Is this skill specific to Claude Code?

Yes, this is a specialized Claude Code Skill designed to enhance Claude's behavior and domain-specific knowledge during development sessions.

Do I need the pest crate installed to use this?

Yes, this skill generates code specifically designed for the pest and pest_derive crates in the Rust ecosystem.

Can it help me debug existing grammars?

Absolutely. It can analyze your current .pest rules to identify ambiguities, infinite loops, or logical errors in your parsing logic.

How does this skill help with Rust development?

It automates the creation of .pest grammar files and the corresponding Rust implementation code, significantly reducing boilerplate and syntax errors.

What is a PEG parser?

A Parsing Expression Grammar (PEG) is a type of analytic grammar that describes a formal language via a set of rules for recognizing strings, offering more power than regular expressions.

Developer Tools

Generates robust PEG grammars and Rust parser implementations using the pest library.

About

The Pest Specialist skill equips Claude with deep expertise in the pest parsing library for Rust, enabling it to design, write, and debug complex Parsing Expression Grammars (PEG). It streamlines the development process by generating precise .pest grammar files and the corresponding Rust boilerplate code needed to transform raw input into structured data. This skill is essential for developers building custom DSLs, complex configuration parsers, or data transformation tools where standard regular expressions fall short.
