Rust Analyzer Agent Skill

When to use

MUST use the MCP tools when the task involves:

• Resolving where a symbol is defined, including across crate boundaries
• Finding all references to a function, type, field, or trait method
• Inspecting type signatures, inferred types, or trait implementations
• Searching for symbols by name across a workspace
• Renaming a symbol across all usage sites

SHOULD prefer the MCP tools over grep or file reads when the task requires Rust-aware semantic understanding (scoping, imports, trait dispatch, macro expansion).

Fall back to grep or file reads when the task is not Rust-specific, targets string literals or comments, or covers files outside the Rust compilation.
