Automated summary
This skill guides the assistant to write modern, readable R code, favoring tidyverse conventions and the here package for file paths.
Strengths
- Enforces tidyverse style (naming, spacing, structure) consistently
- Gives concrete practices: here:: for paths, explicit library() calls, fully qualified calls for less common packages
- Includes a lintr:: style check before finishing a task
- Composes with companion analysis and visualization skills
Limitations
- Does not cover R installation or environment management
- Assumes the user's environment has here and lintr available
- Says little about non-tidyverse approaches such as base R, data.table, or Bioconductor packages
Use it whenever writing or editing R code, especially tidyverse-based data analysis.
Avoid it for R work that intentionally relies on base R or data.table, or for tasks unrelated to R.
Security analysis
SafeThe skill is purely an R coding style guide. It references benign packages (tidyverse, here, lintr) and contains no shell commands, file deletion, network calls, credential handling, or obfuscated instructions. No execution risk beyond normal code generation.

R's Little Helper
Purpose
You assist the user in programming in R. This document captures current best practices for R development, emphasizing modern tidyverse patterns and style.
Core Principles
-
Use modern tidyverse patterns - Prioritize dplyr 1.1+ features, magrittr pipes, and current APIs
-
Follow tidyverse style guide - Consistent naming, spacing, and structure
-
Focus on clarity and readability - Write code first for clarity and human interpretability.
Instructions
Paths
- Use
here::library for specifying paths
Libraries
- Use
tidyverse::library to load core library - For common libraries, you may reference functions directly (e.g.
select()). For less common libraries, reference functions using full path (e.g.janitor::clean_names()) - Libraries should be loaded with
library()statement regardless of how they are referenced in code.
Formatting
- Keep your code well formatted and styled.
- Use the style from https://style.tidyverse.org
- Before completing a task, use
lintr::package to confirm that you comply with style.

From the file to a first result
The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.
View the source and supporting filesThis download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.
1. Download the file
Download SKILL.mdFrom the root of a test project, save the file as .skill-downloads/r-s-little-helper-mrzxuq8l/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.
Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.
mkdir -p '.skill-downloads/r-s-little-helper-mrzxuq8l' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/r-s-little-helper-mrzxuq8l/download' --output '.skill-downloads/r-s-little-helper-mrzxuq8l/SKILL.md.part' && mv '.skill-downloads/r-s-little-helper-mrzxuq8l/SKILL.md.part' '.skill-downloads/r-s-little-helper-mrzxuq8l/SKILL.md'2. Check prerequisites
Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.
No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.
The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.
3. Load the skill
After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.
Official OpenSkills installationopenskills install './.skill-downloads/r-s-little-helper-mrzxuq8l'openskills read 'r-s-little-helper-mrzxuq8l'Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.
For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.
openskills syncManual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.
4. Try a first task
Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:
Read .skill-downloads/r-s-little-helper-mrzxuq8l/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.

Development
Master React Hook Form: avoid anti-patterns, manage subscriptions, and handle reset, dirty state, and controlled inputs correctly.
Emotion to Mantine Migration
Development
Migrate Emotion styled-components to Mantine components with style props and CSS modules. Use when converting .styled.tsx files or removing @emotion imports.
Scope Creep Detector
Development
Analyzes git diffs against a stated intent to detect scope creep, unrelated files, broad PRs, and oversized changes, then suggests keep, split, or justify actions.
