Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned posit-dev/skills at 1bb49b8eec.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

What it does

This skill enables AI agents to apply custom theming styles to Shiny applications built with bslib. It allows dynamic modification of layout, colors, and typography directly within the R environment.

When to use it

  • You need to match a Shiny app's visual identity to your organization's brand guidelines without hardcoding CSS.
  • You want to create reusable theme configurations that can be toggled or updated programmatically across multiple apps.
  • You are building dashboards where the same underlying data visualization needs different aesthetic treatments for distinct user groups.

Key capabilities

  • Applies bslib-based themes to Shiny UIs dynamically.
  • Modifies layout structures and component styling via R code.
  • Facilitates consistent design patterns across diverse Shiny applications.

Example prompts

  • "Apply a dark mode theme to this Shiny app using the shiny-bslib-theming skill."
  • "Create a custom corporate theme for my dashboard that uses specific blue and gray color palettes defined in R."
  • "Update the typography and spacing of this existing Shiny interface to match a new design system."

Tips & gotchas

Ensure your Shiny app is already utilizing bslib as its layout engine, as this skill relies on those underlying structures. While powerful for customization, complex theme overrides may require advanced knowledge of CSS variables and R list manipulation to resolve conflicts effectively.
