# REPL Development Skill ## Overview Expert skill for building interactive REPLs with rich editing and evaluation features. ## Capabilities - Implement readline integration with history - Handle multi-line input detection - Implement tab completion for identifiers - Design incremental compilation for REPL - Handle top-level expression evaluation - Implement persistent REPL state - Design pretty-printing for values - Support special REPL commands (:help, :type, etc.) ## Target Processes - repl-development.js - interpreter-implementation.js - lsp-server-implementation.js ## Dependencies - rustyline - readline libraries - linenoise ## Usage Guidelines 1. **Line Editing**: Use established readline libraries for robust line editing 2. **Multi-line**: Detect incomplete expressions for multi-line input 3. **Completion**: Implement context-aware tab completion 4. **History**: Persist history across sessions 5. **Commands**: Provide useful meta-commands (:help, :type, :quit, etc.) ## Output Schema ```json { "type": "object", "properties": { "lineLibrary": { "type": "string", "enum": ["readline", "rustyline", "linenoise", "custom"] }, "features": { "type": "array", "items": { "type": "string" } }, "commands": { "type": "array", "items": { "type": "object", "properties": { "name": { "type": "string" }, "description": { "type": "string" } } } }, "generatedFile...
