Security
1 medium severity finding. This skill can be installed but you should review these findings before use.
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Third-party content exposure detected (high risk: 0.90). The skill explicitly fetches live diffs from public GitHub (railsdiff via the GitHub API URL https://api.github.com/repos/railsdiff/rails-new-output/compare/v{CURRENT}...v{TARGET} in Step 2) and the provided script fetches Rails CHANGELOGs from raw.githubusercontent.com, and those public, user-maintained sources are read and interpreted by the workflow to drive upgrade decisions and actions.
