short, readable summary focused on what and why. ## Core Features & Use Cases - Flexible Input Handling: Accepts a PR number, branch name, GitHub PR URL, a custom base comparison, or defaults to comparing the current branch against main. - Net-Change Focus: Summarizes core functionality, API/model changes, developer experience improvements, and bug fixes rather than listing individual commits. - Authenticated GitHub Access: Uses the gh CLI for all GitHub operations, ensuring private repositories work with existing authentication. - Use Case: Before approving a teammate's PR #45, run the Skill to get a one-line summary plus bullet points of the significant changes, skipping the commit-by-commit noise. ## Quick Start Ask the assistant to summarize PR 45 or to summarize the current branch compared to main.
