Why does this skill use a scratch repository?

The GitHub CLI currently does not support direct image uploads to comments. Using a scratch repository allows the agent to host images and generate public URLs for markdown embedding.

Does the scratch repository need to be public?

Yes, for images to render correctly for all users in GitHub markdown comments, the scratch repository should be public so the raw content URLs are accessible.

Is the GitHub CLI required for this skill?

Yes, this skill relies on the 'gh' command-line tool to authenticate and post comments containing the generated image links.

Can I use this for multiple projects?

Absolutely. The skill uses a naming convention (org_repo_number) to organize images for various repositories and issues within a single scratch repo.

About

This skill provides a standardized workflow for Claude to handle visual assets during the software development lifecycle. Since command-line interfaces often lack native support for direct image uploads to GitHub comments, this skill utilizes a 'scratch' repository to host images. It automatically organizes files by repository and issue number, generates raw content URLs, and uses the GitHub CLI to embed them into PRs or issues. It is ideal for automated agents that need to provide visual evidence of UI changes, bug reports, or documentation updates.
