SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Traditional code search often fails to capture semantic intent, making it hard to find relevant implementations, understand usage, or trace callers in large codebases.

Core Features & Use Cases

  • Hybrid semantic/lexical code search with neural reranking for accurate results.
  • Single-repo and cross-repo queries, symbol graph lookups, and memory tools for knowledge capture.
  • Use cases include locating implementations, understanding code workflows, discovering relationships, and storing insights for future reuse.

Quick Start

Run a cross-repo search to locate a function by name and inspect its usage across projects.

FAQPage Schema
How do I perform cross-repo code search to find function implementations across multiple repositories?

Cross-repo code search locates function implementations across multiple repositories by running hybrid semantic and lexical queries with neural reranking. It exposes interfaces like repo_search to handle cross-repo queries and trace usage across projects accurately.

What is semantic code search and how does it differ from standard lexical search?

Semantic code search captures underlying intent rather than exact string matches, differing from lexical search by using neural reranking. Combining both techniques in a hybrid approach yields faster, more accurate results for locating relevant implementations and workflows.

Can I use a symbol graph to discover code relationships and trace callers in a large codebase?

Yes, you can use a symbol graph to discover code relationships and trace callers in a large codebase. The feature provides symbol graph lookups to map relationships, helping developers understand workflows and find relevant usage patterns.

Does this code analysis tool support storing insights for future reuse during history exploration?

Yes, the code analysis tool supports storing insights for future reuse through memory-backed knowledge retrieval. It includes specific memory tools designed for knowledge capture, allowing developers to save and retrieve context during history exploration.

What is the best way to understand code workflows and locate specific implementations in a single repo?

The best way to understand workflows and locate implementations in a single repo is using hybrid semantic and lexical queries with neural reranking. Single-repo queries accurately trace callers and map symbol relationships within the codebase.
