AI-generated overview

Analyzes Rust project structure by listing symbols such as structs, traits, functions and modules via LSP queries.

What it does: The skill inspects Rust source files and reports their symbol structure, using LSP documentSymbol and workspaceSymbol operations to enumerate modules, structs, enums, traits, functions and methods. It produces structured output such as project trees, tables of symbols by type, single-file symbol hierarchies, complexity metrics and internal dependency lists. It is instruction-only and ships no scripts.
When to use it: Use it when you want an overview of a Rust codebase's structure or a listing of its structs, traits, functions or modules. It also fits questions about a single file's symbol hierarchy, complexity hotspots or internal import relationships.
Requirements: An agent environment with LSP, Read and Glob tools available, plus a Rust project whose language server can answer symbol queries.

Rust Symbol Analyzer

Analyze project structure by examining symbols across your Rust codebase.

Usage

Examples:

/rust-symbol-analyzer - Analyze entire project
/rust-symbol-analyzer src/lib.rs - Analyze single file
/rust-symbol-analyzer --type trait - List all traits in project

LSP Operations

1. Document Symbols (Single File)

Get all symbols in a file with their hierarchy.

Returns: Nested structure of modules, structs, functions, etc.

2. Workspace Symbols (Entire Project)

Search for symbols across the workspace.

Note: Query is implicit in the operation context.

Workflow

User: "What's the structure of this project?"    │    ▼[1] Find all Rust files    Glob("**/*.rs")    │    ▼[2] Get symbols from each key file    LSP(documentSymbol) for lib.rs, main.rs    │    ▼[3] Categorize by type    │    ▼[4] Generate structure visualization
