# Parser Generator Skill ## Overview Expert skill for parser generation and implementation using LL, LR, LALR, PEG, and Pratt parsing techniques. ## Capabilities - Generate parsers from grammar specifications (ANTLR, Bison, tree-sitter) - Implement recursive descent parsers with predictive parsing - Implement Pratt parsers for expression handling - Generate LALR/GLR parse tables - Implement PEG parsers with packrat memoization - Handle grammar conflicts (shift-reduce, reduce-reduce) - Generate concrete syntax trees (CST) and AST transformations - Implement operator precedence parsing ## Target Processes - parser-development.js - language-grammar-design.js - ast-design.js - lsp-server-implementation.js ## Dependencies - ANTLR4 - tree-sitter - Bison/Yacc ## Usage Guidelines 1. **Grammar Analysis**: Analyze grammar class requirements (LL(k), LALR, etc.) before selecting parser type 2. **Conflict Resolution**: Document and resolve all shift-reduce/reduce-reduce conflicts explicitly 3. **Error Recovery**: Implement synchronization points for robust error recovery 4. **AST Construction**: Design AST node types before implementing production actions 5. **Expression Parsing**: Use Pratt pa

About this skill
What does the Parser Generator skill do?

Expert skill for parser generation and implementation using LL, LR, LALR, PEG, and Pratt parsing techniques

How do I install it?

Run `npx skills add a5c-ai/babysitter --skill parser-generator --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From a5c-ai/babysitter, a repository with 1,642 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
