Grammar Design Skill
Overview
Expert skill for formal grammar design including disambiguation, precedence, and validation.
Capabilities
- Write EBNF/BNF grammar specifications
- Design unambiguous grammars
- Handle operator precedence and associativity
- Analyze grammar conflicts
- Design grammar for specific parser classes (LL, LR, PEG)
- Document grammar with examples
- Design syntax for common language constructs
- Handle grammar evolution and backwards compatibility
Target Processes
- language-grammar-design.js
- lexer-implementation.js
- parser-development.js
Dependencies
Parsing theory literature (Dragon Book, Parsing Techniques)
Usage Guidelines
- Notation: Use standard EBNF notation for grammar specifications
- Disambiguation: Make grammars unambiguous or document precedence rules
- Parser Class: Design grammar to fit target parser class (LL(k), LALR, PEG)
- Examples: Include examples for all grammar rules
- Evolution: Plan for backwards-compatible grammar evolution
