What problem does it solve? Manual edit summaries are hard to read and easy to misinterpret when reviewing code or text changes. This Skill produces real, shareable diffs—either an interactive viewer URL or a rendered file artifact—so reviewers see exactly what changed. ## Core Features & Use Cases - Viewer URLs: Render an interactive gateway-hosted diff viewer with mode=view, then present it via the canvas tool. - File Artifacts: Render diffs to PNG or PDF files with mode=file, with quality presets (standard, hq, print) and scale/width overrides. - Flexible Input: Accepts either before + after text or a unified patch string, with optional path for file naming. - Use Case: After refactoring a function, generate a diff of the old and new versions and deliver the rendered PNG to a chat channel using the message tool with the returned filePath. ## Quick Start Use the diffs tool to show the changes between the original and edited versions of config.yaml as a shareable viewer link.
