Prepare R packages for CRAN submission by checking for common ad-hoc requirements not caught by devtools::check(). Use when: (1) Preparing a package for first CRAN release, (2) Preparing a package update for CRAN resubmission, (3) Reviewing a package to ensure CRAN compliance, (4) Responding to CRAN reviewer feedback. Covers documentation requirements, DESCRIPTION field standards, URL validation, examples, and administrative requirements.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'r-cran-extrachecks' ] || [ -L ~/.agents/skills/'r-cran-extrachecks' ]; then echo 'A skill folder named r-cran-extrachecks already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/posit-dev/skills' "$d" && git -C "$d" checkout --quiet '951959403f4ecc9d0274adf35538fc67153b6f31' -- 'r-lib/r-cran-extrachecks' && mkdir -p ~/.agents/skills && cp -R "$d"/'r-lib/r-cran-extrachecks' ~/.agents/skills/'r-cran-extrachecks' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'r-cran-extrachecks' ~/.claude/skills/'r-cran-extrachecks' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
