R Dev Agent
- Updated April 29, 2026
- matheus-rech/r-dev-agent
r-dev-agent is a Claude Code plugin marketplace that provides an R development agent and R language server so developers can build packages, Shiny apps, and Quarto projects with LSP-backed assistance.
About
r-dev-agent marketplace publishes r-dev and r-lsp plugins that bring first-class R support to Claude Code with project auto-detection, LSP diagnostics, and disciplined testthat behavior. The agent reads DESCRIPTION, Shiny, or Quarto markers, delegates to tidyverse and testing skills when present, and can pair with the btw MCP server for deeper docs. Install it when you write R packages, Shiny apps, or Quarto projects inside Claude Code and need more than generic polyglot assistance.
- r-dev agent detects packages, Shiny, Quarto, and Rmd projects
- Strict rules: fix implementation when tests fail, not tests
- r-lsp adds diagnostics, navigation, hover, and completions
- Optional btw MCP server for on-demand R documentation

FAQ
Which plugins are included?
README lists r-dev for R development tasks and r-lsp for diagnostics, go-to-definition, hover, and completions.
What test rules does the agent follow?
It may add tests but cannot alter assertions, delete tests, add skips, or mock failures away—implementation must change instead.
What R packages should be installed first?
Quick start recommends languageserver, devtools, testthat, roxygen2, pak, and optionally posit-dev/btw via pak.
