Instructions onlySoftware Development

AI-generated overview

Navigates Rust code with LSP operations such as go-to-definition, find references and hover.

What it does: This skill guides an agent through using Language Server Protocol operations to navigate Rust codebases. It covers go-to-definition, find-references, hover information, workspace symbol search and document symbols, and it defines output formats for reporting definitions and references. It also lists common user phrasings mapped to the matching LSP operation and error handling for missing servers or ambiguous symbols.
When to use it: Use it when someone asks where a Rust symbol is defined, who uses it, or what type it has. It is also suited to pre-refactoring impact checks and exploring large Rust projects.
Requirements: Requires an LSP tool and a running rust-analyzer server, plus Read and Glob access to the workspace. No scripts are shipped; the skill is instructions only.

Rust Code Navigator

Navigate large Rust codebases efficiently using Language Server Protocol.

Usage

Examples:

/rust-code-navigator parse_config - Find definition of parse_config
/rust-code-navigator MyStruct in src/lib.rs:42 - Navigate from specific location

LSP Operations

1. Go to Definition

Find where a symbol is defined.

Use when:

User asks "where is X defined?"
User wants to understand a type/function
Ctrl+click equivalent

2. Find References

Find all usages of a symbol.

Use when:

User asks "who uses X?"
Before refactoring/renaming
Understanding impact of changes

3. Hover Information

Get type and documentation for a symbol.

Use when:

User asks "what type is X?"
User wants documentation
Quick type checking

Workflow

User: "Where is the Config struct defined?"    │    ▼[1] Search for "Config" in workspace    LSP(operation: "workspaceSymbol", ...)    │    ▼[2] If multiple results, ask user to clarify    │    ▼[3] Go to definition    LSP(operation: "goToDefinition", ...)    │    ▼[4] Show file path and context    Read surrounding code for context

Common Patterns

Error Handling

Error	Cause	Solution
"No LSP server"	rust-analyzer not running	Suggest: `rustup component add rust-analyzer`
"Symbol not found"	Typo or not in scope	Search with workspaceSymbol first
"Multiple definitions"	Generics or macros	Show all and let user choose
