rmc-symbol-forensics

What problem does it solve?

This Skill helps you understand the real-world impact of a Rust symbol by locating where it is imported, referenced, and referenced via rust-analyzer cross-links, so you can make safer refactor or deletion decisions.

Core Features & Use Cases

• Single-symbol deep dive: Produces a structured forensics report for one qualified symbol, including its declaration context and downstream usage patterns.
• Import and usage intelligence: Compares who_imports, who_uses, and who_uses_summary to distinguish structural import-only presence from non-import references, including Test/Other consumer breakdowns.
• Verification via rust-analyzer references: Uses find_references to catch additional reference types that hypergraph indexing might miss (e.g., macro-introduced or cfg-gated cases).
• Risk-framing outputs: Applies decision frames (safe-to-delete, test-only, critical-path, shared-API, imported-as-bound) and recommends next actions, optionally extending to type method fan-in.

Quick Start

Ask for a single-symbol report by providing the symbol’s qualified name for a deep dive on its declaration, importers, non-import references, and rust-analyzer cross-references.
