Rust Symbol Analyzer

What it does

This skill enables AI agents to parse and analyze Rust source code files, extracting structured symbol information such as functions, structs, and methods. It provides a programmatic way to understand code topology without manual inspection.

When to use it

• Codebase Navigation: Quickly locate specific modules or dependencies within a large Rust project.
• Dependency Analysis: Identify external crates used in a specific function or file.
• Refactoring Support: Map out call graphs to understand the impact of changing a specific struct or trait.
• Documentation Generation: Automatically extract symbol signatures for generating API docs.

Key capabilities

• Parses Rust source files into an internal representation.
• Extracts detailed metadata for functions, structs, enums, and traits.
• Supports filtering symbols by visibility (public/private) and attributes.
• Returns structured JSON data suitable for further processing or display.

Example prompts

• "Analyze src/main.rs and list all public functions along with their signatures."
• "Find every struct in the project that derives the Serialize attribute."
• "Extract the call graph starting from the run function in lib.rs."

Tips & gotchas

Ensure the target file is valid Rust code; syntax errors may cause parsing failures. For large projects, consider splitting analysis into smaller chunks to avoid memory overhead.
