AI-friendly semantic code search engine for large codebases. Combines ripgrep speed with tree-sitter AST parsing.
Commands
Search
probe search query— Semantic code search with Elasticsearch-style queries
Extract
probe extract code— Extract code blocks with full AST context
Symbols
probe symbols list— List all symbols in files with line numbers
Query
