Cran Extrachecks

The cran-extrachecks skill enables AI agents to perform additional checks on CRAN (Comprehensive R Archive Network) packages beyond standard metadata validation. It helps ensure package integrity, security, and compliance with specific community standards before installation or usage in production environments.

When to use it

• Before deploying a new R package in a regulated environment where strict security policies apply.
• When auditing third-party R libraries for known vulnerabilities or deprecated dependencies.
• During CI/CD pipelines to automatically flag packages failing custom quality gates.
• When verifying that a package adheres to specific community guidelines not covered by default checks.

Key capabilities

• Performs extended validation beyond standard CRAN metadata.
• Checks for potential security issues and deprecated components.
• Validates compliance with additional community-defined standards.
• Provides detailed reports on package health and reliability.

Example prompts

• "Run extra checks on the 'dplyr' package before installing it in our production R environment."
• "Audit this CRAN package for known vulnerabilities and deprecated functions using cran-extrachecks."
• "Validate that the 'ggplot2' package meets our custom security and quality standards."

Tips & gotchas

Ensure your AI agent has network access to fetch the latest CRAN package metadata before running checks. This skill is designed for R packages only; attempting to use it with non-R libraries will result in errors or incomplete validation.
