SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps developers write correct, idiomatic tidyjs pipelines and avoids common misuses such as relying on string accessors, misplacing mutate vs mutateWithSummary, and misunderstanding groupBy export modes.

Core Features & Use Cases

  • Enforces proper usage of tidyjs verbs (filter, mutate, mutateWithSummary, groupBy, summarize, pivot, etc.).
  • Guides accessor patterns and documentation navigation for reliable code.
  • Provides quick-start guidance and pointers to mental model and reference docs for typical data-wrangling tasks.

Quick Start

Start by reading the mental model and quick-reference docs, then apply a simple tidyjs pipeline to a sample dataset.

FAQPage Schema
How do I fix incorrect tidyjs code patterns for filtering and mutating data in JavaScript?

Use mutateWithSummary when your tidyjs pipeline needs computed values available across grouped rows, and mutate for simple row-level transformations. Misplacing them causes incorrect data wrangling, so this skill enforces proper verb placement for reliable pipelines.

Why does my tidyjs groupBy export mode produce unexpected output in JavaScript data wrangling?

Your tidyjs groupBy export mode produces unexpected output due to misunderstanding the export configurations. This skill corrects groupBy misuse by guiding proper accessor patterns and documentation navigation for accurate summarizing and grouping operations.

Can I use tidyjs for pivoting and joining datasets in JavaScript projects?

Yes, you can use tidyjs for pivoting and joining datasets in JavaScript projects. This skill provides guidance on idiomatic verb usage across data-wrangling tasks, ensuring your pipelines for filtering, grouping, and summarizing are clean and safe.

What is the best way to structure tidyjs pipelines for data wrangling in JavaScript?

The best way to structure tidyjs pipelines is by reading the mental model and quick-reference docs first, then applying verbs correctly. This skill enforces documentation structure and safety checks to ensure clean, idiomatic JavaScript data transformations.

Do I need specific dependencies to build safe tidyjs pipelines for data transformations?

No specific dependencies are required beyond tidyjs itself to build safe pipelines. This skill ensures frontmatter completeness and guides component presence and safety checks, allowing you to correct data-wrangling code patterns without external tools.
