The skill is a coherent local Git report generator, but crafted report parameters could be inserted into Bash commands and run unintended shell code.
Review before installing. This skill does not appear to exfiltrate data or persist itself, but it will inspect local repository metadata and work-in-progress state. Avoid using untrusted or oddly formatted values for --author or day counts until the command templates add strict validation or structured argument passing, and be cautious in repositories with sensitive commit messages, branch names, stash entries, or contributor emails.
