# 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 1. **Notation**: Use standard EBNF notation for grammar specifications 2. **Disambiguation**: Make grammars unambiguous or document precedence rules 3. **Parser Class**: Design grammar to fit target parser class (LL(k), LALR, PEG) 4. **Examples**: Include examples for all grammar rules 5. **Evolution**: Plan for backwards-compatible grammar evolution ## Output Schema ```json { "type": "object", "properties": { "notation": { "type": "string", "enum": ["ebnf", "bnf", "peg", "antlr"] }, "parserClass": { "type": "string", "enum": ["ll1", "llk", "lalr", "glr", "peg"] }, "productionCount": { "type": "integer" }, "conflicts": { "type": "array", "items": { "type": "string" } }, "generatedFiles": { "type": "array", "items": {...
