• hardhat

  Use when creating an R modeling package that needs standardized preprocessing for formula, data frame, matrix, and recipe interfaces. Covers: mold() for training data preprocessing, forge() for prediction data validation, blueprints, model constructors, spruce functions for output formatting.

• metaprogramming

  Use when writing R code that manipulates expressions, builds code programmatically, or needs to understand rlang's defuse/inject mechanics. Covers: defusing with expr()/enquo()/enquos(), quosure environment tracking, injection with !!/!!!/{{, symbol construction with sym()/syms(). Does NOT cover: da

• r-languageserver

  Use when navigating, reading, or refactoring R code: finding where an R function is defined or called, tracing call hierarchies, finding a function's callers before changing it (impact analysis), looking up a function's documentation, or interpreting the lint diagnostics that appear after editing R

• rlang-conditions

  Use when developing R packages that need to handle errors, warnings, and conditions properly. Covers: (1) cli_abort/cli_warn/cli_inform for throwing conditions with formatting, (2) Error call context with caller_env() and caller_arg(), (3) Input validation helpers that report the right function, (4)

• targets-pipelines

  Use when writing complex targets pipelines with branching, batching, or custom target factories. Symptoms: multiple similar targets, parameter sweeps, method comparisons, simulation studies. Covers: static branching (tar_map/tar_combine), dynamic branching (pattern argument), hybrid patterns, custom

• tidy-evaluation

  Use when programming with tidyverse data-masked functions (dplyr, ggplot2, tidyr) and need to pass column references through functions. Covers: forwarding patterns with {{ and ..., names patterns with .data/.env pronouns, bridge patterns with across()/all_of(), double evaluation and ambiguity pitfal
