rmc-crate-audit

What problem does it solve?

Identifies dead or misleading public API surfaces and highlights structural and complexity risks in a Rust crate so teams can prioritize safe cleanup and refactors.

Core Features & Use Cases

• Crate-scoped structural audit: builds a module tree snapshot, re-export map, and dead-public detection, then cross-tabulates them to find dead canonical items and dead facade re-exports.
• Dependency direction analysis: determines outgoing vs incoming dependencies to assess whether the crate is single-purpose or a shared library with strong coupling.
• Complexity-driven prioritization: runs file-aggregated complexity analysis and links hot spots to usage summaries to target changes that matter most.
• Public surface validation: confirms whether root-level canonical types and key methods have real external fan-in using usage queries, flagging test-only or empty targets.
• Method-level deepening (Layer 4): analyzes types’ methods for unused or critical-path fan-in with visibility derived from source spans.

Quick Start

Run rmc-crate-audit for the crate name you want and the workspace path to generate a severity-ranked findings table and recommended actions.
