What problem does it solve?
This Skill helps you identify whether a Rust workspace’s cross-crate API boundaries are clean and intentional by finding which crates export what, which consumers actually use it, and where declared public surface is dead or misleading.
Core Features & Use Cases
- Workspace-wide import/export audit: Builds a consumer→producer edge matrix, then cross-checks declared
pub use re-exports against dead-public findings to classify live facades vs dead facades vs dead canonical pubs.
- Single-crate deep dive: Maps a crate’s root-level module visibility, declared re-exports, imports, and cross-crate dead-pub items to assess encapsulation discipline and API hygiene.
- Hot-symbol forensics: Uses symbol-level usage summaries to determine whether dependencies are pulled broadly or heavily, and to support targeted refactoring decisions.
- Optional architecture metrics: Provides Martin-style dependency instability and abstractness metrics to help prioritize architectural cleanup.
Quick Start
Run rmc-imports-exports on your Rust workspace directory to generate a severity-ranked report of dead and over-broad cross-crate import/export surfaces.
