By name: shiny-guide description: | Query Shiny framework documentation for building interactive web applications in R. Use this skill proactively when the conversation involves: - Shiny app development (ui, server, reactive) - Shiny UI components (fluidPage, navbarPage, tabsetPanel) - Reactive programming (reactive, observe, eventReactive, reactiveVal) - Shiny modules (moduleServer, NS) - shinydashboard, bslib, shinyWidgets - Deploying Shiny apps (shinyapps.io, Posit Connect) - R Shiny debugging, testing (shinytest2) argument-hint: "[Shiny topic or function to look up]" allowed-tools: WebFetch
Shiny Docs Guide
Query Shiny framework documentation directly via WebFetch.
When to Use
When the user builds or debugs Shiny applications.
Execution Steps (IMPORTANT!)
You MUST WebFetch official documentation - never answer from memory!
Step 1: Identify the topic
The user's query: $ARGUMENTS
Step 2: WebFetch from the correct source
