| description | Use this skill when the user wants to search code semantically, extract code blocks with AST context, find patterns using tree-sitter, or analyze code structure. |
Probe Plugin
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
probe query ast — AST-based structural pattern matching
Usage Examples
Basic search:
probe search "authentication" ./src
probe search "error AND handling" ./
probe search "login OR auth" ./src
Extract code:
probe extract src/main.rs:42
probe extract src/main.rs#authenticate
probe extract src/main.rs:10-50
List symbols:
probe symbols src/main.rs
probe symbols src/main.rs --format json
AST pattern matching:
probe query "async fn $NAME($$$)" --language rust
probe query "function $NAME($$$)" --language javascript
Installation
npm install -g @probelabs/probe
Or via curl:
curl -fsSL https://raw.githubusercontent.com/probelabs/probe/main/install.sh | bash
