Does it handle Posit-specific licensing requirements?

Yes, it includes logic for packages in Posit-related GitHub organizations to ensure the correct copyright holder and funder roles are applied to the Authors field.

How does it handle URL validation?

It uses the urlchecker package to find non-HTTPS links and redirecting URLs that cause rejections, while intelligently ignoring 'aspirational' URLs like CRAN badges that only work after publication.

Why do I need this if I already use devtools::check()?

Many CRAN requirements are ad-hoc and enforced manually by reviewers. This skill catches common 'human-checked' errors like Title redundancy, Title Case formatting, and mandatory return value documentation that standard checks miss.

Does it automatically modify my package source code?

No. The skill identifies issues and proposes specific changes (like updating roxygen2 tags or DESCRIPTION fields), but it will only implement those edits once you provide explicit approval.

Does it help with NEWS and README files?

Yes, it ensures NEWS.md and cran-comments.md are present, and checks README files for common pitfalls like relative links that break on CRAN's web interface.

Automates mandatory checks and fixes for R packages to ensure compliance with CRAN's strict ad-hoc submission requirements.

概要

This skill helps R package developers navigate the rigorous CRAN submission process by identifying and fixing common issues that standard tools like devtools::check() often miss. It systematically reviews the DESCRIPTION file for title case and length, ensures all exported functions have mandatory @return and @examples tags, validates HTTPS URLs, and handles administrative requirements like copyright roles. By automating these 'hidden' rules, it reduces the likelihood of manual rejection from CRAN reviewers and streamlines the publication workflow for R developers.
