Language Server Protocol

This skill helps developers implement the Debug Adapter Protocol (DAP) to integrate debuggers into editors like VS Code. It handles core debugging features including breakpoints, stepping, stack traces, and variable inspection. Use it when building or extending a debug adapter for a custom language or runtime.

This skill enables generating and consuming source maps for debugging compiled code, supporting formats like V3 JSON and DWARF. It handles mapping generated positions to original source, inlined functions, and source map composition. Use it when developing compilers, debuggers, or JIT compilers to maintain accurate debugging information.

This Claude skill helps developers create Tree-sitter grammars for incremental parsing and syntax highlighting. It can write grammar files, implement external scanners, design syntax queries, and integrate with editors like VS Code and Neovim. Use it when building or extending language support for editors and tools that leverage Tree-sitter.

This skill helps developers build interactive REPLs with features like readline editing, multi-line input, and tab completion. It's ideal for creating language interpreters, development consoles, or tools requiring incremental code evaluation. Use it when implementing persistent REPL states, expression evaluation, or special commands like :help and :type.
