This parses LSP symbols from your Rust codebase to give you a structural overview of what's where. It'll show you all structs, traits, functions, and enums across the project or drill into a single file with hierarchy. Useful when you're dropped into an unfamiliar codebase or need to audit what's public before a release. The output includes tables with locations, visibility, and relationship info. It can filter by symbol type and attempts complexity metrics based on function count and lines. Honestly most valuable for that initial "what am I looking at" moment rather than ongoing development, since your IDE already does symbol search, but the cross-file categorization view is handy for documentation or onboarding.
